INSTALLATION
Jobsite Survey
Complete the following checks before installation.
1. Consult local building codes and the NEC (National Elec-
trical Code) ANSI/NFPA 70 for special installation
requirements.
2. Determine unit location (from project plans) or select unit
location.
3. Check for possible overhead obstructions which may
interfere with unit lifting or rigging.
Step 1 — Plan for Unit Location
Select a location for the unit and its support system (curb or
other) that provides for the minimum clearances required for
safety. This includes the clearance to combustible surfaces,
unit performance and service access below, around and above
unit as specified in unit drawings. See Fig. 4 (for size 08 and 09
units) and Fig. 5 (for size 12 units).
NOTE: Consider also the effect of adjacent units.
Unit may be installed directly on wood flooring or on Class A,
B, or C roof-covering material when roof curb is used.
Do not install unit in an indoor location. Do not locate air inlets
near exhaust vents or other sources of contaminated air.
Although unit is weatherproof, avoid locations that permit wa-
ter from higher level runoff and overhangs to fall onto the unit.
Select a unit mounting system that provides adequate height to
allow for removal and disposal of frost and ice that will form
during the heating-defrost mode as well as allow installation of
condensate trap per requirements. Refer to Step 10 — Install Ex-
ternal Condensate Trap and Line on page 17 for required trap di-
mensions.
ROOF MOUNT
Check building codes for weight distribution requirements.
Unit operating weight is shown in Table 5.
Step 2 — Plan for Sequence of Unit Installation
The support method used for this unit will dictate different se-
quences for the steps of unit installation. For example, on curb-
mounted units, some accessories must be installed on the unit
before the unit is placed on the curb. Review the following for
recommended sequences for installation steps.
CURB-MOUNTED INSTALLATION
1. Install curb
2. Install field-fabricated ductwork inside curb
3. Install accessory thru-base service connection package
(affects curb and unit) (refer to accessory installation
instructions for details)
4. Prepare bottom condensate drain connection to suit
planned condensate line routing (refer to Step 10 — Install
External Condensate Trap and Line on page 17 for details)
5. Rig and place unit
6. Install outdoor air hood
7. Install condensate line trap and piping
8. Make electrical connections
9. Install other accessories
PAD-MOUNTED INSTALLATION
1. Prepare pad and unit supports
2. Check and tighten the bottom condensate drain connection
plug
3. Rig and place unit
4. Convert unit to side duct connection arrangement
5. Install field-fabricated ductwork at unit duct openings
6. Install outdoor air hood
