Typical Application Examples; Application 1 - Daikin EKHBHE008BA3V3 Installation Manual

Caution
Earth the unit.
Earthing resistance should be according to local and national
regulations.
Do not connect the earth wire to gas or water pipes,
lightning conductor or telephone earth wire.
Incomplete earthing may cause electric shocks.
Gas pipe.
Ignition or explosion may occur if the gas leaks.
Water pipe.
Hard vinyl tubes are not effective earths.
Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a lightning
bolt.
Install the power wire at least 1 meter away from televisions or
radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 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 the
refrigerant 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.

1 Outdoor unit
2 Indoor unit
3 Heat exchanger
4 Pump
5 Shut-off valve
Pump operation and space heating
When the room thermostat (T) is connected to the indoor unit, the
pump (4) will operate when there is a heating request from the room
thermostat, and the outdoor unit will start operating to achieve the
target leaving water temperature as set on the user interface.
When the room temperature is above the thermostat set point, the
outdoor unit and pump will stop operating.
Make sure to connect the thermostat wires to the correct
terminals (see "Connection of the thermostat cable" on
page 19) and to configure the DIP switch toggle switches
correctly (see "Room thermostat installation configuration"
on page 21).
