The all MEX VS units are designed for outdoor installation: any cover over the unit and location near trees (even if they partially cover the unit) has to be avoided in order to prevent air recirculation. It is advisable to create a proper basement, with a size similar to unit foot-print. Unit vibration level is very low: it is advisable however, to fit a rigid rubber band between basement and unit base-frame. It is also possible to install anti-vibration supports (springs or rubbers) to keep vibrations at a very low level. Absolute care has to be taken to ensure adequate air volume to the condenser. Re-circulation of discharge air has to be avoided; failure to observe this point will result in poor performance or activation of safety controls. For these reasons it is absolutely necessary to respect the following clearances:

MOD. A B C D E

CAUTION: It is obligatory to install the unit on a firm and appropriate basement to support its weight.

Considering the weight of the unit, possible vibrations and resultant noise, we do not recommend suspension installion of the unit; in this case, the firm is not responsible for any damage or inconvenience that may result.

7.4 HYDRAULIC CONNECTIONS

The hydraulic connections have to be installed in accordance with national and local regulations; pipes can be made up of steel, galvanized steel or PVC. Pipes have to be designed depending on the nominal water flow and on the hydraulic pressure drops of the system. All pipes have to be insulated with closed-cell material of adequate thickness. Chillers have to be connected to piping by means of flexible joints. Piping should include: • Hole thermometers to monitor the system’s temperature. • Manual gate valves to separate the chiller from the hydraulic circuit. • Y-shaped metallic filter and a dirt separator (to be mounted on the inlet pipe) with a mesh not larger than 1mm. • Charging group and discharge valve, where necessary.

WARNING: Make sure that, when designing the pipe length and diameter, do not exceed the maximum head loss on the plant side, please see the technical data given in the table of Paragraph 12 (available pressure head).

WARNING: Connect the pipes to the attacks by using always key against key system.

WARNING: The expansion vessel have a limited volume. The installator have to provide a further expansion vessel if it is necessary.

WARNING: Unit water inlet pipe have to be in correspondence with the connection labelled: ”WATER INLET”, otherwise the evaporator may freeze.

WARNING: It is compulsory to install on the WATER INLET connection a metallic filter (with a mesh not larger than 1mm) and a dirt separator. the warranty will no longer be valid If the water flow switch was manipulated or altered or if the metallic filter and/or dirt separator were not installed. The filter and the dirt separator have to be kept clean, therefore make sure that are clean after the unit installing the unit, and then check them periodically.

All units are standard supplied with the water flow switch (factory installed). The warranty will be invalidated if the water flow switch was altered, removed, or if the water filter and the dirt separator were not installed on the unit. Please refer to the wiring diagram for the water flow switch electric connections.

Make sur that the heating system and the safety valves must comply with the requirements of EN 12828.

7.4.1 Drainage connection

All the units of MEX VS series have been designed to use their own base as a drain pan; a plastic pipe fitting is standard provided to be installed onto the lower part of the unit in the special housing enabling the connection of a drainage pipe.

Each unit is also provided, on the basement of the hydronic kit (at the heat exchanger side), with a hole that can allow to drain any condensed water can leach from plumbing pipes. As the pipes must be well-insulated, the production of condensed water is however very low and therefore the connection of a drainage pipe to that hole is not very required.

7.4.2 Plant circuit charging

WARNING: Verify all the charging/topping up operations.

WARNING: Before beginning the charging/topping up operation of the plant circuit, disconnect the unit for the electric power supply.

WARNING: The charging/topping up of the plant circuit must always be done under controlled conditions of pressure (max 1 bar). Make sure that you have installed on the line of charging/topping up a pressure reducerdevice and a relief valve.

WARNING: The water on the charging/topping up pipe must be suitably pre-filtered from any impurities and suspended particles. Make sure that you have installed a cartridge filter removable. Make sure that an extractable cartridge filter and a dirt separator have been installed.

WARNING: It is required to proceed by air purging periodically in order to eliminate the accumulated air from the plant circuit system.

WARNING: Make sure to install an automatic air vent valve at the highest point of the system.

