[7] Water Pipe Installation
1. Schematic Piping Diagram and Piping System Components
<1> Water circuit
Please build the water circuit so that it is a closed
system.
Do not use water directly for showers or other applications.
Do not allow other heat source water to mix with the water
circuit.
Build a water circuit as inlet water temperature fluctuation is
within 5ºC/10 minutes.
Condensation may form in the machine room, depending
on the operation status.
Securely attach the drain pipe.
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.

Strainer
Install a strainer near the unit to keep foreign materials from entering the water-side
head exchanger.
Flow switch
Required to protect the unit.
Drain pipe
Install the drain pipe with a downward inclination of between 1/100 and 1/200. To
prevent drain water from freezing in winter, install the drain pipe as steep an angle as
practically possible and minimize the straight line.
For cold climate installation, take an appropriate measure (e.g., drain heater) to prevent
the drain water from freezing.
Indicates the direction of
the flow.
