To prevent environmental pollution,
dispose of brine in the unit or cleaning
solutions according to the local
regulations.
It is punishable by law not to dispose of them
according to the applicable laws.
The water heated by the heat pump is not
suitable for use as drinking water or for
cooking.
It may cause health problems or degrade food.
In areas where temperature drops to
freezing during the periods of non-use,
blow the water out of the pipes or fill the
pipes with anti-freeze solution.
Not doing so may cause the water to freeze,
resulting in burst pipes and damage to the unit
or the furnishings.
■Installation
WARNING
Periodically check the installation base for
damage.
■Transportation and repairs
WARNING
The unit should be moved, disassembled,
or repaired only by qualified personnel. Do
not alter or modify the unit.
Improper repair or unauthorized modifications
may result in refrigerant leakage, water
leakage, injury, electric shock, or fire.
CAUTION
To reduce the risk of shorting, electric shock,
fire, or malfunction, do not touch the circuit
board with tools or with your hands, and do
not allow dust to accumulate on the circuit
board.
In areas where temperature can drop low
enough to cause the water in the pipes to
freeze, operate the unit often enough to
prevent the water from freezing.
Frozen water in the water circuit may cause
the water to freeze, resulting in burst pipes
and damage to the unit or the furnishings.
Use clean tap water.
The use of acidic or alkaline water or water
high in chlorine may corrode the unit or the
pipes, causing water leakage and resultant
damage to the furnishings.
Periodically inspect and clean the water
circuit.
Dirty water circuit may compromise the unit's
performance or corrodes the unit or cause
water leakage and resultant damage to the
furnishings.
As an anti-freeze, use ethylene glycol or
propylene glycol diluted to the specified
concentration.
The use of other types of anti-freeze solution
may cause corrosion and resultant water
leakage. The use of flammable anti-freeze may
cause fire or explosion.
After disassembling the unit or making
repairs, replace all components as they
were.
Failing to replace all components may result in
injury, electric shock, or fire.
