Minimum storage period of important parts

Ventilator unit is discontinued, we have the related
important parts in stock for 6 years at least.
The important parts indicate parts essential to
operate the Heat Reclaim Ventilator unit.
Recommendations for maintenance and
inspection
Since dust collects after using the unit for several
years, the performance will be deteriorated to some
extent.
Taking apart and cleaning inside require
technical expertise, so we recommend entering a
maintenance and inspection contract (at a cost)
separate from normal maintenance.
Recommended inspection and maintenance
cycles
[Note: The maintenance cycle is not the same
as the warranty period.]
• Table 1 assumes the following usage conditions.
Normal use without frequent starting and
stopping of the machine.
(Although it varies with the model, we recommend
not start-ing and stopping the machine more than
6 times/hour for normal use.)
• Operation of the product is assumed to be
10 hours/day, 2500 hours/year.

NOTE 1
• This table indicates main parts. See the
maintenance and inspection contract for details.
NOTE 2
• This maintenance cycle indicates the
recommended duration until the need arises for
maintenance work; this ensures the product is
operational for as long as possible.
• Use it for appropriate maintenance design
(budgeting maintenance and inspection fees, etc.).
• Depending on the content of the maintenance
and inspection contract, the inspection and
maintenance cycles may in reality be shorter than
those listed here.
NOTE 3
• Using the unit with a failed motor will lead to
ventilation.
• It is recommended to have the motor inspected
once every 1 to 2 months. (Simple check)
• Motor performance can be examined with a stick
and string or similarly lightweight item attached to
the tip and held at the air supply grille and exhaust
grille for movement.
NOTE 4
• Shortening of "maintenance cycle" and
"replacement cycle" needs to be considered if the
unit is used under severe operation conditions (long
operating hours, very frequent ON/OFF, etc.) and
harsh operating environment (high temperature,
high humidity, etc.).
For details, contact your dealer or the contact center.
