Contact with parts that could become live when the unit is
started up can result in electric shock, burns or death by
electrocution.
When there is no need for circuits to be powered up, set the
isolating switch on the power line to the OFF position,
padlock it and post a warning sign.
MOVING PARTS
Contact with the fan rotors can cause injury.
Before removing the protective grilles or the fans
themselves, make certain the isolating switch on the power
line to the unit is set to the OFF position and padlocked,
and post a warning sign.
Before removing the protective grilles or the fans
themselves, make certain the isolating switch on the power
line to the unit is set to the OFF position and padlocked,

REFRIGERANT
In the event of safety valves coming into operation and
releasing refrigerant gas, persons in the vicinity can be
injured or suffer toxic effects. Always wear suitable clothing
and protective goggles when working in potential hazard
areas.
In the event of refrigerant gas escaping, refer to the “Safety
datasheet” for the particular refrigerant.
If an open flame or heat source is brought into contact with
the refrigerant, or the pressurized gas circuit should
overheat (e.g. during welding operations), this can cause
explosion or fire. Do not position any heat source within the
hazard area.
Maintenance or repair operations involving welding must be
carried out with the system emptied of refrigerant.
WATER SYSTEM
Defects affecting pipelines, connections or valves and other
control componentry can result in water being leaked or
sprayed from the system, occasioning damage to property
or causing short circuits in the unit.
Make certain all hydraulic connections are securely made,
following the directions given in the present manual.
