Operation  
Operation  
Pressure Relief Procedure  
WARNING  
Do not exceed the Maximum Incoming Air Pressure  
of the equipment. Over pressurizing can cause com-  
ponent rupture and serious injury.  
WARNING  
To avoid injury, relieve air and fluid pressure before  
checking, cleaning, or repairing the equipment.  
Auto Drain  
The following is a basic pressure relief procedure. Be  
sure to follow the specific pressure relief procedure in  
your spray gun and/or fluid supply equipment manuals.  
When the bowl is pressurized, the piston travels down  
against the spring and closes the drain opening. When  
the bowl is depressurized (i.e., overnight when system is  
shut down), the spring lifts the piston from the seal,  
allowing the bowl to drain.  
1. Close the main air shut-off valve.  
2. Trigger the gun or dispense valve and open any  
drain valves to relieve pressure.  
You can push the piston stem on the bottom of the  
bowl to manually drain it.  
Coalescer Pressure Drop  
Indicator  
The differential pressure drop indicator provides early  
detection of a clogged coalescing filter element. As the  
filter element becomes clogged, the red indicator starts  
to rise while air is flowing through the unit. When the  
pressure drop across the element reaches 10-12 psi  
(69-83 kPa, 0.7-0.8 bar), the red indicator will be in full  
view, and the element should be replaced. Failure to  
replace the element when the pressure drop exceeds 10  
psi (69 kPa, 0.7 bar) will affect your air quality and tool  
efficiency.

Maintenance  
Maintenance  
Coalescers with Auto Drain  
Relieve the pressure before cleaning, checking  
or repairing equipment. Follow Pressure  
It is recommended that Air Filter 234402 be  
installed upstream of the coalescing filter to  
remove 5 micron and larger size particles and sep-  
arate large droplets of moisture from the air line.  
Check system at least once per shift to ensure  
proper drainage.  
To maintain maximum filtering efficiency and  
avoid excessive pressure drop, filters must be  
kept clean.  
CAUTION  
Never let the liquid level in the bowl reach the base of  
the coalescing element.  
Air Filters with Auto Drain  
Cleaning  
You do not need to remove the complete coalescer from  
the line to clean it.  
Cleaning  
You do not need to remove the complete filter from the  
line to clean it.  
1. Follow the Pressure Relief Procedure, page 4. Be  
sure to shut off the air supply and depressurize the  
filter.  
2. Clean all parts with cleaning solvent and blow out  
coalescer body.  
2. Clean all parts with cleaning solvent and blow out fil-  
ter body.  
3. Replace coalescer element.  
3. Wash filter element in cleaning solvent. Blow the fil-  
ter out from the inside.
