7-1. Replacement of Consumables

Consumables of the pressurized tube are trap packing,
air inlet packing, rubber tray for dewdrop, trap connecting
packing (material: CR), air inlet connecting rubber (material:
silicon), vacuum hose (material: natural rubber), drain valve,
leak filter, and vacuum sensor. Since degrees of
deterioration and aging depend on specimens and
operating conditions, conduct inspections regularly.
The followings are the procedures of replacement of these
parts.

(4) Replace trap connecting packing or air inlet connecting

rubber. When replacing these parts, put a small amount of
silicone compound for vacuum sealing on their joint part.
Application of the compound will ease the work
of mounting, and improve the sealing performance too.

(5) After replacing the part, reassemble the parts by following

the above Step (1) to (3) reversely.

1. Replacement of trap packing, air inlet packing,

rubber tray for dewdrop

These parts can be removed and fixed easily utilizing their
inherent elasticity.

2. Replacement of air inlet connecting rubber trap connecting

packing

(1) Remove these parts from the equipment.

(2) Untighten 3 pieces of screws fixing the air inlet.

* Prepare screwdriver by yourself.

(3) Remove the top cover for inspection, and untighten the

wing nuts (4 pieces). Connecting trap rubber and inlet
can be removed all together

3. Replacement of Leak Filter

Since the filter is only inserted into the silicone tube, it can be
removed easily.

4. Replacement of Vacuum Sensor

Replacement of vacuum sensor requires removal and
mounting of the sensor and replacement of cable connected
to the vacuum meter on control panel.
Contact the service center of Tokyo Rikakikai to order this
replacement .
