6.3.3 How to release the pump thermal trip
1.
Shut of the breaker of the customer’s power supply facility.
2.
Remove four screws to remove the front panel and side panel(lower).
3.
Check if the pump thermal switch is tripped.
The pump thermal switch is under the rubber cover.
When you feel the pump thermal switch directly under the cover, the switch is tripped.
If you press the switch from the cover and you do not feel the switch head directly under the
cover, the tripping is released.
(You can not see if the pump thermal switch is tripped from the appearance.)

Be sure to lock out and tag out the breaker of the facility power supply
(customer power supply facility) before wiring.
