3-2 How to operate
(1)Turn on power switch.
Pump rotates and metal aspirator exhausts
and starts reducing pressure.
※When starting it up, exhaust sound is loud
because of huge displacement.
※Use cover for bath if it is possible.
It prevents water scattering when releasing
decompression.
※After checking up that the suctioning
nozzle and decompression system are surely
connected, turn on power switch.
If they are not connected, water bubble
may overflow from the bath.
(2)When completing operation, turn off power
switch after releasing decompression.
(1)Turn cap nut and remove suctioning nozzle and
rubber packing on the one side.
Pay attention not to lose rubber packing.
(2)After removing cap nut, place rubber packing
on the part of motor base where screw is fixed,
and insert VG-1000 or VG-1000V and turn cap
nut to fix it.
※ Do not insert VG-1000 or VG-1000V
with a slope.
(3) Connect inlet nipple of VG-1000 or
VG-1000V to vacuum hose and also connect
to decompression system.
(4)To control vacuum degree, unloose the leak valve
slowly with reducing pressure and also reduce vacuum
degree gradually and set up at your desired
vacuum degree(VG-1000V).
※ Instruction for using VG-1000 and VG-1000V
When getting the condition back to normal
pressure, do not pull out vacuum hose with
a sudden jerk or get the condition back to
normal pressure hastily. Releasing
decompression rapidly may break a vacuum gauge.
When getting it back to normal condition,
please pull out the vacuum hose gradually from
inlet nipple or loosen the leak valve slowly.
(only for model VG-1000V).
Procedure after finishing operation
If you don not use the product for a long time,
turn off the power switch and unplug the mains
connector. Also, drain the water of the bath.

※This unit is equipped with backflow
prevention valve that prevents backflow
caused by huge pressure difference, which
was occurred when power switch is turned off
by mistake. However, since backflow
progresses little by little if decompression
is continued for a long time, please release
the decompression. Also, store-bought backflow
prevention valve is available.
In case of trouble, release the decompression
and turn off power switch immediately, and
refer to “Troubleshooting”.
Stop using the product if it does not
work properly.
