INSTALLATION AND ASSEMBLY
17
It is imperative that the following information is read thoroughly and understood before connecting
the SLUG PRO gun to the chemical cylinders, and any initial assembly, disassembly, or maintenance
of the FSI foam unit.
CYLINDER PREPARATION AND CONNECTION
Ensure that A-SIDE (Isocyanate) and B-SIDE (polyol) chemical cylinders are placed together in the same
environmental temperature. Chemical component temperatures should be at a minimum of 70°F and
a maximum of 90°F. Keep in mind that the temperature restrictions are parameters. Ideal temperature
is between 75–85°F. Chemical cylinders should be brought to proper operating temperatures before
connecting to the SLUG PRO gun.
PROCEDURE FOR CONNECTING CYLINDERS
1. Make sure that all ball valves on the chemical cylinders are in the OFF position.
2. Remove hexagon shaped sealing caps from the top of each cylinder. For A-SIDE cylinder, thoroughly
remove protective grease from Stratoflex coupling and place in A-SIDE cap before connecting.
Apply a thin film of petroleum jelly to the thread area before connecting the corresponding female or
male assembly.
REMEMBER: Always match color-coded Strat assembly with color-coded cylinders before
connecting. A-SIDE = Red, B-SIDE = Blue
3. Make sure that the fittings on the Stratoflex assemblies are cleaned with DK 817 solvent (do not use
acetone).
4. Connect B-SIDE Strat assembly to B-SIDE (Polyol) chemical cylinder. Connect A-SIDE Strat assembly
to A-SIDE (Isocyanate) chemical cylinder. Make sure that the ball valves are held in place and do not
turn during connection.
5. Tighten Stratoflex fittings until fully engaged. Make sure that the ball valves are held in place and do not
turn during connection.
NOTE: When fully engaged, the Strat assembly will not rotate.
NITROGEN CONNECTION
Attach Nitrogen (N2) regulator(s) to N2 supply source(s). Make sure that connection between the N2 supply
source(s) and regulator(s) are tight and not leaking. N2 regulator connections are as follows:
2 Hoses: From regulator 3/8
" N2 supply lines connect to corresponding N2 connectors on chemical
cylinders.
1 Hose: From gun unit ¼ " hose connects to JIC fitting on regulator.
(Hose supplies solenoid and air cylinder)
AIR PURGE CONNECTION
1 Hose*: Attach 3/8
" air line from foam gun unit to DRY IN PLANT AIR for air purge. Maximum 50°F/10C°
Dew Point Air, Minimum 100 p.s.i./6.9 Bars.
*Hose can be connected to Dry or Pure Nitrogen.
