HP GRACO OR PRO TI1681A 사용자 설명서

Check and follow all National, State, and Local codes 
regarding air exhaust velocity requirements. 

High velocity air exhaust will decrease the operating effi-
ciency of the electrostatic system. The minimum allow-
able air exhaust velocity is 60 linear ft/min (18.3 linear 
meters/minute).

1.

Install an air line filter/water separator (M) on the 
main air supply line to ensure a dry, clean air supply 
to the gun. Dirt and moisture can ruin the appear-
ance of your finished workpiece and can cause the 
gun to malfunction.

2.

Install a bleed-type air regulator (N) on the gun air 
line (P).

3.

Connect the red-colored Graco Grounded Air Sup-
ply Hose (P) between the gun air regulator (N) and 
the gun's air inlet. The gun air inlet fitting has a 
left-hand thread. Connect the air supply hose 
ground wire (Q) to a true earth ground.

4.

Connect the main air supply line (A) to the 
bleed-type air valve (B). The bleed valve shuts off all 
air to the system. Install an additional bleed-type air 
valve (B) upstream of the air filter (M) to isolate the 
filter for servicing.

Connect the main ground wire (V) to a true earth 
ground.

Always use a Graco waterborne fluid hose between the 
voltage isolation system fluid outlet and the gun fluid 
inlet. See F

. 3.. The waterborne fluid hose (101) con-

sists of an inner PTFE tube (T) and an abrasion-resis-
tant outer jacket (J). Shielded hose 245252 also has a 
conductive layer (C), The conductive layer is connected 
to ground at the gun fitting bracket (104).

Before connecting the waterborne fluid hose to the gun, 
blow it out with air and flush with water to remove con-
taminants. Flush the gun before using it.

Provide fresh air ventilation to avoid the 
buildup of flammable or toxic vapors. Do not 
operate the gun unless ventilation fans are 
operating.

To reduce the risk of electric shock or other 
serious injury, you must use the red-colored 
Graco Electrically Conductive Air Hose for 
the gun air supply hose, and you must con-

nect the hose ground wire to a true earth ground. Do 
not use the black or grey-colored Graco air hoses.

The bleed-type air valve (B) is required in 
your system to relieve air trapped between 
the valve and the fluid supply unit after the 

air regulator (D) is shut off. Trapped air can cause the 
fluid supply unit to cycle unexpectedly, which can 
result in serious injury, including splashing fluid in the 
eyes or on the skin.

To reduce the risk of electric shock, install 
only one continuous Graco waterborne 
hose between the isolated fluid supply and 
the gun. Do not splice hoses together.
