Check whether products are complete or not!
■Ascertain the same product as you’ve ordered by a name plate and perhaps, if any, damage on delivery.
■Ascertain all components of pumps are complete. (refer to the structure of products)
Warning
A booster system is connected to a pressure tank which has proper capacity and is connected to
the discharge manifold. Especially, the step control type must use a pressure tank, otherwise, it
could cause failures by severe pressure fluctuation and frequent repetition of the start and stop.
8.1)Install location
•
A booster system is for the indoor usage, nevertheless, if installed outdoor, keep the system from rich, wind and extreme temperature.
•The suction of a pump should be pressurized. (recommended suction pressure : 0.2 ㎏f/㎠)
Caution
Water level of a reservoir always keep higher than the top of a pump’s suction part to avoid dry running.
Keep over min. pressure at the suction of a pump.
Especially, must vent air after cleaning a reservoir entirely! And fluctuation of the suction
pressure should be below 1.0 ㎏f/㎠!
•
Install where to be without direct sun light, dirty & humidity and corrosive and inflammable gas whereas, keep pump from
where to have good ventilation.(Admitted surrounding temperature is 0 ~ 40℃.)
•
Install the pump in an easily accessible position to faciliate later inspections or maintenance. Make booster system
handled by a qualified personnel.
•
Install where is close to water source and the length of a suction pipe should be short.
•
If there is a possibility to be frozen to burst, use special complements to avoide freezing.
Warning
Obviously, make facilities for drain to avoid submergence damage by water leakage on
installation, replacement, repair, and pump’s failure!
8.2)Plumbing
•
Pump must remain free of stress from adjoining pipework.
•
Make a suction pipe short and not bent as much as possible.
•
Use a strainer for prevent pumps from a foreign matter interrupting normal pump operation.
•
Recommend to attach flexible joints or valves at a suction/discharge pipe conveniently to disassemble.
•
Recommend to attach a flow pipe at a discharge pipe for conveniently checking.
•
Equip device to avoid water hammer at discharge pipe.
Warning
Enlarge a suction pipe over one level more than standard in case suction is over 10m or bent over
two times. If not so, the fluctuation of discharge pressure could be severe or the protector of dry
operation doesn’t work at suction side. Also, do as the above in case that electric valves attach
to discharge or water demand severely!
Caution
8.3)Electric wiring
Electric Wiring should be performed by a licensed & qualified electrician. In order to prevent electric shock,
the breaker against electric leakage and the grounding should be installed.
•
Electric wiring of the main parts of this production has already been completed.
•
The main(R.S.T) and earth(E) should be wired in accordance with the wiring diagram inside of the control unit.
•
Don’t connect the earth wire with gas pipes, or it could be the cause of an explosion.
•
Please check the following items
①Is a breaker for the electric leakage proper?
②Is the electric wiring proper? ( about the connecting state and the diameter of lines)
③Notice that three terminals of a motor should be firmly assembled.
•
Please check the rotating direction of a pump! The direction is marked on a motor or a pump. Don’t run the pump reversely.
•
Ovserve pump name plate data.
