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.
NOTICE
For models with electronic ballast only:
For replacement ballast, use only ballast that complies with UL Type CC rating if unit is equipped with
electronic ballast.
Check voltage and amps drawn on (Page 12-15) to determine proper line and fuse or circuit breaker size. Check power
supply for low voltage. If voltage reads “120” with no load, and it drops below “100 or less” 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
This cabinet is pre-wired internally for 120-volt circuits. “Tapping” or feeding the 115-volt circuit from 230-volt supply
may result in overloaded circuit breakers or blown fuses and damage to electrical system, thereby voiding the warranty.
The cabinet should be grounded.
