Installation Instructions, Mounting the Unit

INSTALLATION INSTRUCTIONS

MOUNTING THE UNIT

When installing a QTEC unit near an interior wall on the left side, a minimum of 8 inches is required; 12 inches is preferred.

When installing a QTEC unit near an interior wall on the right side, a minimum of 18 inches is required as additional space is required to connect the side drain. If the rear condensate drain kit QCDS48 is used the minimum can be reduced to 8 inches.

This clearance is required to allow for the attachment of the unit to the sleeve and side trim pieces to the wall.

This unit is to be secured to the wall sleeve with mounting brackets provided. The unit itself, the supply duct and the free blow plenum are suitable of “0” clearance to combustible material.

Following are the steps for mounting the QTEC, for reference see Figure 12 (page 13).

1.Attach mounting brackets to the wall sleeve with screws provided.

2.Position the unit in front of the sleeve with the condenser section toward the sleeve.

3.Remove the locking screws from the wheels. Refer to Figure 13.

4.Roll the unit into the sleeve. Make sure to check both sides of the unit as it is being rolled to keep it centered in the sleeve. Also check the

alignment to the mounting brackets. This unit must be level from side to side. If adjustments are necessary, shim up under the rollers with sheets of steel or any substance that is not affected by moisture.

5.Make sure the gasket on the rear of the unit is touching the sleeve across the top and down both sides. This is a rain water seal.

6.Secure the mounting brackets to the unit with screws provided, #10 hex head sheet metal screws.

7.Bottom trim extensions are provided for use when wall is less than 14 inches but greater than 10.5 inches. Secure to wall with screws (not provided).

8.Attach the bottom trim piece to the unit with the screws provided (dark colored).

9.Position side trim pieces to wall and attach with field supplied screws. There are two long pieces and two short pieces supplied. The long pieces are to enclose the gap behind the unit. The short pieces are to fill the gap behind the cabinet extension or the free blow plenum box. The may be cut to suit your ceiling height or overlap the unit side trim. There is sufficient length to trip up to a 10'2" ceiling.

NOTE: If the exterior wall thickness is between 5 inches to 10.5 inches, a side trim extension piece kit, model QSTX42, is available.
