Installing the Heater
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
The Viscon HP Heater must be installed
by a qualified electrician in compliance
with all state and local codes and regula-
tions, to reduce the risk of electric shock
or other serious injury during installation
or operation.
When installing in a flammable atmo-
sphere (hazardous location) refer to
Article 500 of the US National Electric Code or
other applicable agency standards to plan the
work.
Refer to the Technical Data and to the supplied
Viscon HP Heater manual 309524 for information
on heater power supply requirements.
Do not plug in or unplug a power cord in any area
containing flammable fluids or fumes, to avoid fire
or explosion resulting in serious injury.
Do not put all flammable materials and debris on
or near the heater. Keep the work area clean.
WARNING
COMPONENT RUPTURE HAZARD
Heat causes fluid to expand. If the
heated fluid is trapped with nowhere to
expand, it can cause component rupture.
Be sure to keep the heated fluid circulating (turn
the 3-way recirculation valve (28) to the circulation
position). Do not install a fluid shutoff device
between the heater and the gun.

Installation
NOTE: Refer to Fig. 2, and to the Dimension drawing
on page 26 and the Mounting Hole Layouts on page
27.
1. Position the heater bracket (49) to the right of the
pump bracket (1), at the same height. The two
slots must face up. The center of the two outer left
holes must be no more than 9 in. (228 mm) from
the right edge of the pump bracket. See page 27.
2. Check that the heater bracket (49) is level. Using
the bracket as a template, mark the four outer
holes on the wall. The four outer holes are used to
mount the bracket to the wall, and the two inner
slots and two inner holes are to mount the heater
(50) to the bracket.
3. Drill four holes in the wall.
4. Bolt the bracket (49) to the wall with 1/2 in. bolts
and washers. Use bolts that are long enough to
keep the bracket from vibrating during operation.
5. Install two screws (S, included with the heater) into
the top two heater mounting posts until they are
about 1/8 in. (3 mm) from fully installed.
6. Using two people, lift the heater (50) onto the
bracket (49) so the two screw heads (S) slide into
the slots. Have one person hold the heater in place
while the other installs the remaining two screws
(supplied with the heater) through the bracket and
into the bottom mounting posts. Tighten all four
screws.
7. Connect the heater supply hose (41) from the
heater inlet elbow (40) to the swivel (13) at the
pump fluid outlet. Tighten securely.
8. Connect the heater outlet hose (45) from the
heater outlet nipple (43) to the inlet fitting (R) of
the fluid filter (15). Tighten securely.
