Test operation
①
Open inlet and outlet
Remove caps (2 places)
from inlet and outlet of
vacuum pump.
②
Check turning direction
Open inlet, turn on electrical
source to start operating
vacuum pump, and Check
that air comes out from outlet.
(Vacuum pump turns
counter-clockwise when
viewed from motor side.)
If air does not come out from
outlet, vacuum pump may turn
in reverse.
In that case, stop vacuum pump,
turn off main electrical source and change 2 out of 3 cords of electric source
connection and change turning direction to correct one.
If you fit pump to vacuum system and control operation of vacuum pump by
remote control,
first check pump itself for turning direction and then fit it to
vacuum system.
