Operation manual
WARNING + ELECTRIC SHOCK
 Before servicing the unit always
shut off power, otherwise electric
shock may occur.
 Never inspect or service the unit by
yourself.
Ask a qualified service person to
perform this work.
 Always use the air filter.
If the air filter 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.
 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 that they do not play with the
appliance.
 Do not use an HRV or an air
suction/discharge grille in the
following places:
- Places such as machinery plants
and chemical plants where gas,
which contains noxius gas or
corrosive
components
of
materials such as acid, alkali,
organic solvent and paint, is
generated.
- Places where combustible gas
leakage is likely.
Such gas can cause fire.
- Places such as bathrooms
subjected to moisture.
Electric leak or electric shock and
other failure can be caused.
VAM350~2000FB

HRV (Heat Reclaim Ventilation)
4P333250-1A – 2012.11
- Places
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. Unit ambient
temperature conditions should be
between
-15°C
and
50°C
(80% relative humidity or less)
- Places subjected to much carbon
black.
Carbon black attaches to air filter
and heat exchange element,
disabling them.

Operation
Explanation for systems
This product is operated differently depending on the system
configuration.
For the operation of the remote controller for indoor unit and of the
centralized controller, refer to the instruction manual provided with
each unit.
Operation method
The remote controller turns the HRV unit on and off (refer to the
section "Operation with the remote control exclusively for Air
conditioning operation HRV units (BRC301B61)" on page 3).
Combined operation system with VRV systems and Sky-air series
Combination 1

Remote controller
for indoor unit
Operation method
The remote controller for air conditioner turns the air conditioner and
HRV unit on and off.
If only the HRV unit is used without operating the air conditioner, set
the unit in the “
” VENTILATION mode. (Refer to the section
"Operating the HRV unit using the remote controller of the VRVsystem air conditioner" on page 4)
Combination 2
Operation method
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.

Operation method
For “FRESH UP” operation
When the HRV remote controllers is not connected, the Centralized
controller controls the operation of the HRV unit. (Refer to the section
"Independent operation of the HRV unit using the centralized
controller (DCS302C51)" on page 4)
•
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. (Refer to the next sections)

Indication of operation control method:
When the operation of HRVs are linked with the air conditioners,
this indication may be shown.
While the indication is shown, the ON/OFF of HRVs cannot be
operated by the HRV remote controller.
6.
Indication of operation standby:
It indicates the precooling/preheating operation. This unit is at
stop and will start operation after the precooling/preheating
operation is over.
Precooling/preheating operation means the operation of HRVs is
delayed during the startup operation of linked air conditioners,
for example before the office hours.
During this period the cooling or heating load is reduced to bring
the room temperature to the set temperature in a short time.
7.
Indication of centralized control:
When a remote controller for air conditioners or devices for
centralized control are connected to the HRVs, this indication
may show.
When this indication appears on the display, the ON/OFF and
timer operation may not be possible with the HRV remote
controllers.

Maintenance
(for a qualified service person only)
WARNING
When the VRV-system air conditioner is connected with the HRV unit
with a direct duct, the remote controller of the air conditioner cannot
be used to select the VENTILATION mode. To use the HRV unit
without operating the air conditioner, set the air conditioner in the
FAN VENTILATION mode and select the low fan speed.

Be sure to turn off the OPERATION switch and
disconnect the power.

Only a qualified service person is allowed to perform
maintenance.

During operation, never check or clean the HRV. It
may cause electrical shock and it is very dangerous to
touch the rotating part.

Trouble and countermeasure
If your unit does not operate properly, check the following items
Conditions
Causes
The unit does not operate at all.
Check if there is a power failure.
Corrective actions
After power has been restored, start operation again.
Check if the fuse has blown or breaker has worked.
Change the fuse or set the breaker.
Check if the indication of operation control method on
remote controller (BRC301B61) is shown.
This is normal. Operate the unit using the air
conditioner remote control or centralized controller.
(Refer to "Operation" on page 2)
Check if the indication of operation stand by on
remote controller (BRC301B61) is shown.
It indicates the precooling/preheating operation. This
unit is at stop and will start operation after the
precooling/preheating operation is over.
(Refer to "Operation" on page 2)
Amount of discharged air is small and the
discharging sound is high.
Check if the air filter and heat exchange element are
clogged.
Refer to "Maintenance" on page 4.
Amount of discharged air is large and so is the
sound.
Check if the air filter and heat exchange element are
installed.
Refer to "Maintenance" on page 4.
