The appliance is powered by Nominal DC 12V and must be supplied
at SAFETY EXTRA-LOW VOLTAGE circuit, a listed power converter that
conforms to UL 458 and/or C22.2 No. 107.1 is required.
Circuit Wiring Based on Voltage Drop:
Circuit wiring, gauge (AWG), length, and routing is to be determined by
the installer. It must not exceed a voltage drop at the appliance of more
than .4V DC.
To Measure:
Start the appliance from warm, isolate and measure
the voltage difference between each DC12V power source(s) and the
appliance connection. If the Voltage drop exceeds .4V DC, the length of
wire should be shortened, and/or Wire gauge (AWG) increased.
Circuit Rating:
Min 15Amp, Max 40Amp. Do not share circuit with any
other utilization equipment.
NOTE:
The circuit must be fused appropriately for the wire gauge (AWG)
used, within 18" of the DC 12V power source.
Only a single blow fuse or manual resettable breaker is allowed, auto-
resetting breakers must not be used. Do not add an additional fuse to
the pigtail end of the appliance.
The following is a starting guideline for wire sizing and should be
adjusted based on actual voltage drop:
●
Max 20ft = 10AWG
●
Max 35ft = 8AWG
●
Max 55ft = 6AWG
Installation TIPS:
●
Voltage drop can be reduced by terminating the -12V (white) lead
directly to the vehicle chassis.
●
-12V (white) and Ground (Green) leads can be combined at the
appliance or individually terminated.
Supply Wire
Pigtail Harness
from Refrigerator
Not Provided
●
Enter supply wire into the cabinet space. It is acceptable to enter
through the cabinet floor, sidewall, backwall or ceiling. Ensure that
the wire enters within the free cabinet space behind the refrigerator.
●
Girard recommends dropping the 12V supply wire from the upper
ceiling or upper rear wall. Temporarily affix the wires to the upper
half of the appliance with tape so that excess wire will droop
without risk of rubbing with the appliance chassis and floor during
installation.
Drainage Preparation
The cavity condensate drainage is captured in a drain pan integrated
with the unit. No external drainage needs to be prepared at this point.
Securing the Refrigerator
1. Center the appliance in the cabinet and adjust to align the trim
evenly to cover gaps. If the trim is uneven or protruding from the
cabinet face, ensure the cabinet base is level and add shims to align.
Do not force the appliance chassis into position as this will tweak it
out of shape.
2. Affix the refrigerator to the cabinet using the appropriate screws for
the material (Fig 1 & 2). Ensure that the screw affixes into a soft or
hardwood substrate for support. Mounting only into MDF material is
not sufficient.
NOTE:
If securing a refrigerator in a cabinet with a sidewall vent, no
additional mounting or sealing is necessary on the rear of the appliance.
