Failure to read and follow these instructions can result in property damage, severe personal injury or death. This equipment must be installed by experienced, trained personnel only.

Inspection

When the equipment is received, all items should be carefully checked against the bill of lading to be sure all crates and cartons have been received. All units should be carefully inspected for damage when received. If any damage is noticed, the carrier should make the proper notation on the delivery receipt acknowledging

the damage. The carrier should also ll out a Carrier Inspection Report. The McQuay International Trafc Department should then be notied. The unit nameplate

should be checked to make sure the voltage agrees with the power supply available. This unit is designed and built for through-the-wall installation in either new

or existing buildings. The self-contained refrigerant

system delivers cooling to the desired space. Heating is accomplished with a top mounted hydronic heating coil.

Each conditioner consists of the following components:

1. Cooling Chassis – Shipped separate in a single carton.

2. Wall Sleeve – Shipped separate in a single carton or in a multi-pack of 15.

3. Hydronic Heat Section – Shipped in a separate carton.

4. Outdoor Louver – Shipped in a separate carton.

5. Room Cabinet – Shipped in a separate carton with kickplate attached.

IMPORTANT

This product was carefully packed and thoroughly inspected before leaving the factory. Responsibility for its safe delivery was assumed by the carrier upon acceptance of the shipment. Claims for loss or damage sustained in transit must therefore be made upon the carrier as follows:

VISIBLE LOSS OR DAMAGE

Any external evidence of loss or damage must be noted on the freight bill or carrier’s receipt, and signed by the carrier’s agent. Failure to adequately describe such external evidence of loss or damage may result in the carrier’s

refusal to honor a damage claim. The form required to le

such a claim will be supplied by the carrier.

CONCEALED LOSS OR DAMAGE

Concealed loss or damage means loss or damage which does not become apparent until the product has been unpacked. The contents may be damaged in transit due to rough handling even though the carton may not show external damages. When the damage is discovered upon unpacking, make a written request for inspection by the

carrier’s agent within fteen (15) days of the delivery date.

File a claim with the carrier since such damage is the carrier’s responsibility.

Installation

The room cabinet is the last piece to install. The following instructions assume all components (wall sleeve, heat section, louver and chassis) have been installed, piped and anchored.

All major room construction should also be complete so as not to damage the room cabinet after it has been installed. Attaching the room cabinet can be completed as follows:

1. Firmly grip the room cabinet and lift it over the heat

section. There are notches in the back anges of the

room cabinet that rest on the wall sleeve to assure it is centered (Figure 1 detail).

2. Align the notches of the room cabinet on the wall sleeve

and rmly push the cabinet downward until it seats on

the wall sleeve. (Figure 1).
