5 Commissioning
WPM II
See the operating instructions for the
heat pump manager WPM II.
Since the WPL....A / AS, I and IK /
IKS are heat pumps with internal HS 2, please
observe the WP type 2 when reading the
description of the individual functions.
After commissioning, the installer should
complete the commissioning report on pages
17 to 19.
6 Operation and control
WPM II
A WPM II heat pump manager is
required to operate the heat pump
(already an integral part of the
WPL....IK / IKS). It regulates the entire heating
system. and all required adjustments are
made at this control unit.
Please note: The WPL....A / AS, I and IK / IKS
are WP type 2.
Only qualified contractors must adjust the
WPM II heat pump manager.
Never interrupt the heat pump power
supply, even outside the heating
season otherwise the system would not be
protected from frost. Generally, the system
does not need to be shut down during
summer, as the WPM II is provided with
an automatic summer/winter changeover
facility. Set the WPM II to standby when
the system is taken out of use. This retains
the safety functions designed to protect the
system
(e.g. frost protection).
Drain the water side of the heat pump if
there is a risk of frost, and the heat pump
has been completely shut down.
7 Maintenance and cleaning
Maintenance
The heat pump operates under automatic
control and requires no specific maintenance.
If heat meters are installed, frequently clean
their strainers, which block easily.
Keep the air inlet and outlet apertures of the
heat pump free from snow and leaves.
Cleaning
Regularly remove all leaves and accumulated
dirt from the evaporator fins, which are
accessible after the casing parts on the
condenser side have been removed.
Check the condensate drain at least once every
month (visual inspection). Remove dirt and
blockages immediately.
Faults
When the heat pump operation is impaired
through deposits of corrosion products (rust
sludge) inside the condenser, the customer
service can only use solvents and a flushing
pump to remove such deposits.
