NOTES:
1.
Boldface
indicates a field-supplied drive is required. (See Note 8.)
2. indicates an alternate motor and drive are required.
3. indicates a field-supplied motor and drive are required.
4. indicates maximum usable watts of a factory-supplied motor.
5. Maximum usable watts input is 3775 with a standard motor and 4400 with an
alternate motor. Extensive motor and electrical testing on these units ensures
that the full range of the motor can be utilized with confidence. Using your fan
motors up to the wattage ratings shown will not result in nuisance tripping or
premature motor failure. Unit warranty will not be affected. For additional
information on motor performance, refer to Table 9.
6. Values include losses for filters, unit casing, and wet coils.
7. Use of a field-supplied motor may affect wire sizing. Contact your representa-
tive to verify.
8. Standard motor drive range: 860 to 1080 rpm. Alternate motor drive range:
900 to 1260 rpm. All other rpms require field-supplied drive.
9. To convert watts to bhp:
Motor efficiency = .80 (Std)
.87 (Alt)
B. Ventilation Sequence
If unit is equipped with an Durablade economizer or two-
position damper, the damper will open to the minimum posi-
tion whenever the evaporator fan runs.
The damper motor will be energized with 24-vdc power and
damper will drive open until SW3 on the damper is deacti-
vated. The damper motor will stop and damper will remain
in the minimum ventilation position until the evaporator fan
is shut off. When the evaporator fan is shut off, the damper
motor is again energized and the damper runs closed until
SW2 is activated and the damper motor turns off.
CARE AND MAINTENANCE
To ensure continuing high performance and to minimize the
possibility of premature equipment failure, periodic mainte-
nance must be performed on this equipment. This combina-
tion heating/cooling unit should be inspected at least once
each year by a qualified service person.
NOTE TO EQUIPMENT OWNER: Consult your local dealer
about the availability of a maintenance contract.
The minimum maintenance requirements for this equipment
are as follows:
1. Inspect air filters each month. Clean or replace when
necessary.
2. Inspect cooling coil, drain pan, and condensate drain each
cooling season for cleanliness. Clean when necessary.
3. Inspect blower motor and wheel for cleanliness.
Inspect belts, and belt tension each heating and cool-
ing season. Clean, adjust or replace when necessary.
4. Check electrical connections for tightness and con-
trols for proper operation each heating and cooling
season. Service when necessary.
5. Check and inspect heating section before each heat-
ing season. Clean and adjust when necessary.
6. Check and clean vent screen if needed.
