PAR-W21MAA

Installation Manual

This instruction manual describes how to install the Remote Controller for CITY MULTI R410A SERIES HOT WATER SUPPLY, AIR TO WATER, and FLOW TEMP. CONTROLLER. Please read this manual thoroughly and install the remote controller accordingly. For information on how to wire and install CITY MULTI R410A SERIES HOT WATER SUPPLY, AIR TO WATER, and FLOW TEMP. CONTROLLER Remote Controller, refer to the installation manual. After the installation, hand over this manual to users.

1 Safety Precautions

● Read these Safety Precautions and perform installation work accordingly.

● The following two symbols are used to dangers that may be caused by incorrect use and their degree:

WARNING

CAUTION

● After reading this installation manual, give it and units installation manual to the end user.

● The end user should keep this manual and units installation manual in a place where he or she can see it at anytime. When someone moves or

repairs the PAR-W21MAA, make sure that this manual is forwarded to the end user.

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-W21MAA.

Any lack of strength may cause the PAR-W21MAA 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-W21MAA 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-W21MAA 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 component parts.

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

Inverters, emergency power supply generators, high-frequency medical equipment, and wireless communication equipment can cause the remote controller 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.

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 install in any place at a temperature of more than 40°C [104°F] or less than 0°C [32°F] or exposed to direct sunlight.

Doing so may cause deformation or malfunction.

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. Cross recessed pan head screw (M4 × 30) ............................................................... 2

3. Wood screw (4.1 × 16, used for directly hooking to the wall) .................................... 2

4. Caution label (in 16 languages) ................................................................................. 1

Use the cable specified in the Installation Manual that comes with the units for remote controllers.

This symbol denotes what could lead to serious injury or death if you misuse the PAR-W21MAA.

This symbol denotes what could lead to a personal injury or damage to your property if you misuse the PAR-W21MAA.

WARNING

Ensure that installation work is done correctly following this installation manual.

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

All electrical work must be performed by a licensed technician, according 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-W21MAA 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.

CAUTION

Do not apply AC100V or AC200V to the remote controller. The maximum voltage that can be applied to the remote controller is 12V.

The remote controller may be damaged or may generate heat and cause a fire.

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.

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 control button with your wet hands.

Doing so 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 press any control button using a sharp object.

Doing so may cause an electric shock or a malfunction.

Remote controller cover

Remote controller body

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

NOTE: - Choose 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.

To the remote controller

CAUTION

terminal block on the unit

There is no polarity.

Do not use crimp terminals to connect to remote controller terminal blocks. The terminals may contact the board and cause trouble or contact the cover and damage the cover.

To connect the remote control cord, peel 6mm

[

/4 in] of coating.

CAUTION Prevent remote cord chips from getting into the remote controller. Electric shock or malfunction may result.

6. 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.

7. Install the cover to the remote controller.

To remove the cover, insert a minus screwdriver into one of the open slots, and move it in the direction of the arrow shown in the figure.

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.

CAUTION

Do not turn into the screwdriver in the slot. Doing so may damage the slot.

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

2. Seal the remote controller cord with putty in order to prevent the possible entry of dew, water droplets, cockroaches, other insects, etc.

When using the switch box

• When installing on the switch box, seal the connections between the switch box and wiring pipe with putty.

When installing directly on the wall

• When opening a hole using a drill for the remote controller cord (or when taking the cord out of the back of the remote controller), seal the hole with putty.

• When routing the cord via the portion cut off from the upper cover, similarly seal that portion with putty.

• When taking the remote controller cord from back of the controller, use surface raceways.
