Preparation for Operation
HEC002-A/HEC006-A 7-3
Operation of the pump with the plenty of air left in the piping for
prolonged period may cause the pump to break. Exhaust the air enough
from the piping before starting operation of the pump.
Take enough care not to spill the feed water over the case when
supplying water to the reservoir. When it is spilt by mistake, wipe it off
immediately and supply the power after it dries. If this procedure is
neglected, it may cause breakdown of the equipment.
Do not perform operation under the condition which lowers the flow rate
significantly, such as closing the valve. Other wise, the temperature
might be beyond control.
If the fluid with low conductivity such as DI water is used as circulating
fluid, it causes static electricity due to friction and damages the
temperature sensor and other electric components of this unit. Take a
measure to minimize static electricity from circulating fluid.
If the power switch is turned on without circulating fluid, the pump is
damaged.
The product is damaged when driving for a long term with the
temperature staggered periodically after reaching the target temperature.
Please set the PID value again by using auto-tuning function (see
section 5.3).
7.5 Check
･
Repair
The following checks shall be performed before operation.
7.5.1 Daily check
1) Indication of display panel : Check temperature condition and confirm whether or not the alarm
occurs.
2) Filter : Confirm there is not attachment of the dust on the filter at suction port. A lot of attachment
may impair performance. We will recommend the removal of dust once every three months.
3) Confirm there is no leakage of circulating fluid or no bending or crush of the piping of circulating
fluid.
4) Confirm there is no abnormal sound or smell or abnormal heating of the case.
