INSTALLATION INSTRUCTIONS
MOUNTING THE UNIT
When installing a QW unit near an interior wall on the left side, a minimum of 8 inches is required; 12 inches is preferred.
When installing a QW unit near an interior wall on the right side, a minimum of 12 inches is required as additional space is required to connect the drain.
This clearance is required to allow for the attachment of the unit to the wall mounting brackets and the side trim pieces to the wall.
This unit is to be secured to the wall when there is not a vent sleeve used with the wall mounting brackets provided. (NOTE: Wall mounting brackets are only shipped on units with no vent inside.) The unit itself, the supply duct, and the free blow plenum are suitable for “0” clearance to combustible material.
NOTE: When a wall sleeve is to be used attach the unit to the sleeve with bracket supplied with the wall sleeve.
Following are the steps for mounting the QW units. For reference see Figure 11.
1.Attach wall mounting bracket to the structure wall with field supplied lag bolts. The fluid piping connections are to be within the confines of this bracket. See Figure 1 for cabinet openings and location of fluid coil connection points.
2.Position the unit in front of the wall mounting bracket.
3.Remove the locking screws from the wheels. Refer to Figure 10.
4.Roll the unit up to the wall mounting bracket. The unit must be level from side to side. If any adjustments are necessary, shim up under the rollers with sheets of steel or any substance that is not affected by moisture.
5.Secure the unit to the wall bracket with provided #10 hex head sheet metal screws. There are prepunched holes in the cabinet sides, and the bracket has slotted holes to allow for some misalignment.
6.Position the bottom trim piece to the unit and attach with provided screws (dark colored).
7.Position side trim pieces to the wall and attach with field supplied screws. There are two long 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. They may be cut to suit the ceiling height or overlap the unit side trim. There is sufficient length to trim up to a 10'2" ceiling.
