To complete the installation adjust the
louver
position to 30° from plumb, this is recom
-
mended for “optimum” system performance.
NOTE:
All wiring should be in accordance
with the National Electrical Code (NEC) and
the local building codes.
1.
Make sure power is off.
2. Inspect the existing wiring for any de
-
ficiencies such as cut or frayed wires.
Replace if any such wiring if found.
T
he standard unit voltage is 208/230V
(60Hz, 1Ph). Check the unit’s rating plate
for your models’ electrical requirements.
• The wires should be capable of carry
-
ing the maximum load current under
non-fault conditions at the stipulated
voltages.
• Avoid large voltage drops on cable runs,
particularly in low voltage wiring.
• The correct cable size must be used to
ensure a voltage drop of less than 1
V
olt in the control wiring.
• Once the refrigeration pipe work is
complete, the electrical supply can be
connected.
• Low volt wiring must be at least 18
AWg.

CASSETTE AIR HANdLER INSTALLATION INSTRUCTIONS
a) Ensure that the polarized (10 posi
-
tion) connector is in the proper orien
-
tation and connected.
6. The fascia can now be tightened up
to the Cassette chassis. M
ake sure a
good seal is obtained between fas-
cia and chassis, this is necessary to
prevent recirculation.
NOTE:
Do not over
tighten the bolts. To do so
may cause damage to the
fascia and drain pan.
With filter(s) in place,
the inlet grille(s) can
now be installed onto the
fascia.
b) Route the wires in a way that ensures
that they won’t become trapped, cut,
broken, or chaffed.
