AFETY CONSIDERATIONS
The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.
Meanings of DANGER , WARNING , CAUTION and NOTE symbols.
DANGER
Indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It may also
be used to alert against unsafe practices.
NOTE
Indicates situations that may result in equipment or
property-damage accidents only.
Danger
Before touching electric terminal parts, turn off power switch.
When service panels are removed, live parts can be easily
touched by accident.
Never leave the unit unattended during installation or servicing
when the service panel is removed.
Do not touch water pipes during and immediately after operation
as the pipes may be hot. Your hand may suffer burns. To avoid
injury, give the piping time to return to normal temperature or be
sure to wear proper gloves.
Do not touch any switch with wet fingers. Touching a switch with
wet fingers can cause electrical shock.
Before touching electrical parts, turn off all applicable power
supply.
Warning
Tear apart and throw away plastic packaging bags so that
children will not play with them.
Children playing with plastic bags face danger of death by
suffocation.
Safely dispose of packing materials. Packing materials, such as
nails and other metal or wooden parts, may cause stabs or other
injuries.
The piping between solar panels, solar pump station and solar
kit shall be copper piping and properly insulated. The piping can
reach the same temperature as the maximum allowable solar
panel temperature.
The piping between heating circuit and solar kit connection shall
be copper piping, at least 1.64 ft (0.5 m) long and properly
insulated.
Due to heat conduction, the piping can become very hot.
Installation and operation manual
2
VJU = 2~, 208/230 V 60 Hz
Do not touch the internal parts (pump, etc.) during and
immediately after operation.
Your hands may suffer burns if you touch the internal parts. To
avoid injury, give the internal parts time to return to normal
temperature or, if you must touch them, be sure to wear proper
gloves.
Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
Caution
Ground the unit.
Grounding resistance should be according to local laws and
regulations.
Do not connect the ground wire to gas or water pipes,
lightning conductor or telephone ground wire.
Incomplete grounding may cause electric shocks.
Gas pipe.
Ignition or explosion may occur if the gas leaks.
Water pipe.
Hard vinyl tubes are not effective grounds.
Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
Install the power wire at least 3.28 ft (1 meter) away from
televisions or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.28 ft (1 meter)
may not be sufficient to eliminate the noise.)
Do not rinse the unit. This may cause electric shocks or fire.
Do not install the unit in places such as the following:
Where there is mist of mineral oil, oil spray or vapour.
Plastic parts may deteriorate, and cause them to fall out or
water to leak.
Where corrosive gas, such as sulphurous acid gas, is
produced.
Corrosion of copper pipes or soldered parts may cause water
to leak.
Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system, and
cause malfunction of the equipment.
Where flammable gases may leak, where carbon fibre or
ignitable dust is suspended in the air or where volatile
flammables, such as thinner or gasoline, are handled.
Such gases may cause a fire.
Where the air contains high levels of salt.
Where voltage fluctuates a lot, such as that in factories.
In vehicles or vessels.
Where acidic or alkaline vapour is present.
