[7] Water Pipe Installation
1. Schematic Piping Diagram and Piping System Components
Please build the hot water and heat source fluid circuit
so that it is a closed system.
Do not use hot water directly for showers or other
applications.
Do not allow other heat source liquids to mix with the hot
water and heat source fluid circuit.
Union joints/flange joints Required to allow for a replacement of equipment.
Thermometer Required to check the performance and monitor the operation of the units.
Water pressure gauge Recommended for checking the operation status.

Flexible joint Recommended to prevent the noise and vibration from the pump from being transmitted.
Pump
Use a pump that is large enough to compensate for the total water pressure loss and
supply sufficient water to the unit.
Air vent valve
Install air venting valves to the places where air can accumulate.
Automatic air vent valves (such as
') are effective.
Expansion tank Install an expansion tank to accommodate expanded water and to supply water.
' Closed expansion tank Use a closed expansion tank to help manage the concentration of brine.
