A242-1 Wall Sleeve Adaptor Kit

The A242-1 wall sleeve adaptor kit is designed to allow for the installation of current 43" tall HW/HWC units into 48" tall wall sleeves (CA241 wall sleeve kits). The CA241 wall sleeve kits were designed for use with HW/ HWC121, 181, 241 and 301 units manufactured during the late 1980’s. The HW/HWC series 1 units were approximately 48" tall.

If replacement of the wall sleeve is not feasible, use of the A-242-1 adaptor kit creates an insulated block-off panel at the top portion of the CA241 wall sleeve.

The adaptor kit also allows for easy mounting of the HW/HWC unit to the taller sleeve.

Whenever it is necessary to convert a CA241 wall sleeve to current unit dimensions, use of the A242-1 adaptor kit is required.

Inspection of Shipment

Upon receipt of equipment, carefully inspect it for possible shipping damage. If damage is found, it should be noted on the carrier’s freight bill. Damage claims should be filed with the carrier immediately. Claims of shortages should be filed with the seller within five days.

Wall Sleeve Adaptor Kit Assembly

Once assembled, the A242-1 adaptor kit will form a rectangular box approximately 4-7/8" tall with approximately 7/8" overlapping the front and side of the top panel of the HW/HWC unit (see Figure 7-2 on page 7-9).

To assemble the adaptor kit:

1.Set top flanges of side and front panels on the floor or ground so that they are resting flat. The screw holes through the side flanges of front panel should align with the pilot holes in side panel.

2.Fasten two #8 x 1/2" screws in each side.

3.Place rear panel against the rear flanges of the side panels. The screw holes of the rear panel should align with the pilot holes in the side panel rear flanges.

4.The top and bottom flanges of the rear panel should be facing the front panel. The five 1/4" pilot holes should be positioned towards the bottom of the kit and the five oval screw holes should be positioned towards the top of the kit.

5.Fasten two #8 x 1/2" screws at each end of the rear panel.
