REVO-E Heat pump 1 Introduction
– There is a possible risk of suffocation if the refrigerant
leaks into the atmosphere. Refrigerants are heavier
than air. At and beyond a concentration of approx.
12% in the air, there will not be sufficient oxygen to
breathe. Loss of consciousness and increased cardio-
vascular problems caused by stress and lack of
oxygen will result. This is a fatal hazard!
– It is forbidden to smoke when handling refrigerants. A
burning cigarette can break the refrigerant down. Poi-
sonous substances will form as a result.
– Before welding and soldering cooling systems, the
cooling system must be completely evacuated and
any residue removed by blowing in nitrogen. If
exposed to heat, refrigerants will release products of
decomposition that are not hazardous but can also
cause corrosion.
– Nonflammable refrigerants also pose a fire risk via the
ignition of displaced oil residue and insulating material
as well as the oil mist caused by strong leakages.
1.6.4 Working with pressurized containers
– Ensure that the container does not fall over or roll
away
– Do not throw the container. If struck, the containers
may be so deformed that they rupture. Considerable
forces are let free if the heat exchanger is suddenly
struck and refrigerants leak out. The same applies if
cylinder valves break. Therefore, the cylinders are
only to be transported with protective cap.
– Refrigerant cylinders are not to be kept near heating
units. Higher temperatures mean higher pressures,
which may lead to the container exceeding its
maximum allowed pressure. The rules for pressurized
containers stipulate that containers are not to be
warmed beyond 50 °C.
– Never warm refrigerant cylinders with an open flame.
The material may become damaged from the exces-
sive temperature, resulting in decomposition of the re-
frigerant.
– Close empty containers to prevent the entry of mois-
ture.
– Never overfill refrigerant cylinders, since an increase
in temperature can lead to enormous pressures.
1.6.5 Technical rules for pressurized gases
(TRG)
The applicable rules for the manufacturer and workshop
are listed in the Technical Rules for Pressurized Gases
(TRG). Personnel who conducted maintenance and repair
work on the air-conditioning system must know and follow
these rules.
1.6.6 Waste and residual materials
The valid legal conditions and regulations, that concern
waste disposal as well as how to process residual mate-
rial, must be followed.
Disposing of refrigerant and refrigerator oil
The refrigerants to be disposed of are to be placed into the
labeled recycling containers, taking into consideration the
present fill level.
Used refrigerator oils from systems with halogenated
hydrocarbons must be disposed of as special waste. It is
forbidden to mix these with other oils or substances.
Follow country-specific guidelines for proper storage and
disposal.
