Safety

2. Safety

2.1 Areas of application

2.1.1 Application of the heat pump

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 intended for heating and cooling of water or

brine.

• 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 the evaporator and condenser is only intended for water or brine

as process medium. The secondary medium is stated in the P&I diagram. Deviations

are only permitted with a written permission from Johnson Controls Denmark.

• Installation of the heat pump/unit in potentially explosive atmospheres must only take

place if the heat pump is fitted with approved explosion-proof equipment.

• The compressor must only be used as a compressor within the operating limits speci-

fied 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 heat pump of air and moisture

• To put the heat pump 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.

Safety

The unit name plate is positioned on the frame and contains this information:

Serial No. Unique identification number.

Year Year of manufacturing.

Type Manufacturer's type designation.

Scope

For EC PED/EAC approval: ‘Unit & Piping’ means that the CE/

EAC mark applies to the complete unit including the piping sys-

tem.

’Piping’ means that the CE/EAC mark applies to the piping sys-

tem only, and it is the sole responsibility of the owner to ensure

and declare that the complete unit is in conformity with the provi-

sions of all relevant rules.

Design code Design code used for the unit and piping system.

Approval no. If the unit/manufacture has been approved by a 3rd party/noti-

fied body.

Refrigerant - Fluid Refrigerant of the unit.

Refrigerant designation according to ISO 817.

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.

Note: Main supply voltage can be found on the motor and/or electrical panel name plate.

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.
