Installing The Refrigerator - Norcold N145 Owners Manual And Installation Manual

Always make sure that the ventilation gratings can never be
blocked. Blocked gratings reduce the supply and extraction
of air. An insuffi cient air supply can result in incomplete
combustion and the forming of carbon monoxide. Insuffi cient
air extraction can also reduce the refrigerator's cooling
performance.
FIGURE 2: The perfect installation situations occur when the
outside vents cannot be covered by e.g. doors.
FIGURE 3: When the refrigerator is installed next to the
caravan or motor home entry, it is imperative that the door,
when open, does not block the ventilation gratings. Allow
at least a 25 mm / 1 inch distance between the ventilation
gratings and the door.
FIGURE 4: In this situation, combustion gases may enter
the living area. Such installation situations are thus not
recommended.
4 VENTILATION
Perfect ventilation is very important to ensure the cooling
system works properly. Heat is generated in the cooling
EN
system. The heat must be able to escape into the open air.
Cold air extraction is necessary to allow the cooling system
to cool down again and to maintain the circulation of air.
FIGURE 5: The refrigerator is ventilated by means of two
openings in the wall of the caravan or motor home across
which ventilation gratings are placed. Cold air comes in
through the lower grating. The cooling system heats the cold
air and it takes out again through the upper grating (chimney
effect).
4.1 Installation ventilation gratings
- Install the ventilation gratings exactly as described in this
manual. Any other method of installation will invalidate
the manufacturer's warranty for the refrigerator.
- Always fi t the ventilation gratings at the rear of the
refrigerator. Fitting them at the side will reduce the
refrigerator's cooling capacity.
FIGURE 6: The lower ventilation grating
The lower ventilation grating should preferably be positioned
behind the burner box and the power board. This grating
is also used for access during periodical maintenance and
repairs to the refrigerator.
At the bottom of the combustion area there must be a hole in
the fl oor. If a gasleak occurs this hole will allow gas (which
is heavier than air) to stream outside instead of building up
on the fl oor (situation 1). For this purpose there should be a
hole in the fl oor which leads directly outside, with a diameter
in conformity with local regulations, but we advise a diameter
of at least Ø40 mm / 1.57 inch.
If it is not possible to make a hole in the bottom, it is
possible to position the lower ventilation grating at fl oor
level or just below (situation 2). In this way the gas has
the possibility to escape through the grating. However this
means that the refrigerator will have to be removed from the
vehicle in case of maintenance or repair of the burner box or
powerboard.
FIGURE 7: The upper ventilation grating
The installation of the upper ventilation grating infl uences
the cooling capacity. The best result is achieved when this
grating is installed as far above the condenser as possible.
For small vents use at least 110 mm / 4.33 inch (and for
large vents at least 175 mm / 6.9 inch) distance between the
top of the refrigeration cabinet and the top of the ventilation
cut-out. Situation [1] is the preferred installation procedure
for small vents and creates there the optimal cooling
capacity. Situation [3] is the preferred installation procedure
for large vents and creates there the optimal cooling capacity.
Situation [2] is without a ventilation grating at the topside of
the fridge, but with a chimney on the roof, which is also
a possibility.
4.2 Installation ventilation gratings
FIGURE 8: A ventilation system compromises of two sets of
a vent frame [A] and a vent outer [C]. To install the ventilation
gratings, make, using the templates provided, a horizontal
rectangular recess in the wall of the caravan or motor home.
1. Use the accompanying template to cut out the ventilation
recess.
2. Seal the vent frame [A] in a watertight way by means of
sealant or butyl tape.
3. Only for the upper ventilation grating with small vents:
assemble the vent cap [E] together with the vent frame
4. Position the vent frame [A] in place.
5. Place the vent outer [C] over the vent frame [A] and
fasten it with the two retaining slides [D].
5 EXTRACTION OF COMBUSTION
GASES
- The air for the burner must not come from the living area
of the caravan or motor home and combustion gases
must not enter the living area. The refrigerator must
therefore be installed in a place completely separated
(insulated) from the living area of the caravan or motor
home.
- The fully installed refrigerator must allow the proper and
complete discharge of combustion gases. Combustion
gases may contain carbon monoxide. Inhalation of this
gas may cause tightness of the chest, dizziness and can
lead to death.
- The refrigerator is designed for powering by liquid
propane gas.
- A qualifi ed person must install gas components.
- The gas components must be installed in accordance
with the latest technical regulations.
- Combustion gases must always be discharged upwards.
- The exhaust of the refrigerator must be installed so that it
is always accessible for maintenance and repairs.

6 INSTALLING THE REFRIGERATOR

- The air from the burner must not come from the living
area of the caravan or motor home and combustion
gases must not enter the living area . The refrigerator
must be installed in a place completely separated
