temperature control problems.
Service and Maintenance Clearances
Make sure there are adequate clearances for future
maintenance and service. Allow enough room to access the
condensate pump assembly and the electrical control box.
Electrical Power
Follow all local codes and regulations when installing electrical
wiring.
Route required electrical power to area where the High ESP
Duct unit is to be located. Maintain at least a 10 foot
separation between TV and Radio wiring and the power to
the indoor unit.
14 Gauge AWG stranded wire should be used t
o make the
electrical connection between indoor and outdoor units.
This wiring will serve to power the indoor unit and establish a
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 connected to terminals 1 or 3 as these
serve as communication signal wires and electrical power
connections. If a safety switch needs to be in place to shut o
power to the indoor unit, break wire 2 only.
Condensate Handling
The High ESP Duct unit has a built-in condensate pump and
water level safety switch. There are also two optional ports
for gravity drainage. The condensate pump is rated to lift
water up to 24” from the point of discharge on the High ESP
Duct unit.
The High ESP Duct unit comes with a grey connection hose
with clamp. This hose is connected to the High ESP Duct unit
condensate discharge hose port. The other end of the hose
is sized to accept 3/4 inch PVC piping.
