Refrigeration Installation

FP2 Sensor Installation

An FP2 sensor with violet wiring is shipped loose with the 
compressor section.  This is the air coil low temperature 
protection sensor.  Install this sensor on the refrigerant line 
between the indoor expansion valve and the air coil using 
thermal compound and the supplied mounting clips.  Ensure 
that the sensor makes good thermal contact with the refrigerant 
line and insulate the sensor.

Air coil low temperature protection will not be active if this 
sensor is installed incorrectly or is not installed.

Add-On Heat Pump Applications

The indoor coil should be located in the supply side of 
the furnace to avoid condensation damage to the furnace 
heat exchanger for add-on heat pump applications. A high 
temperature limit switch should be installed as shown in 
Figure 11b just upstream of the coil to de-energize the 
compressor any time the furnace is energized to avoid 
blowing hot air directly into the coil, elevating refrigerant 
pressures during operation. The heat pump will trip out on 
high pressure lockout without some method of disengaging 
the compressor during furnace operation. Alternatively, some 
thermostats with “dual fuel” mode will automatically de-
energize the compressor when second stage (backup) heat 
is required.

The TXV should be brazed into place as shown in Figure 10, 
keeping the “IN” side toward the compressor section. The 
TXV has an internal check valve and must be installed in the 
proper direction for operation. Always keep the valve body 
cool with a brazing shield and wet rags to prevent damage 
to the TXV. Attach the bulb to the suction line using the 
supplied hose clamp. Be careful not to overtighten the clamp 
and deform the bulb.

NOTICE!

 The air coil should be thoroughly washed with a 

fi

 lming agent, (dishwasher detergent like Cascade) to help 

condensate drainage. Apply a 20 to 1 solution of detergent 
and water. Spray both sides of coil, repeat and rinse 
thoroughly with water. 

Evacuation and Charging the Unit
LEAK TESTING -

 The refrigeration line set must be pressurized 

and checked for leaks before evacuating and charging the unit. 
To pressurize the line set, attach refrigerant gauges to the service 
ports and add an inert gas (nitrogen or dry carbon dioxide) until 
pressure reaches 60-90 psig [413-620 kPa]. Never use oxygen or 
acetylene to pressure test. Use a halogen leak tester or a good 
quality bubble solution to detect leaks on all connections made 
in the 

fi

 eld. Check the service valve ports and stem for leaks. If 

a leak is found, repair it and repeat the above steps. For safety 
reasons do not pressurize system above 150 psig [1034 kPa]. 
System is now ready for evacuation and charging.
Turn service valves full out CCW (see Table 6) and then turn 
back in one-half turn to open service ports. Add the required 
refrigerant so that the total charge calculated for the unit 
and line set is now in the system. Open the service valve 

fully counter clockwise so that the stem will backseat and 
prevent leakage through the schrader port while it is not in 
use. Start unit in the heating mode and measure superheat 
and subcooling values after 5 minutes of run time. See 
tables 14d for superheat and sub-cooling values. Superheat 
is measured using suction temperature and pressure at the 
compressor suction line. Subcooling should be measured 
using the liquid line temperature immediately outside the 
compressor section cabinet and either the liquid line service 
valve pressure or the compressor discharge pressure. Note 
that di

 erent values from tables 14d will be obtained due to 

the pressure losses through the condenser heat exchanger. 
Adding refrigerant will increase sub-cooling while superheat 
should remain fairly constant allowing for a slight amount 
of hunting in TXV systems. This increase in subcooling will 
require 5 minutes or so of operation before it should be 
measured. After values are measured, compare to the chart 
and go to “FINAL EVALUATION.”

PARTIAL CHARGE METHOD

 - Open service valve fully 

counterclockwise and then turn back in one-half turn to 
open service port. Add vaporized (Gas) into the suction side 
of the compressor until the pressure in the system reaches 
approximately 100-120 psig. Never add liquid refrigerant into 
the suction side of a compressor. Start the unit in heating 
and add gas to the suction port at a rate not to exceed 

fi

 ve pounds [2.27 kg] per minute. Keep adding refrigerant 

until the complete charge has been entered. Superheat is 
measured using suction temperature and pressure at the 
compressor suction line. Subcooling should be measured 
using the liquid line temperature immediately outside the 
compressor section cabinet and either the liquid line service 
valve pressure or the compressor discharge pressure. Note 
that di

 erent values from tables 14d will be obtained due to 

the pressure losses through the condenser heat exchanger. 
Adding refrigerant will increase sub-cooling while superheat 
should remain fairly constant allowing for a slight amount 
of hunting in TXV systems. This increase in subcooling will 
require 5 minutes or so of operation before it should be 
measured. After values are measured, compare to the chart 
and go to “FINAL EVALUATION.”

FINAL EVALUATION 

-In a split system, cooling subcooling 

values can be misleading depending on the location of the 
measurement. Therefore, it is recommended that charging 
be monitored in the heating mode. Charge should be 
evaluated by monitoring the subcooling in the heating mode. 
After initial check of heating sub-cooling, shut o

  unit and 

allow to sit 3-5 minutes until pressures equalize. Restart unit 
in the cooling mode and check the cooling superheat against 
Tables 14d. If unit runs satisfactorily, charging is complete. If 
unit does not perform to speci

fi

 cations the cooling TXV (air 

coil side) may need to be readjusted (if possible) until the 
cooling superheat values are met.
