HOSES
The equipment has two chemical supply hoses. The hoses are made of braided stainless steel and are
Teflon-lined. Each hose is made to withstand pressures well above the SLUG PRO gun operating pressure.
This adds to the safety of the gun since operating pressures should not exceed 245 p.s.i. Hoses are either
heated by cal-rod units or by heat tape depending on the length of the hose. 25 ft. hoses are heated by
cal-rod mechanisms. 45 ft. hoses and greater are heated by heat tape. Each hose is color-coded, red on
isocyanate (A-SIDE), and blue on polyol (B-SIDE).
STRATOFLEX ASSEMBLY
Stratoflex assemblies consist of a filter and temperature gauge. Stratoflex assemblies are located at the end
of the hose assemblies. Temperature gauges on the Stratoflex assemblies are color coded like the cylinders
(Red = A-SIDE, Blue = B-SIDE). A Stratoflex (Strat) assembly is the device that connects to the chemical
cylinder. Each Strat assembly indicates temperature of chemical and filters possible contaminants. Optimal
operating temperature for most FSI chemical systems is 80°F(±5°F). Temperature readings should be taken
while, or soon after, chemical is flowing to indicate accurate chemical temperature. Refer to your specific
system for temperature parameters located on page 13.
Two Stratoflex sizes exist (½" and 1¼"). Typically ½" Strats are used with F-1000 or smaller cylinders. Both
½" and 1¼" Strats can be used with F-6000 and F-5000 cylinders. When using 1¼" Strats it is impossible
to connect the SLUG PRO gun to the chemical cylinders incorrectly. This is due to the reverse fitting system
between the gun and cylinders. A reverse fitting system does not exist when ½" Strats are utilized. Therefore,
it is important to use extreme caution when connecting ½" Strats to chemical cylinders because connecting
incorrectly (“crossing-over”) is possible. Follow the color coding, matching the A-SIDE (Red to Red) and the
B-SIDE (Blue to Blue).
IMPORTANT: IF COLOR-CODING IS IGNORED, CROSSOVER WILL OCCUR AND THE ENTIRE SLUG
PRO GUN UNIT, HOSES, AND CYLINDERS WILL BE RUINED! CONTACT FSI
IF UNCERTAIN HOW TO CONNECT GUN TO THE TANKS!
NITROGEN REGULATOR(S)
The regulators are the energy source which operate the entire dispensing unit. SLUG PRO equipment
regulator systems typically consist of two high-pressure regulators. The first high-pressure regulator is
connected to only one chemical cylinder. The second high-pressure regulator is connected to one chemical
cylinder and the ¼" air cylinder line. Some 6 & 15-PPM users are able to use one regulator to pressurize both
chemical cylinders and the air cylinder.
HEAT CONTROL UNITS
FSI utilizes two different types of heating units, an HB-01 (Single Digital Heat) Unit and a HB-02W (Dual
Digital Heat) Unit. The HB-01 is used in conjunction with heat tape for 45 ft. and longer gun units. The
HB-02W is used in conjunction with two heat cables (cal-rods) on 25 ft. gun units. Both heating units are
designed so hook up is simplistic.