7.8.2 Terminal block and the electric box

The following illustration shows the the removal procedure of the coping plate for the models 112 RH/115 RH, but the same procedure is applicable for the other models

1. Remove the screws connecting the top plate. Two for each side of the unit and other two crews connecting the top plate with the hole-cable plate holder. (For the small sizes, there is only one fixing screw in the controller’s lateral part of the unit)

2. Remove the screws connecting the cover plate of the electric box then proceed to connect wire to the terminal block.

3. Insert the cables PG cable glands located on the side of the unit to take them outside the unit 4. Close the electric box and the top panel of the unit with their fixing screws.

The above operations must be done after turning off the unit and disconnecting it from the power supply (by mean of an appropriate disconnecting switch which should be already mouted by the installer). Operations to be performed by qualified personnel.

Remove the top cover without taking away the holder of hole-cabe plate.

The work is completed, please fix all the removed plates then tighten all screws and washers (if expected).

8 START UP

Before start-up:

Check out the availability of the supplied wiring diagrams and manuals of installed apparatus.

Check out the availability of the electrical and hydraulic diagrams of the plant in which the unit is installed.

Check that the shut-off valves of the hydraulic circuits are open.

Verify that the hydraulic circuit has been charged under pressure and air vented.

Check out that all water connections are properly installed and all indications on unit labels are observed.

Ensure that arrangements have been provided to drain the condensate.

Check out that all power cables are properly connected and all terminals are hardly fixed.

Check that electrical connections are carried out according to the norms in force including grounding.

Check out that the voltage is the one indicated in the unit labels.

Make sure the voltage is within the limits (±10%) of tolerance range.

Check out that crankcase heaters are powered correctly.

Check out that there is no refrigerant leakage.

Check out that all the cover panels are installed in the proper position and locked with fastening screws before start up.


18

WARNING: The unit must be connected to the electrical network and should be in STAND-BY mode (powered) closing the general switch in order to operate the crankcase heaters of the compressor for a minimum of 12 hours before start up. (the heaters are automatically powered when the main switch is switched off). The crankcase heaters are working properly if, after some minutes, the temperature of crankcase’s compressor is about 10°C ÷ 15°C higher than ambient temperature.

WARNING: The weight of the pipes doesn’t load unit structure.

WARNING: Never switch off the unit (for a temporary stop) by switching off the main switch: this component should be used to disconnect the unit from the power supply only for lengthy stoppages (e.g. seasonal stoppages). Besides, failing the power supply, the crankcase’s heaters are not supplied thus resulting in a possible breakdown of the compressors once the unit is switched on.

WARNING: Do not modify the internal wiring of the unit otherwise the warranty will terminate immediately.

WARNING: The summer/winter operating mode have to be selected at the beginning of the related season. Frequent and sudden changes of this seasonal operating mode have to be avoided in order to prevent severe damages to compressors.

WARNING: When you first install and start-up the unit make sure that the unit is working properly in both cooling and heating modes.

9 SHUTDOWNS FOR LONG PERIODS

The types of shutdown depends on the weather of the site where the unit is installed and on the period of the stop. The antifreeze system, if it’s installed, stay on work also with the on-board control unit in “OFF” position. If the time of stop is long and the temperature is low, we recommend to drain the hydraulic circuits or use a mixture of water and glycol. Drain the hydraulic circuits and shutdown the unit with this passage:

Turn off the unit by placing the switch of each unit to "OFF" position.

Close the water valves.

Place the general differential circuit breaker on "OFF" position, if it is installed upstream of the system.

If the temperature drops below 0°C there is serious danger of frost: add a mixture of water and glycol in the plant, otherwise drain the hydraulic circuits of the plant and of the heat pump.

WARNING: the operation, although it was transient, with water temperatures below +5°C is not guaranteed on the basis of the limits set out in Paragraph 15.4. Before you turn the unit on after a long off period, make sure that the temperature of the mixture of water and glycol is higher than or at least equal to + 5°C.

10 MAINTENANCE AND PERIODICAL CONTROLS

WARNING: All the operations described in this chapter HAVE TO BE CARRIED OUT BY TRAINED STAFF ONLY. Before any operation or before entering the inner components of the unit, be sure that the power supply is disconnected. The compressor’s heads and discharge piping are usually at high temperature levels. Be very careful when operating in their surroundings. Aluminium coil fins are very sharp and can cause serious wounds. Be very careful when operating in their surroundings. After maintenance operations, re-install the cover panels, and fix them by means of screws.

