SPECIAL PRECAUTIONS
WARNING When Wiring
●
Do not supply power to the unit until
all wiring and tubing are completed or
reconnected and checked.
Highly dangerous electrical voltages are
●
used in this system.
Carefully refer to the wiring diagram and
these instructions when wiring. Improper
connections and inadequate grounding
can cause accidental injury or death.
Connect all wiring tightly. Loose wiring
●
may cause overheating at connection
points and a possible fire hazard.
Provide a power outlet to be used exclu-
●
sively for each unit.
practice which can result in severe
personal injury or death.

practice which can result in personal injury
or product or property damage.
ELECTRICAL SHOCK CAN

INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD
ATTEMPT TO WIRE THIS
SYSTEM.
CZ-PXXXHR2U
(Single type)
●
Provide a power outlet exclusively for
each unit, and full disconnection means
having a contact separation in all poles
must be incorporated in the fixed wiring
in accordance with the wiring rules.
To prevent possible hazards from
●
insulation failure, the unit must be
grounded.
This equipment is strongly recommended
●
to be installed with Earth Leakage
Circuit Breaker (ELCB) or Residual
Current Device (RCD). Otherwise, it may
cause electrical shock and fire in case
of equipment breakdown or insulation
breakdown.
When Transporting
Be careful when picking up and moving
the units. Get a partner to help, and bend
your knees when lifting to reduce strain on
your back. Sharp edges on the solenoid
valve kit can cut your fingers.
When Installing…
Select an installation location which is
rigid and strong enough to support or hold
the unit, and select a location for easy
maintenance.
…In a Room
●●Properly insulate any tubing run inside a
room to prevent “sweating” that can
cause dripping and water damage to
walls and floors.
The solenoid valve kit produces some
refrigerant noise. If it is to be installed in
a quiet place such as a hospital, library
or hotel, it is strongly recommended that
the solenoid valve kit be installed in the
ceiling of a corridor, etc. apart from the
room.
Keep the fire alarm and
CAUTION
the air outlet at least
4.9 ft (1.5 m) away from the
unit.

When Connecting Refrigerant Tubing
Pay particular attention to refrigerant
leakages.
CAUTION
●
When performing piping work, do
not mix air except for specified
refrigerant (R410A) 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 except the tubing between
solenoid valve kit and indoor unit.
It is strongly recommended that the
solenoid valve kit be installed in the
ceiling of a corridor, etc. apart from the
room.
●
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.
WARNING
This product must not be
●
modified or disassembled under any
circumstances. Modified or
disassembled unit may cause fire,
electric shock or injury.
●
Do not clean inside the indoor and
outdoor units by users. Engage
authorized dealer or specialist for
cleaning.
●
In case of malfunction of this
appliance, do not repair by yourself.
Contact the sales dealer or service
dealer for repair.
CAUTION
●●Ventilate any enclosed areas when
installing or testing the refrigeration
system. Leaked refrigerant gas, on
contact with fire or heat, can produce
dangerous toxic gas.
Confirm after installation that no
refrigerant gas is leaking. If the gas
comes in contact with a burning
stove, gas water heater, electric room
heater or other heat source, it can
cause the generation of poisonous
gas.
Others
CAUTION
● Do not sit or step on the unit, you
may fall down accidentally.
When Servicing
●
Turn the power OFF at the main
power box (mains) before opening
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
chips or bits of wiring have been left
inside the unit.
