QW SERIES WATER SOURCE GENERAL INFORMATION

QW MODEL NOMENCLATURE

1Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors.

2Based on 75°C copper wire. All wiring must conform to the National Electrical Code and all local codes.

3These “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.

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.

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 7. 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.

FIGURE 2

HOLD SKID DOWN

ASHIPPING BRACKETS BFRONT WHEELS OVER EDGE CFRONT WHEELS ON FLOOR

MIS-1603

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 3.

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.

UNIT REMOVAL FROM SKID

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.

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.

Manual 2100-419E

Page 8 of 48

REMOVAL OF WALL BRACKET FROM

SHIPPING LOCATION (UNITS WITH

BLANK OFF PLATE ONLY)

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 units equipped with a

ventilator a wall sleeve is required and these two wall

brackets are not included. 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 4 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.
