1. FIRST OF ALL
• This document is an installation manual for the Daikin RTSYQ-P
Series VRV Inverter. Before installing the unit, read this manual
thoroughly, and following the instructions contained in it.
• After installation, do a test run to make sure the unit runs properly,
and then explain how to operate and take care of the unit to the
customer, using the operation manual.
• Lastly, make sure the customer keeps this manual, along with the
operation manual, in a safe place.
1-1 Safety precautions
Please read these “Safety precautions” carefully before installing air
conditioning unit and be sure to install it correctly.
Meaning of WARNING and CAUTION notices
Both are important notices for safety. Be sure to follow them.
Warning........Failure to follow these instructions properly may
result in personal injury or loss of life.
Caution.........Failure to observe these instructions properly
may result in property damage or personal
injury, which may be serious depending on the
circumstances.
After completing installation, conduct a test operation to confirm that
the equipment operates without any problems. Then, explain to the
customer how to operate the equipment and take care of it following
the operation manual.
Ask the customer to store the installation manual along with the oper-
ation manual for future reference.
Warning
•
Ask your dealer or qualified personnel to carry out installation work.
Do not attempt to install the air conditioner yourself. Improper
installation may result in water leakage, electric shocks or fire.
• Install the air conditioner in accordance with the instructions in
this installation manual.
Improper installation may result in water leakage, electric shocks or fire.
• When installing the unit in a small room, take measures so that
the refrigerant may not exceed the limiting concentration in the
event of refrigerant leakage.
Contact your dealer for further information. If the refrigerant leaks and
exceeds the limiting concentration, it may lead to oxygen deficiency.
• Be sure to use only the specified accessories and parts for instal-
lation work.
Failure to use the specified parts may result in the unit falling,
water leakage, electric shocks or fire.
• Install the air conditioner on a foundation strong enough to with-
stand the weight of the unit.
If a foundation does not have sufficient strength, the equipment
may fall and cause injury.
• Carry out the required installation work in consideration of strong
winds, typhoons or earthquakes.
If the installation work is not properly carried out, the unit may fall
down and cause accidents.
•
The electrical work must be carried out by the qualified electrician
in accordance with the local and national regulations and this
installation manual. Make sure to provide a dedicated power supply
circuit and never connect additional wiring to the existing circuit.
An insufficient power supply capacity or improper electrical work
may lead to electric shocks or fire.
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor
or telephone earth lead. Imperfect earthing may result in
electric shocks or fire.
A high surge current from lightning or other sources may cause
damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric
shocks or fire.
• Be sure to switch off the unit before touching any electrical parts.
Touching a live part may result in electric shock.
• For wiring, use the specified wires and connect and fasten them
firmly so that no external force from the wires may be applied to
the terminal connections.
If the wires are not firmly connected and fastened, it may cause
heating, fire or the like.
• When wiring the power supply and connecting the remote control-
ler wiring and transmission wiring, position the wires so that the
EL. COMPO. BOX lid can be securely fastened.
Improper positioning of the EL. COMPO. BOX lid may result in
electric shocks, fire or the terminals overheating.
• If refrigerant gas leaks during installation, ventilate the area
immediately.
Toxic gas may be produced if the refrigerant comes into contact
with fire.
• After completing installation, check for refrigerant gas leakage.
Toxic gas may be produced if the refrigerant gas leaks into the
room and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
