Electric Code (latest revision),

article 310 for power conductor sizing.

 

CAUTION: When more than one field

REMOVAL OF UNIT FROM SKID

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked for external signs of shipping damage. The skid must remain attached to the unit until the unit is ready for installation. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.

UNIT REMOVAL FROM SKID

WARNING

This unit is heavy and requires more than one person to handle and remove from the skid. Check unit wheels to ensure that wheels are locked before removing from skid. Extreme caution must be taken to prevent injury to personnel and damage to the unit.

It is recommended that the unit not be removed from the skid with a fork lift.

The shipping brackets on each side of the unit must be removed and discarded. See Figure 2-A on Page 5. The return air grille panel can be removed to provide a place to hold the unit. The unit can be slid forward on the skid until the front wheels hang over the edge of the skid. See Figure 2-B. The unit can be tipped forward and slid down the edge of the skid until the front wheels touch the ground. See Figure 2-C. The wheels will not roll. They are shipped from the factory locked so they will not roll. The back of the skid will have to be held down to keep it from tipping up. The skid can be slid out from under the unit. The unit can then be set upright.

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 blade of the appliance cart should be slid under the wheels of the unit. See Figure 3. 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.

REMOVAL OF WALL BRACKET FROM SHIPPING LOCATION

The wall brackets are attached to the back of the unit. Remove and retain the wall brackets for use when attaching the unit to the wall. In those installations where a wall sleeve is required these two wall brackets are to be discarded. A different style bracket is supplied with the sleeve assembly.

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 QPB** is recommended.

These instructions explain the recommended method to install the water source 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 1 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. 4-1/2 in. This provides enough clearance to install the duct work. See Figure 6.
