Specific Caution Items
Checking Location of Installation
This Heat Exchange Ventilators have been designed especially for use in offices, conference rooms, etc.
Please check to ensure that neither the main unit nor the inlet-outlet grill are installed in any of the following locations.
When Using
Locations exposed to high temperatures or
direct flame.
Avoid installing the Heat Exchange Ventilators
or the inlet-outlet grill in locations which reach
temperatures of 40°C or above.
Usage under high temperature conditions may
cause distortion of the filter or Heat Exchange
Element or motor burn-out.
Locations with high humidity.
Do not install in high humidity locations such as
bathrooms.
Doing so may cause a breakdown of the unit or
an electric shock.
Locations with large amounts of oily
smoke, such as food preparation areas.
The unit will become inoperable if the filter or
Heat Exchange Element become clogged with
oil.
Make sure that Inspection Opening is provided so that filter and
Heat Exchange Element maintenance and periodic spot checks
of the unit can be easily carried out. (Refer to the Model
Installation for its space)
Do not install the unit in locations such as machinery or chemical
plants where it will be exposed to noxious gases containing
acids, alkali, organic solvents, paint fumes, etc., to gases
containing corrosive ingredients, or where dust or oil mist will be
produced.
If there are any problems concerning the location or installation of the unit, please consult either store from which it was purchased
or the agent who installed it.
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.
Operate the switch with certainty.
In particular, suddenly turning the switch
on and off will not only cause improper
operation of the unit, but will also affect the
relay inside the switch, and may damage it.
