Before Installation
WARNING
CAUTION
Before Installation
n Don't install or operate the unit in rooms mentioned below.
①
Where mineral oil, like cutting oil is present.
②
Where the air contains high levels of salt such as air near the ocean.
③
Where sulphurous gas is present such as that in areas of hot spring.
④
In vehicles or vessels.
⑤
Where voltage fluctuates a lot such as that in factories.
⑥
Where high concentration of vapor spray are present.
⑦
Where machines generating electromagnetic waves are present.
⑧
Where acidic or alkaline vapor is present.
⑨
The option boxes must be installed with entrances downward.
⑩
If you want to install the product outdoors, it should be installed with outdoor casing.
n Check the mentioned below, when you apply the AHU(Field supply).
①
If the AHU (Field supply) provided in the field is exclusively for heating, you must not
change the operating mode to cooling on the remote controller. If not, it can cause electric
shock, injury or death. If you want to operate in cooling mode, AHU (Field supply) must
comply with the following details.
(Following)
- The insulation level of AHU (Field supply) motor must be ‘F’ or above, and the protection
level must satisfy ‘IP 54’.
- AHU (Field supply) must have the drain pan installed.
②
For refrigerant piping of outdoor unit, refer to the installation manual supplied with the
outdoor unit.
③
For installation of the wired remote controller(PQRCUSA0/1), refer to the manual supplied
with the wired remote controller.
④
For connection of the Dry contact (PQDSBC), refer to the manual supplied with the Dry
contact (PQDSBC).
n AHU Control Kit
①
Thermistor cable and remote controller wire should be located at least 50mm away from
power supply wires and from wires to the controller. Not following this guideline may result
in malfunction due to electrical noise.
②
Use only specified wires, and tightly connect wires to the terminals. Keep wiring in neat
order so that it does not obstruct other equipment. Incomplete connections could result in
overheating, and in worse case electric shock or fire.

Pipe thermistors Installation
Location of the pipe thermistors
A correct installation of the thermistors is required to ensure a good operation :
1. Pipe_In
: Install the thermistor behind the distributor on the coldest pass the heat exchanger
(contact your heat exchanger dealer).
2. Pipe_Out
: Install the thermistor at the outlet of the heat exchanger as close as possible to the
heat exchanger.
Evaluation must be done to check if the evaporator is protected against freeze-up.
Execute test operation and check for freeze-up.

Pipe thermistors Installation
Installation of the pipe thermistor cable
1. Put the thermistor cable in a separate protective tube.
2. Always add a pull-relief to the thermistor cable to avoid atrain on the thermistor cable and
loosening of the thermistor. Strain on the thermistor cable or loosening of the thermistor
may result in bad contact and incorrect temperature measurement.
Fixation of the pipe thermistors (Field work)
1. Fix the thermistor with insulating aluminum tape (Field supply) in order to ensure a good
heat transference.
2. Put the supplied piece of rubber around the thermistor in order to avoid loosening of the
thermistor after some years.
3. Fasten the thermistor with 2 tie wraps.
4. Insulate the thermistor with the supplied insulation sheet.
