VRV 5 safety valve unit

▪ In case of accidental refrigerant
leaks, make sure there are no naked
flames. The refrigerant itself is
entirely safe, non-toxic and mildly
flammable, but it will generate toxic
gas when it accidentally leaks into a
room where combustible air from fan
heaters, gas cookers, etc. is present.
Always have qualified service
personnel confirm that the point of
leakage has been repaired or
corrected before resuming operation.
WARNING
This unit contains electrical and hot
parts.
WARNING
Before operating the unit, be sure the
installation has been carried out
correctly by an installer.
WARNING
Do NOT obstruct the opening of the air
inlet (damper).
WARNING
The unit is equipped with a refrigerant
leak detection system for safety.
To be effective, the unit MUST be
electrically powered at all times after
installation, except for short service
periods.
Maintenance and service (see "6Maintenance and
service"[410])

leak detection system for safety.
To be effective, the unit MUST be
electrically powered at all times after

NEVER replace a fuse with a fuse of a
wrong ampere ratings or other wires
when a fuse blows out. Use of wire or
copper wire may cause the unit to

be replaced by the manufacturer, its
service agent or similarly qualified
persons in order to avoid a hazard.

About the refrigerant (see "6.2About the refrigerant"[410])
WARNING
▪ Do NOT pierce or burn refrigerant
cycle parts.
▪ Do NOT use cleaning materials or
means to accelerate the defrosting
process other than those
recommended by the manufacturer.
▪ Be aware that the refrigerant inside
the system is odourless.
WARNING
▪ The refrigerant inside the unit is
mildly flammable, but normally does
NOT leak. If the refrigerant leaks in
the room and comes in contact with
fire from a burner, a heater, or a
cooker, this may result in fire, or the
formation of a harmful gas.
▪ Turn OFF any combustible heating
devices, ventilate the room, and
contact the dealer where you
purchased the unit.
▪ Do NOT use the unit until a service
person confirms that the part from
which the refrigerant leaked has been
repaired.
