I. LOCATE THE UNIT

A. Clearance

Maintain clearance around and above unit to provide mini- mum distance from combustible materials, proper air¯ow, and service access (see Fig. 2 and 3).

Minimum clearance to combustibles is 0 in. on all sides.

Minimum clearance to block walls or any other grounded sur- face is 42 in. on all sides.

Minimum clearance of 36 in. should be provided on side with outdoor-air intake, if unit is so equipped.

Minimum clearance between unit and other electrically live parts is 48 inches.

Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contami- nated air.

Although unit is weatherproof, guard against water from higher level runoff and overhangs.

Slab mounted units should be at least 4 in. above the highest expected water, ¯ood and runoff levels. Do not use the unit if it has been under water.

Fig. 3 Ð Service and Operational Clearances

B. Roof Curb Mount

Assemble and install accessory roof curb in accordance with instructions shipped with curb. See Fig. 4. Install insulation, cant strips, roo®ng felt, and counter ¯ashing as shown. Duct- work must be attached to curb. If electric or control power is to be routed through the curb, attach the accessory thru-the- bottom connections to the basepan in accordance with the ac- cessory installation instructions. Accessory electric connections must be installed before unit is in place on roof curb.

IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket with the roof curb as shown in Fig. 4. Improperly applied gasket can also result in air leaks and poor unit performance.

Curb should be level. Unit leveling tolerances are shown in Fig. 5. Correct leveling tolerance is necessary for unit drain to function properly.

C. Slab Mount (Horizontal Units Only)

Provide a level concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a gravel apron in front of condenser-coil air inlet to prevent grass and foliage from obstructing air¯ow.

NOTE: Horizontal units may be installed on a roof curb, if required.

II. UNIT DUCT CONNECTIONS

On vertical units, secure all ducts to roof curb and building structure. Do not connect ductwork to unit. On horizontal units, duct ¯anges should be attached to horizontal openings and all ductwork should be secured to ¯anges.

If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable ®re codes.

A minimum clearance is not required around ductwork. Cabi- net return-air static shall not exceed −0.20 in. wg with PARA- BLADE economizer, −0.35 in. wg with Durablade economizer, or −0.45 in. wg without economizer.

NOTE: Connection must be made to roof curb before unit is set in place.

III. RIG AND PLACE UNIT

Inspect unit for transportation damage. File any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit. Rollers may be used to move unit across a roof. Level by us- ing unit frame as a reference. See Table 1 and Fig. 6 for ad- ditional information. Operating weight and maximum weight are shown in Table 1 and Fig. 6.

Lifting holes are provided in base rails as shown in Fig. 6. Refer to rigging instructions on unit.

IMPORTANT: If unit has forklift protection skids, be sure to remove forklift protection skids from under unit before set- ting unit in place.

A properly positioned unit will have the following clearances between unit and roof curb: 1¤4-in. clearance between roof curb and base rails on each side and front of unit; 15¤32-in. clear- ance between roof curb and rear of unit. See Fig. 4, Views A-A and C-C.

After unit is in position, remove shipping materials and rig- ging skids.
