EVAPORATIVE CONDENSERS
APPENDIX
When not in operation the water in the basin may freeze
in the event of very low temperatures. Make sure the basin
is drained whenever the unit is not in operation or use the
heating elements to ensure the water in the basin does not
freeze. Warranty is void in case of non-compliance with
these instructions.
2.7 RESIDUAL HAZARDS WITH REFRIGERANT
WARNING
Danger of injuries!
Halocarbons:
The halocarbon refrigerants that are used (R134a, R404A,
R407C, R507 ...) are Group L1/A1 refrigerants in compliance
with classification according to flammability (L) and toxicity
(A):
• Refrigerants that, when gaseous, are non-flammable ir-
relevant of their concentration in air.
• Refrigerants with a time-weighted, averaged concentra-
tion that have no adverse effects on the majority of staff
that are exposed every day during a normal 8 hour working
day and a 40 hour working week to this concentration,
which is greater than or equal to 400 ml/m
3
(400 ppm
(V/V)).
There is no imminent danger for the staff. With good air
ventilation and removal by suction, it will fall easily and clearly
below the allowed limit values.
WARNING
Danger of harm to health and environmental damage!
Refrigerants of the Group L1/A1 are generally heavier than
air and may flow off to rooms on a lower level. In still air
there may be an increase of the ground level concentration.
With high concentrations there is a danger of suffering from
disordered cardiac rhythm and suffocation due to a reduced
oxygen concentration, especially at ground level.
Unauthorized people must not have access to the unit.
Ensure working rooms are well-ventilated in order to prevent
inhalation of high vapor concentrations.
Please ensure that the halocarbon refrigerant leaking from
the unit cannot penetrate the interior of the building or put
people at risk in any other way. Halocarbon refrigerant vapor
or gas must be kept from penetrating neighboring rooms,
staircases, yards, passages or drainage systems and must
be discharged without risk.
Monitor the halocarbon refrigerant concentration in the
ambient air to ensure constant compliance with limit values.
Test the tightness of the unit regularly, as specified in these
operating instructions (see Appendix I, 6.4 Inspection and
maintenance plan).
Ignition and fire hazard!
• With work involving fire or sparks, ex.
grinding, welding, etc. ensure suitable
firefighting equipment is on-site.
• In particular be aware of the danger
of ignition of residues or halocarbon
refrigerant unintentionally carried in oil.
• Ensure that firefighting equipment is
provided in sufficient quantities, that
it functions properly and that the ex-
tinguishing agent does not react with
the halocarbon refrigerant.
• Smoking during work is prohibited!
Frostbite hazard
Splashing halocarbon refrigerant under
boiling retardation can cause frostbit on
the eyes and skin.
• When removing faults after halocarbon
refrigerant spills, you must be vigilant
for remaining halocarbon refrigerant
still under boiling retardation.
Danger of poisoning!
Halocarbon refrigerant contact with fire
can form toxic combustion products.
• Prevent halocarbon refrigerant contact
with open fire.
• Welding and soldering must therefore
only take place after completely drain-
ing the relevant section of the system
of the halocarbon refrigerant. Ensure
good ventilation!
• With emergency work in high refrig-
erant concentrations in the room air,
wear a room air-independent breathing
apparatus.
Ammonia:
WARNING
Danger of injuries and damage to property with Am-
monia as refrigerant!
Ammonia can cause the following hazard situations and
injuries:
