Multi-Function Water To Water Heat Pump
5.14.The unit water inlet and outlet must install a thermometer, water pressure gage, to facilitate
inspection when operate.
Note:
1) Tubing pipeline should be separate test pressure, must not test with hot water unit or tanks.
2) The water system working pressure: 0.2-0 .7 Mpa.
3) The water system operating temperature: 5-75
.
4) Water can drain from the pressure relief device drainage pipe, and the piope keep open to
atmosphere.
5) The pressure relief device regularly move to remove the calcium carbonate, and prove that
the device is not plugged.
6) Installation of one-way valves, filters and pressure relief device, valve body arrow as same
as flow direction .
7) The pressure relief device discharge pipe should be installed in the frost-free environment in
A continuous down way.
7.Electrical wiring
7
.1.The unit should use dedicated power supply, power supply voltage line corresponding with
rated voltage.
7.2.The unit power cable must use copper cable, the cable diameter must ensure that the unit's
maximum starting current requirements.
7.3.The unit power supply circuit must have a grounding wire, which should connect with a reliable
external ground wire, and the external ground wire is effective.

6.1.The first step
Daub the heat conduction silica gel spreads in the front of sensor, and insert
into the detector.
6.2.The second step
use <
5 pin to push the detector into the end of the detector against the
end of the sensor, and marks on level of the pin and the detector.
6.3.The third step
putout the pin
the position of mark to be at the same level with the inlet of
detector
check whether the sensor is inserted to the pipe terminal.
6.4.The fourth step
the inlet of the detector is sealed with the glass silica gel, and keep the inlet
of the detector upwards and uprightness about an hour
