Installation and Setup

8 3A1898B

3. Install lubricator unit

into adapter (B).

4. Install reducers, extensions, grease line,

etc. (if necessary).

5. Screw a pressure manometer into the lubri-

cation point (dd) (FIG. 3, page 7).

6. Ensure the stop valve (cc) of the pressure

manometer is open.

7. Attach lubricator and adapter (B) to the

pressure manometer as shown in FIG. 3

and turn the switch to “ON” (ff).

8. Run manometer for about 20 seconds.

Observe gauge and repeat this procedure

until pressure registered on gauge stays

constant.

9. To determine counter pressure, wait

approximately 5 minutes until system has

relaxed. Do one

more discharge by turning

unit OFF; then ON again until it dispenses

for no more than 5 seconds.

10.Wait approximately 5 more minutes to

make sure system does not lose pressure

and remains constant.

11.Disconnect adapter (B) from manometer.

12.If counter pressure is 4 bar (58 psi) or

higher, flush lubrication point with a grease

gun.

If the counter pressure does not decrease

you may need a different lubricant or size

lubricator canister. Contact Graco Cus-

tomer service for assistance.

Priming / Prefilling Fittings and

Grease Lines

All accessories and grease lines must be

primed/pre filled. Without this priming/pre fill-

ing, the lubricator would first have to fill the

accessories with lubricant.

Example: A tube that is one meter long

requires about 28 cm

3

of lubricant. It would

take the lubricator with a 12 month setting and

an TC-130 grease canister about 3 months to

fill this 1 meter tube.

FIG. 4 illustrates one way to pre fill using a

grease gun to dispense the grease.

NOTICE

Do NOT disconnect lubricator from adapter

(B). Screwing anything into end of lubricator a

second time will damage self-sealing threads.
