Mitsubishi Electric PAR-FA32MA Installation Manual

Building Air Conditioning Control System
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 " 1 Safety Precautions " described below thoroughly and then install the Signal Receiving Unit PAR-
FA32MA correctly.
1 Safety Precautions
● The following two symbols are used to denote dangers that may be caused by incorrect use and their degree:
WARNING
This symbol denotes what could lead to serious injury or death if you misuse the PAR-FA32MA.
CAUTION
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 elec-
tric 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, re-
sulting 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.
■ 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.
2 Confirming the Supplied Parts

2-2 When setting in different rooms.
Assing a different number to each wireless remote
controller and all the Signal Receiving Unit
(Leave the setting as purchase)
(2) Main/Sub switch settings (leave the initial "Main" setting when not using the MA remote controller).
Set the Main/Sub switch when using with the MA remote controller (PAR-20MAA).
Set the signal receiving unit to "Sub" and the MA remote controller (PAR-20MAA) to "Main".
5 How To Install
(1) Choose a place in which to install the Signal Receiving Unit (switch box).
Be sure to observe the following steps:
1 When installing on either the switch box or the wall,allow space around the Signal
Receiving Unit as shown in the figure on the right.
2 When installing the Signal Receiving Unit to the swich box, the Signal Receiving Unit
slipped downward for 6.5 mm (1/4 inch) as right illustrated.
3 Parts which must be supplied on site.
Switch box for one unit
Thin-copper wiring pipe
Lock nut and bushing
4 lnstall the unit on the wall or ceiling where the signal is received from the remote
controller.
(Refer to the below illustration)
90˚
Install the Signal Receiving Unit where is watched from any position.
NOTE: lf the Signal Receiving Unit is installed near a fluoresent lamp specially inverter type,signal interception may occur.
Be careful for installing the Signal Receiving Unit or replacing the lamp.
(2) Install the remote control cord to the terminal block (No polarity).
Remote control cord
Insert the minus screwdriver toward the
arrow pointed and wrench it to remove the cover.
A flat screwdriver whose width of blade is between
4 and 7 mm (5/32 - 9/32 inch) must be used.

■ 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 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 termi-
nals.
Doing so will certainly cause the controller to catch fire.
