Installation
3.3.7 Remove Wooden Pallet from WPU
The WPU is bolted to a wooden pallet to facilitate safe lifting and transport of the unit. Four bolts attach the
pallet to the unit, as shown in Figure 3-6. The pallet frame is recessed under the WPU to allow for easy
installation while using a forklift. Before completing the mounting of the unit to the wall, remove the pallet by
removing the four bolts.

3.3.8 Install the Support Stand (B5 Cabinet Only)
Support stands should be installed on all 28V1B5 units due to the heavy weight. Place the support stand on
the concrete pad, flush against the wall, and extend the legs to the desired length.
3.3.9 Seal the Joints between WPUs and Wall
To prevent moisture from getting in and air leaking out, coat the joint between the rear panel of the unit and
the wall with a layer of silicone sealant (installer provided, see Table 3-2, item 1) as shown in Figure 3-5.
