7.2 CHARGING BY WEIGHT
7.3 FINAL LEAK TESTING
After the unit has been properly evacuated and charged, a halogen leak detector
should be used to detect leaks in the system. All piping within the condensing unit,
evaporator, and interconnecting tubing should be checked for leaks. If a leak is
detected, the refrigerant should be recovered before repairing the leak. The Clean Air
Act prohibits releasing refrigerant into the atmosphere.
For a new installation,evacuation of interconnecting tubing and indoor coil is adequate;
otherwise
,evacuate the entire system. The factory refrigerant charge in the outdoor
unit is sufficient for 15 feet of standard size interconnecting liquid line. Calculate
actual charge required with installed liquid line size and length,please see 4.1 of
instruction.
With an accurate scale (+/- 1 oz.) adjust charge difference between that shown on
the unit data plate and that calculated for the new system Installation. if the entire
system has been evacuated, add the total calculated charge.
5. Compare the measured LIQUID LINE PRESSURE to the TARGET LIQUID
PRESSURE, add charge to raise the pressure or recover charge to lower it.
6. After running unit for 20 minutes if the SUCTION LINE PRESSURE changes, go
back to step 2 otherwise remove test equipment and cover the valves.
