SERVICING

Checking Voltage

High Voltage!
Disconnect all power before servicing or
installing. Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
1. Remove doors, control panel cover, etc. from unit being
tested.
With power ON:
Line voltage now present
2. Using a voltmeter, measure the voltage across terminals
L1 and L2 of the contactor for single phase units, and
L3, for 3 phase units.
3. No reading - indicates open wiring, open fuse(s) no
power or etc. from unit to fused disconnect service.
Repair as needed.
4. If incoming voltage is within the range listed in the chart
below, energize the unit.
5. Using a voltmeter, measure the voltage with the unit
starting and operating to determine if voltage is within
the range listed in the chart below.
6. If the voltage falls below the minimum voltage, check
the line wire size. Long runs of undersized wire can
cause low voltage. If the wire size is adequate, notify
the local power company regarding either low or high
voltage.

208/230
NOTE: When operating electric heaters on voltages
other than 240 volts, refer to the System Operation
section on electric heaters to calculate temperature
rise and air flow. Low voltage may cause insufficient
heating.

Checking Wiring

High Voltage!
Disconnect all power before servicing
or installing. Multiple power sources
may be present. Failure to do so may
cause property damage, personal injury
or death.
1. Check wiring visually for signs of overheating, damaged
insulation and loose connections.
2. Use an ohmmeter to check continuity of any suspected
open wires.
3. If any wires must be replaced, replace with comparable
gauge and insulation thickness.

AVPTC Motor Orientation

If the unit is in the upflow position, there is no need to
rotate the motor. If the unit is in the downflow position,
loosen motor mount and rotate motor as shown in the
AVPTC Motor Orientation figure below. Be sure motor is
oriented with the female connections on the casing down.
If the motor is not oriented with the connections down,
water could collect in the motor and may cause premature
failure.
