Operation manual
HRV – Heat Reclaim Ventilation
Before using the DAIKIN HRV, be sure to read this
operation manual thoroughly. If you have any problems or
there is a malfunction, please refer to this operation
manual. Please keep this manual for your future reference
whenever you do not understand how to use it when
something is wrong with the unit during the operation.
WARNING
Improper handling can lead to such serious consequences
as death or severe injury.
NOTE
These instructions will ensure proper use of the
equipment.
Be sure to follow these important safety cautions.
Keep these warning sheets handy so that you can refer
to them if needed.
Also, if this equipment is transferred to a new user,
make sure to hand over this user’s manual to the new
user.
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 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.
■ 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 noxius gas or corrosive
components of materials such as acid, alkali, organic
solvent and paint, is generated.
■ Place where combustible gas leakage is likely.
Such gas can cause fire.
WARNING
■ Place such as bathroom subjected to moisture.
Electric leak or electric shock and other failure can be
caused.
■ 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
40 ° C. If the unit is used at high temperature, deformed
air filter and heat exchange element or burned motor
result.
■ Place subjected to much carbon black.
Carbon black attaches to air filter and heat exchange
element, marking them unable to use.

Operation method
The remote controller turns on and off HRV unit. (Refer to the section
"Operation with the remote control exclusively for Air conditioning
operation HRV units (BRC301B61)" on page 2)
Combined operation system with VRV systems
and Sky-air series
Operation method
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. (Refer to the section
"Operating the HRV unit using the remote controller of the VRV-
system air conditioner" on page 3)
Operation method
The ON/OFF and timer operation can 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.
(Refer to the section "Operation with the remote control exclusively
for Air conditioning operation HRV units (BRC301B61)" on page 2)
Centralized system
Operation method
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 (DCS302B61)" on page 4)
When the HRV remote controllers is connected, operation can be
started and stopped using the Cetralized 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)
Operation with the remote control exclusively for Air
conditioning operation HRV units (BRC301B61)
For non-independent systems, starting/stopping operation and timer
operation may not be possible.
Use the air conditioner remote control or the Centralized controller in
such cases.

1. Operation lamp
This pilot lamp (red) light up while the unit is in Operation.
2. Operation/Stop button
When pushed once, the unit starts operating.
When pushed twice, the unit stops.
3. Air flow rate changeover button
Air flow rate can be changed over to “
” [Low] mode or
“
” [High] mode,
“ FRESH UP” [LowFRESH UP] mode,
“
FRESH UP” [High FRESH UP] mode.
For “FRESH UP” operation
When this indication does not show: The volume of outdoor air
supplied into the room and that of the room air exhausted
outdoors is equivalent.
For “FRESH UP” operation
• If it is set to “Fresh up air supply”: The volume
of outdoor air supplied into the room is larger
than that of room air exhausted outdoors.
(This operation prevents the odor and moisture
from kitchens and toilets from flowing into the
rooms.)
•
If it is set to “Fresh up air exhust”: The volume
of room air exhausted outdoors is larger than
that of outdoor air supplied into the room.
(This operation prevents the hospital odor and

MAINTENANCE
(FOR AQUALIFIED SERVICE PERSON ONLY)
Maintenance for the air filter
Cleaning frequency
At least once every twoyears (for general office use)
(clean the element more frequently if necessary.)
1Go into ceiling through the inspection hole, remove binding
metal of maintenance cover and take it off. (Refer to figure 3
(A = Models 150~1000F, B = Models 1500~2000F))
2Take out the heat exchange elements from the unit body. (Refer
to figure 4 (A = Models 150~1000F, B = Models 1500~2000F))
3To clean the air filter, lightly pat it with hand or remove dust with
a vacuum cleaner. If excessively dirty, wash it in water. (Refer to
figure 5)
4If the air filter is washed, remove water completely and allow to
dry for 20 to 30 minutes in the shade. When dried completely,
install the air filter back in place. (Refer to figure 6)
5Install the maintenance cover securely in place.
Maintenance for the heat exchange element
Cleaning frequency
At least once every twoyears (for general office use)
(clean the element more frequently if necessary.)
1Use a vacuum cleaner to remove dust and foreign objects on the
surface of the heat exchange element. (Refer to figure 7)
- Use the vacuum cleaner equipped with a brush on the tip of
the suction nozzle.
- Lightly contact the brush on the surface of the heat
exchanging element when cleaning.
(Do not crush the heat exchange element while cleaning.)
2Install the air filter securely in place.
3Put the heat exchange element on the rail and insert it securely
in place.
4Install the maintenance cover securely in place.
When air conditioner and HRV unit
are not connected by duct When air conditioner and HRV unit are connected by duct
CAUTION
Only a qualified service person is allowed to perform
