WARNING
• When performing piping work, do
not mix air except for specified
refrigerant in refrigeration cycle. It
causes capacity down, and risk of
explosion and injury due to high
tension inside the refrigerant cycle.
• If the refrigerant comes in contact
with a flame, it produces a toxic
gas.
• Do not add or replace refrigerant
other than specified type. It may
cause product damage, burst and
injury, etc.
• Ventilate the room immediately, in the
event that is refrigerant gas leaks during
the installation. Be careful not to allow
contact of the refrigerant gas with a
flame as this will cause the generation
of toxic gas.
• Keep all tubing runs as short as
possible.
• Use the flare method for connecting
tubing.
• Apply refrigerant lubricant to the
matching surfaces of the flare and union
tubes before connecting them, then
tighten the nut with a torque wrench for
a leak-free connection.
• Check carefully for leaks before starting
the test run.
• Do not leak refrigerant while piping work
for an installation or re-installation, and
while repairing refrigeration parts.
Handle liquid refrigerant carefully as it
may cause frostbite.
• Under no circumstances shall potential
sources of ignition be used in the
searching or detection of refrigerant
leaks.
• A halide torch (or any other detector
using a naked flame) shall not be used.
• Electronic leak detectors may be used
to detect refrigerant leaks but, the
sensitivity may not be adequate, or
may need re-calibration. (Detection
equipment shall be calibrated in a
refrigerant-free area.)
• Ensure that 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 lower flammable
limit (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-work.
• If a leak is suspected, all naked flames
shall be removed/extinguished.
• If a leakage of refrigerant is found which
requires brazing, all of the refrigerant
shall be recovered from the system, or
isolated (by means of shut off valves)
in a part of the system remote from the
leak. Oxygen free nitrogen (OFN) shall
then be purged through the system both
before and during the brazing process.
When Servicing
• Contact to the sales dealer or service
dealer for a repair.
• Be sure to turn off the power before
servicing.
• Turn the power OFF at the main
power box (mains), wait at least 10
minutes until it is discharged, then
open the unit to check or repair
electrical parts and wiring.
• Keep your fingers and clothing away
from any moving parts.
• Clean up the site after you finish,
remembering to check that no metal
scraps or bits of wiring have been left
inside the unit.
