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.
14/4 non-shielded stranded copper cable 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 wires 1, 3, and Ground
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.
NOTE:
Strain relief must be installed.
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.
