If the unit is to be installed on a hot sun exposed roof or a
black-topped ground area, the unit should be raised sufficiently
above roof or ground to avoid circulating the accumulated layer
of hot air into the outdoor unit.
Be sure to provide an adequate structural support. This unit is
heavier than a conventional outdoor section. Refer to Table 2
for operating weight. Concrete structural support is recom-
mended. Wood curbing and plastic are unacceptable.
The unit may be installed at ground level on a solid base that
will not shift or settle, causing strain on the refrigerant lines and
possible leaks. Maintain the clearances shown in Figure 4 and
install the unit in a level position. Isolate the unit from rain
gutters to avoid any possible wash out of the foundation. Also,
isolate the base from the building structure to avoid noise or
vibration transmission.
When installing the unit on a roof, the structure must be capable
of supporting the total weight of the unit, including a pad, lintels,
rails, etc., which should be used to minimize the transmission
of sound and vibration into the conditioned space.
Normal operating sound levels may be objectionable if the unit
is located close to certain rooms (bedrooms, study, etc).
Condensate will drain from beneath the coil of the unit during
the defrost cycle. A gravel bed may be used to prevent mud
splashing, A limestone gravel is recommended to be added
around unit and under engine exhaust as a condensate neu-
tralizer.
Elevate the unit sufficiently to prevent any blockage of the air
entrances by snow in areas where there will be snow accumu-
lation. Check the local weather bureau for the expected snow
accumulation in your area. The owner should remove any snow
accumulation.
INSTALLATION PROCEDURES
The following sequence of installation steps is suggested. Also
refer to Installation Checklist, page 24 of this instruction.
1. Inspect the unit and set in place.
2. Make electrical power connections.
3. Route the gas piping and connect to unit.
4. Route the vapor and liquid lines.
5. Leak test refrigerant lines.
6. Make electrical control connections.
*7. Evacuate and charge refrigerant system.
8. Power up outdoor section first, then indoor section.
9. Start and check system for proper operation.
10. Instruct owner on operation of unit.
*Unit is charged with enough refrigerant for outdoor unit,
indoor unit and 15 ft. of each line.

* For electric heat or add-on hot water hydronic heat applications, if
ambient will be below this, or above 75 DB (in heating) the
compression cycle will stop but backup heating will continue.
** Operation below this temperature is permissible for a short period
of time during morning warmup.
*** For furnace applications, if ambient is below this value, compression
cycle will stop and furnace will operate.
TABLE 1 - APPLICATION LIMITATIONS
WARNING: The unit must not be located within 4 feet
of doors windows or other openings to the living space.
Products of combustion exhausted from the unit could
enter the living space and cause injury or death.
CAUTION: Do not tip the unit more than 20
°
in any
plane while setting unit in place. If tipped, unit may not
be run for 24 hours to allow oil to drain back into the
sump.
NOTE: An engine exhaust extension (max. 4 ft.) may
be added to redirect the exhaust, but it must continu-
ously slope downhill to prevent condensate from being
trapped and/or frozen in the extension.
WARNING: The outdoor unit should not be installed in
an area where mud or ice could cause personal injury.
Remember that condensate will drip from the unit coils
during heat and defrost cycles. This condensate will
freeze when the outdoor air temperature is below 32
°
F.
NOTE: A service analyzer is required for unit start-up.
An
oxygen
(O
2
) analyzer is required for proper
unit
operation.
