must never be modified to add refrigerant and oil charging, removal and purging devices. All these
devices are provided with the units. Refer to the certified dimensional drawings for the units.
Do not re-use disposable (non-returnable) cylinders or attempt to refill them. It is dangerous and
illegal. When the cylinders are empty, evacuate the remaining gas pressure, and move the cylinders
to a place designated for their recovery. Do not incinerate.
Do not attempt to remove refrigerant circuit components or fittings, when the machine is under
pressure or while it is running. Ensure that the pressure is at 0 kPa 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 safety 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. The refrigerant lines can break
under weight and release refrigerant, causing 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.
Do not drain water circuits containing industrial, brine without informing the technical service
department at the installation site or a competent body first.
Close the entering and leaving water shut off valves and purge the unit water circuit, before working
on the components installed on the circuit (screen filter, pump, water flow switch, etc.).
Do not close the water box bolts until the water boxes have been completely drained.
Periodically inspect all valves, fittings and pipes of the refrigerant and hydronic circuits to ensure
that they do not show any corrosion or any signs of leaks. ,
Wear ear defenders, when working near the unit and the unit and when the unit is running.
