8.3 Annual Maintenance
Check carbon brushes at least once a year or every 300 hours, whichever comes first. To check your carbon brushes
consult with an authorized Apollo repair facility.
9 Running Multiple Spray Guns With A Turbine
All current Apollo Turbine Models have one air hose outlet on the side of the unit and are designed to run one spray gun.
These models are equipped with an internal air relief valve to accommodate a non-bleed style spray gun (Apollo Model
7500 or 7700).
It is possible to run a 4 or 5-stage turbine system with two spray guns at the same time by installing an optional “Y”
Connector, to the turbine outlet port. It is important to note that if the “Y” Connector is installed and only one spray gun is
operated, the 2nd outlet must be capped or closed so that performance to the single spray gun will not be affected. To install
a “Y” connector follow these instructions:
1. Unscrew the female quick connect from the air outlet located on the side of your turbine.
2. Screw on the “Y” connector. Make sure the “Y” is sideways so you can easily attach your hoses.
3. Screw the female quick connect you removed from your turbine onto the “Y” connector. If you plan on using two spray
guns right away, then make sure you have a 2nd quick connect installed on the other side of the “Y” connector.
4. You are now ready to connect your air hoses and spray guns.
Remember, we do not recommend using the “Y” connector with turbines smaller than 4 or 5-stages. This is due to the power
that each model has. The more stages you have the more power you have. When you are running two spray guns on a single
turbine you are splitting the air power that turbine has. While you will not divide it equally, you will reduce it considerably, so
make sure you do some test areas before you start on your project.
