Graco 1050H Manual De Usuario

Installation

Check your system electrical continuity after 
the initial installation, and then set up a regular 
schedule for checking continuity to be sure 
proper grounding is maintained.

1. Install an air regulator (C) and gauge to 

control the fluid pressure. The fluid stall 
pressure will be the same as the setting of 
the air regulator.

2. Locate a bleed-type master air valve (B) 

close to the pump and use it to relieve 
trapped air. Be sure the valve is easily 
accessible from the pump and located 
downstream from the regulator.

3. Locate another master air valve (E) 

upstream from all air line accessories and 
use it to isolate them during cleaning and 
repair.

4. An air line filter (F) removes harmful dirt 

and moisture from the compressed air
supply.

5. Install a grounded, flexible air hose (A) 

between the accessories and the 1/2 npt(f) 
pump air inlet (D). Use a minimum 3/8 in. 
(10 mm) ID air hose. 

1. Connect an air supply line to the pump (A, 

2. Insert 5/32 OD tubing into the push-to-con-

nect fitting on each pilot valve (113).

3. Connect remaining ends of tubes to exter-

nal air signal, such as Graco’s CycleFlo

™

 

(PN 195264) or CycleFlo II (PN 195265) 
controllers.

Pulse Count models are intended for use with 
customer-supplied fluid management or inven-
tory tracking systems. Attach an M12, 5-pin 
female cable to connect the reed switch to your 
data monitoring system. See Manual 406824.

Trapped air can cause the pump to cycle 
unexpectedly, which could result in serious 
injury from splashing.

Pilot supply pressure should not exceed 
25-50% of main air supply pressure. If pilot 
supply pressure is too high, the pump could 
leak air or exhaust excessive air at stall.
