1. Safety Summary
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.
•
Disposal of equipment shall follow the national regulations.
•
The storage of the appliance should be in accordance with the applicable regulations or instructions,
whichever is more stringent.
•
The maximum number of pieces of equipment permitted to be stored together will be determined by
local regulations. Storage package protection should be constructed in such a way that mechanical
damage to the equipment inside the package will not cause a leak of the REFRIGERANT CHARGE.
CAUTION
!
•
Pay attention to the following points when the unit is installed in a hospital or other facilities where an
electromagnetic wave generates from a medical equipment.
○ Do not install the unit in the place where an electromagnetic wave is directly radiated to the electrical
box, remote control cable or remote control switch.
○ Install the unit at least 3 meters away from an electromagnetic wave such as a radio.
•
Do not install the unit in the place where the breeze directly catches animals and plants. It could
adversely affect animals and plants.
•
Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock.
•
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
•
Do not allow children to play on or around the unit to prevent injury.
•
Wear adequate personal protective equipment (protective gloves, safety glasses,...) when installing,
maintaining or servicing the system.
•
The heat exchanger fins are sharp enough to cut. To avoid injury, wear gloves or cover the fins while
working around them.
•
Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may
be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the
refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must
touch them, be sure to wear proper gloves.
