Description
The heating compact installations WPKI HK and WPKI HKM are
specifically designed for buffer cylinders SBP 200 E, SBP 400 E and SBP
700 E. In conjunction with the pipe set WPKI RB, they offer heating
contractors a clear and easy means of connecting the heating system to
the SBP...E buffer cylinder.
The return ball valve contains a gravity brake to prevent unintentional
natural circulation. The gravity brake can be opened manually by turning
the handle approx. 45° to its end stop.
The heating compact installation WPKI HK is designed to operate in an
unmixed heating circuit.
The heating compact installation WPKI HKM is designed to operate in a
heating circuit with a three-way tee mixer with servomotor.

WPKI HKV
The distributor, with 2 connection pairs respectively to the top and
bottom, is designed for the connection of two heating circuits in
conjunction with the heating compact installations WPKI HK and
WPKI HKM.
Specific features of the WPKI HKM
Three-way mixer
A bypass can be used to reduce the flow temperature by mixing in return
water. The bypass can be infinitely adjusted with the adjusting screw
1. For that, undo locking screw 2 approx. 1 mm. Tighten the locking
screw again after completing the adjustment. The mixer is regulated via
the servomotor. In the delivered condition, both mixer and bypass are
closed, and the locking screw is tight.
Servomotor
The angle of rotation is electrically
limited to 90°. Upon reaching its
end stops, the drive will be
switched off and switched to
zero volt. The servomotor can
be switched to manual control via the rotary selector on the casing.

The installation (water and electrical work) and commissioning, as well
as the maintenance of these compact installations, must only be carried
out by a qualified contractor in accordance with these instructions.
Subject to the relevant system, observe the operating and installation
instructions of the components of which the system comprises.
Keep these operating instructions safely and pass them on to any new
user, should the equipment change hands. Let your contractor check
their content in conjunction with any maintenance or repair work.
