System Start Up and Charge Adjustment Procedures

Leakage check

Properly check refrigeration tubes and connections for any leaks prior to system start up procedures.

NOTE:

A is the low-pressure valve B is the high-pressure valve

C and D are the joints of connecting pipes of indoor unit.

Air exhaust

The outdoor unit is supplied with a R-22 charge sufficient for 15 feet of refrigeration tubing. The outdoor unit’s liquid and suction valves are closed to contain the charge within the unit. The recommended procedures for charge adjustments are as follows:

Additional Charge Needed for Refrigeration lines over 15 feet

Liquid Line O.D. (Inches)

Additional R-22 (oz / ft)

1/4

.22

3/8

.58

1.After connecting the refrigeration tubing to the indoor and outdoor units. connect a vacuum pump to the refrigeration valve service ports.

2.Evacuate through the liquid and suction valve service ports to 500 microns or less for a minimum of 30 minutes. Close the valves to the pump and monitor the vacuum for 15 minutes. The vacuum should not rise above 800 microns.

3.If a vacuum of 500 microns cannot be obtained, or if it rises ablve 800 microns over the 15 minute period, discontinue evacuation, pressurize the system with nitrogen and look for leaks. Repair any leaks that are found and repeat step 2.

4.Close the valves to the vacuum pump, turn the pump off, and disconnect it from the refrigerant valve service ports. Open the liquid and suction service valves fully, releasing the R-22 into the system. Connect the service gauges to the refrigerant valve service ports.

5.Set the indoor remote control to cool mode and ensure proper operation. Allow unit to run for a period of 10 minutes to allow system pressures to stabilize.

*Make sure that proper pressures are observed.

*Check proper temperatures in space, to ensure temperatures match those on remote control.

*Check condensate drain hose for proper drainage.

*Check for any abnormal vibration noises and correct as needed.

*Check for any signs of refrigerant leakage.

6.Set the indoor remote control to heat mode and ensure proper operation. Allow unit to run for a period of 10 minutes to allow system pressures to stabilize. Fllow same checkouts as cool mode.
