To reduce the risk of injury, do not sit, stand, or place objects
on the unit.
Do not connect the makeup water pipe directly to the
potable water pipe. Use a cistern tank between them.
Connecting these pipes directly may cause the water in the
unit to migrate into the potable water and cause health
problems.
To reduce the risk of adverse effects on plants and animals,
do not place them where they are directly exposed to
discharge air from the unit.
Do not install the unit on or over things that are
vulnerable to water damage.
Condensation may drip from the unit.
The model of heat pump unit described in this manual is not
intended for use to preserve food, animals, plants, precision
instruments, or art work.
To reduce the risk of injury, do not touch the heat exchanger
fins or sharp edges of components with bare hands.
Do not place a container filled with water on the unit.
If water spills on the unit, it may result in shorting, current
leakage, electric shock, malfunction, smoke, or fire.
Always wear protective gears when touching electrical
components on the unit.
Several minutes after the power is switched off, residual
voltage may still cause electric shock.
To reduce the risk of injury, do not insert fingers or foreign
objects into air inlet/outlet grills.
To reduce the risk of injury, wear protective gear when
working on the unit.
Do not release refrigerant into the atmosphere. Collect
and reuse the refrigerant, or have it properly disposed of
by an authorized agency.
Refrigerant poses environmental hazards if released into the
air.
Transportation
WARNING
Lift the unit by placing the slings at designated
locations. Support the outdoor unit securely at four
points to keep it from slipping and sliding.
If the unit is not properly supported, it may fall and cause
personal injury.
CAUTION
To reduce the risk of injury, do not carry the product by the PP
bands that are used on some packages.
Installation
WARNING
Do not install the unit where there is a risk of leaking
flammable gas.
If flammable gas accumulates around the unit, it may ignite
and cause a fire or explosion.
HWE10060
To prevent environmental pollution, dispose of brine in
the unit and 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.
In areas where temperature drops to freezing, use an anti-
freeze circuit and leave the main power turned on to prevent
the water in the water circuit from freezing and damaging the
unit or causing water leakage and resultant damage to 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.
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.
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.
To reduce the risk of injury, products weighing 20 kg or more
should be carried by two or more people.
Properly dispose of the packing materials.
Plastic bags pose suffocation hazard to children.
