1 - INTRODUCTION
Do not attempt to remove refrigerant circuit components or
fittings, while the machine is under pressure or while it is
running. Be sure pressure is at 0 kPa and that the unit has
been shut-down and de-energised before removing
components or opening a circuit.
Do not attempt to repair or recondition any safety devices
when corrosion or build-up of foreign material (rust, dirt,
scale, etc.) is found within the valve body or mechanism. If
necessary, replace the device. Do not install relief valves in
series or backwards.
ATTENTION: No part of the unit must be used as a walkway,
rack or support. Periodically check and repair or if necessary
replace any component or piping that shows signs of damage.
Do not step on refrigerant lines. The lines can break under
the weight and release refrigerant, causing personal injury.
Do not climb on a machine. Use a platform, or staging to work
at higher levels.
Use mechanical lifting equipment (crane, hoist, winch, etc.)
to lift or move heavy components. For lighter components,
use lifting equipment when there is a risk of slipping or losing
your balance.
Use only original replacement parts for any repair or
component replacement. Consult the list of replacement parts
that corresponds to the specification of the original
equipment.
Do not drain water circuits containing industrial brines,
without informing the technical service department at the
installation site or a competent body first.
Close the entering and leaving water shutoff valves and purge
the unit hydraulic circuit, before working on the components
installed on the circuit (screen filter, pump, water flow switch,
etc.).
Periodically inspect all valves, fittings and pipes of the
refrigerant and hydraulic circuits to ensure that they do not
show any corrosion or any signs of leaks.
It is recommended to wear ear defenders, when working near
the unit and the unit is in operation.
Always ensure you are using the correct refrigerant type
before recharging the unit.
Charging any refrigerant other than the original charge type
(R-410A) will impair machine operation and can even lead to
a destruction of the compressors. The compressors operate
with R-410A and are charged with a synthetic polyolester oil.
Before any intervention on the refrigerant circuit, the complete
refrigerant charge must be recovered.
