2.3 Safety and regulation devices

The domestic hot water heat pump is equipped with the following
safety devices:
High pressure switch (HP)
The high pressure switch protects the heat pump against
impermissibly high operating pressure in the refrigerant circuit,
and switches the heat pump off in the event of a fault. The heat
pump restarts automatically as soon as the pressure in the
refrigerant circuit has dropped again.
Safety temperature limiter for heating element
(STL)
The STL protects the domestic hot water system against
impermissible temperature increases.
The heating element switches off if the set switching value
(99 °C) is exceeded.
The heating element cannot be switched on again until the
domestic hot water temperature has decreased to ≤90 °C and
the reset button (see illustration) on the STL is pressed (this must
only be done by qualified personnel).
The domestic hot water heat pump is also equipped with the
following regulation and control devices:
Heat pump temperature controller
Temperature control in the domestic hot water cylinder and the
regulation for compressor operation is carried out by the control
electronics. Electronic sensors measure the water temperature,
which is regulated based on the setpoint. The desired
temperature level (setpoint) is set via the keypad on the control
panel.
Air intake temperature
The sensor connected to the controller measures the
temperature in the domestic hot water heat pump directly in front
of the evaporator (air intake temperature). If the temperature falls
below the set switching value (8 ±1.5 °C, switch-back value 3 K),
domestic hot water preparation automatically switches from heat
pump operation to heating element operation. With the BWP
30HSD version, the evaporator
predetermined runtime has elapsed when the temperature is
below 8 °C. At temperatures below -8 °C, the controller switches
from heat pump operation to heating element operation in this
case.

Storage and transport

3.1 General

The domestic hot water heat pump should always be stored and
transported packaged in an upright position, without being filled
with water. If handled carefully, the device can be transported
over short distances with a maximum tilt angle of 45°. Ambient
temperatures between -20 and +60 °C are permissible during
transport and storage.

3.2 Fork lift (or lift truck) transport

The domestic hot water heat pump must remain mounted on the
pallet when being transported with a fork lift. The pump should be
lifted slowly. Because of its high centre of mass, the domestic hot
water heat pump must be secured against toppling. To prevent
damage, the domestic hot water heat pump must be lowered
onto a level surface.

3.3 Manual transport

The wooden pallet can be used underneath the device for the
purpose of manual transportation. A second or third carrying
position can be created with the help of ropes or carrying slings
(these may be wrapped around the hot water cylinder casing and
attached to the water pipe nipples, for which purpose the plastic
front cover must first be removed). If the pump is transported in
this manner (or with a hand truck), do not, under any
circumstances, exceed the maximum tilt angle of 45° (see
illustration).
ATTENTION!
The device cover cannot be used for carrying (the cover cannot withstand
larger forces!)
