Reef relief chiller

[L0rdDracula]

Hi i got this Reef relief chiller weeks ago from a reefer and i forgotten which is in and out direction for water flow for the chiller to work. Can anyone enlighten me whether if the left or right side is the place for the water to flow into the chiller? thanks(photo is attached at the bottom).

Either one also can but only problem is the thermostat sensor placing. If the thermstat sensor is placed on the inlet, then it will give the correct sensing and the chiller will on/off properly according to the tank temperature.

If you put the water outlet near the sensor, the chiller will cut in/off according to the chiller temperature which will be very frequent.
