PROCEDURE 3--PROVIDE CLEARANCES

The required minimum service clearances are shown in Figs. 2 and 3. Adequate ventilation and outdoor air must be provided. The outdoor fire &aws air through the outdoor coil and discharges it through the top fun grille. Be sure that the fan discharge does not recirculate to the outdoor

coil. Do not locate the unit in either a comer or under an overhead obstruction. The minimum clearance under a partial overhang (such as a no*real house overhang) is 36 in. above the unit top. The maximum horizontal extension of a partial overhang must not exceed 48 in. For extended

overhangs, provide a minimum clearance of 48 in mMPORTANT: Do not restrict outdoor airflow. An air restriction at either the outdoor-air inlet or the fan discharge may be detrimental to

compressor life. Do not place the unit where water, ice, or snow from an overhang or roof will damage or flood the unit. Do not install the unit on carpeting or

other comhustible materials. Slab-mounted units should be at least 4 in. above the highest expected water and runoff levels. Do not use unit if it has been under water.

PROCEDURE 4--RIG AND PLACE UNmT Rigging and handling of d_is equipment can be hazardous %r many reasons due to the installation location (roofs, elevated structures, etc.)

Only trained, qualified crane operators and ground support staff should handle and install this equipment When working with this equipment, observe precautions in the literature, on tags, stickers, and labels attached to the equipment, and any other

safety precautions that might apply. Follow all applicable safety codes. Wear safety shoes and work gloves.

A. mNSPECTION

Prior to initial use, and at monthly intervals, all rigging brackets and straps should be visually inspected for any damagQ evidence of wear, structural defbm_atiom or cracks. Particular attention should be paid to excessive wear at hoist hooking points and load support areas. Brackets

or straps showing any kind of wear in these areas must not be used and should be discarded.

B. mNSTALLATION

1. Remove unit from shipping carton Leave top shipping skid on the malt as a spreader bar to prevent the rigging straps from damaging the unit If the wood skid is not available, use a spreader bar of sufficient length to protect unit f?om damage.

2 Position the lifting bracket assembly around the base of the unit. Be sure the strap does not twist 3 Place each of the 4 metal lifting brackets into the rigging holds in the composite pan

PROCEDURE 5--SELECT AND BNSTALL DUCTWORK

The design and installation of the &/ct system must be in accordance with the standards of [l_e NFPA [br installation of non-residence type air conditioning and ventilating systems, NFPA 90A or residence type, NFPA 90B and/or local codes and ordinances.

Select and size ductwork, supply=air registers, and remm air grilles according to ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) recommendations.

The unit has duct flanges on the supply- and return-air openings on the side of the unit. When designing and installing ¢lt/ctwork_ consider the following:

z_ WARNING: For vertical supply and return units, tools or parts could drop into ductwork and cause serious injury or

death. Install a 90 degree turn in the return ductwork between the unit and the conditioned space. If a 90 degree elbow cannot be installed, then a grille of sufficient strength and density should be installed to prevent objects from falling into the

conditioned space. Units with electric heaters require 90 degree elbow in supply duct.

1. All units shonld have field=supplied filters or accessory filter rack installed in the return-air side of the unit. Recommended sizes %r filters are sho_xn in Tables 1 and 2

2. A_oid abla/pt duct size increases and reductions. Abrupt change in duct size adversdy affects air performance.

The units dispose of condensate through a 3/4 in. NPT female fitting that exits on the compressor end of the unit Condensate water can be &ained directly onto the roof in toot'top installations (where permitted) or onto a gravel apron in ground level installations. Install a field=supplied

condensate trap at end of condensate connection to ensure proper drainage. Make sure that the outlet of the trap is at least 1 in. lower than the &ain-pan condensate connection to prevent the pan l:i'om overflowing. Prime the a'ap with water. When using a gravel apron, make sure it slopes

away fi'om the unit. If the installation requires draining the condensate water away fi'om the unit. install a field=supplied 2=in. tIap at the condensate connection to

ensure proper drainage. (ondensate trap is available as an accessoE¢ or is field-supplied. Make sure that the outlet of the trap is at least 1 in. lower than the unit &ain-pan condensate connection to prevent the pan t'rom overflowing. Connect a drain trough using a mininmna of field=supplied 3/4

-in. PVC or field-supplied 3/4 -in. copper pipe at outlet end of the 2 =in. trap (See Fig. 12). Do not undersize the robe. Pitch the drain trough downward at a slope of at least 1 in. ever}' 10 it. of horizontal run. Be sure to check the &ain trough for leaks. Prime the tIap at the beginning

of the cooling season start-up.
