The Heat Pump D conforms to all safety regula-
tions for electrical measuring, control, monitoring
and laboratory equipment, as specified under
DIN EN 61010, Section 1, and the equipment
has been designed to meet protection class I. It
is intended for operation in a dry environment,
suitable for the operation of electrical equipment
and systems.
Safe operation of the equipment is guaranteed,
provided it is used correctly. However, there is no
guarantee of safety if the equipment is used in an
improper or careless manner.
If it may be assumed for any reason that non-haz-
ardous operation will not be possible (e.g. visible
damage), the equipment should be switched off
immediately and secured against any unintended
use.
In schools and other educational institutions, the
operation of the power supply unit must be super-
vised by qualified personnel.
Before using the heat pump for the first time,
confirm that the specifications printed on the
label are compatible with the local mains volt-
age.
Before using the heat pump, check the device
and the mains lead for any damage. In the
event of any visible damage, switch off the
unit immediately and secure it against unin-
tended use.
The device may only be connected to the
mains via a socket that has an earth connec-
tion.
2. Safety instructions
Risk of overheating: the heat pump's compressor
can get very hot during operation.
Do not hinder the free circulation of air around
the compressor.
Do not thermally insulate the compressor.
After shut-down by the overpressure cut-out
switch wait for 10 minutes to press the green
reset button.
The fluid upon which the heat pump acts (the re-
frigerant) remains under pressure even if the
compressor is switched off.
Carry the heat pump only at the carrying han-
dles.
Do not, under any circumstances, bend or
damage the copper piping.
The refrigerant in its liquid phase must not get
into the compressor. This would overload the
compressor. It is imperative that no lubricant from
the compressor enter into the cooling circuit.
Always keep the heat pump in an upright po-
sition during storage, transport and operation.
Make sure you let the equipment stand up-
right for at least 7 h before initial use if it was
tipped over.
Post heat pump in original box only standing up-
right on its one-way pallet.
