d) recovery equipment and cylinders conform to the
appropriate standards.
4) Pump down refrigerant system, if possible.
5) If a vacuum is not possible, make a manifold so
that refrigerant can be removed from various parts of
the system.
6) Make sure that the cylinder is situated on the
scales before recovery takes place.
7) Start the recovery machine and operate in
accordance with instructions.
8) Do not overfill cylinders (no more than 80 %
volume liquid charge).
9) Do not exceed the maximum working pressure of
the cylinder, even temporarily.
10) When the cylinders have been filled correctly and
the process completed, make sure that the cylinders
and the equipment are removed from site promptly
and all isolation valves on the equipment are closed
off.
11) Recovered refrigerant shall not be charged into
another refrigerating system unless it has been
cleaned and checked.
Labelling
Equipment shall be labelled stating that it has been
de-commissioned and emptied of refrigerant. The
label shall be dated and signed. For appliances
containing flammable refrigerants, ensure that there
are labels on the equipment stating the equipment
contains flammable refrigerant.
Recovery
When removing refrigerant from a system, either for
servicing or decommissioning, it is required to follow
good practice so that all refrigerants are removed
safely.
When transferring refrigerant into cylinders, ensure
that only appropriate refrigerant recovery cylinders
are employed. Ensure that the correct number of
cylinders for holding the total system charge is
available. All cylinders to be used are designated for
the recovered refrigerant and labelled for that
refrigerant (i.e. special cylinders for the recovery of
refrigerant). Cylinders shall be complete with
pressure-relief valve and associated shut-off valves
in good working order. Empty recovery cylinders are
evacuated and, if possible, cooled before recovery
occurs.
The recovery equipment shall be in good working
order with a set of instructions concerning the
equipment that is at hand and shall be suitable for the
recovery of the flammable refrigerant. Consult
manufacturer if in doubt. In addition, a set of
calibrated weighing scales shall be available and in
good working order. Hoses shall be complete with
leak-free disconnect couplings and in good condition.
The recovered refrigerant shall be processed
according to local legislation in the correct
recovery cylinder, and the relevant waste transfer
note arranged. Do not mix refrigerants in recovery
units and especially not in cylinders.
If compressors or compressor oils are to be removed,
ensure that they have been evacuated to an
acceptable level to make certain that flammable
refrigerant does not remain within the lubricant. The
compressor body shall not be heated by an open
flame or other ignition sources to accelerate this
process. Draining of oil from a system shall be carried
out safely.
Intended use
There is a risk of injury or death to the user or others,
or of damage to the product and other property in the
event of improper or unintended use.
The product is the outdoor unit of an air-to-water heat
pump with monoblock design.
The product uses the outdoor air as a heat source
and can be used to heat a residential building and
generate domestic hot water.
The air that escapes from the product must be able to
flow out freely, and must not be used for any other
purposes.
The product is only intended for outdoor installation.
The product is intended exclusively for domestic use,
which means that the following places are not
appropriate for installation:
Where there is mist of mineral oil or oil spray or
vapors. Plastic parts may deteriorate, and cause joint
loose and leakage of water.
Where corrosive gases (such as sulfurous acid
gas) are produced, or corrosion of copper pipes or
soldered parts may cause leakage of refrigerant.
Where there is machinery which emits massive
electromagnetic waves. Enormous electromagnetic
waves can disturb the control of the system and
cause equipment malfunction.
Where flammable gases may leak, carbon fiber
or ignitable dust is suspended in the air or volatile
flammables such as paint thinner or gasoline are
handled. These types of gases might cause a fire.
Where the air contains high levels of salt such as
a location near the ocean.
Where voltage fluctuates a lot, such as a location
in a factory.
In vehicles or vessels.
Where acidic or alkaline vapors are present.
Intended use includes the following:
Observance
of
included for the product and any other installation
components.
Compliance with all inspection and maintenance
conditions listed in the instructions.
Installing
and
accordance with the product and system approval.
Installation, commissioning, inspection, maintenance
and troubleshooting by qualified contractors and
authorized installers.
