3 Safety instructions and regulations
3.1 Safety instructions
e Incorrect installation can cause electric shock or
appliance damage.
• Never disable security devices and do not try to adjust them.
• Be sure to consider the following handling techniques and
precautions:
• Grip the appliance at its base
• Use safety clothing where appropriate, e.g. gloves, safety
footwear.
• Ensure safe lifting techniques are used:
• Keep back straight.
• Avoid twisting at the waist.
• Avoid upper body/top heavy bending.
• Always grip using the palm of the hand.
• Use designated hand holds.
• Keep load as close to body as possible.
• Always use assistance if required.
• Under no circumstances must the user interfere with or adjust
sealed parts.
• When assembling the connections, correctly position the seals
to avoid any leakage of water.
• This appliance contains metal parts (components) and care
should be taken when handling and cleaning, with particular
regard to edges.
The basic safety instructions must be followed before attempting
to maintain or replace spare parts:
• Stop the appliance.
• Electrically isolate the appliance from the power supply.
• Hydraulically isolate the appliance using the isolation valves if
provided.
• Should you need to replace hydraulic components, drain the
appliance.
• Protect all the electrical components from water while working
on the appliance.
• Use only original spare parts.
• Use only new O-rings and gaskets.
• After having completed work on water carrying components,
check for their tightness.
• When work on the appliance is completed, perform an
operational test and check for safety.
R410A Refrigerant
b Important: any action carried out on the refrigerant
circuit must be performed by qualified personnel.
- Use only R410A refrigerant.
• The tools used for charging, for measuring pressure, for
creating a vacuum and for the recovery of the fluid must be
compatible with and employed solely for R410A.
• Welding is to be carried out with nitrogen and the circuit’s air-
tightness is to be tested under pressure, with nitrogen.
• Refilling must be effected during the liquid phase.
• In case of leakage, do not add fluid: drain the remaining
fluid from the circuit and eliminate, in accordance with the
applicable regulations.
b
Evacuating refrigerant into the atmosphere is
prohibited. The refrigerant must be properly
recovered in a container suitable for recycling.
• Create a vacuum in the circuit with a maximum pressure of 30
mbar (static pressure).
• Bleed the circuit before any welding work.
a Do not smoke or light flames during the emptying
and filling of the circuit. The gases emitted during the
combustion of the refrigerant are flammable.
