3 EXECUTION

3.1 Examination

3.1.1 Prior to installation, Contractor to ensure, that manufacturer’s clearance

requirements can be met as space is limited space.

3.1.2 Examine fluid cooler, piping and conditions for compliance with requirements

for installation tolerances and other conditions affecting performance.

3.1.3 Examine roughing-in for piping systems to verify actual dimensions and

locations of piping connections before fluid cooler installation.

3.1.4 Proceed with installation only after any unsatisfactory conditions have been

corrected.

3.1.5 Contact manufacturer’s representative for additional instructions where required.

3.2 Demolition and Cleaning

3.2.1 Remove existing fluid cooler and accessories as specified within the drawings

and specifications.

3.2.2 All existing equipment and material not required in the final installation shall be

carefully removed at the appropriate time. Existing unused electrical and

mechanical equipment shall be disconnected from power source and made safe

for removal. Unused conduits, wiring shall be removed.

3.2.3 Legally dispose of all materials removed. Metals shall be routed to a suitable

recycle centre and documentary proof of disposal shall be provided to Toronto

Zoo.

3.3 Installation

3.3.1 Install in accordance with Contract Drawings, manufacturer's instructions and

schematics. Contact manufacturer’s representative for additional instructions




where field conditions may not permit installation per manufacturer’s written

instructions. Install fluid cooler as per manufacturers' instructions. 3.3.2 Coordinate location and installation of:

.1 new vibration isolators

.2 new electrical disconnects

.3 new plumbing and drainage piping

.4 new hydronic system piping.

Adjust locations and elevations to suit field conditions and to ensure proper fluid

cooler operation. 3.3.3 Install with manufacturer-required clearances for service and maintenance.

3.3.4 Attach “Electrical Heat Tracing” label on all heat traced piping over insulation

jacket.

3.3.5 Flexible Pipe Connectors:

.1 Install when fluid cooler is full of water and the vibration isolators are

levelled, adjusted.

.2 Install without twisting and offset. Avoid torque when installing NTP

connections.

.3 Support pipe rigidly and independently at both ends.

3.3.6 Painting:

.1 Remove dirt and grease with mineral spirits and wipe dry with clean

paper towels.

.2 Remove rust, scale using sandpaper, wire brush. Grind welds to clean

metal surface.

.3 Apply paint as per manufacturers’ recommendations, observing

allowable ambient temperatures.

3.4 Electrical Work

3.4.1 Provide all material, equipment, and labour required for a complete and

adequate installation. Make all necessary allowances in tender price for

removal, relocation, rerouting, reconnection of existing electrical equipment,

and wiring as may be necessary for the execution and completion of this project.

No allowance will be made later for any expense incurred through failure to

make this examination.

3.4.2 Remove and/or relocate and reinstall all wiring, fixtures, and equipment as

necessary to accommodate alterations. Wiring located in areas being altered or

demolished, but feeding outlets or equipment required to remain in service shall

be rerouted as required to maintain the continuity of these services.

3.4.3 Replace all cabling with plenum-rated, shielded cable, 1.02mm (18 gauge)

minimum.

3.4.4 All wiring shall be run concealed where possible except that conduits in

unfinished areas and on existing walls and ceiling may be installed on surface.

3.4.5 Power shutdown, if required, must be coordinated with Toronto Zoo’s

representative.

3.4.6 Certain items are identified on the Contract Drawings as existing equipment to

be “removed”. Disconnect said equipment and make safe. Obsolete conduits and

cables shall be disconnected from their source of supply, cut back to a suitable

point, and left in place unless they interfere with the new Work, in which case

they shall be removed.

3.4.7 Conduits sizes shall be in compliance with ESA. All surface conduits shall be

installed parallel to the building.

3.4.8 Conduits for panel feeders and branch circuit wiring shall be thin wall Electrical

Metallic Tubing (EMT) conduit.

3.4.9 Provide separate insulated ground conductor in all conduits, as per code.

3.4.10 Minimum conduit size shall be 12.7mm (½ inches).

3.4.11 Contractor to connect new fluid cooler wiring to existing ‘A-A’ panel reusing

the existing branch circuit for fluid cooler and immersion heater.




3.5 Firestop and Smoke Seal

3.5.1 Provide firestop and smoke seal materials around pipe or duct penetration

through floors and fire rated walls and partitions. Pack and seal void between

the sleeve and pipe insulation for the full depth of the sleeve with ULC approved

methods to maintain the integrity of the required fire separation as required by

the Ontario Building Code.

3.5.2 See related Sections:

Section 078400 Fire Stopping

Section 079000 Sealant

3.6 Start up, Testing and Commissioning

components and field installation, including piping and electrical connections

and report any deficiencies.

3.6.2 Engage a factory-authorized service representative to start up, commission fluid

cooler and control accessories and demonstrate system operation and service

requirements for Toronto Zoo and service personnel.

3.7 Balancing

3.6.1 Engage an independent balancing contractor who is a current member of AABC

or NEBB

3.6.2 Balancing scope shall include the following:

.1 Verify pump and fan operation, measure CP-1, CP-2 pump flow, all

motor amperages, fan speed, pressures and temperatures.

.2 Verify correct operation of VFD in response to BAS output to control
