Leak detection
• Do not use any kind of flame to detect refrigerant leakage.
• Use electric detectors only if sure of their efficiency and
safety in an explosive environment; for this purpose the in-
strument must be able to detect an R290 leak equivalent to
a maximum of 25% of the LFL (Lower Flammability Level).
• Alternatively, specific leak detector sprays can be used for
refrigerant gases; the product used must be non-corrosive
type.
In order to be used safely, the leak detection instruments must
have a calibration tool normally called a calibrated leak. Check-
ing the sensitivity of the detector with the aid of the calibration
tool must be carried out far from the place of installation in
order to ensurer correct calibration.

containing HC type gases
such as R290 (Propane).
This equipment contains 0.15 kg
of flammable gas (Propane R290).
Carefully read the warnings indi-
R290
cated in chapter 8 on page 148.
At the end of use, the heat pumps must be disposed of in com-
pliance with current regulations.
Divide the materials and dispose
of them in special collection cen-
tres suitable for waste disposal,
ATTENTION
according to the laws and regu-
lations in force in the country of
use.
Disposal operations must only be carried out at an authorised
centre by qualified personnel and in full compliance with cur-
rent regulations.

Before proceeding with the disposal of the product, it is nec-
essary to safely remove the refrigerant gas from the circuit;
this operation must be performed according to the following
procedure:
• The product must not be connected to the power grid.
• Before starting, ensure you have an adequate gas recovery
system equipped with cylinders suitable for the quantity and
type of gas you are about to recover, make sure you are
wearing suitable PPE.
• Empty the circuit from the pipe used by the manufacturer
to charge the refrigerant gas and at the same time from the
compressor suction pipe.
• Start the refrigerant gas recovery system, taking care not to
exceed more than 80% in filling and in the maximum oper-
ating pressure.
• The operation ends when the desired vacuum level has been
reached; at this point close the recovery cylinder valves and
remove the device.
• The removed gas can only be reused after it has been puri-
fied and checked by its supplier.
Product disposal label
The product must be identified with a label indicating that it
must be scrapped, bearing the date and signature of the em-
ployee in charge.
The label must indicate that the product contains a flammable
gas.
Recovery of refrigerant gas
To perform this operation, the recovery equipment used must
be in full working order and properly maintained, suitable for
use with flammable gases and accompanied by an instruction
manual for proper use.
The connecting pipes must be in good condition and equipped
with leak-free connections.
The recovery cylinders must be suitable for use and equipped
with a safety valve and shut-off valve, if possible, cool the cyl-
inders before carrying out the recovery operation.
The refrigerant gas recovered must be correctly identified and
not mixed with other different gases within the same cylinder;
the cylinders must then be sent to the gas supplier who will
perform recovery and purification.
If it is necessary to dispose of the compressor or the oil con-
tained in it, it is advisable to first provide for the electrical heat-
ing of the compressor body in order to allow the complete
and quick evaporation of the refrigerant gas that may have
remained dissolved in the oil. The oil must then be managed
appropriately.
