Installation
WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.
Failure to follow this instructions could result in death or
serious injuries.
Verify that the power supply complies with the unit
nameplate specifications.
• Inspect all control panel components; tighten any
loose connections.
• Connect properly sized and protected power supply
wiring to a field-supplied/installed disconnect switch
and to the main power terminal block (HTB1) in the unit
control panel.
• Install proper grounding wires to an earth ground.

Electric Heat Requirements

• Verify that the power supply complies with the electric
heater specifications on the unit and heater nameplate.
• Inspect the heater junction box and control panel;
tighten any loose connections.
• Check electric heat circuits for continuity.
Low Voltage Wiring
(AC & DC) Requirements
• Install the zone thermostat, with or without switching
subbase.
• Connect properly sized control wiring to the proper
termination points between the zone thermostat and
the unit control panel.

Condensate Drain Configuration

An evaporator condensate drain connection is provided
on each unit. Refer to Figure 16, p. 23
for the appropriate drain location.
The condensate drain pan is factory installed to drain
condensate to the back side of the unit. See
and Figure 17, p. 24. It can be converted to drain
condensate out the front side of the unit or through the
base.
To convert drain condensate out the front of unit:
1. Remove evaporator access panel and supply air access
panels.

9. Replace evaporator access panel and supply air access
A condensate trap must be installed at the unit due to the
drain connection being on the "negative pressure" side of
the fan. Install the P-Trap using the guidelines in
p.
and Figure 17, p. 24
A condensate drain line must be connected to the P-Trap.
Pitch the drain lines at least 1/2 inch for every 10 feet of
horizontal run to assure proper condensate flow. Do not
