Safety
2. Safety
2.1 Areas of application
2.1.1 Application
To prevent unintentional application, which could injure personnel or damage equipment, the
following must be observed:
• The unit must only be used as a heat pump unit intended for water or brine cooling/
heating.
• The unit must not be installed in areas where the relative humidity (RH) may exceed
85% (95% if the motor is made for 100% RH).
• The primary side must only be charged with refrigerant R717.
• Johnson Controls Denmark further accept no liability of any kind for damage to com-
pressor unit and plant parts caused by torsional oscillation or the like which is attribut-
able to built-in VSD solutions initiated by the customer after delivery.
• The secondary side on evaporator and condenser is only intended for water or brine as
cooling/heating medium. The secondary medium is stated at the P&I diagram. Devia-
tions are only permitted with a written permission from Johnson Controls Denmark.
• Installation of the Sabroe heat pump unit in potentially explosive atmospheres must on-
ly take place if it is fitted with approved explosion-proof equipment.
• The compressor must only be used as a refrigeration compressor and within the oper-
ating limits specified in the manual or in a written agreement with Johnson Controls
Denmark.
• The compressor must only be used with the number of revolutions per minute, as
shown on the compressor name plate.
The compressor must NOT be used
• to evacuate the refrigeration plant of air and moisture.
• to put the refrigeration plant under air pressure in view of a pressure testing.
• as an air compressor.
2.1.2 Application of combustion engines
According to EN 378/ISO 5149, no other machinery should be installed in a refrigeration ma-
chine room. Some refrigerant types may, to a certain extent, be absorbed by the fuel in a com-
bustion engine, and when the contaminated fuel reaches the fuel pumps, the refrigerant will
“flash out” (separate) and react on the increased temperature and pressure by creating acids,
which will destroy the pumps. However, check with the local authorities as exemptions to this
rule may be granted.
Warning!
Johnson Controls Denmark is not liable for injuries to personnel or damage to equipment re-
sulting from using the equipment for other purposes than the ones stated above.

Refrigerant - Group For EC PED approval:
Fluid group 1 or 2 according to the PED directive.
Supply voltage - Control Supply voltage and frequency of the control system.
Refrigerant charge
Weight of the refrigerant charge on the unit.
This is only stated if the unit includes an evaporator and/or a
condenser.
Pressure system
The low-pressure side of the unit piping system is referred to as
the LP side.
The high-pressure side of the unit piping system is referred to as
the HP side.
Category
For EC PED approval:
The maximum category of the piping system (CAT 1, 2 or 3) or
of the assembly unit and piping (CAT 3 or 4).
Allowable pressure, max.
The max. pressure (pressure relative to atmospheric pressure)
that the unit/piping system has been designed for in terms of
pressure strength design.
The maximum practical operation pressure is lower than the
maximum allowable pressure depending on the operating condi-
tions and safety equipment settings.
Test pressure The test pressure that the unit/piping system has been strength
tested with.
Allowable temperature,
min./max.
The minimum and maximum temperatures that the unit/piping
system has been designed for at the indicated maximum allow-
able pressures.
CE xxxx
The CE mark appears on the name plate for EC PED approval
only. The four digits make up the registration no. of the notified
body/3rd party in charge.
Ex If the unit is designed in accordance with the EC ATEX directive,
there is an Ex mark on the name plate.
EAC
The EurAsian Conformity mark (EAC) indicates that the unit is in
compliance with all relevant technical regulations of the Eura-
sian Customs Union.

Safety
2.2.5 Signs
All signs which may be found on your equipment are shown below. The number of signs, how-
ever, may vary from one product to another.
Risk of electric shock High voltage/
High pressure
High surface
temperature
(about 70°C)
The compressor may be top-
heavy
Internal overpressure Hazardous substance Cold surfaces Dangerous noise level,
use hearing protectors
Do not step on surface No open flame Flammable gas The unit IS filled with refriger-
ant R290
Internal protection Pacemaker users keep out
Compressor blocks and units are usually
delivered without refrigerant and oil. To
protect the compressors against internal
corrosion, they are delivered evacuated of
all atmospheric air and charged with dry Ni-
trogen (N2) to an overpressure of 0.5 bar
[7.3 PSI].
In such cases, a yellow sign is affixed to a
visible spot on the compressor.
The magnetic field on the rotor may affect
pacemakers. The motor rotor contains a
powerful magnetic field. This field may af-
fect digital devices such as watches and
mobile phones.
Assembly or maintenance of the rotor must
not be carried out by people with pace-
makers or any other implanted medical
electronic device.
The VSD contains capacitors capable of
storing electrical energy, meaning that
there is a risk of electric shock within 15 mi-
nutes after the drive has been turned off.
