3.1 Pump installation
1
）
Refer to Fig. 4 for mounting dimensions of the pump. Make sure the environment to install the pump satisfies the
following conditions:
- A flat surface indoor (area where exhaust from the pump does not affect peripheral equipment)
- Enough space to perform maintenance
2
）
Lift the pump using the eye nut on the top. Put the mounting plate on a mount. Align the holes on the mounting
plate with the screw holes on the mount and secure it using four bolts with wave spring washers.
<Installing on a stationary mount>
Secure a mount to the floor using anchor bolts to prevent a fall due to pump vibration.
<Installing on a movable mount>
Keep the pump from moving or falling due to pump vibration by securing a mount with a locking device like a
stopper.
3.2 Installation of nylon tube
Please correctly install the nylon tube to the pump by referring to Fig. 1 of "1.1 Part Names".
Then please make sure to insert the nylon tube into the fitting as deeply as possible. After the installation, please
make sure that the nylon tube is firmly connected by lightly pulling it.
3.3 Installation of silencer
CAUTION
-
Each connection is capped. Remove the caps all.
-
Wrap sealing tape around the silencer thread to prevent leakage.
Attach the silencer to the pump and secure it using a tool. (Fig. 5)
Wrap sealing tape around the silencer thread to prevent leakage.
3.4 Connecting suction piping
(connecting pump to inductor plate)
1
）
Insert the lower part of the pump through the gasket into the inductor
plate.
2
）
Rotate the holes in the gasket and flanged part of the pump to align
with the bolt holes in the inductor plate. Insert bolts with wave spring
