6. Installation considerations
!
Caution
When handling refrigerant gas, do not directly touch the gas. This can cause burns due to freezing.
Do not install the water heat exchanger unit where fl ammable gas could fl ow, accumulate or be produced,
or where volatile or fl ammable substances are handled. Fire could occur from ignition of combustible
substances or fl ammable gas.
Connect the drain pipes in accordance with “Procedures and Technical Points for System Installation,”
and provide suffi cient insulation to prevent the formation of condensation. A defect in the piping could
cause water leaks into the surrounding property.
Thoroughly insulate refrigerant piping with insulation material in accordance with “Procedures and Technical
Points for System Installation.” Uninsulated pipes can result in water leaks or burns.
(Insulation on the thick pipe must be able to withstand 120°C or greater.)
Provide a proper dedicated earth ground. Do not connect grounding lines to gas or water
pipes, lightning rod wires, or telephone grounding lines. Electric shocks may occur if the
earth ground is inadequate.
Affi x an overload circuit breaker with the correct load capacity to each unit.
Installing an incorrect breaker can result in fi re due to overheating or short circuits.
