HANDLING UNIT AFTER REMOVAL FROM SKID

WARNING

Exercise extreme caution when pushing the unit on the rollers. Handle and push from the lower 1/3 of the unit. Insure that debris is not on the floor where the unit is to be moved on the rollers. Failure to do so could result in the unit tipping over and causing bodily injury and/ or damage to the unit.

The unit will have to be turned sideways and removed from the skid to fit through a 36" doorway. If the door height allows, the unit can be slid sideways through the door.

If the unit can not be slid through the door, then the unit will have to be put on a cart and tipped down to roll through the door. It is recommended that an appliance cart by used with a strap to hold the unit on the cart. The wheels of the unit must be locked. If the wheels were allowed to roll, the unit could roll off the cart. The unit should always be carted from the left side. This is the side where the compressor is located. See Figure 4.

The blade of the appliance cart should be slid under the wheels of the unit. The strap of the appliance cart should be placed around the unit and strapped tightly. Help will be required to tip the unit back onto the cart. The unit can be leaned far enough back to be rolled through the door. Be careful when setting the unit back up to keep from damaging the unit.

GENERAL

The equipment covered in this manual is to be installed by trained, experienced service and installation technicians.

The unit is designed for use with or without duct work. For use without duct work, Plenum Box QPB42 is recommended.

These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.

These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly “Start Procedure” and any tags and/or labels attached to the equipment.

While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made. See Page 3 for information on codes and standards.

Size of unit for a proposed installation should be based on heat loss calculation made according to methods of Air Conditioning Contractors of America (ACCA). The air duct should be installed in accordance with the Standards of the National Fire Protection Systems of Other Than Residence Type, NFPA No. 90A, and Residence Type Warm Air Heating and Air Conditioning Systems, NFPA No. 90B. Where local regulations are at a variance with instructions, installer should adhere to local codes.

MINIMUM INSTALLATION HEIGHT

The minimum installation height of the unit with a Free Blow Plenum is 8 ft. 6 in. This provides enough clearance for the plenum to be removed. See Figure 5.

The minimum installation height for ducted applications is 8 ft. 4½ in. This provides enough clearance to install the duct work. See Figure 6.
