INSTALLATION

The system design and installation should follow accepted industry practice, such as described in the ASHRAE Handbook..

Adequate space should be left around the unit for piping coils and drains, filter replacement, and maintenance.. Sufficient space should be provided on the side of the unit for routine service and component removal should that become necessary..

See Service Clearances/Access Panel Locations section for more details..

LIFTING

1)Before lifting, be sure that all shipping material has been removed from unit..

2)To assist in determining rigging requirements, weights are shown below..

3)Unit must be lifted by the eight lifting lugs provided on base structure..

4)Rigger to use suitable mating hardware to attach to unit lifting lugs..

5)Spreader bar(s) must span the unit to prevent damage to the cabinet by the lift cables..

6)Always test-lift the unit to check for proper balance and rigging before hoisting to desired location..

7)Never lift units by weatherhoods.

8)Never lift units in windy conditions.

9)Preparation of curb and roof openings should be completed prior to lifting unit to the roof..

10)Check to be sure that gasketing (supplied by others) has been applied to the curb prior to lifting the unit and setting on curb..

11)Do not use fork lifts for handling unit..

Safety Warning

All factory provided lifting lugs must be used when lifting the units.. Failure to comply with this safety precaution could result in property damage, serious injury, or death..

Position the unit roof opening such that the supply discharge and exhaust inlet of the unit will line up with the corresponding ductwork.. Be sure to allow for the recommended service clearances when positioning opening (see Service Clearances).. Do not face the outdoor air inlet of the unit into prevailing wind and keep the supply inlet of the unit away from any other exhaust fans.. Likewise, position the exhaust discharge opening away from fresh air intakes of any other equipment..

When cutting only duct openings, cut opening 1 inch (25mm) larger than duct size to allow clearance for installation.. Area enclosed by roof curb must comply with clearance to combustible materials.. If the roof is constructed of combustible materials, area within the roof curb must be ventilated, left open, or covered with non-combustible material which has an ÒRÓ value of at least 5.. If area within curb is open, higher radiated sound levels may result..

Where the supply or warm air duct passes thru a combustible roof, a clearance of one inch must be maintained between the outside edges of the duct and combustible material in accordance with NFPA Standard 90A.
