Step 1
—
Complete Pre--Installation Checks
Unpack Unit
Move the unit to final location. Remove unit from carton,
being careful not to damage service valves and grilles.
Inspect Shipment
File a claim with the shipping company if shipment is damaged or
incomplete. Check the unit nameplates to ensure units match job
requirements.
Consider System Requirements
Consult local building codes and NEC for special installation
requirements.
Allow sufficient space for airflow clearance, wiring, refrigerant
piping, and servicing unit. See Fig. 2.
Locate unit so that condenser airflow is unrestricted on both sides.
Refer to Fig. 2.
Unit may be mounted on a level pad directly on base legs or
mounted on raised pads at support points. See Fig. 2 for center of
gravity.
Matching the Condensing Unit to an Indoor Unit
The 38HDR018--060 ducted condensing units can be matched to
corresponding indoor units. The 38HDR unit can be matched with
under--ceiling and residential fan coils and evaporator coils. Refer
to separate indoor unit literature for more information.

RIG AND MOUNT UNIT
Mounting on Ground
Mount unit on a solid, level concrete pad. Position unit so water or
ice from roof does not fall directly onto unit. Accessory stacking
kits can be used when units are to be stacked. See installation
instructions provided with the accessory kit. Use field--provided
snow stand or ice rack where prolonged subfreezing temperatures
or heavy snow occurs.
If conditions or local codes require unit be fastened to a pad, 6
field--supplied tiedown bolts should be used and fastened through
slots provided in unit mounting feet.
Mounting on Roof
Mount unit on a level platform or frame at least 6 in. (152.4 mm)
above roof surface. Isolate unit and tubing from structure.
