Component Identification
Heater Information
Viscon HF Fluid Heaters (K): Primary heaters that heat
the resin and hardener before mixing. Improves the
chemical reaction and lowers viscosity to improve the
spray pattern. There are two Viscon HF heater variants
(hazardous location heaters and non-hazardous
location heaters). For approval rating, see Models on
page 9 and Approvals on page 11 regarding your
primary fluid heaters.
Viscon HP Fluid Heaters (Y): These are used for heating
water or oil through heated hose to prevent material
from losing heat when spraying remote. They are used
with a diaphragm pump to circulate the heated fluid
throughout the hose. There are two Viscon HP heater
variants (hazardous location heaters and
non-hazardous location heaters). For approval ratings,
see Models on page 9 and Approvals on page 11
regarding your water heated hose fluid heaters.
Hopper Heaters (U): Immersion heaters are used to
heat the outer jacketed area of the double walled
hoppers. The outer jacket is filled with oil or a 50% water
and 50% ethylene glycol mixture to heat the spray
material. The double wall hopper design prevents the
spray material from losing heat.

Pump Information
High Pressure Fluid Pumps (Z): These pumps feed the
A and B fluid.
Solvent Flush Pump (JJ): This pump flushes the mix
manifold, hose, and gun.
Pressure Feed Pump (P): This pump transfers material
from the 25 gallon heated hoppers to the main high
pressure pumps. This is the preferred method of
transferring viscous material compared to gravity feed.
Diaphragm Pump (W): This pump is used to circulate
the heated water through water heated hose.
