Setup
Heated System Setup
(Models 222–294 and 222–293 conversion)
Refer to Figure 4.
Use the following procedures to setup Model 222–294
Heated System, or to convert an existing Model
222–293 to a heated system. The Viscon
Heater is
available in three voltages (see page 25). Specify
which voltage you desire.
To setup the pump, first follow steps 1–3 under “Pump
Setup” on page 7.
WARNING
The Viscon
Heater must be installed by a qualified
electrician in compliance with all state and local
codes and regulations, to reduce the risk of electric
shock or other serious bodily injury during installation
or operation.
The power supply must match the heater ’s require-
ments (see “Accessories” on page 25). Refer to the
Viscon
Heater Manual, 307–805, for further
in-
formation.
WARNING
Heat causes fluid to expand, If fluid in the heated por-
tion of your system is trapped with nowhere to ex-
pand, it can cause a system rupture. A system rup-
ture can result in serious bodily injury and property
damage. Be sure your system has an adequate way
to handle heat expansion.
Use flexible hoses between the heater and gun.
OR, install a properly sized accumulator down-
stream from the heater.
OR, install a pressure relief valve, (Graco P/N
237–061) to relieve pressure when it exceeds
the system’s maximum working pressure.
And, never install any shutoff device between
the heater and g;un. If you are using a fluid
regulator before the gun, never use it as a
shutoff device.
Installing Heater Mounting Kit 222–269
WARNING
Before installing the heater, heater mounting kit and
circulating kit, follow the
Pressure Relief Procedure
on page 16. Disconnect all hoses from the pump.
NOTE:
Reference numbers marked with an asterisk
(for example, 29*) are included in kit 222–269.
Apply pipe sealant (3*) to all male threads, except at
swiveling connections.
1. Be sure the wall is strong enough to support the
weight of the heater, hoses, fluid, and stress
caused during operation. Locate the heater wall
bracket (29*) holes 9.25” (235 mm) to the left of
the pump bracket holes, and at the same height.
Use the heater wall bracket as a template to mark
the wall. See “Mounting Dimensions” on page 25.
2. Attach the heater wall bracket to the heater mount-
ing posts with the M8 x 1.25 screws and lockwash-
ers supplied with the heater (53).
3. Use M8 or 5/16” bolts of the appropriate length
and lockwashers (not supplied) to fasten the
heater bracket to the wall.
4.
If you are converting an existing pump,
remove
the fluid filter (8) and long 3/8 npt nipple (9) from
the pump fluid outlet. Discard the long nipple (9).
See Fig. 3.
5. Install the 3/8 npt nipple (35*) in the heater outlet.
Screw the fluid filter (8) inlet onto this nipple.
Unscrew the 1/4 npt nipple (11) from the filter
outlet. Screw the elbow (47*) into the filter outlet,
and screw the 1/4 npt nipple (11) into the elbow.
6. Screw the elbow (30*) into the heater’s inlet.
Attach the heater hose (31*) to the elbow. Attach
the rigid end of the union (32*) to the other end of
the hose (31*).
7. Screw the bushing (46*) into the pump outlet, then
screw the elbow (34*) into the bushing. Screw the
check valve (33*) into the elbow. Be sure the arrow
on the check valve points down. To complete the
heater connection to the pump, screw the swivel
end of the union (32*) onto the check valve (33*).
