Specifications

Use only Carlyle approved oil appropriate for the

refrigerant being used. Sections 3.6 and 3.7 on

pages 69-72 list all the approved oils. Section 3.11 on

page 73 notes the correct oil pump pressure in relation to

age of the compressor.

3. Leak test, evacuate, and dehydrate the system.

4. Charge the system. When initially charging the high side

of the system with liquid refrigerant, all service valves

should be closed (front seated). This will prevent

refrigerant from migrating to the compressor crankcase

and into the oil, causing a flooded start.

The system is now charged and ready for start-up.

Recheck the oil levels and add or remove oil as neces-

sary. Open (backseat) the discharge service valve and

any oil equalization lines on parallel systems. Open the

suction service valve 1/2 to 1 turn, or enough to allow

the compressor to run without tripping the low-pressure

switch. This is to prevent damage to the compressor

from any liquid refrigerant floodback.

5. On water-cooled condensing systems, open water supply

valve and allow water to reach condenser. On air-cooled

condensing systems, turn condenser fan on when the

compressor unit is started.

6. Ensure that all evaporator connections are opened and

fans started.

7. On systems with more than one compressor in parallel,

start one compressor at a time.
