Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.
Based on 75° C copper wire. All wiring must conform to the National Electrical Code and all local codes.
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National
Electric Code (latest revision), article 310 for power conductor sizing. CAUTION: When more than one field
power conductor circuit is run through one conduit, the conductors must be derated. Pay special attention to Note 8
of Table 310 regarding Ampacity Adjustment Factors when more than three conductors are in a raceway.

UNIT DIMENSIONS
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
HANDLING UNIT AFTER REMOVAL FROM
SKID
W ARNING
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.
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.
REMOVAL OF UNIT FROM SKID
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.
