Page 8: Testing The Dispensers
Testing the Dispensers Making Timed Deposits of Medium to Thick Fluids (Model 900) You are now ready to test the pre-filled, nontoxic, blue test fluid. This material is representative of thick, non-leveling fluids like sealants, pastes or greases. Check your initial settings: A) Air gauge reads 30 psi. -
Page 9: Programmable Timer
15 psi 10 psi Each 900 series dispenser has a digital timer with programmable time ranges. The DIP switch that controls the timer has been set at the factory for a time range of 0.01 to 1.0 second, with the initiation set to MOMENTARY contact. -

Page 12: Ultra Dispensing System
Advanced Dispensing System If you dispense thick fluids, several problems may For Thick Fluids occur. First, the repetitive air cycles can bore tunnels through non-leveling fluids, causing spit- ting and inconsistent deposits. Second, thick fluids Air Pressure Air Pressure contain trapped air that leads to drooling and oozing. - Page 13 If you use low to medium viscosity fluids, the white For Thinner Fluids SmoothFlow ™ piston has several advantages. First, vacuum adjustment is much less sensitive. Second, the piston prevents fumes from the fluid being exhausted into the work environment. Third, the piston prevents fluid backflow into the dis- penser if the barrel is inadvertently turned upside down.

Page 14: Loading The Barrel Reservoirs
Loading the Barrel Reservoirs Caution: Do not completely fill barrels. The optimum fill is a max- imum 2/3 of the barrel capacity and 1/2 of the barrel capacity when ™ using the LV Barrier If the fluid you are dispensing is pourable, take the barrel, twist on ™... - Page 15 Here are a few suggestions that can help keep your work area clean, save time and reduce the chance of entrapped air in the fluid. 1.
