REFRIGERANT CHARGE ADJUSTMENTSLiquid Line Size R-410A Charge oz/ft

3/80.60

(Factory charge for lineset = 9 oz)

5/16 0.40

1/4 0.27

Units are factory charged for 15 ft (4.6 m) of 3/8” liquid line. The factory charge for 3/8” lineset 9 oz. When using other length ordiameter liquid lines, charge adjustments are required per the chart above.

Charging Formula:

[(Lineset oz/ft x total length) – (factory charge for lineset)] = charge adjustment

Example 1: System has 15 ft of line set using existing 1/4“ liquid line. What charge adjustment is required?

Formula: (.27 oz/ft x 15ft) – (9 oz) = (-4.95) oz.

Net result is to remove 4.95 oz of refrigerant from the system

Example 2: System has 45 ft of existing 5/16” liquid line. What is the charge adjustment?

Formula: (.40 oz/ft. x 45ft) – (9 oz.) = 9 oz.

Net result is to add 9 oz of refrigerant to the system

LONG LINE APPLICATIONSAn application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintainacceptable refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining asystem as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor andoutdoor units.

For Air Conditioner systems, the charts below shows when an application requires a TXV and long line accessories due to linesetlength.

AHRI — Air Conditioning, Heating & Refrigeration InstituteEER — Energy Efficiency Ratio − 80�F (26.6�C) indoor db/67�F (19.4�C) indoor wb & 95�F (35�C) outdoor wb.SEER — Seasonal Energy Efficiency RatioTDR — Time−Delay Relay. In most cases, only one method should be used to achieve TDR function. Using more than one method in a system may cause degradation in performance.

Use either the accessory Time−Delay Relay or a furnace equipped with TDR. Most ICP furnaces are equipped with TDR.NOTES:1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included.2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners. Ratings for other combinations are determined under DOE computer

simulation procedures.3. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature.4. Do not apply with capillary tube coils as performance and reliability are significantly affected.
