Arctic Pak Hose Replacement Set
16 .1 General Information
In ambient temperatures below 65°F (18°C), use of arctic Pak heated
chemical hoses is often required for consistent, quality results . The
arctic Pak will keep the chemicals at an even, warm temperature to
allow uniform processing .
This product is primarily intended to keep already warmed materials at
temperature during transit to the dispensing InSTa-FlO™ Gun . Chemi-
cal tanks should be stored in a warm location until use, and may require
use of a tank heater band set (please see Section 15) .
The arctic Pak is used in place of unheated chemical transport lines
where described throughout this manual (Sections 3 .3 and elsewhere) .
dO nOT use standard 30 foot FROTH-PaK hoses in an arctic Pak
heated jacket .
dO nOT use arctic Pak hoses in place of nitrogen lines or for
conveying non-polyurethane chemicals of any type .
dO nOT use the arctic Pak with any flammable materials .
Standard unheated chemical lines are 30 feet in length, but are often
connected in series to produce longer lengths as job needs require .
locate unneeded hose (if any) out of the traffic path to prevent a trip
hazard . never attempt to cut the arctic Pak to a shorted length or to
splice in additional hose .
The arctic Pak is fully pressure checked and is flushed with
nitrogen at the factory prior to shipment . To keep the hoses from having
moisture or other undesirable materials introduced into them, please
keep the hose end plugs in place
until beginning installation .
16 .2 Preparing and Installing the Arctic Pak
1 . unpack and examine your arctic Pak for possible
shipping damage . Do not use if damage has occurred .
2 . as per Section 3 .3, connect your Gun/Hose assembly
to the in-line on-off valves .
3 . Remove plugs from the dispenser end of the hose .
The dispenser end is the end without the electrical
cord entering it . Connect the in-line on-off valves to
the dispenser end of the arctic Pak hoses and tighten
securely . Close the on-off valves if not already closed .
4 . The electrical cord servicing the heaters enters at the
tank end of the jacket . Remove plugs from the tank
end of the hose .
5 . Connect the tank end of each hose to the appropriate
chemical tank on-off valve . The hose with the red
colored sleeve and blue body should connect to the
isocyanate tank . The blue sleeved, black bodied hose
should connect to the polyol tank . Close the on-off
valves if not already closed .
6 . Follow the remaining operating manual instructions
for Chemical Hose Installation (Section 3 .3) . also
execute the instructions regarding System Pressuriza-
tion (Section 4 .1), and System Purging and Testing
(Section 4 .3) as they are the same for both heated and
