Daily Maintenance External Mix System

Maintenance Guide – External Mix System:

Spray Gun Maintenance:

1. Routine maintenance for this unique spray gun is not normally necessary other than lubrication of the various O-Rings that seal the FRONT CAP. This will insure easy installation of the parts without tearing the O-Rings. Lubricate the Spray Tip O-Ring as well.

2. When the spray gun is not being used, remove the Front Cap and Spray Tip and place them into a container of suitable clean solvent. This will insure that the spray tip assembly is clean when you are ready to use it again.

3. In order to insure reliable results from your Phoenix Spray Gun, you must routinely clean the over-spray from its outside surfaces. Simply use a clean paintbrush or clean rag with solvent and wipe the gun down thoroughly.

The same is true for the rest of the system, you should wipe down all surfaces daily. A clean rag and solvent work best. Do not wipe the faces of any gauges with solvents. Use a Windex type material instead.

System Maintenance:

5000 Spray Gun Adjustment

After a period of time, the seats in the spray gun will become worn to a point where they will no longer seal completely and the gun will begin to drip material out the front. When this occurs, the packings in the gun will need to be adjusted. Although this is a simple procedure, it can be done incorrectly.

Begin by removing the Front Cap and Spray Tip from the gun.

Using a 3/16” allen wrench, Tighten the two Fluid Plugs in 1/8 turn increments ONLY until the dripping stops. NOTE: It will help to determine the stopping point by intermittently triggering the gun. Do not overtighten. Overtightening causes the rear seal to become overstressed causing them to shear during operation. This will result in a leak in the Yoke area.

DO NOT OVERTIGHTEN!!!!

NOTE: If you have attempted this adjustment and the leak does not stop, you must replace the front seals and seats as spelled out in the Spray Gun Repair Manual.

System Maintenance:

MATERIAL PUMP FILTER

It is important that this filter is cleaned. It is not acceptable to leave a dirty filter in the system (which reduces material volume from the tip) and increase material pressure to recover the volume of material that has been lost. You will extrude the “junk” that the filter has collected by doing so and you will experience clogged tips, gun head, hoses, etc.

To clean the material filter, follow these steps:

1) Locate your material filter on the system.

2) Disconnect your air supply to the system. You should also turn all regulators down to ‘zero’.

3) Wear proper safety gear: Safety glasses, gloves, clothing, etc.

Understand that the material in the system may be under very high pressure and care must be taken to avoid injury.

Place a clean suitable container or 5 gallon pail under the filter assembly.

Slowly open the material relief ball valve under the filter assembly. DO NOT completely open the ball valve unless you are completely certain that all material pressure has escaped the system.

4) Once you are certain that your material is drained from the system and all of the material pressure has been relieved, carefully unscrew the filter housing to expose the filter. Examine the filter, if it has been stretched or warped, replace it. Otherwise, clean it with solvent and re-install the filter. Consult your schematic for the proper filter part number to order a new filter.

5) Now that your filter is clean or has been replaced, follow the directions listed in “Initial Start-Up Procedures” to prime your system and restore proper fluid balance.

System Maintenance:

MATERIAL ACCUMULATOR

Phoenix Systems’ utilize a material accumulator to decrease the pulsation effect of the stroking of the material pump.

Over time, the accumulator will become clogged with particles and the overall effect of the accumulator will be diminished. Depending on the type of material you are spraying/dispensing you may need to clean your accumulator as frequently as once per week.

It is recommended that you at least clean the accumulator in tandem with the material filter. This will save you time as once the system pressure is relieved to clean the filter, it only takes a few extra minutes to clean the accumulator.

Follow all of the steps listed under the MATERIAL PUMP FILTER directions.

Your accumulator can be taken apart for easy cleaning. You should note to inspect the O-Rings on the ends of the accumulator and replace them if necessary.

You may soak the accumulator in solvent to clean it or push a rag through the center of the cylinder.

System Maintenance:

Catalyst Slave Pump & System

The Catalyst Slave System uses a shaft bearing for the slave arms. Although it is lubricated at the factory and should require no normal maintenance, it is recommended to add grease to the bearing periodically.

Phoenix uses special self-adjusting aerospace seals instead of “packings” on all of our pump shafts. “Packings” cause excessive friction and do not self adjust for wear. Because of this, if the upper seal begins to leak, it must be replaced, Attempting to tighten it, will not help.

System Maintenance:

Air Motor

The Phoenix Air Motor does not need to be oiled. The Air Motor Piston Seal is Teflon and is self lubricating. The only real maintenance is preventative. Ensure that clean, dry air is available for the air components of the system.

System Maintenance:

Material Pump

The Phoenix Material Pumps utilize a very unique design.

The Lubricant Reservoir is located at the top of the fluid pump. This reservoir should always remain 2/3 to completely full in order to protect the material pump shaft from over-spray, dust, etc. Use Phoenix Throat Seal Lubricant (Part # TSL-8).
