Step 9: Wiring the Unit
All electrical wiring/connections shall be performed
by a licensed and certified technician and electrician.
Warranty will be void if proper wiring practices are
not followed.
All electrical and control wiring must be installed in
accordance with the codes listed in Section 1 of this
manual. Standard wiring diagram is provided in Figure
2.33. Optional wiring diagrams are provided in Figures
2.34 - 2.37. A separate 230/60/1 power supply is
recommended for the unit.
When sizing for proper circuit
breakers and wire size to supply the air handlers,
all local and national electrical codes must be fol-
lowed. The MCA and MOP are provided on the
nameplate of each air handler as well as in this
manual for reference. Failure to follow electrical
codes will resule in void of warranty.
Connect power supply to Terminals L1 and L2 on the
high voltage terminal block. Connect a ground wire to
the equipment ground terminal located next to the high
voltage terminal block.
Locate the room thermostat on a wall near the return air
box. Install the selected thermostat per the thermostat
manufacturer's installation instructions. Ensure the
proper wiring from the thermostat to the SpacePak air
handler by following the air handler diagrams found in
this manual.
Turn off electrical power supply
before servicing. Contact with live electric com-
ponents can cause shock or death.