The refrigerant circuits must not be filled with different gas other than that indicated on the nameplate. The use of a different refrigerant can cause severe damage to the compressor.

It’s forbidden to use oils other than those specified in this manual. The use of a different oil can cause serious damage to the compressor.

The temperatures of heads and discharge piping of the compressor are usually high.

Be careful when working near condensing coils. The aluminum fins are very sharp and can cause serious injuries.

After the maintenance operations, close the panels tightly with the fastening screws.

15 OPERATION LIMITS

15.1 EVAPORATOR WATER FLOW RATE

The nominal water flow rate is referred to a ∆T equal to 5°C, between the evaporator’s inlet and outlet temperatures. The allowed maximum flow rate is corresponding to ∆T=3°C; higher values may cause too high pressure drops. The allowed minimum water flow rate is corresponding to ∆T=8°C (except for the models MEX VS 15 RH for which a maximum temperature difference of ∆T=6,25°C is allowed and for the model “MEX VS 16 RH” where the maximum temperature difference is 7,5°C). Insufficient values may cause too low evaporating temperatures with the intervention of safety devices which would stop the unit and, in some particular cases, the water can freeze in the evaporator coil causing the refrigeration circuit to break down. We enclosed below a most accurate table showing the minimum flow rates that to ensure for the plate heat exchanger for a the proper operation of unit according to the model (note: the water flow switch is used for preventing the freezing sensor from failure in the case of insufficient water flow but it does not ensure the required minimum flow rate which allows the unit to work properly)

Models MEX VS

15RH 16RH 18RH 18RH 112RH 112TRH 115RH 115TRH

Required minimum water flow rate [m3/h]

Required maximum water flow rate [m3/h]

1,88 2,30 2,87 3,47 3,95 4,37

As a first approach, and in the absence of other detection systems, the proper flow rate for getting the best performance from your unit can be found at maximum speed of the circulator, using the pressure gauges for controlling the pressure difference between the return and the delivery water on the outside water connections of the unit and make sure that such value is equal or less than the static pressure indicated on the curves shown in paragraph 14 for the respective models.

15.2 COLD WATER TEMPERATURE (SUMMER OPERATION)

The allowed minimum temperature at the evaporator’s outlet is 5°C; for more lower temperatures please contact us. In this case contact our company for the feasibility study and evaluation of changes to be made according to your requests. The maximum temperature that can be maintained at the outlet of the evaporator is 25°C. Higher temperatures (up to a maximum of 40°C) can anyway be tolerated during transitions and start-up phases of the system.

15.3 HOT WATER TEMPERATURE (WINTER OPERATION)

Once the system is working at the right temperature, the inlet hot water temperature should not to be lower than 25°C; the lowest values that are not related to transitional or start-up stages may cause system’s malfunction and possible compressor breakdowns. The maximum outlet water temperature have not to exceed 58°C. At this temperature, the power consumption and performance in terms of C.O.P. are enhanced if the outdoor temperature is higher than 5°C, even if the unit is still able to operate up to the limit temperature that are reported in the envelope. For higher temperatures than those pointed out, especially if have a concomitant with the reduction of the water flow rate, it may cause abnormalities to the normal operating of the unit, or the safety devices act in critical cases.

15.4 AMBIENT AIR TEMPERATURE AND SUMMARIZING TABLES

The units are designed and manufactured to operate, in summer operation, with the condensate control, with outdoor air temperatures ranging between -10°C and 46°C. While operating as a heat pump, the allowed range of the outdoor temperature goes from -20°C to 40°C as a function of the water outlet temperature as indicated in the below table.

Operation limits

Ambient temperature Minimum -10°C Maximum +46°C

Water outlet temperature Minimum +5°C Maximum +25°C

CCF: Capacity correction factor IPCF: Input power correction factor WFCF: Water flow rate correction factor PDCF: Pressure drops correction factor

The water flow rate and pressure drop correction factors are to be applied directly to the values given for operation without glycol. The water flow rate correction factor is calculated in order to get the same temperature’s difference that would be obtained without glycol. The pressure drops’ correction factor takes into account the different water flow rate obtained from the application of the water flow rate correction factor.
