3.Measure and record the suction pressure at the suction service valve port.

4.Using Table 4, note the superheat value corresponding to the intersection of the indoor wet bulb and the outdoor dry bulb.

5.With the superheat value obtained in step 4 and the suc- tion pressure value from step 3, find the intersection of the values in Table 5. This is the required suction tube temperature at the suction service valve.

6.To bring the tube temperature in line with the required value from Table 5, add refrigerant to the service port to cause the tube temperature to fall and reclaim refrigerant to cause the temperature to rise.

CHECKOUT PROCEDURE

Use the following list to see that nothing was over looked:

1.Have all braze joints on refrigerant lines been leak checked? (Sweat Fit Units)

2.Line set fittings leak checked? (Quick Connect Units)

3.Have base valves been opened? (Sweat Fit Units only)

4.Have all refrigerant lines been secured and isolated properly?

5.Is the indoor coil drain hooked up and draining freely? Pour water in drain pan.

6.Is air filter installed and clean?

7.Is the blower motor speed set correctly?

IMPORTANT - Installer should place unit data sheet and installation instructions in customer packet and give to home owner after installation is complete.

SYSTEM OPERATION CHECKOUT

1.With thermostat set to the OFF position, close discon- nect switch or switches to complete circuits to condens- ing unit and furnace. Set thermostat to call for cooling.

2.After the system starts, check the voltage and amperage at the condensing unit contactor.

3.If voltage is not within 10% of rated voltage, or amperage greatly exceeds nameplate amperage, shut down the system and contact the local power company for correc- tions; otherwise unsatisfactory performance may result.

4.With the system in operation, check the condensing unit for unusual noise and undue vibration.

5.Allow the system to operate until it is balanced or stabi- lized (approximately 30 minutes), before making further checks.

6.Remove manifold gages hoses, and install cap on Schrader valves.
