MAINTENANCE IN COLD CONDITION

For vacuum strainer

Turn the ring nut while holding and pressing

the strainer cup for the vacuum pump, remove
the strainer and strainer cup.

Inject antifreeze (undiluted 50 ml) to the

strainer guide.

After injection, assemble the

strainer and strainer cup by
tightening the ring nut.

･

When installing the strainer,

exercise  care  so  that  the  O-
ring  does  not  get  caught  in,
and  tighten  the  ring  nut
securely.  If  the  ring  nut  is  not
tightened  completely,  vacuum
leak may occur.

･

Pay attention to the protrusion of

the O-ring while installing the O-
ring. Install it correctly.
Otherwise, a vacuum leak may
occur.

･

When installing the strainer,

tighten the ring nut while
pressing the cup with your palm.

Discharge valve

Fill the inside of the discharge valve with
antifreeze

using a long nozzle containing

antifreeze liquid.
