1. Safety instructions
The Heat Pump D conforms to all safety regulations
for electrical measuring, control, monitoring and labo-
ratory 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 elec-
trical 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-
hazardous 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 su-
pervised by qualified personnel.
• Before using the heat pump for the first time,
confirm that the specifications printed on the la-
bel are compatible with the local mains voltage.
• Before using the heat pump, check the de-
vice and the mains lead for any damage. In
the event of any visible damage, switch off
the unit immediately and secure it against
unintended use.
• The device may only be connected to the mains
via a socket that has an earth connection.
Risk of overheating: the heat pump’s compres-
sor 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
refrigerant) remains under pressure even if the
compressor is switched off.
• Carry the heat pump only at the carrying handles.
• 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 com-
pressor. It is imperative that no lubricant from the
compressor enter into the cooling circuit.
