f.
The first time you use the heater,
operate it without using the heater ATC
(72). Check the temperature gauges
regularly during the day and adjust the
fluid temperature as needed. This will
help you determine the right ATC range
for the type of foam chemicals you are
using.
g. The second day of operation, set both
heater ATCs to MED.
normally provides enough ambient
temperature compensation.
NOTE: You will quickly learn what ATC range is
the best for your foam chemicals. The chart in
Figure 16 can help you determine how wide a
range in temperature you need to maintain the
proper fluid temperature and viscosity for good
foam development.

6. Spray the gun for several seconds, in cold
weather, to warm the fluid nozzle.
Open the RES side needle valve first to prevent
damage to the nozzle.
Pressure Relief Procedure
Always relieve the fluid pressure in the sprayer
and hoses before checking or adjusting any part
of the system or any component, to reduce the
risk of serious bodily injury, including fluid
injection, splashing in the eyes or on the skin, or
injury from moving parts or electric shock.
1. Engage the spray gun trigger safety latch.
2. Shut off the air to the feed pumps.
3. Turn off the air to the proportioning pump.
4. Close the gun manifold needle valves.
5. Disengage the trigger safety latch, trigger the
gun, to relieve pressure, and engage the
trigger safety again.
6. Open both fluid filter drain valves, having a
container ready to catch the draining fluid.
7. If you are working on any part of the heater,
shut off the main electrical power to the
heater.
Maintenance
Keep the displacement pump wet-cup 2/3 full of
IPO at all times to help protect the pump packings.
Refer to the separate instruction manual for each
system component for routine maintenance and
repair procedures.
