The phrase "Wired remote controller" in this installation manual refers only to the PAR-21MAA. If you need any information for the other remote controller,
please refer to either the installation manual or initial setting manual which are included in these boxes.
1. Safety precautions
• Be sure to read "Safety precautions" before installing the air conditioner.
• Be sure to observe the cautions specified here as they include important
items related to safety.
• The indications and meanings are as follows.
Warning:
Could lead to death, serious injury, etc.
Caution:
Could lead to serious injury in particular environments when operated incor-
rectly.
Warning:
• Do not install it by yourself (customer).
Incomplete installation could cause injury due to fire, electric shock, the unit
falling or leakage of water. Consult the dealer from whom you purchased the
unit or special installer.
• Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufficient strong place, the unit could fall causing
injured.
• Use the specified wires to connect the indoor and outdoor units securely and
attach the wires firmly to the terminal board connecting sections so the stress
of the wires is not applied to the sections.
Incomplete connecting and fixing could cause fire.
• Do not use intermediate connection of the power cord or the extension cord
and do not connect many devices to one AC outlet.
It could cause a fire or an electric shock due to defective contact, defective
insulation, exceeding the permissible current, etc.
• Check that the refrigerant gas does not leak after installation has completed.
• Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric
shock, the unit falling or leakage of water.
• Perform electrical work according to the installation manual and be sure to
use an exclusive circuit.
Caution:
• Perform grounding.
Do not connect the ground wire to a gas pipe, water pipe arrester or telephone
ground wire. Defective grounding could cause an electric shock.
• Do not install the unit in a place where an inflammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could cause
an explosion.
• Install a ground leakage breaker depending on the installation place (where
it is humid).
If a ground leakage breaker is not installed, it could cause an electric
shock.
. Selecting the installation location
.1. Indoor unit
• Where airflow is not blocked.
• Where cool air spreads over the entire room.
• Where it is not exposed to direct sunshine.
• At a distance 1 m or more away from your TV and radio (to prevent picture from
being distorted or noise from being generated).
• In a place as far away as possible from fluorescent and incandescent lights (so the
infrared remote control can operate the air conditioner normally).
2.2. Wireless remote controller mounting
(For SLZ-KA·VAL(2))
• Place of mounting
• Where it is easy to operate and easily visible.
• Where children can not touch.
• Mounting
Select a position about 1.2 m above the floor, check that signals from the remote
controller are surely received by the indoor unit from that position ('beep' or 'beep-
beep' receiving tone sounds). After that, attach remote controller holder to a pillar
or wall and set the wireless remote controller.

• After reading this manual, be sure to keep it together with the instruction
manual in a handy place on the customer's site.
: Indicates a part which must be grounded.
Warning:
Carefully read the labels affixed to the main unit.
If the capacity of the power circuit is insufficient or there is incomplete electri-
cal work, it could result in a fire or an electric shock.
• Attach the electrical part cover to the indoor unit and the service panel to the
outdoor unit securely.
If the electrical part cover in the indoor unit and/or the service panel in the
outdoor unit are not attached securely, it could result in a fire or an electric
shock due to dust, water, etc.
• Be sure to use the part provided or specified parts for the installation work.
The use of defective parts could cause an injury or leakage of water due to a
fire, an electric shock, the unit falling, etc.
• Ventilate the room if refrigerant leaks during operation.
If the refrigerant comes in contact with a flame, poisonous gases will be
released.
• When installing or relocating, or servicing the air conditioner, use only the
specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it with
any other refrigerant and do not allow air to remain in the lines.
I f air is mixed with the refrigerant, then it can be the cause of abnormal high pres-
sure in the refrigerant line, and may result in an explosion and other hazards.
T he use of any refrigerant other than that specified for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.
• Perform the drainage/piping work securely according to the installation
manual.
If there is a defect in the drainage/piping work, water could drop from the unit
and household goods could be wet and damaged.
• Fasten a flare nut with a torque wrench as specified in this manual.
When fastened too tight, a flare nut may broken after a long period and cause
a leakage of refrigerant.
• Where the air filter can be removed and replaced easily.
Warning:
Mount the indoor unit into a ceiling strong enough to withstand the weight of
the unit.
In rooms where inverter type fluorescent lamps are used, the signal from the
wireless remote controller may not be received.
