Suction Line Size by Length ("ODS)

Evacuation, Leak Detection, and Charging
Once the piping is installed, the following steps should be performed to ensure a
dry and leak-free system:

1. The Condensing unit is pre-charged with compressor oil. To avoid moisture

contamination of the oil, do not leave the service valves open to atmosphere
for more than 15 minutes.

2. Open the liquid and suction service valves on the condensing unit.

3. a. Dual Power Source / Valve Control: Supply power to the Evaporator only

- DO NOT connect power to the Condensing unit. Turn on the
temperature controller, which will energize and open the liquid line
solenoid valve. Verify the solenoid is powered as indicated by the
compressor icon ("snowflake") on the temperature controller display.
