MAINTENANCE

Refilling Pressure Tank

WARNING!

- The pressure in the tank must not exceed the rated maximum.

- Regularly check pre-charged gas pressure in the pressure tank. When checking the pressure, stop the pump and drain the tank. Otherwise the pre-charged gas pressure

cannot be accurately measured.

- Check the pre-charged gas pressure every six months when using proper tank. When refilling the tank,

follow the instructions below: Completely drai n the tank and open the ca p. R efill the tan k wi th an injector or a compressor.

The injected pressure should be 90% of operating pressure or lower by 0.5 kgf/cm

than the pressure. If it is difficult to drain the tank, stop the pump and start refilling the pressure when pre-charged gas pressure is far less than needed.

- If the refilled pressure is much lower than operating pressure, the pressure tank may work abnormally. If the refilled pressure is much higher than operating pressure, the pump may shutdown and restart frequently.

Checking Inverter

The wiring and setting of the inverter is already finished before delivery.

WARNING!

Never change any setting except data related to the operation. The inverter is a semiconductor device that can be damaged by ambient temperature, humidity, and vibration. To prevent malfunctions, pay attention to following:

①

If there is any problem in wiring connections

③

If there is overheating, discoloration, or abnormal smell

②

If there is abnormal vibrations or noise

- To prerent destruction of IC components, do not preform a voltage test or insulation resistance(mega test).

The electronic circuit is embedded in the inverter, so any contact with the inverter may cause static electricity that can damage parts of the inverter. Never touch the electronic circuit when repairing and checking the inverter. Otherwise use a ground connection and earth Chassis when touching it.

- If the bolts and nuts are loosened or rusted, disconnect the power supply, and tighten or replace them.
