INSPECT EQUIPMENT File claim with shipping company prior to installation if shipment is damaged or incomplete. Step 2—Install on a Solid, Level Mounting Pad If conditions or local codes require the unit be attached to pad, tie down bolts should be used and fastened through knockouts provided in unit base pan.
8. Install vapor elbow (see Fig. 5B) with equalizer adapter to suction tube of line set and suction connection to indoor coil. Adapter has a 1/4-in. male connector or attaching equalizer tube. 9. Connect equalizer tube of TXV to 1/4-in. equalizer fitting on vapor line adapter.
Do not leave system open to atmosphere any longer than minimum required for installation. POE oil in compressor is extremely susceptible to moisture absorption. Always keep ends of tubing sealed during installation. If ANY refrigerant tubing is buried, provide 6–in.
5. Repeat this procedure as indicated in Fig. 9. System will then contain minimal amounts of contaminants and water vapor. FINAL TUBING CHECK IMPORTANT: Check to be certain factory tubing on both indoor and outdoor unit has not shifted during shipment.

required. The LCC for standard PSC blower products consists of a standard humidistat which opens contacts on humidity rise and a pilot duty relay with 24v coil. NOTE: If an LCC is desired, low-speed airflow must be main- tained so that a minimum of 300 CFM/ton can be supplied during high speed LCC operation.

Step 10—Start-Up To prevent compressor damage or personal injury, observe the following: • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure.
Step 11—Check Charge Service valve gage ports are not equipped with Schrader valves. To prevent personal injury, make sure gage manifold is connected to the valve gage ports before moving valves off fully back seated position. Wear safety glasses and gloves when handling refrigerant.
FACTORY DEFAULTS Factory defaults have been provided in the event of failure of outdoor air thermistor, coil thermistor, and/or furnace interface jumper. ONE MINUTE SPEED CHANGE TIME DELAY When compressor changes speeds from high to low or low to high, there is a 1-minute time delay before compressor restarts.
Compressor Control Contactors Low and high capacity contactor coils are 24 volts. The electronic control board controls the operation of the low speed (C-L) and the high speed (C-H) contactors. TEMPERATURE THERMISTORS Thermistors are electronic devices which sense temperature.
