5 − Do not locate the unit where the combustion air supply will be exposed to any corrosive substance, including the following:

Permanent wave solutions, Chlorinated waxes or cleaners, Chlorine−based swimming pool chemicals, Water−softening chemicals,

De−icing salts or chemicals, Carbon tetrachloride, Halogen−type refrigerants,

Cleaning solvents (e.g., perchloroethylene), Printing inks, paint removers, varnishes, etc., Cements and glues,

Anti−static fabric softeners used in clothes dryers, Masonry acid−washing materials,

Chlorinated laundry products,

Hydrochloric acid.

Rigging & Setting Unit

Exercise care when moving the unit. Do not remove any packaging until the unit is near the place of installation. An optional lifting lug kit (92M51) may be purchased separately for use in rigging the unit for lifting. The spreader lengths must exceed the width across the top of the unit. Recommended spreader lengths: for use with 2, 2−1/2 and 3−ton units −− 44"; for use with 3−1/2, 4 and 5−ton units −− 54".

CAUTION

Before lifting a unit, make sure that the weight is dis- tributed equally on the cables so that it will lift evenly.

Units may also be moved or lifted with a forklift while still in the factory supplied packaging.

NOTE − Length of forks must be a minimum of 42 inches.

Clearances

All units require certain clearances for proper operation and service. Refer to figure 2 for the clearances required for combustible construction, servicing, and proper unit operation.

NOTE − Do not permit overhanging structures or shrubs to obstruct condenser air discharge outlet or vent outlet.

Figure 2

In the U.S. units may be installed on combustible flooring made from wood or class A, B, or C roof covering material. In Canada, units may be installed on combustible flooring. The products of combustion are discharged through a screened vent outlet in the front mullion.

Install the unit so that the products of combustion will not damage the outer building structure.

The vent outlet must be at least 4 feet below, 4 feet horizontally from and 1 foot above any door, window or gravity air inlet into the building. In addition, install the unit so that the vent outlet is at least 3 feet above any forced air inlet located within 10 feet.

Clearances to the vent outlet must also be consistent with the requirements of the current National Fuel Gas Code (Z223.1) and/or the standards of the current CSA B149 codes.

Figure 3 shows the minimum clearances to combustibles required above and below the vent hood. The minimum clearance in front of the vent hood is 24 inches.

Install the unit so that snow accumulation will not restrict the flow of the flue products. Allow a required minimum horizontal clearance of 4 feet from electric meters, gas meters, regulators and relief equipment. In addition to the above requirements, ensure that unwanted ice caused by condensate is not allowed to accumulate around the unit. Do not locate the unit on the side of the building where the prevailing winter winds could trap moisture, causing it to
