HOMCOM 823-039V70CW Assembly Instruction Manual page 4

● Never use sources of ignition when searching for refrigerant leaks. Do not
use a halide torch (or any other naked flame).
● For leak detection, the use of detergents containing chlorine must be
avoided.
● If a leak is suspected, all naked flames shall be removed/extinguished.
● Call the service agent immediately and keep far away from the product.
● If disposal is needed, please contact the service agent or authorised
personnel to do it. Do not dispose the product yourself.
● Install the appliance in accordance with national wiring regulations.
● The maximum refrigerant charge amount: 200g.
● Keep the appliance in a ventilated area. If there is a refrigerant leak, there is
less likely of a explosion or fire hazard happening.
● Check cords regularly, ensuring there is no damage, wear or corrosion.
● The following leak detection methods are deemed acceptable for systems
containing flammable refrigerants.
● Electronic leak detectors shall be used to detect flammable refrigerants, but
the sensitivity may not be adequate or may need recalibration (detection
equipment shall be calibrated in a refrigerant-free area).
● Ensure the detector is not a potential source of ignition and is suitable for the
refrigerant used.
● Leak detection equipment shall be set at a percentage of the LFL of the
refrigerant and shall be calibrated to the refrigerant employed and the
appropriate percentage of gas (25% maximum) is confirmed.
● Leak detection fluids are suitable for use with most refrigerants, but the use
of detergents containing chlorine shall be avoided as the chlorine may react
with the refrigerant and corrode the copper pipe.
● If a leakage is found which requires brazing, all of the refrigerant shall be
recovered from the system, or isolated (by shutting off valves).
● Oxygen free nitrogen (OFN) shall then be purged through the system both
before and during the brazing process.
● Before carrying out this procedure, it is essential that the technician is
completely familiar with the equipment and all its detail. It is recommended
that all refrigerants are recovered safely. Prior to the task being carried out,
an oil and refrigerant sample shall be taken, in case analysis is required
before reusing the reclaimed refrigerant. It is essential that electrical power
is available before the task is commenced.
● Become familiar with the equipment and its operation.
● Isolate system electrically.
● Before attempting the procedure, ensure that:
– Mechanical handling equipment is available, if required, for handling
refrigerant cylinders.
– All personal protective equipment is available and being used correctly.
– The recovery process is supervised at all times by a competent adult.
– Recovery equipment and cylinders conform to the appropriate standards.
