5. Manually cycle the material plunger back and forth
to check for proper operation. Check for hydraulic
leaks and retighten fittings as required. Make sure
the proximity switch is securely tightened and mak-
ing contact, and then return the material plunger to
the closed/recirculation position.
6. Install the chemical hoses to the fittings on the Mix-
Head as follows:
a. Install the isocyanate “close” hose to the Iso
Close Fitting (K).
b. Install the isocyanate “open” hose to the Iso
Open Fitting (L).
c. Install the resin “close” hose to the Resin Close
Fitting (C).
d. Install the resin “open” hose to the Resin Open
Fitting (D).
7. Recirculate both chemical lines until the pressures
stabilize.
8. Pressurize the MixHead and check for chemical
leaks.
Bleeding Air from Hydraulic
Fluid Lines
1. Start the hydraulic fluid motor to build pressure in
the hydraulic lines.
2. Turn off the hydraulic fluid motor.
3. Open the manual unloading valve all the way.
4. Use a bucket to catch the hydraulic fluid, and lay
down a drop cloth to catch spilled hydraulic fluid.
5. At the “close” port of the material plunger (N),
loosen the hydraulic hose very slowly, allow all pres-
surized air to escape, then tighten the hose.
6. Move the cleanout plunger to the “extend” position.
At the “close” port of the cleanout plunger (Q),
loosen the hydraulic hose very slowly, allow all pres-
surized air to escape, then tighten the hose.
7. Move the cleanout plunger to the “retract” position.
At the “open” port of the cleanout plunger (B),
loosen the hydraulic hose very slowly, allow all pres-
surized air to escape, and then tighten the hose.
Install Chemical Hose
8. With the cleanout plunger in the “retract” position,
open the material plunger by manually energizing
the hydraulic directional valve.
9. Have an assistant bleed out any air at the “open”
port of the material plunger (P).
10. Hold the material plunger in the open/pour position
until the “open” port has been completely bled of air
and the hydraulic hose has been securely tightened,
then return the material plunger to the closed posi-
tion.
NOTICE
Before connecting the chemical hoses, make sure the
hydraulic hoses are properly connected and the clea-
nout plunger and material plunger have been tested
for proper operation. Failure to do so may result in
chemical cross-contamination of the MixHead and
proportioning system.
The hydraulic fluid motor must be off and the manual
unloading valve must be completely open before pro-
ceeding to the next step to avoid high pressure
spraying of hydraulic fluid.
An assistant is required for the following steps.
