P.8
·
Do not step on the pump or place object on it.
·
The exhaust piping made by polyvinyl chloride causes the noise through the pipe.
·
Do not apply the power supply from the pump's power pack to any other equipment
as this will result in malfunctioning of the control units and in pump failure.
·
Use the correct wiring materials and size to match the operating conditions in
accordance with the power consumption rating and ambient air temperature of the
pump.
·
Vents at both ends, both side, and top of the pump. Place the pump enough space
from the stationary section. If the cooling air supply is insufficient, the pump
temperature will rise and problems such as rotor contact will occur.
·
Install pump in a location at an ambient not exceeding 40 deg C. Particular caution is
required when the pump is operated in an enclosed room.
·
Never operate the pump without pump cover for safety.
NOTE
·
Pump must be placed in an upright position. Do not stack as packing. When the
pump is overturned, this will result in accident.
·
To fix the pump, the height-adjustment feet of four each are attaches. If the pump is
not stable, vibration and noise of the pump may be increased.
·
Do not wire vacant pins.
·
Apply a 24V DC power for input signals on the pump side. Do not apply this voltage
on the equipment side.
·
Be sure to wire all signals with the correct polarity (+/-).
·
When output signals are used to energize an inductive load such as a relay, be sure
to insert a diode (100V. 1A class) in order to absorb the back electromotive force due
to surge currents.
·
The pump cannot start while the measuring instruments are booting after the ＣＰ is
placed in the ON position.
·
The pump will not start when an ALARM has been generated. After you have taken
the remedial action, reset the pump.
