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 on (Page 17-20) 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.
IMPORTANT
Models (2 and 3 door low temp) are pre-wired internally with a 208-230V NEMA L14-20P plug
and should only be plugged into a NEMA L14-20P recepticle. See wiring diagrams on
page 19-21. The cabinet should be grounded.
LEG AND CONDENSATE PAN INSTALLATION FOR TOP MOUNT CABINETS ONLY
1. Screw legs into existing crate mounting holes.
2. Before moving cabinet into place, remove the
condensate pan from the top unit compartment.
3. Using the two screws supplied with the pan, attach
the pan to the back of the cabinet at the two holes
near the bottom of the plastic drain line. Be sure
pan is NOT located directly under cabinet. When
the pan is attached, feeds drain line into the open
hole in screen and clamp the heater conduit to the
back of the cabinet. Due to this condensate pan,
this case must be a minimum of 6” from the wall.
4. If cabinet must be located next to wall, the pan can
be located under the cabinet. When this is done,
steam will accumulate on the bottom of the cabinet
if there is not adequate ventilation, and rusting of
the bottom of the cabinet
will occur.
