How To Install

1.

Chose a place in which to install the remote controller (switch box).

Be sure to observe the following steps:
(1) Temperature sensors are provided with both the remote controller and the indoor units. When using the

remote controller temperature sensor, the master remote controller detects the room temperature.
Install the master remote controller in a place where the average room temperature can be detected
and which is not affected by any heat source from direct sunlight or air blown from air conditioning units.
(For how to set the master and subordinate remote controller, see step 6 in section    4   How To Install .
For how to set the temperature sensor, refer to the CITY MULTI indoor unit installation manual.)

(2) When installing on either the switch box or the wall, allow extra space around the remote controller as

shown in the figure at the right.
(When using the remote controller in combination with a Program timer, refer to the Program timer
installation manual.)

NOTE: Make sure that there is no wiring or wire near the remote controller sensor. If there is, the remote controller cannot detect the exact room

temperature.

(3) Parts which must be supplied on site.

• Switch box for two units
• Thin-copper wiring pipe
• Lock nut and bushing

2

Confirming the Supplied Parts

Confirm that the box includes the following parts, in addition to this installation manual:

1. Remote controller (cover, body) ..................................................................................... 1
2. Remote control cord (10 m) ............................................................................................ 1
3. Cross recessed pan head screw (M4 

×

 30) .................................................................... 2

4. Wood screw (4.1 

×

 16, used for directly hooking to the wall) ......................................... 2

5. Instruction book .............................................................................................................. 1
6. Caution label (in 10 languages) ...................................................................................... 1

6

Group registration and interlocked registration

CAUTION Do not tighten the screws too tight. Doing so may deform or crack the lower cover.

NOTE: - Chose a flat plane for installation.

- Fasten the switch box at more than two places when installing directly on the wall.
- When reinstalling on the wall, fasten securely using anchors.

5.

Connect the remote control cord to the remote controller terminal block.

CAUTION

Do not use crimp terminals to connect to the remote controller terminal block. To do so may cause the terminals to touch the
board and cause trouble at the remote controller. If the terminals touch the cover, the cover may be damaged.

6.

Set the remote controller address using the rotary switches.

7.

Wiring hole for installing directly on the wall (or open wiring)

• Cut off the shaded area from the upper cover using a knife, nippers, etc.
• Take out the remote control cord connected to the terminal block via this portion.

8.

Install the cover to the remote controller.

First, hook the cover to the two upper claws and then fit it to the remote controller.

CAUTION  Press the cover until it snaps shut. If not, it may fall off.

NOTE: A protection sheet is stuck to the operation section. Peel off this protection sheet before use.

How To Connect Optional Parts

The extrior design for PAC-SC32PTA (Program timer) is different from the one for PAR-F27MEA.

When connecting a Program timer, connect a 5-core cable to the connector on the remote controller. (A
5-core cable is supplied with the Program timer.)

To route the cable, cut off the thin-wall portion.

For wiring path convenience, install the Program timer to the left-hand side of the remote controller.
When expansion is expected, take into consideration remote controller space at the left-hand side.
For the operation method details, refer to the Program timer installation manual.

Use standard wires in compliance with the current capacity.

A failure to this may result in an electric leakage, heating or fire.

Do not touch any PCB (Printed Circuit Board) with your hands or with
tools. Do not allow dust to collect on the PCB.

Doing so may cause fire or an electric shock.

Do not remove the insulation sheet on the PCB.

Doing so may cause an electric shock.

Do not touch any control button with your wet hands.

Doing so may cause an electric shock or a malfunction.

Do not press any control button using a sharp object.

Doing so may cause an electric shock or a malfunction.

Never contact the power supply with the control wiring terminals.

Doing so will certainly cause the controller to catch fire.

When installing the remote controller in a hospital or communication
facility, take ample countermeasures against noise.

Inverters, emergency power supply generators, high-frequency medical equip-
ment, and wireless communication equipment can cause the remote control-
ler to malfunction or to fail. Radiation from the remote controller may effect
communication equipment and prevent medial operations on the human body
or interfere with image transmission and cause noise.

Ask your dealer or technical representative to install the unit.

Any deficiency caused by your own installation may result in an electric shock
or fire.

Install in a place which is strong enough to withstand the weight of the
PAR-F27MEA.

Any lack of strength may cause the PAR-F27MEA to fall down, resulting in
personal injury.

Firmly connect the wiring using the specified cables. Carefully check
that the cables do not exert any force on the terminals.

Improper wiring connections may produce heat and possibly a fire.

Never modify or repair the PAR-F27MEA by yourself.

Any deficiency caused by your modification or repair may result in an electric
shock or fire.
Consult with your dealer about repairs.

Do not install in any place exposed to flammable gas leakage.

Flammable gases accumulated around the body of PAR-F27MEA may cause
an explosion.

Do not use in any special environment.

Using in any place exposed to oil (including machine oil), steam and sulfuric
gas may deteriorate the performance significantly or give damage to the com-
ponent parts.

Wire so that it does not receive any tension.

Tension may cause wire breakage, heating or fire.

Completely seal the wire lead-in port with putty etc.

Any dew, moisture, insects entering the unit may cause an electric shock or a
malfunction.

Do not wash with water.

Doing so may cause an electric shock or a malfunction.

Do not install in any place at a temperature of more than 40

°

C or less

than 0

°

C or exposed to direct sunlight.

Do not install in any steamy place such a bathroom or kitchen.

Avoid any place where moisture is condensed into dew. Doing so may cause
an electric shock or a malfunction.

Do not install in any place where acidic or alkaline solution or special
spray are often used.

Doing so may cause an electric shock or malfunction.

Ensure that installation work is done correctly following this installa-
tion manual.

Any deficiency caused by installation may result in an electric shock or fire.

All electrical work must be performed by a licensed technician, accord-
ing to local regulations and the instructions given in this manual.

Any lack of electric circuit or any deficiency caused by installation may result
in an electric shock or fire.

Do not move and re-install the PAR-F27MEA yourself.

Any deficiency caused by installation may result in an electric shock or fire.
Ask your distributor or special vendor for moving and installation.

To dispose of this product, consult your dealer.
