GE Ceiling Cassette Installation Manual

8 31-5000098 Rev. 1
Installation Instructions: Introduction and Overview
Condensate Handling
The Cassette unit has a built in condensate pump
and water level safety switch. There is no option for
gravity drain. The condensate pump is rated to lift
water up to 47 3/16” from the point of discharge on
the cassette assembly.
The cassette unit comes with a grey connection
hose with clamp. This hose is connected to the
cassette assembly discharge hose port. The other
end of the hose is sized to accept 3/4 “ PVC piping.
Recommended condensate piping configurations are
shown here:
Electrical Power
Follow all local codes and regulations when installing
electrical wiring.
Route required electrical power to area where the
Cassette unit is to be located. Maintain at least
a 10 foot separation between TV, Radio or any
communication wiring and the power to the indoor
unit.
14 Gauge stranded copper wire should be used to
make the electrical connection and communication
link between indoor and outdoor units.
The wiring is connected at the indoor unit electrical
terminal blocks screws 1, 2, 3 and ground. There
should be no splices in the wires between the indoor
and outdoor units as these serve as communication
signal wires and electrical power connections. Any
accessory added to shut off power to the indoor
section should break the Number 2 terminal only.
Air Delivery Clearances
Make certain to maintain proper clearances
around the cassette as specified in the installation
instructions. Standard clearances for cassette air
handlers require 5 feet of clearance in each direction.
There should be 8 feet of clearance from the face of
the cassette grille to the floor. Inadequate clearances
can cause system freezing and temperature control
problems.
Fresh Air Intake Option
The cassette has a marked area to cut out if outside
air is desired. The piping connection should be made
with a 4 inch diameter pipe. Outside air should be
pre-filtered prior to entry into the cassette.
