box end of the air conditioner to allow for
the installation of both the low and high
voltage wiring.
7)
Insure that neither the vehicle engine
exhaust, on-board generator engine exhaust
or water heater vent exhaust are pulled into
the condenser’s cooling air flow. These hot
gases will both: (a) increase system
temperature reducing performance and
equipment life; and (b) the collection of
these gases chemical by-products will begin
the chemical degradation of the surfaces
they collect on.
In order to improve installation time and reduce down time
when servicing, RV Products recommends using drawer
slides for mounting the air conditioner.
This unit must be supported from below by angle iron,
channels or RV frame members. These supports must be
located under the air conditioner and kept within the areas
shown (cross-hatched) in Figure 2. Support must be provided
in the areas indicated to both secure the compressor and
balance the system. Adding support outside of the indicated
area may interfere with either the condenser air outlet or the
condensate drain.
When suspending the unit from flooring or frame members, a
minimum of four threaded rods are required. Minimum rod
diameter is 5/16". The support rods and hardware must be
plated or equivalently protected against corrosion. All
threaded fasteners should be provided with lock washers,
“locktite”, “double-nutted”, or equivalently protected from
vibration loosening after installation.
Air conditioner condensation may at times splash out of the
drain pan and drain from the unit corners. Therefore, do not
mount the air conditioner above areas which might be
damaged by exposure to moisture.
Upon completion of the installation, verify that the air
conditioner has a minimum clearance of 14" from the bottom
of the air conditioner to ground level.
7. DUCT MOUNTING AND CONFIGURATION
This system is designed for the back of the air conditioner to
seal to the vehicle. The ducting for the air conditioner
attaches and seals to the side. Cut-outs in the flooring
provide passage for both the cold supply air and the warm
return air.
The preferred mounting configuration is the end outlet-side
return configuration. Reference Figure 1. This system ducts
the cold supply air out the end of the air conditioner while the
warm return air is drawn in through the side of the air
conditioner. With this configuration, one cut out will be
required to match the end opening in the air conditioner and
another to match the back opening.
Under no circumstances will either of the openings or
associated ducting be allowed to have a misaligned or smaller
inner perimeter than either air conditioner opening.
DANGER - SHOCK HAZARD
Do not drill any openings into this air
conditioner. Use only the pilot holes
already provided. Drilling new openings
and inserting screws may damage either
the refrigeration circuit or electrical
wiring causing possible equipment
damage, personal injury or death.
To provide both vibration dampening for the unit and air
tight seals for both supply and return air openings, RV
Products recommends the use of foam gaskets.
Gaskets do not come with the air conditioner, they must be
provided by the installer. This allows the installer the option
of either providing their own gaskets or not using gaskets and
attach ducting directly to the air conditioner.
Attaching ducting directly to the air conditioner is not
recommended unless the installer can provide a means for
access and quick disconnect. Generally an installation of this
type will require vehicle disassembly before some types of air
conditioner repair can be completed.
IMPORTANT
Regardless of installation configuration,
ensure that both duct connections are
air tight. Loose or leaking connections
can reduce system performance and
allow gases, odors and dirt to be drawn
in from outside the vehicle.
