PRE-START CHECKS
and apply compatible lubricant to the tip and the treaded area
to permit easy removal later.
 Attach proper mixer to applicator tip and tighten mixer nut.

Purge at least 3 mixer volumes of material and discard
static mixer.
The system is now ready for dispensing meter/mixed
materials!
 Keep this instruction manual
 Never permit either material tank to get below
approximately 1/3
full.
 A common problem is cross-over (one material crossing
over into the other material’s manifold and/or hose).
Damage and cost from cross over can be avoided by
carefully following instructions.
 If the gauges display pressures that “peg” the needle,
immediately remove power from machine.
 Air can be trapped in hoses during filling of an empty
system. To avoid trapping air, arrange the hoses to obtain
a continuous gradual upward slope of the hoses from the
pump outlet to the applicator while the system is pumping
at low speed. Point the dispense assembly upward to let
the material push the air out.
 Two zerks are provided on each side of the dispense
manifold, where the static mixer is attached to the
applicator. These are provided so that the operator can
remove the mixer and fill the ports of the manifold with a
compatible lubricant. This helps prevent problems with
material hardening in the manifold, and should be done
when the unit is left unused for any period of time.
 The gerotor pumps are lubricated in two places. Both
should be lubed daily. When the zerk on the top of the
pump is filled, the bleed valve at the bottom of the pump
must be opened. Lubrication is complete when fresh
lubricant is pushed out from the bleed valve.
 Low material temperature raises the viscosity inside the
system, greatly increasing the work required to pump. If
system is to be used in a cold temperature situation,
material & system should be kept as close to or above
room temperature as possible. Any heating of material
must be regulated no higher than maximum temperature
recommended by material manufacturer.

 Check for shipping damage. File claims with the shipper
for any apparent damage.

Remove any plugs and caps from both hoses and attach
hoses and tubing to main system as indicated (if hoses are
shipped detached).

Check for loose bolts, fittings, etc. which may have
loosened during shipping.

Connect motor controller to power supply (120VAC). Use a
ground fault interrupter (not supplied). Using a GFI Plug
will help protect the motor controller and greatly improve
service life.
 If using an extension cord, it must be no longer than 100
feet, 14 gauge. Longer and/or smaller gauge supply may
starve the controller, causing erratic pump performance
and may cause the controller fuse to blow.
 Do a preliminary check of system before filling material
containers. Actuate handle trigger & release signal to stop.
 Filling containers with material: Make sure respective
materials are poured into designated containers. Fill at
least ½ full & place lid on each container immediately after
filling. Make sure inlet valves are open between pumps &
tanks. Label both containers to assure correct filling.
When filling, place lid on tank not being filled.
 Filling hoses and applicator: Actuate system and slowly run
until allowing materials to flow through both hoses to the
applicator. IF MIXER NOZZLE HAS BEEN ATTACHED,
REMOVE TO AVOID MATERIAL CROSS-OVER.
 HOSE FILLING PRECAUTION
: Any high point in hose can
hold air and allow an air gap. Slope hose on a gradual
upward slope away from system to applicator while filling.
The dispense valve should also slope upward in a similar
manner until materials flow smoothly out of both ports of
the dispense manifold. In almost all cases, “A” and “B”
materials behave differently and fill at different rates. Let
earlier appearing material flow into waste container until
other material is also flowing freely.
 Establish proper flow of both materials at dispense
manifold WITHOUT THE MIXER ATTACHED. Hold the
top into a waste container and actuate the system.
Observe flow of both materials from the round ports and
continue to run the system until a positive, air free flow is
achieved. Wipe clean

,
PRECAUTIONS & WARNINGS
Do not install a disposable mixer nozzle to the
dispense manifold until positive air-free flow is
achieved from both outlets of the applicator block tip.
The maximum cord length that can be used is 100 feet
using 14-gauge wire.
