*Compressor listed is the standard compressor for R-22, air conditioning duty. An 06ER compressor is standard equipment
for low temperature (R-507/404A) applications. For medium temperature (R-134a) applications, an 06EM compressor is
standard. Factory substitutions may be made. Contact Carrier Sales Representative.
†The condenser listed is for R-22, air conditioning duty and may change based on the application. Maximum condenser
operating pressure: 350 psi refrigerant side, 150 psi water side.

START-UP

Energize crankcase heater at least 24 hours prior to start-up.
Check to see that oil level is approximately
compressor sight glass.
Open water supply valve and allow water to reach condens-
er. (Turn condenser fan on when the compressor unit is applied
with air-cooled condenser.)
Backseat the compressor suction and discharge shutoff
valves; open liquid line valve at receiver.
Start evaporator fan or chilled water pump.
Do not attempt start-up with terminal cover removed from
compressor. Bodily injury or death may result from
explosion and/or fire if power is supplied to compressor
with the terminal cover removed or unsecured. See
warning label on terminal cover.
Start Compressor —
Push the control circuit START-
STOP-RESET switch to START. The timer motor starts
immediately. Depending on the position of the timer, the
compressor start is delayed for 12 seconds to approximately
8 minutes. Check oil pressure after compressor has run a few
minutes; the pressure should be 12 to 18 psi above the suction
pressure. After about 20 minutes of operation, stop the com-
pressor. Allow it to be idle for about 5 minutes, then observe
the oil level in the sight glass. Refer to the Carrier Standard
Service Techniques Manual, Chapter 1, Section 1-11, for
adding oil. The proper oil level for the 06E compressor is
1
approximately / up on sight glass.
