Signal Receiving Unit PAR-FA32MA

Installation Manual

This installation manual contains only the description of how to install the Signal Receiving Unit PAR-FA32MA. For information about how to wire and how to install air conditioning units, see the installation manual for them. For your safety, first be sure to read FA32MA correctly.

1 Safety Precautions

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

“ 1 Safety Precautions ”

described below thoroughly and then install the Signal Receiving Unit PAR-

WARNING CAUTION

This symbol denotes what could lead to serious injury or death if you misuse the PAR-FA32MA.

This symbol denotes what could lead to a personal injury or damage to your property if you misuse the PAR-FA32MA.

● After reading this installation manual, keep it in a place where the final user can see it anytime. When someone moves, repairs or uses the PAR-FA32MA, make sure that this manual is forwarded to the final user.

WARNING

■ 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-FA32MA.

Any lack of strength may cause the PAR-FA32MA 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-FA32MA by yourself.

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

■ 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-FA32MA 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 install in any place exposed to flammable gas leakage.

Flammable gases accumulated around the body of PAR-FA32MA 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.

■ 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, cockroaches, 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 (104 °F) or less than 0 °C (32 °F) 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.

■ 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 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.

2 Confirming the Supplied Parts

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

(1) Signal Receiving Unit ......................................................... 1

(2) Remote control cord (2 core 3 m (9 ft)) .............................. 1

NOTE:

Extended remote controller cords are not supplied with this equipment and must therefore be procured locally by the customer. Use electrical cable in accordance with the following specifications.

NOTE:

• No power supply lines are shown and only the transmission lines are shown in the above wiring example.

• Provide shield grounding of M-NET transmission line at one arbitrary point.

(Main) (Sub)

Group 4

A main remote controller and a sub remote controller can be connected to each group.

1 Wiring from signal receiving unit.

· Connected to MA remote controller wiring terminal block (TB15) on the indoor unit. (The terminal block has no polarities.)

2 With group operation (group 3 and group 4 above).

· After wiring the MA remote controller wiring terminal block (TB15) on the group operation indoor unit, connect to the indoor unit

with the lowest address within the group.

NOTE: With group operation with a different cooling system, wire only the MA remote controller wiring terminal block (TB15).

Do not wire the indoor/outdoor transmission terminal block (TB5).

3 The signal receiving unit and the MA remote controller may be used together (group 4 above).

· Set the MA remote controller as “Main”, and the signal receiving unit as “Sub”.

· When other types of remote controllers are used, refer to section “ 7 Possible Combinations of Signal Receiving Units and

Remote Controllers ”.

∗ See the installation manual supplied with the outdoor unit for details of setting up indoor (IC) and outdoor (OC) units. ∗ See the relevant equipment manual for details of setting up the central controller and transmission line power supply unit.
