3. Product description
The heating compact installations WPKI-HK E and WPKI-HKM E
are specically designed for buer cylinders SBP 200 E, SBP 400
E and SBP 700 E. In conjunction with the pipe set WPKI RB, they
oer heating contractors a clear and easy means of connecting
the heating system to the SBPE buer cylinder.
The return ball valve contains a gravity brake to prevent unin-
tentional natural circulation. The gravity brake can be opened
manually by turning the handle approx. 45° to its end stop.
The compact heating installation WPKI-HK E is suitable for op-
erating a heating circuit without mixer.
The compact heating installation WPKI-HKM E is suitable for
operating a heating circuit with mixer. The standard delivery
includes a 3-way mixer with servomotor.
3.1 Standard delivery

with 2 m connecting cable
- tow-way ball valve with manual gravity brake in the re-
turn, complete with handle
- tow-way ball valve in the ow, complete with handle
- two thermometers, ø 63 mm, display range 0-120 °C (red
or blue facia ring for identifying the ow and return)
- pump ball valve with ange and 1 ½ “ male (only
WPKI-HKE)
- three-way mixer with variable bypass (only WPKI-HKME)
- return pipe

3-way mixer
A bypass can be used to reduce the ow temperature by mix-
ing in return water. The bypass can be innitely adjusted with
the adjusting screw. For that, undo locking screw 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.
