Operation

Flushing the Heater Before First Use

The heater was factory tested in lightweight oil. Use
low pressure and a compatible solvent to flush the
system. While the system is pressurized, check it
carefully for leaks at all fluid connections. Pump out
the solvent, relieve the system pressure, and tighten
any leaking connections. Prime the system and check
to be sure that all leaks have stopped.

WARNING

To reduce the risk of serious injury when flushing:

1.

Use the lowest possible pressure to reduce the
risk of fluid injection and splashing solvent in
the eyes or on the skin.

2.

Maintain firm metal-to-metal contact between a
metal part of the gun and a grounded metal pail
to reduce the risk of static sparking which can
cause a fire or explosion.

WARNING

To reduce the risk of serious injury from a fire or
explosion, never operate the heater with its covers
removed.

Priming the System (Refer to page 6)

Pump the fluid until all air has been purged from the
system, to permit proper heating and spraying. In a
completely closed, circulating system, use a director
valve (L) attached to the pump intake to purge the
system. See the Typical Installation on page 6.

Setting the Heater Controls (See Fig. 4)

NOTE: The knob settings for Series E and older
Vis–Con heaters will differ from Series F heaters
(covered in this manual). It’s important that you take
this into consideration when setting the heaters. Refer
to the charts which illustrate the difference.

1.

Stop the pump.

2.

Set the control knob (V) at 4 or 5 (trial setting) and
let the heater warm up for about 10 minutes. See
Fig. 5.

NOTE: Start the pump and circulate the fluid at a low
speed – 10 to 20 oz/min. (0.30 to 0.35 liter/min.) –
during the warmup.

Adjusting for Spraying

1.

Start the pump and check the fluid flow through
the gun.

2.

Readjust the control knob setting, if necessary, to
obtain the proper temperature for spraying.

3.

In a Hydra–Spray

r

 system with a tip installed in

the gun, adjust the pump speed (use the pump air
regulator) to the lowest fluid pressure that will
completely atomize the fluid.

4.

In a circulating system, adjust the back pressure
valve, also.

NOTE: Shaded area indicates continuous op-
eration capability of one heater. Use more heat-
ers if your needs exceed these guidelines.
