First: Unpack and use the checklist enclosed with
the Dispenser Kit to identify all items. If there is
any discrepancy, please call us immediately.

Second: Power and compressed plant air should
be available where the dispenser is to be set up.
Air pressure should be between 80 and 100 psi
(5.5 and 6.9 bar). If you are not using an EFD five­micron filter regulator #2000F755, be certain

your plant air is properly filtered and dry and
a regulated, constant air pressure is supplied
to the dispenser.

Note: Model 900-CA is supplied with an EFD five­micron filter regulator with coalescing filter
(#2000F756).

Bottled nitrogen can be used.
Warning: If high pressure bottled air or nitrogen is

used, a high pressure regulator must be installed
on the bottle and set at 100 psi maximum. The
2000F755 filter regulator is not recommended.

Check the voltage label to be certain it is set to the
available power.

Third: Now is a good time to ACTIVATE your
extended Two Year Limited Warranty. Please fill
in and return the postage paid Warranty card. Or
if you prefer, call the appropriate toll-free number
listed below, provide the serial number of your
dispenser and respond to a few short questions.
You are then assured of complete protection for
two years.

Hookup

❶ Connect the air input hose to a plant air source. Set plant air

supply within 80 to 100 psi (5.5 to 6.9 bar). Where required, use
an EFD five-micron filter regulator #2000F755 (see Warranty).

❷ Attach the air input hose coupling to the dispenser. Pull back

metal ring to attach to dispenser.

❸ Plug in the polarized foot pedal connector.
❹ Check the voltage label on the input voltage selector cartridge.

To change the voltage, remove the voltage selector from the
cartridge, rotate it and position the correct voltage to show
through the cartridge window. Replace the cartridge into the
power cord receptacle and insure that both sides snap securely
into position. Install the power cord.

Note: For 900-15 and 900-CA dispensers, use the test barrel filled
with clear fluid and the red 25 gage tip. Refer to “Making Timed
Deposits of Watery-thin Fluids” on page 10.

❺ Attach the 10cc barrel pre-filled with blue, nontoxic test fluid

(included with the dispenser) to the 10cc adapter head.

❻ Take the 10cc barrel adapter assembly (#5150 on the adapter

head) and insert the black, male quick-connect into the air
output fitting on the front panel and turn clockwise to lock. Place
the barrel in the barrel stand.

❼ During the initial testing, you will not use the vacuum control.

Keep this control shut off (turned completely clockwise—do not
force).
