7. Installation and transferring works, and checking

Regarding place for installation
Consult with your dealer for details on installation and transferring the
installation.
Caution:
Never install the Fresh Master where there is a risk of leakage of
flammable gas.
If gas leaks and accumulates around the unit, fire can result.
Never install the Fresh Master at the following place:
• where there is much machine oil
• near ocean and beach areas where there is much salt
• where humidity is high
• where there are hot springs nearby
• where there is much sulfureted gas
• where there is a high-frequency processing machinery (a high-fre-
quency welder, etc.)
• where acid solution is frequently used
• where special sprays are frequently used
• Install the Fresh Master horizontally. Otherwise, water leakage can
result.
• Take sufficient measures against noise when installing the Fresh
Master at hospitals or communication-related businesses.
If the Fresh Master is used in any of the above-mentioned environ-
ments, frequent operational failure can be expected. It is advisable
to avoid these types of installation sites.
For further details, consult with your dealer.
Regarding electrical work
Caution:
• The electrical work must be undertaken by a person who is
qualified as an electric engineer according to the [technical
standard respecting electrical installation], [internal wiring
rules], and the installation instruction manual with the abso-
lute use of exclusive circuits. The use of other products with
the power source can result in burnt-out beakers and fuses.
• Never connect the grounding wire to a gas pipe, water pipe,
arrester, or telephone grounding wire. For details, consult with
your dealer.

leakage breaker is mandatory. For details, consult with your
dealer.
Regarding transfer of installation
• When removing and reinstalling the Fresh Master when you en-
large your home, remodel, or move, consult with your dealer in
advance to ascertain the cost of the professional engineering work
required for transferring the installation.
Caution:
When moving or reinstalling the Fresh Master, consult with your
dealer. Defective installation can result in electric shock, fire, etc.
Regarding noise
• In installing work, choose a place that can fully bear the weight of
the Fresh Master and outdoor unit, and where noise and vibration
can be reduced.
• Choose a place where cool or warm air and noise from the outdoor
unit's air outlet do not inconvenience the neighbors.
• If any alien object is placed near the outdoor unit's air outlet, de-
creased performance and increased noise can result. Avoid plac-
ing any obstacles adjacent to the air outlet.
• If the Fresh Master or outdoor unit produces any abnormal sound,
consult with your dealer.
Maintenance and inspection
• If the Fresh Master and outdoor unit is used throughout several
seasons, the insides can get dirty, reducing the performance.
Depending upon the conditions of usage, foul odours can be gen-
erated and drainage can deteriorate due to dust and dirt, etc.
Time to change the humidifying element(GUF-50•100RDH3only)
Because impurities and contamination in tap water accumulate on the
humidifying element, the humidifying power of the humidifying element
decreases gradually.
• If the humidifying power decreases in the course of use, please con-
sider changing the humidifying element (chargeable to the customer).
• Although the time to change the humidifying element varies de-
pending on the conditions such as the operating time and water
quality, it should generally be changed at every five years.
