The 6636 series package air conditioners are intended only
for installation by RV manufacturers. The units are for "off
the roof" installations and will usually be installed under the
floor of the vehicle. It is understood that the vehicle
manufacturer has provided an installation area which allows
for floor cutouts and unit mounting without cutting vital
frame members or electrical wiring and that structural
members in the installation area will not create restrictions by
passing through airways required by the air conditioner.
Conditioned air is delivered from the air conditioner to the
interior of the vehicle through ducting that is supplied and
installed by the vehicle manufacturer. The system return air
duct, return air filter and filter retainer are also supplied by
the vehicle manufacturer.
The air conditioner draws in outside air to cool what is
referred to as the condensing coil. The air that is drawn
across the condensing coil is referred to as the condensing air
flow.
The installer is responsible for the proper ducting and routing
of the condensing air flow.
The condensing air flow is drawn in through the side of the
air conditioner (across the condensing coil), and discharged
out through the bottom of the appliance (through the
discharge opening). Figures 1 and 2 show the location of
both the air conditioner's condensing coil and discharge air
opening.
The air conditioner must be installed so that the side that
houses both the condensing coil and the electrical box, faces
towards the outer skin of the vehicle. The air conditioner is
installed this way so that:
1)
the condensing air flow will be drawn in
from the outdoors through the side of the
vehicle; and
2)
the air conditioner can be serviced
electrically.
To provide adequate condensing air flow, the installer must
adhere to the following guidelines:
1)
Install the air conditioner so that the
condensing coil faces the outer skin of the
vehicle; and

The air conditioner is powered by two separate 115 volt
20 AMP electrical services.
The air conditioner is controlled by a 12 VDC electronic wall
mounted thermostat. The vehicle manufacturer must provide
the power source for the thermostat.
Avoid sliding the air conditioner without the shipping block
being attached. The air conditioner's condensate drain fitting
extends slightly below the pan and will be damaged if not
protected.
2)
The outdoor air path to the condensing coil
should be as direct and non-restrictive as
possible. RV Products recommends placing
the exterior condenser air flow grille into
the side of the vehicle, directly in front of
the air conditioner's condensing coil. The
installer must provide the exterior
condenser air opening and/or grille.
3)
Any decorative grille or louver used as an
opening for condenser air flow must have
410 square inches of free area.
4)
Do not block or restrict the discharge air
opening (located in the bottom of the air
conditioner) with any flooring or bracing.
5)
The air that is being used to cool the
condensing coil cannot be drawn from the
underside of the vehicle. Seal or baffle the
sides and bottom edge of the air conditioner
to prevent the recirculation of hot air from
underneath the vehicle. Recirculation of
hot air across the condensing coil will
decrease both system performance and
equipment life.
6)
Do not install any other heat generating
appliance in the same cavity as the air
conditioner. Additional heat in this cavity
will decrease system performance and
equipment life. Overall package
dimensions are shown in Figure 1. RV
Products requires that a minimum of 4
additional inches be allowed at the wiring
