This manual describes the installation of the PAC-SF46EPA Transmission Booster and the air conditioner units. For the information
about how to install the central controller or the air conditioner 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 PAC-SF46EPA correctly.
After reading this installation manual, keep it in a location that is easy to find. If the PAC-SF46EPA Transmission Booster is going to
be operated by another person, make sure that this manual is given to them.
1 Safety Precautions
Before installing this unit, make sure you read all the “Safety Precautions”.
The “Safety Precautions” provide very important points regarding safety. Make sure you follow them.
Symbols and Terms
Specific Precautions
WARNING Statements identify condition or practices that could result in personal injury or loss of life.
CAUTION Statements identify condition or practices that could result in damage to the unit or other property.
WARNING
CAUTION
Ask your dealer or technical representative to install.
Any deficiency cased by your own installation may result in
an electric shock and fire.
Install in a place which is strong enough to withstand
the weight of the unit.
Any lack of the strength may cause the unit to fall down,
resulting in a personal injury.
Wire and connect using the desired cables securely so
that any external force exerted on the cable is not
imparted on to the terminal connections.
Imperfect connection and fixing may result in heating or fire.
Never modify or repair the unit by yourself.
Any deficiency caused by your modification or repair may
result in an electric shock or fire.
Consult with your distributor for repair.
Make sure that the unit is powered by a dedicated line.
Other appliances connected to the same line could cause
an overload.
Make sure that there is a main power switch.
A ready accessible breaker for power source line helps
reduce the risk of electric shocks. Installation of a breaker
is mandatory in same area.
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 unit yourself.
Any deficiency caused by installation may result in an
electric shock or fire.
Ask your distributor or special vender for moving and
installation.
This appliance must be earthed (grounded).
Make sure to install a protect earth (PE)/grounding line.
Do not connect the PE (grounding) line to gas or water
pipes, lightning conductors or telephone grounding lines.
Improper grounding may cause an electric shock.
Securely install the cover (panel) of the PAC-SF46EPA.
If the cover (panel) is not installed properly, dust or water
may enter the unit and fire or electric shock may result.
Do not install any place exposed to flammable gas
leakage.
Flammable gases that accumulates around the body of the
unit may caused an explosion.
Do not use in any special environment.
If use in any place exposed to oil (including machine oil),
steam and sulfuric gas may degrade performances
significantly or damage the component parts.
Wire so that it wires do not received any tension.
Tension may caused wire breakage, heating or fire.
Do not wash with water.
Doing so may cause an electric shock or 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.
Use only an earth leakage breaker and fuse of the
specified capacity.
If no earth leakage breaker is installed, it may cause an
electric shock.
Using fuse and wire or copper wire with too large a
capacity may cause a malfunction to the unit or fire.
Do not install in any steamy place such as bath room
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 or other similar substances
are used.
Doing so may cause an electric shock or malfunction.
Use standard wires in compliance with the current
capacity.
A failure to do this may result in an electric leakage,
heating or fire.
Do not touch any PCB (Printed Circuit Board) with your
hand or tools. Do not allow dust to collect on the PCB.
Doing so may cause fire or an electric shock.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction
concerning use of the appliance by a person responsible
for their safety. Children should be supervised to ensure
