Installation
7. Interconnect reservoir tank (6), Husky 716 pump
Installing the Kit
(16), VISCON HP heater (B), and heated hose
(C-FIG. 1), using tubing (1), tube inserts (15) and fit-
tings (10, 12, 13, 14) as described below.
1. Mount pump (16) on the Xtreme Mix cart (D) using
the bracket (21), lockwashers (4), and nuts (2).
To ensure a leak-proof seal, use PTFE tape on all
pipe thread connections.
2. Mount VISCON HP heater (B-ordered separately)
on the cart using screws and lockwashers (A) sup-
plied with the heater, and the bracket (8), screws
(9), lockwashers (19), and nuts (20) supplied with
the kit.
a. Using tubing cutter (19), cut tubing (1) squarely
to desired lengths.
b. Insert tube inserts (15) in tubing (1) ends to
avoid leakage.
3. Connect nipple (22) and air regulator (7) to Husky
716 pump. Connect 100 psi (0.7MPa, 7 bar) air sup-
ply to the air regulator using air tubing (5), and air fit-
ting (3). Refer to Husky 716 manual if needed.
c. Insert tubing (1) through the back of the nut in
each of the plastic fittings (10, 12, 13, 14) until
the tube stops. Tighten the nut hand tight, then
tighten it 1-1/2 to 2 turns with a wrench.
The air regulator (7) controls pump (16) pressure.
Fitting nuts may need retightening as the system
reaches normal operating temperatures.
WARNING
Connecting Additional Hose Lengths
All wiring must be done by an electrician. See warn-
ings, page 2.
Up to six 50 ft. (15.2 m) sections of heated hose can be
attached for a maximum total length of 300 ft. (91.4 m).
4. Wire VISCON HP heater (B) to your voltage supply.
Follow wiring procedure in the VISCON HP manual.
1. Remove plastic u-turn fittings at the end of the
heated hose assembly. See FIG. 1.
5. Connect elbow (24), fitting (23), o-ring (17), and res-
ervoir tank (6) to Husky 716 pump (16). On other
side of pump, install bushing (11) and tube fitting
(10).
2. Connect the next length of hose, using union fittings
supplied with the hose. Follow fitting assembly pro-
6. Connect tube fittings (12, 13) to the VISCON HP
heater (B).
3. Tubes are color coded. Connect like colors.

Operation
Operation
Each 50 ft. (15.2 m) heated hose section holds
approximately 1.25 gal. (4.7 liters) of fluid.
WARNING
3. Fill reservoir tank (6) about half full. Do not overfill;
fluid needs room to expand as the hose heats.
equipment.
4. Set the flow rate of the circulation fluid to 2 gpm (7.6
lpm) by adjusting the pump’s air regulator (7) until
the pump cycles at 50 cycles/min. Do not use a
higher flow rate as doing so will decrease system
performance and pump life. Never exceed the
hose’s 95 psi (0.6 MPa, 6.6 bar) maximum working
pressure rating.
1. Select fluid to use for heating circulation.
•
•
If ambient temperatures (storage or operating)
are below 40° F (4.4° C), a 50% water and 50%
antifreeze mixture is recommended.
5. Adjust the heater thermostat to the desired hose
temperature. The setting should be about 10° F
(6° C) higher than the desired paint temperature.
Never exceed the hose’s 180° F (82° C) maximum
temperature rating.
If ambient temperatures are above 40° F (4.4°
C), water alone is okay.
Detailed diaphragm pump operating instructions
are in Husky 716 manual.
If the hose is not being used for more than one
hour, shut off VISCON HP heater and Husky 716
pump to lengthen heater life.
2. Pour heating circulation fluid into the reservoir tank
(6), increase air regulator (7) pressure, and cycle
the pump (16). Continue to pour fluid into tank until
all air is purged.
