Main Electrical Power
Requirements
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with an appropriate
voltmeter that all capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. 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.
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
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.
An evaporator condensate drain connection is provided
on each unit. Refer to
and
for the appropriate drain location.
The condensate drain pan is factory installed to drain
condensate to the back side of the unit. See
and
. 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.
2. Remove the support panel that the condensate drain
pan exits through.
3. Slide the condensate drain pan out of the unit and
rotate 180°.
4. Slide the condensate drain pan back into the unit, align
the drain with the grommeted opening in the rear
support panel and push until the coupling is seated in
the grommet.
5. Replace the front support panel by aligning the panel
with tabs in the raceway. Align the condensate drain
pan support in the grommeted hole as the panel is put
in place.
6. Replace evaporator access panel and supply air access
panels.
To convert drain condensate through the base of unit:
1. Remove evaporator access panel and supply air access
panels.
2. Remove the support panel that the condensate drain
pan exits through.
3. Slide the condensate drain pan out of the unit.
4. Place on a level surface in the position it was removed
from the unit.
5. Remove the plug knockout in the bottom of the
drainpan to convert it to through the base drainage.
6. Plug the original condensate drain opening with a field
supplied 3/4” NPT plug.
7. Slide the condensate drain pan back into the unit, align
the drain support with the grommeted opening in the
rear support panel and push until the support is seated
in the grommet.
