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.
• 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.
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.
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.
• The user should never attempt to repair the unit or transfer it to another loca-
tion.
• The appliance shall be installed in accordance with national wiring regula-
tions.
• If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
• 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.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other
hazards.
The 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.
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.
• 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.
• If the unit is run for long hours when the air above the ceiling is at high tem-
perature/high humidity (dew point above 26 ºC), dew condensation may be
produced in the indoor unit or the ceiling materials. When operating the units
in this condition, add insulation material (10-20 mm) to the entire surface of
the unit and ceiling materials to avoid dew condensation.
2. Selecting the installation location
2.1. 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).
• 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.
2.2. Wireless remote controller mounting
(For SLZ-KA·VAL3)
• 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.
In rooms where inverter type fluorescent lamps are used, the signal from the
wireless remote controller may not be received.
Note:
The phrase “Wired remote controller” in this installation manual refers only to the PAR-32MAA. 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.

4.4. Suspension structure (Give site of suspension
strong structure) (Fig. 4-4)
• The ceiling work differs according to the construction of the building. Building con-
structors and interior decorators should be consulted for details.
(1) Extent of ceiling removal: The ceiling must be kept completely horizontal and the
ceiling foundation (framework: wooden slats and slat holders) must be reinforced
in order to protect the ceiling from vibration.
(2) Cut and remove the ceiling foundation.
(3) Reinforce the ends of the ceiling foundation where it has been cut and add ceiling
foundation for securing the ends of the ceiling board.
(4) When installing the unit on a slanting ceiling, interlock a pillow between the ceiling
and the grille and set so that the unit is installed horizontally.
1Wooden structures
• Use tie beams (single-story houses) or second floor beams (two story houses) as
reinforcing members.
• Wooden beams for suspending air conditioners must be sturdy and their sides must
be at least 6 cm long if the beams are separated by not more than 90 cm and their
sides must be at least 9 cm long if the beams are separated by as much as 180
cm. The size of the suspension bolts should be ø10 (3/8"). (The bolts do not come
with the unit.)

4.5. Unit suspension procedures (Fig. 4-5)
Suspend the main unit as shown in the diagram.
1. In advance, set the parts onto the suspension bolts in the order of the washers
(with insulation), washers (without insulation) and nuts (double).
• Fit the washer with cushion so that the insulation faces downward.
• In case of using upper washers to suspend the main unit, the lower washers (with
insulation) and nuts (double) are to be set later.
2. Lift the unit to the proper height of the suspension bolts to insert the mounting
plate between washers and then fasten it securely.
3. When the main unit can not be aligned against the mounting hole on the ceiling,
it is adjustable owing to a slot provided on the mounting plate. (Fig. 4-6)
• Make sure that step A is performed within 27-32 mm. Damage could result by
failing to adhere to this range.
4.6. Confirming the position of main unit and tightening
the suspension bolts (Fig. 4-7)
• Using the gauge attached to the grille, ensure that the bottom of the main unit is
properly aligned with the opening of the ceiling. Be sure to confirm this, otherwise
condensation may form and drip due to air leakage etc.
• Confirm that the main unit is horizontally levelled, using a level or a vinyl tube filled
with water.
• After checking the position of the main unit, tighten the nuts of the suspension bolts
securely to fasten the main unit.
• The installation template can be used as a protective sheet to prevent dust from
entering the main unit when the grilles are left unattached for a while or when the
ceiling materials are to be lined after installation of the unit is finished.
* As for the details of fitting, refer to the instructions given on the Installation template.

5. Refrigerant piping work
5.4. Pipe connection (Fig. 5-8)
Indoor unit
1) When using commercially available copper pipes:
• Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening
flare nut.
• Use two wrenches to tighten piping connections.
• Air-purge the refrigerant piping using your own refrigerant gas (don’t air-purge the
refrigerant charged in the outdoor unit).
• Use leak detector or soapy water to check for gas leaks after connections are
completed.
• Use refrigerant piping insulation provided to insulate indoor unit connections. Insulate
carefully following shown below.
2) Heat insulation for refrigerant pipes:
1Wrap the enclosed large-sized pipe cover around the gas pipe, making sure that
the end of the pipe cover touches the side of the unit.
2Wrap the enclosed small-sized pipe cover around the liquid pipe, making sure that
the end of the pipe cover touches the side of the unit.
3Secure both ends of each pipe cover with the enclosed bands. (Attach the bands
20 mm from the ends of the pipe cover.)
See that stop valve on outdoor unit is fully shut (unit is shipped with valve shut).
After all piping connections between indoor and outdoor unit have been completed,
vacuum-purge air from system through the service port for the stop valve on the
outdoor unit.
After completing procedures above, open outdoor unit stop valves stem fully. This
completes connection of refrigerant circuit between indoor and outdoor units. Stop
valve instructions are marked on outdoor unit.
• Apply a thin coat of refrigeration oil on the seat surface of pipe. (Fig. 5-9)
• For connection first align the center, then tighten the first 3 to 4 turns of flare nut.
• Use tightening torque table below as a guideline for indoor unit side union joint
section, and tighten using two wrenches. Excessive tightening damages the flare
section.
