1. Introduction
1.1 Safety Cautions
Cautions and
Warnings
 Be sure to read the following safety cautions before conducting repair work.

The caution items are classified into “ Warning ” and “ Caution ”. The “ Warning ” items
are especially important since they can lead to death or serious injury if they are not followed closely.
The “
Caution ” items can also lead to serious accidents under some conditions if they are not
followed. Therefore, be sure to observe all the safety caution items described below.

About the pictograms
This symbol indicates an item for which caution must be exercised.
The pictogram shows the item to which attention must be paid.
This symbol indicates a prohibited action.
The prohibited item or action is shown inside or near the symbol.
This symbol indicates an action that must be taken, or an instruction.
The instruction is shown inside or near the symbol.

After the repair work is complete, be sure to conduct a test operation to ensure that the equipment
operates normally, and explain the cautions for operating the product to the customer.

1.1.1 Cautions in Operation and Maintenance
WARNING
WARNING
WARNING
OFF
WARNING
Never inspect or service the unit by yourself.
Ask a qualified service person to perform this work.
(The qualified service person)
WARNING: Before obtaining access to terminal
devices ( ), all power supply circuit
must be interrupted.
Electric shock may result. Before servicing the unit,
always shut off power.
Always use the air filter.
If the air fitter is not used, heat exchange elements will
be clogged, possibly causing poor performance and
subsequent failure.
Do not change operations suddenly. It can result
not only in malfunction but also failure of switches or
relays in the body.

WARNING
WARNING Do not use a HRV or an air suction/discharge grille in the following places.
•Place such as machinery plant
and chemical plant where gas,
which contains noxious gas or
corrosive components of mate-
rials such as acid, alkali, organic
solvent and paint, is generated.
Place where combustible gas
leakage is likely.
Such gas can cause fire.
•Place such as bathroom subjected
to moisture.
Electric leak or electric shock and other failure
can be caused.
•Place subjected to much carbon black.
Carbon black attaches to air filter and heat
exchange element, marking them unable to
use.
•Place subjected to high temperature
or direct flame.
Avoid a place where the temperature near
the HRV unit and the air suction/discharge
air grille exceeds 50°C If the unit is used at
high temperature, deformed air filter and
heat exchange element or burned motor
result.

Test conditions are as follows
Notes: 1. Operation sound is measured at 1.5 m below the center the body.
2. Fan speed can be changed over to Low mode or High mode.
3. Operating sound is measured in an anechoic chamber.
Operating sound level generally become greater than this value depending on the operating conditions,
reflected sound, and peripheral noise.
4. The sound level at the air discharge port is about 8 dB higher than the unit’s operating sound.

1.1 Explanation for Systems
This product is operated differently depending on the system configuration.
For the operation of the remote controller for indoor unit and centralized controller, refer to the instruction
manual provided with each unit.

Operation for Each System
System Example Operation Method
Independent
System
The remote controller turns on and off the air
conditioner and HRV unit.
Combined
Operation
System with VRV
Systems and
Skyair Series
The remote controller for VRV turns on and off
the air conditioner and HRV unit.
If only the HRV unit is used without operating
the air conditioner, set the unit in the “
”
VENTILATION mode.
The ON/OFF and timer operation can not be
performed using the HRV remote controllers.
(The indication of centralized control
“ ” appears on the display.)
Other operations can be performed using the
HRV remote controllers. Starting and stopping
operations of the indoor unit and the HRV unit
can be performed using the indoor remote
controllers.
Centralized
System
When the HRV remote controllers is not
connected, the Centralized controller controls
the operation of the HRV unit.
When the HRV remote controllers is connected,
operation can be started and stopped using the
Centralized controller or the indoor and the
HRV remote controllers.
During the indication of centralized control
“
”
appears on the display, the ON/
OFF and timer operation may not be possible
with the HRV remote controllers. Other
operations can be performed using the HRV
remote controllers.
