Top-up / Replacement of Refrigerant Charge
The units are factory-tested with the gas charge necessary for correct
operation. The amount of gas inside the circuit is shown directly on the
serial no. plate. Should the R410A need to be topped-up, drain and
evacuate the circuit, eliminating traces of non-condensable gases with
any humidity. After maintenance, the gas charge must be restored after
the cooling circuit has undergone maintenance and been accurately
clean.
Subsequently, restore the exact amount of new refrigerant indicated
in the serial number plate. The refrigerant must be piped from loading
cylinders in liquid phase in order to ensure the correct proportions (R32/
its work conditions for at least 24 hours. If, for any particular reason,
such as a refrigerant leak, you wish to simply top-up the refrigerant,
bear in mind that there may be a slight drop in unit performance. In all
cases the top-up must be carried out in the low pressure section of the
machine before the evaporator, using the pressure sockets. Make sure
that the refrigerant is introduced only in the liquid phase.
Restoring compressor oil level
With the unit switched off, the oil level in the compressors must partially
cover the sight-glass on the level matching tube. The level is not always
constant as it depends on the ambient temperature and the percentage
of refrigerant in the oil. With the unit on and in nominal conditions the
oil level should be clearly visible through the sight-glass and must be
evacuating the compressors, using the pressure connection on the
intake. For information on the amount and type of oil, refer to the label
on the compressor or contact a RHOSS service centre.
Repairing and replacing components
Always refer to the wiring diagrams enclosed with the appliance when
replacing electrically powered components. Always take care to cle-
arly label each wire before disconnecting, in order to avoid making
mistakes later when re-connecting.
When the machine is started up again, always go through the recom-
mended start-up procedure.
After maintenance has been performed on the unit, the liquid-humidity
indicator (LUE) must be under control. After at least 12 hours of run-
ning, the refrigeration circuit of the unit must be perfectly "dry", with
Once the cartridges has been replaced, evacuate the circuit again
to eliminate any trace of non-condensable gases, which could have
that there are no gas leaks before restarting the machine for normal
working.
Instructions on how to drain the cooling circuit
In order to drain the cooling circuit completely by means of type-
approved devices, drain the refrigerant from both the high and low-
pressure sides and in the liquid line. Use the load connections in every
discharged into the atmosphere as it causes pollution. It should be
recovered in suitable cylinders and delivered to a company authorised
for the collection.

Eliminating Circuit Humidity
If during the operation of the machine there is evidence of humidity in
the refrigerant circuits, it is essential to drain the circuit completely of
refrigerant and eliminate the cause of the problem. To remove all the
humidity, the operator must dry out the circuit by evacuating it to 70 Pa,
and then proceed to recharge it with the gas charge indicated in the
plate located on the unit.

DISMANTLING THE UNIT

SAFEGUARD THE ENVIRONMENT
Dispose of the packaging materials in compliance with the national or local le-
gislation in force in your country. Do not leave the packaging within reach of
children.
It is advisable that the dismantling of the unit is performed by a company
authorised to collect obsolete products and machinery. The unit as a
whole is composed of materials considered as secondary raw materials
and the following conditions must be complied with:
the compressor oil must be removed, recovered and delivered to a
facility authorized to collect waste oil;
refrigerant gas may not be discharged into the atmosphere. It should in-
stead be recovered by means of homologated devices, stored in suita-
ble cylinders and delivered to a company authorised for the collection;
are considered special waste, and must be delivered to a body autho-
rized to collect such items;
the expanded polyurethane rubber insulation of the water exchanger
and the sound-absorbent sponge lining the bodywork must be removed
and processed as urban waste.
