If the ceiling is lower and no airducts are used, an air ducting elbow (90° NW 160) must be used on the
outlet air side (to ensure effective operation). When an air ducting elbow is used, care must be taken that it is
slipped onto the flange collar of the discharge side in such a way that the discharge opening of the air ducting
elbow is as far away from the intake opening of the unit as possible. Moreover, the minimum clearances shown in
Figure 4 have to be complied with. The air connection fittings, i.e. "intake pipe" and "discharge pipe", of the
HPCDW are identified by adhesive labels.

Installation
¾ From the underside of the pallet, remove the three M12 bolts securing the pallet to the unit as a shipping safety
measure.
¾ Remove the pallet and mount the three levelling feet (M12 bolts – contained in the polybag, secured to the
storage tank pipe nipple).
¾ Move the HPCDW into final position and adjust the unit so that it is perfectly perpendicular by adjusting the
levelling feet! Subsequently, tighten the check nuts provided on the levelling feet.

5.1
Connection of Water Piping
The nominal pipe widths of the field-installed sanitary installations must be determined on the basis of the available
water pressure and the expected pressure losses within the piping system.
The water-side installation has to be executed in compliance with DIN 1988 (see appendix – in the case of
excessive water pipe pressure, a pressure relief valve is to be provided, among other things !)
The water pipes may be of the rigid or flexible type. To prevent corrosion damage, make sure that the materials
used in the piping system are compatible (see section Commissioning).
Caution!
When installing the pipework on the customer's site, any contamination of the piping system
must be avoided (pipes may have to be flushed prior to the connection of the HPCDW)!
