Refrigerator Power Supply may be connected
to either AC or DC power only, if so desired.
For DC wiring, follow the same instructions as
stated in the "DC Only Wiring" section. For AC
wiring, use a 10 Amp circuit breaker maximum.
Check that all wire sizing is correct and that all
grounding systems are in good working order.
The appliance must be wired and grounded in
accordance with the ABCY Guideline E8 or
Equivalent. See ABYC Guidelines E8, page 4.
Important: Make sure that proper polarity is main-
tained at all times.

2. (Refrigerator Power Supply), 120/240 VAC & 12
VDC Convertor.
Note: On TJ18 models the Refrigerator Power Supply is
supplied loose inside the refrigerator. It will need to be
mounted in a dry location close to the refrigerator. See wir-
ing diagram for proper wiring. The Power Supply is mounted
to the rear of the cabinet on all other models.
a. If the refrigerator is equipped with a refrigera-
tor power supply, then both AC and DC power
may be used. The Power Supply functions by
converting AC power into DC power for the
compressor. When the power supply is con-
nected to both AC and DC, and the AC power
is on, then the unit will run on AC power. How-
ever, if the AC power is lost, the unit will run on
the DC power. If both types are to be used,
connect the DC wiring to the DC distribution
center, and the AC wiring to the AC distribu-
tion center, following ABYC guidelines. The
OPERATING INSTRUCTIONS
A. Rotary Thermostat
Each refrigerator is fitted with a manual thermostat. It
automatically maintains the set temperature.
1. To start the refrigerator, turn the thermostat adjust-
ment knob clock-wise. To start off with, a mid-range
setting should be selected. See FIG. 2A. Allow the
refrigerator to run at least 12 hours before loading
it with goods.
2. Once the refrigerator is cold, adjust the thermo-
stat knob to obtain the desired temperature. The
thicker the band, the colder the temperature.
3. To turn the refrigerator OFF, rotate the thermostat
adjust knob counter-clock-wise until the indicator
is pointing to OFF. See FIG. 2B

Note: The data plate bearing the model and serial number
and technical data is located inside the refrigerator on the
right-hand side of the cabinet.
1. 12/24 VDC Only Wiring
a. For direct current (DC) refrigerators, connect
the refrigerator to the DC distribution center. A
15 Amp circuit breaker must be installed for
systems using 12 VDC and a 10 Amp if the
system is 24 VDC. Check that all grounding
systems are in good working order. The Ap-
pliance must be wired and grounded in ac-
cordance with the ABYC Guideline E9 or
equivalent. See ABYC Guidelines E9 on
page 3.
