Graco 3A0415D Manual De Usuario

A pressure manometer is a simple device that 
measures pressure output. To build a pressure 
manometer you need a pressure gage (aa), 
tee fitting (bb) and stop valve (cc). F

IG

. 1 

shows a correctly assembled pressure 
manometer, connected to the lubricator and a 
lubrication point.

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

manometer is open.

8. Attach lubricator and adapter (B) to the 

pressure manometer (aa - cc) and turn the 
switch to “ON” (ff) (F

IG

. 1). 

9. Run the manometer for about 20 seconds. 

Observe the gauge and repeat this proce-
dure until the pressure registered on the 
gauge stays constant.

10. To determine the counter pressure, wait 

approximately 5 minutes until the system 
has relaxed. Do one more discharge by 
turning the unit OFF; then ON again until it 
dispenses for no more than 5 seconds. 

11. Wait approximately 5 more minutes to 

make sure the system does not lose pres-
sure and remains constant.

12. To disconnect lubricator from manometer, 

follow pressure relief procedure provided 
on page 4. 

NOTE: In this application, you will be dis-
connecting adapter (B) from manometer 
instead of lubrication point. 

13. If the counter pressure is 5 bar (72.5 psi) or 

higher, flush the 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.

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 EM-120 grease canister about 3 months to 
fill this 1 meter tube.

. 2 illustrates one way to pre fill using a 

grease gun to dispense the grease.

Do NOT disconnect lubricator from adapter 
(B). Screwing anything into lubricator end a 
second time will damage self-sealing threads.
