Water pipe installation
It is recommended to use closed circuit cooling tower. If open cooling tower is applied, use intermediate heat exchanger and
make sure that supplied heat source water system is closed circuit.

※
From above illustration, flow switch (mandatory) and 2way solenoid valve (optional) must be at least equivalent
to the specification recommended by our company and they should be installed horizontally.
When water pipe circuit freezes, it will cause damage to the plate type heat exchanger and therefore
preventive measure must be taken according to the situation.
•
Drain remaining water in the water pipe when it will not be used for long period of time
•
Constantly operate the water pump to circulate the water within the water pipe
•
Install self-regulating heat cable on the water pipes

Note 2)
Note 1): Anti-freeze must be used when temperature of water inlet for heating is below 10°C or ground heat source is used. Maintain
appropriate concentration level of anti-freeze according to temperature of water inlet.
Note 2): Strict management of anti-freeze concentration level is required. Consult Samsung before application.
Note 3): When inlet water temperature is outside of limit, consult Samsung before application.
