SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should
install, repair, or service air-conditioning equipment.
Untrained personnel can perform basic maintenance func-
tions of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on air-conditioning equipment, observe pre-
cautions in the literature, tags and labels attached to the unit,
and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves.
Use quenching cloth for unbrazing operations. Have fire ex-
tinguishers available for all brazing operations.
WARNING:
Before performing service or mainte-
nance operations on unit, turn off main power switch
to unit. Electrical shock could cause personal injury.
IMPORTANT:
Units have high ambient operating limits. If
limits are exceeded, the units will automatically lock the com-
pressor out of operation. Manual reset will be required to re-
start the compressor.
INSTALLATION
I. STEP 1 — PROVIDE UNIT SUPPORT
A. Roof Curb
Assemble and install accessory roof curb or horizontal adapter
roof curb in accordance with instructions shipped with the
curb or horizontal adapter. Accessory roof curb and horizon-
tal adapter roof curb and information required to field fabri-
cate a roof curb or horizontal adapter roof curb are shown in
Fig. 1 and 2. Install insulation, cant strips, roofing, and counter
flashing as shown. Ductwork can be secured to roof curb be-
fore unit is set in place.
IMPORTANT:
The gasketing of the unit to the roof curb or
adapter roof curb is critical for a leak-proof seal. Install gas-
ket supplied with the roof curb or adapter roof curb as shown
in Fig. 1. Improperly applied gasket can result in air leaks
and poor unit performance.
Curb or adapter roof curb should be level. This is necessary
to permit unit drain to function properly. Unit leveling toler-
ance is
6
1
⁄
16
in. per linear ft in any direction. Refer to Ac-
cessory Roof Curb or Horizontal Adapter Roof Curb Installa-
tion Instructions for additional information as required.
B. Alternate Unit Support
When the curb or adapter cannot be used, support unit with
sleepers using unit curb or adapter support area. If sleepers
cannot be used, support long sides of unit with a minimum of
3 equally spaced 4-in. x 4-in. pads on each side.
II. STEP 2 — RIG AND PLACE UNIT
Inspect unit for transportation damage. File any claim with
transportation agency. Keep unit upright, and do not drop.
Use spreader bars over unit to prevent sling or cable dam-
age. Rollers may be used to move unit across a roof. Level by
using unit frame as a reference; leveling tolerance is
6
1
⁄
16
in. per linear ft in any direction. See Fig. 3 for addi-
tional information. Unit weight is shown in Table 1.
Four lifting holes are provided in ends of unit base rails as
shown in Fig. 3. Refer to rigging instructions on unit.
A. Positioning
Provide clearance around and above unit for airflow, safety,
and service access (Fig. 4 and 5).
Do not install unit in an indoor location. Do not locate air in-
lets near exhaust vents or other sources of contam-
inated air.
Although unit is weatherproof, guard against water from higher
level runoff and overhangs.
B. Roof Mount
Check building codes for weight distribution requirements.
