1 Safety instructions

■ Always obey the safety regulations,
warnings, comments and instructions
given in this document. When the safety
regulations, warnings, comments and
instructions in this document are not
obeyed personal injury or damage to the
unit can occur;
■ Always obey the general and locally
applicable construction, safety and
installation instructions of the local
council, electricity and water boards or
other agencies;
■ Never lift the unit alone. It is heavy and
must be mounted precisely;
■ Fitting to a ventilation unit mounted
on a wall is NOT permitted for safety
reasons.
■ Always connect air ducts of at least
900mm to the unit before you connect
the power to the unit. This ensures the
cooling skid cannot be touched while
the unit is active;
■ After installation all parts that can cause
personal injury are secured behind the
casing. Tools are required to open the
casing;
■ The installation, commissioning and
maintenance must be carried out by
a certified engineer unless instructed
differently. A non-certified engineer can
cause personal injury or damage the
performance of the ventilation system;
■ Do not modify the unit or the
specifications given in its documents. A
modification can cause personal injury
or damage the performance of the
ventilation system;
■ Always disconnect the power supply of
the unit before you start working on the
ventilation system. The unit can cause
personal injury when it is open while
running. Make sure the unit cannot
switch back on by accident;
■ Always take ESD-inhibiting measures
when dealing with electronics, such as
wearing an antistatic wristband. The
electronics can be damaged by static
charges;
■ Only a recognized cooling-technology
fitter is permitted to carry out work on
the cooling skid;
■ The unit contains coolant R134a.
This is a non-flammable, non-toxic
coolant. Handle the cooling skid
with great care during installation
or maintenance activities to prevent
coolant from leaking. Anyone involved
in maintenance, repair or recycling of
the product should wear gloves and eye
protection at all times;
■ When welding or soldering in the vicinity
of the coolant, always wear breathing
equipment fitted with a filter. The filter
should provide protection against
eventual decomposition products;
■ If coolant leaks in anyway due to a
defect or damage, then:
- Open windows and doors in the room
in which the unit is located for at least
an hour;
- The unit contains 0.5kg (at room
temperature approx. 0.2m3) coolant;
- The coolant is heavier than air and will
concentrate on the floor;
- Never try to contain the escaped gas
and do not breath it in;
- In the event of skin or eye contact,
rinse for at least 20 minutes with
lukewarm water, and contact your
doctor.
