REFRIGERANT CHARGE ADJUSTMENTS
Liquid Line Size Puron Charge oz/ft (g/m)
0.60 (17.74)
3/8
(Factory charge for lineset = 9 oz / 266.16 g)
5/16 0.40 (11.83)
1/4 0.27 (7.98)
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 or diameter
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) = (Â4.95) 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 APPLICATIONS
An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable
refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line
depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.
For Air Conditioner systems, the chart below shows when an application is considered Long Line.

TESTED AHRI COMBINATION RATINGS*
NOTE: Ratings contained in this document are subject to change at any time.
For AHRI ratings certificates, please refer to the AHRI directory www.ahridirectory.org
Additional ratings and system combinations can be accessed via the Carrier database at:

* Ratings are net values reflecting the effects of circulating fan heat. Supplemental electric heat is not included. Ratings are based on:
EER — Energy Efficiency Ratio
SEER — Seasonal Energy Efficiency Ratio
TDR — Time-Delay Relay. In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause
degradation in performance. Use either the accessory Time-Delay Relay KAATD0101TDR or a furnace equipped with TDR. Most Carrier 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.

In 3--phase units a small circuit board is factory installed to monitor Factory charge amount and desired subcooling are shown on unit
line voltage. A small led will flash if a phase problem exists. See rating plate. Charging method is shown on information plate inside
code descriptions on monitor. If LED is flashing, disconnect unit. To properly check or adjust charge, conditions must be

(21.11_C and 37.78_C), and the indoor temperature is between
70_F and 80_F (21.11_C and 26.67_C).
For standard refrigerant line lengths (80 ft/24.38 m or less), allow
system to operate in cooling mode at least 15 minutes. If conditions
are favorable, check system charge by subcooling method. If any
adjustment is necessary, adjust charge slowly and allow system to
operate for 15 minutes to stabilize before declaring a properly
charged system.
If the indoor temperature is above 80_F (26.67_C), and the
outdoor temperature is in the favorable range, adjust system charge
by weight based on line length and allow the indoor temperature to
drop to 80_F (26.67_C) before attempting to check system charge
by subcooling method as described above.
If the indoor temperature is below 70_F (21.11_C), or the outdoor
temperature is not in the favorable range, adjust charge for line set

PURONR (R--410A) REFRIGERANT QUICK REFERENCE GUIDE
S Puron refrigerant operates at 50--70 percent higher pressures than R--22. Be sure that servicing equipment and replacement
components are designed to operate with Puron refrigerant
S Puron refrigerant cylinders are rose colored.
S Recovery cylinder service pressure rating must be 400 psig, DOT 4BA400 or DOT BW400.
S Puron refrigerant systems should be charged with liquid refrigerant. Use a commercial type metering device in the manifold hose

3/8
(Factory charge for lineset = 9 oz / 266.16 g)
5/16 0.40 (11.83)
1/4 0.27 (7.98)
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 or diameter
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) = (Â4.95) 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 APPLICATIONS
An application is considered Long Line, when the refrigerant level in the system requires the use of accessories to maintain acceptable
refrigerant management for systems reliability. See Accessory Usage Guideline table for required accessories. Defining a system as long line
depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.
For Air Conditioner systems, the chart below shows when an application is considered Long Line.

13. Thermostatic Expansion Valve (TXV)
A modulating flow−control valve which meters refrigerant liquid
flow rate into the evaporator in response to the superheat of the
refrigerant gas leaving the evaporator.
Kit includes valve, adapter tubes, and external equalizer tube.
Hard shut off types are available.
NOTE: When using a hard shut off TXV with single phase
reciprocating compressors, a Compressor Start Assist Capacitor
and Relay is required.
Usage Guideline:

* Ratings are net values reflecting the effects of circulating fan heat. Supplemental electric heat is not included. Ratings are based on:
EER — Energy Efficiency Ratio
SEER — Seasonal Energy Efficiency Ratio
TDR — Time-Delay Relay. In most cases, only 1 method should be used to achieve TDR function. Using more than 1 method in a system may cause
degradation in performance. Use either the accessory Time-Delay Relay KAATD0101TDR or a furnace equipped with TDR. Most Carrier 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.
