It must be replaced by the manufactuer, its sevice agent or similarly qualified persons in order to avoid a hazard.
WARNING CAUTION
■When the system is checked and
the power cable undergoes
maintenance, stop the operation,
and switch the exclusive circuit
breaker "OFF".
The internal fan is revolving at high
speeds and can cause serious
injury. And when using a

properly.
■Don't use benzene or metal brush
when cleaning the filter and heat
exchange element.
Otherwise, the unit will get unfit for
use.
■The filter should be
cleaned regularly.
Dust or dirt building-
up on it can lead to
a lack of oxygen in
the room.
■Use gloves when
cleaning the filter or
heat exchange
element.

Model Installation
In order to prevent the reduced effectiveness of your Energy Recovery Ventilator, be sure to clean dirt and dust from the filter and
Heat Exchange Element at regular intervals.
Caution
Be sure to turn the power off, and to switch
the exclusive breaker off before carrying
out maintenance activities.
Do not immerse the filter or other resin
components in water 60°C or above.
Never use water on the motor, the switch,
or the Heat Exchange Element.
Do not use the following items for cleaning. Avoid using heat to dry the filter, as it may
cause changes in shape or quality.
Always be sure to use a filter.
Failure to do so may cause dust and dirt to
build up on the heat exchange element,
lowering its efficiency and rendering it
inoperable.
