Werecommendinstallingamaintenancevalveinboththeheatingowandheatingreturn–angleddesignforconcealedinstalla-
tion, straight design for surface mounting.
Thereturnlinetotheappliancemusthaveadirttrap.Asludgeseparatorwithmagnetiteseparatorshouldbe
usedtoprotecttheapplianceandthehighefciencypumpfromdirt/sludgeandmagnetite.
Depositsintheheatexchangermayleadtoboilingnoise,adropinperformanceorfaultsintheappliance.

Cold water and DHW connection
A maintenance valve must be installed in the cold water
supply line.
We recommend installing a maintenance valve into the cold
water supply line.
If the cold water supply pressure is above the maximum
permissible operating pressure of 10 bar, install a tested and
certiedpressurereducerinaccordancewithWolfaccessories.
If mixer taps are used, provide a centralised pressure reducer.
Observe the regulations of DIN 1988 [Germany] as well as
those of your local water supply utility when connecting cold
water and DHW.
Your warranty is void if the installation does not comply with
the illustration shown.
Note: When selecting the installation material for the
system, observe engineering standards and take
into account possible electrochemical processes.

with locking cap G¾" (accessories). Install a
safety valve with 3 bar opening pressure on site in
the heating return (see connection kit accessories).
Failure to observe this requirement can result in
material losses on building and equipment due to
uncontrolled water leakage.
