Installation and Owner’s Manual 12
Assemble the Enclosure
1. Make sure the enclosure is 20.81 - 20.87 inches high x 19.38
- 19.44 inches wide x 24.38 inches deep.
2. Make sure the floor is solid and level.
- The floor must be metal or a wood panel and extend the full
width and depth of the enclosure.
- The floor must be able to support the weight of the refrigera-
tor and its contents.
3. Make sure there are no adjacent heat sources such as a
furnace vent, a hot water heater vent, etc.
4. If there is more than 1/2 inch between either side of the
refrigerator and the inside of the enclosure:
- Fill the space with fiberglass (batt-type) insulation or add a
baffle to eliminate the clearance.
- The rear of the batt-type insulation must be between 18
-19 inches from the face of the enclosure.
- Securely attach the batt-type insulation to the enclo-
sure, so that it remains in this position during refrigera-
tor installation, if it becomes wet, and in windy condi-
tions.
Install the Lower and Upper Vents
1. Determine the rough opening (RO) size for each vent.
Certified Vent Part No. RO Height RO Width
Upper Side 617485 7 1/4 in. 18 in.
Exhaust Vent
Lower Side 617484 9 3/4 in. 19 3/8 in.
Intake Vent
2. Install the lower intake vent (See Art01634):
NOTE: The lower intake vent is also the service access
opening for the components on the rear of the refrig-
erator.
Reverse the Door Swing (optional)
This refrigerator has door hinges that allow you to change the
direction that the door opens by moving the hinges on a
diagonal to the opposite side. (See Art01031)
1. Remove the door:
- Remove the storage bins from the door.
- Turn out and save the upper hinge pin [1].
- Open the door a small amount and pull the top of the door
away from the upper hinge of the refrigerator.
- Lift the door off [2] of the lower hinge pin [3].
- Turn out and save the lower hinge pin.
These clearances plus the lower and upper vents cause the
natural air draft that is necessary for good refrigeration. Cooler
air goes in through the lower intake vent, goes around the
refrigerator coils where it removes the excess heat from the
refrigerator components, and goes out through the upper
exhaust vent. If this air flow is blocked or decreased, the
refrigerator may not cool correctly.
Each NORCOLD model is certified by CSA International for
correct ventilation. Install only the certified vents that are listed
in this manual.
WARNING: Make sure the bottom of the opening for the
lower intake vent is even with or immediately below the
floor level. This allows any leaking propane gas to
escape to the outside and not to collect at floor level.
- Make sure the bottom of the opening of the lower intake vent
[1] is even with or immediately below the floor level.
- Align the lower intake vent vertically below the coils [2] and
the condenser [3] of the refrigerator.
3. Install the upper exhaust vent (See Art01635):
- Make sure the distance [4] from the floor level to the top of
the rough opening for the upper exhaust vent is at least 20
5/8 inches or poor cooling performance can occur.
- Align the upper exhaust vent [5] horizontally above the
lower intake vent [1] of the refrigerator.
- For the best cooling performance and if the construction of
the vehicle allows, the distance [4] from the floor level to the
top of the rough opening of the upper exhaust vent [5]
should be as near 30 1/2 inches as possible.
- Align the upper exhaust vent [5] horizontally above the
lower intake vent [1] of the refrigerator.
- Install a baffle [6] to prevent stagnant hot air in the area
[7] above the refrigerator.
- Make sure there is less than 1/4 inch clearance [8]
between the baffle and the top of the refrigerator.
- Make sure the baffle is the full width of the inside of
the enclosure.
- If the distance from the back of the refrigerator to the wall of
the vehicle is more than one inch, install a baffle [9] at the
top of the intake vent between the back of the refrigerator
and the wall of the vehicle.
