D. Mount the collector box to the bracket by sliding
the right and left bracket tabs into the slots on
the collector box.
E. Be sure the 90° rubber ice bin drain elbows are
routed into the collector box.
F. Reinstall the extended splash panel.
5. Fill bin with ice.
6. Set flexible manifold Carb/Non-Carb drinks for correct drink
settings (See Recommended Plumbing Section 2-8).
7. Turn water supply on to the dispenser.
8. Purge air from the carbonator tank. Lift the pressure
relief valve tab on the carbonator tank until water comes
out of the relief valve.
9. Connect the pump deck control lead to the pump motor.
10. Connect power supply cords. (There are (2) two cords
that need to be connected to a 115V power supply.)
11. Brix beverage valves (See Brix Check Section 3-10)
and fill bin with ice.
QUICKDRAW INSTALLATIONS
NOTE: The quickdraw unit requires a supply of CO
2
. The
pressure requirement for the CO
2
supply is 75 psig. The
adjustable Ice Dispense CO
2
regulator in the electric box
must be set at 40 to 45 psi. The Ice Dispense CO
2
Regulator
must never be set above 50 psi.
Turn CO
2
supply on to the dispenser. Each cold carb pump
deck is furnished with a fixed regulator set at 75 psi. Ambient
units need to be set between 90 and 100 psi.
SETTING PRESSURES
Pre-mix Pressures
Normal pre-mix pressure regulators must be set at 60 PSI.
Diet pre-mix pressure regulators must be set at 40 PSI. If you
are experiencing high foaming, decreasing the pressures may
correct the problem. Spitting and popping usually requires
slightly increasing the pressures. Pre-mix beverage valve
pressures vary by type and manufacturer. Please consult the
manufacturer of the valves you are using for specific
instructions regarding operation of the valve.
Cold Carb and Ambient System Pressures
1. Incoming tap water - must be at a minimum dynamic
pressure of 40 psi and maximum static pressure of 55 psi
(measured at inlet to pump).
2. BIB pressure gauge must be set for 60 psi or according to
your line run.
3. Carbonator Pressure gauge (Use Preset Regulator):
-
Cold Carbonation set for 75 psi.
-
Ambient systems must be set at 90 psi to 105 psi.
Important
When installing cold carbonated (Intelli carb) equipment,
never put a tee for the plain water connection in the line
from the pump deck to the cold plate. Putting a tee in the
line will create service problems and bad drink quality.

Warning
Personal Injury - Hazardous Moving Parts
Do not adjust regulator valve above 50 psig.
Recommended operating parameters are 40-50 psig.
Important
The ice portion sizes must be adjusted to customer
requirements at the time of installation. (See the quickdraw
Ice Portion Adjustments section for more information.)
Important
If incoming water pressure is under 40 psi, a water booster
is recommended. If incoming water pressure is over 55 psi,
a water regulating valve is required.
