Expansion Tank
The enclosed expansion tank can be used for the various water volume caused by
temperature change. It can protect the water pipe from over high pressure.
Installing the expansion tank at the lower place of the water system is recommended.
The tank needs to be insulated in the cold place to avoid freezing.
Safety Valve
The valve can be installed vertically or horizontally. The safety valve can be either vertical or
horizontal installing on the high pressure section
(water outlet of water pump), but can not be upside
down. The drain pipe needs to be connected. Turning on the red knob can manually drain the water.
5br safety valve is recommended.
Auto Water Supply Valve
Auto water supply valve can be either vertically or horizontally installed at the water
return circuit, but not upside down. The water supply volume should be adjusted
according to actual situation.
Shut off the auto water supply valve and open the check valve for maintenance. Loosen
the screw. Take out the valve core to wash or replace it. Set the water supply pressure
after the maintenance.
Electric Heater
When the chiller is working during the wintertime, the heating capacity may be
affected with the drop the ambient temp. In that case electric heater is necessary.
The electric heater is equipped with protection, which can cut off the power to avoid burning.
Open the water valve and start the water pump to discharge the air in the system first. After
the water system works stably, turn on the electric heater. If the electric heater will not be
used during wintertime, please discharge the water.
Install the electric heater at the water outlet through parallel connection. Refer to the
diagram of piping connection.
