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-
frequency 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
environments, 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.
- In some types of installation sites, the installation of an earth
leakage isolator is mandatory. For details, consult with your
dealer.

Regarding transfer of installation
- When removing and reinstalling the Fresh Master when you
enlarge 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 out-
door unit's air outlet do not inconvenience the neighbors.
- If any alien object is placed near the outdoor unit's air outlet,
decreased performance and increased noise can result. Avoid
placing 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
generated and drainage can deteriorate due to dust and dirt, etc.
Time to change the humidifying element (GUF-50, 100RDH4
only)
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
consider changing the humidifying element (chargeable to the
customer).
- Although the time to change the humidifying element varies
depending on the conditions such as the operating time and water
quality, it should generally be changed at every five years.
