2. Trial Operation
1. Measure the supply voltage and make sure that it falls in the specified range.
2. Set the temperature of the water to a sufficient temperature for heating or cooling (6°C to
60°C).
Trial operation may be disabled in either mode depending on the room temperature.
After trial operation, set the temperature to a normal level.
(26°C to 28°C in cooling mode, 20°C to 24°C in heating mode)
3. The amount of the unit’s water circulation should be 3 L/min to 15 L/min.
Caution
If a special heat exchanger has been incorporated into the unit, the water circulation should
be within the range specified for that product.
If the water circulation is too low, sediment may collect due to stagnation. If too high, the
heat exchanger may corrode due to the fast flow or abnormal sounds and pipe cracking may
occur due to vibration.
The maximum allowable pressure of the unit is 1.18 MPa.
