If a compressor does not start:
1. IMPORTANT! The room conditions must be approximately as shown on the unit nameplate.
2. Check that the software compressor enable is actually set to AUTO.
3. Check that the compressor-overload device (if any) is ON.
4. Check STATUS MESSAGES (next page) to be sure that
4a. the blower is ON, and
4b. the Firestat is in the normal condition.
5. Correct the above as necessary.
If the compressor still does not start, temporarily change the set points (third page following) to cause it to do so.
NOTE: Air-compartment access doors or panels must
remain closed while the compressor(s) is running, except
briefly for expansion-valve adjustment.
NOTE: The evaporator pressure may not be stable for a few minutes. This is normal.
If instability persists, it should be corrected when the expansion valve is adjusted
(see following instructions).
