MIS-1572
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 since the air seal under the unit
could be damaged. See Figure 2.
The shipping brackets on each side of the unit must be
removed and discarded. See Figure 3-A. The return air
grille panel can be removed to provide a place to hold

the unit. The unit can be slid forward on the skit until
the front wheels hang over the edge of the skid. See
Figure 3-B. The unit can be tipped forward and slid
down the edge of the skid until the front wheels touch
the ground. See Figure 3-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 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.

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.
