GRE HPM20 Manual De Instrucciones página 9

 use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the information plate,
 the test pressure for both the high and low pressure circuits must not exceed 42 bar in cases
where the appliance is equipped with the optional pressure gauge.
 The high pressure circuit pipes are made of copper and have a diameter equal to or greater than 1''5/8. A
certificate as indicated in §2.1 in compliance with standard NF EN 10204 must be requested from the
supplier and filed in the installation's technical file.
 Technical data relative to the safety requirements of the various applicable directives are indicated on the
information plate. All this information must be recorded in the appliance's installation manual, which must
be kept in its technical file: model, code, serial number, maximum and minimum OT, OP, year of
manufacture, CE marking, manufacturer's address, refrigerant and weight, electrical parameters, thermo-
dynamic and acoustic performance.
LABELLING
 The equipment must be labelled so as to specify that it is out of order and that the refrigerant has been
drained.
 The label must be dated and signed.
 For appliances containing a flammable refrigerant, check that labels are placed on the equipment stating
that it contains a flammable refrigerant.
RECOVERY
 When draining the refrigerant for maintenance or decommissioning, best practices should be followed in
order to safely drain all of the refrigerant.
 When transferring refrigerant to a cylinder, make sure that you use a recovery cylinder that is compatible
with the refrigerant. Make sure that the correct number of cylinders are provided for recovering all of the
refrigerant. All cylinders used must be intended for the recovery of refrigerant and must be labelled for this
specific refrigerant. The cylinders must be equipped with a vacuum valve and a stop gate in good working
order. Empty collection cylinders are drained and, where possible, cooled before recovery.
 The recovery equipment must be in good working order, the instructions for using the equipment must be
within reach and the equipment must be compatible for use with the refrigerant concerned, including,
where appropriate, a flammable refrigerant. Moreover, a set of calibrated scales must be available and in
good working order. The pipework must be complete, have no leaks or disconnected connectors, and must
be in good condition. Before using the recovery unit, check that it is in good working order, that it has been
well maintained and that the associated electric components are sealed so as to prevent any risk of fire in
the event of refrigerant being released. If you have any doubts, contact the manufacturer.
 The recovered refrigerant must be sent to the refrigerant supplier in its recovery cylinder with a waste
transfer note. Do not mix different refrigerants in the recovery units, and in particular in the cylinders.
 If the compressor has been removed or if oil from the compressor has been drained, check that the
refrigerant has been completely removed to prevent it from mixing with the lubricant. The draining process
must be carried out before returning the compressor to the supplier. Only the electric heater of the
compressor body can be used to accelerate this process. This operation can be carried out safely once all
liquids within the system have been drained.
RECYCLING
This symbol is required by the European directive DEEE 2012/19/EU (directive on
waste electrical and electronic equipment) and means that your appliance must not
be thrown into a normal bin. It will be selectively collected for the purpose of reuse,
recycling or transformation. If it contains any substances that may be harmful to the
environment, these will be eliminated or neutralised. Contact your retailer for
recycling information.
