Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

NOTE: See dimensional drawing for corner weighs.

Fig. 5 – Unit Suggested Rigging

Step 3 – Provide Clearances

The required minimum service clearances are shown in 

Fig. 2

 and 

Fig. 3

.

Adequate ventilation and outdoor air must be provided. The outdoor fan

draws air through the outdoor coil and discharges it through the top fan

grille. Be sure that the fan discharge does not recirculate to the outdoor

coil.  Do  not  locate  the  unit  in  either  a  corner  or  under  an  overhead

obstruction. The minimum clearance under a partial overhang (such as a

normal house overhang)  is 48  in.  (1219  mm)  above  the unit top. The

maximum horizontal extension of a partial overhang must not exceed 48

in. (1219 mm)

IMPORTANT: 

  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 combustible materials. Slab-mounted units should be at least 2 in.

(51 mm)  above the highest expected water and runoff levels. Do not use

unit if it has been under water.

Step 4 – Field-Fabricate Ductwork

Secure all ducts to roof curb and building structure on vertical discharge

units. Do not connect ductwork to unit. For horizontal applications, unit

is provided with flanges on the horizontal openings. All ductwork should

be  secured  to  the  flanges.  Insulate  and  weatherproof  all  external

ductwork, joints, and roof openings with counter flashing and mastic in

accordance with applicable codes.
Ducts  passing  through  an  unconditioned  space  must  be  insulated  and

covered with a vapor barrier. If a plenum return is used on a vertical unit,

the  return  should  be  ducted  through  the  roof  deck  to  comply  with

applicable fire codes. See unit rating plate for any required  clearances

around ductwork. Cabinet return-air static shall not exceed -.25 IN. W.C.

Step 5 – Rig and Place Unit

Rigging  and  handling  of  this  equipment  can  be  hazardous  for  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.
Training for operators of the lifting equipment should include, but not be

limited to, the following:

1. Application of the lifter to the load, and adjustment of the lifts to

adapt to various sizes or kinds of loads.

2. Instruction in any special operation or precaution.
3. Condition of the load as it relates to operation of the lifting kit, such

as balance, temperature, etc.

Follow all applicable safety codes. Wear safety shoes and work gloves.
