Unit installation

The thermostat 9 pin receptacle mates with a receptacle on one
end of the RV Products 35' pre-wired thermostat harness. See
component match-up section for harness part number and
description.
The thermostat harness does not include the wiring for the 3-
pin plug. Should the installer desire a total plug in system,
then the mate and pins for this connection must be purchased
separately. Both the receptacle and the pins are manufactured
by AMP (Aircraft Marine Products, Inc., Harrisburg, PA). In
most cases the parts can be obtained through a local supply
house.
The AMP part numbers are:
1) 3 pin male receptacle #7-480700-0
2) female pin (for male receptacle) #350218-1
Should the installer desire to hard wire this connection rather
than purchasing the receptacle, the three pin connector can be
cut from the wire ends, the wires stripped and spliced to
complete the required connections. For further wire
identification and function, reference Chart 2.

IMPORTANT
When using wire nuts to complete electrical connections,
always apply a U.L. approved electricians tape and secure the
wire nuts to the wires in a workmanlike manner.
THERMOSTAT HARNESS
RV Products produces a pre-wired 35' thermostat wiring
harness for this system. See component match-up section for
harness part number and description. This harness consists of
the wires required for operating the heat pump and quick
connect receptacles for both the thermostat and the heat pump
connections.
At the thermostat, the connection is completed with a square 9
pin receptacle that slides together and snap-locks in place.
When making this connection:
1) verify that the connectors are properly
aligned
2) do not use excessive force when joining the
connectors
3) verify that the connectors have snapped
together on both sides.
The thermostat umbilical attaches to the unit with a rain-tight
fitting. To install, remove the ring-nut from the rain-tight
fitting and insert the wire end and fitting into the hole in the
wirebox side. The ring-nut will now slide over the wire end
and reinstall onto the rain-tight fitting threads. Tighten
securely. The wire end plugs into the receptacle on the
wirebox printed circuit board. Insure that the plug “snap-
locks” into the receptacle.
Routing of the thermostat wiring harness must comply with all
local and national electrical codes. Collect any excess
thermostat harness in the heat pump mounting compartment.
Be sure to secure the excess wiring within the compartment.
Coiling the excess harness into 3" diameter circles or larger is
acceptable.
THERMOSTAT MOUNTING
Follow the instructions packed with the thermostat to select a
location for thermostat mounting. Pay particular attention to
choose a location which is not totally isolated from air currents
and is not subject to direct discharge from an air register.
