Service manual

MECHANICAL

Remove front grille and check refrigeration lines to see that they are free (not touching each other or compressor). Spin

condenser fan blade to see that it is free.

Check that all service valves are open. The compressor springs are secured for shipping by either tightening bolts or

shipping strap. Remove the strap or loosen the hold-down bolts so that the compressor floats freely. If the compressor

is hermetic, it is internally spring mounted and ready to run. See figures below to determine if your compressor is

hermetic (Figure 1).

ELECTRICAL

WARNING

Before servicing electrical components in the case or the doors or door frames make sure all power to case is

off. Always use a qualified technician.

Check voltage and amps drawn to determine proper line and fuse or circuit breaker size. Check power supply for low

voltage. If voltage reads “230” with no load, and it drops below “207” when the compressor tries to start, it is an indication

of too small supply wiring or too long to run.

It is recommended that a separate circuit be run for each cabinet to prevent another appliance blowing the fuse

or breaker, causing loss of product.
