Hydraulic Connection
5.1
General
If units are not fitted with valves or fitted with valves by others, the installation of the
supply and return lines depends on how medium connections by others are run and/or
used valves types.
5.2
Overview of valves
Various circuit configurations can be used for the supply of both heating and cooling
medium.
Valves with modulating actuator
These valves enable continuous water-side control (modulating operation). If 3-way
valves are fitted by the manufacturer, control is performed via a distributor circuit (refer
to fig. 5-1).
DANGER OF SCALDING BY ESCAPING HEATING MEDIUM!
Before the on-site piping and hydraulic connections of the Hypower-Geko are set
up, the heating/cooling medium must be shut off and secured against inadvertent
opening.
User instructions!
All field cooling medium pipework must be insulated to prevent condensate forma-
tion.
If the pipework is run close to the lateral condensate pan, these lines must be insu-
lated above the lateral condensate pan by others.
When all connections are completed, all bolt/screw connections should be tightened
and checked that they are free of mechanical stress.
User instructions!
The correct direction of medium flow is marked on the valves by an arrow and/or a
letter.
