Operation HIF 690
4.11 Running the Machine
Background The Wacker Neuson Flameless Heaters are designed to safely provide heat
without open flames. Ambient conditions will affect machine performance factors in
many ways. To obtain maximum efficiency, the application area conditions must be
considered along with the desired effect. Use the informatin and guidelines below
to adjust machine parameters in order to obtain maximum system efficiency and to
avoid unnecessary down-time.
Overheat
shutdown
If the engine is not warmed up properly, the CALFLO™ AF could become hotter
than the set-point temperature before the louvers can open to cool the system.
This will result in a machine shutdown.
To avoid this situation, allow the engine to warm up sufficiently before increasing
rpm. See topic Preliminary Checks.
Typical
settings
Most application areas will be efficiently heated using a 170°F (76°C) setpoint. Be
sure to allow a proper engine warm-up period before setting the temperature
controller. See topic Preliminary Checks.
This procedure continues on the next page.
DANGER
Carbon monoxide. Using the machine indoors CAN KILL YOU IN MINUTES.
Exhaust gas contains carbon monoxide (CO). This is a deadly poison you cannot
see or smell. If you can smell the exhaust, you are breathing CO. Even if you
cannot smell the exhaust, you could be breathing CO.
f NEVER operate the machine inside an enclosed area, such as a home, tunnel,
or garage.
f ONLY use the machine outside and far away from windows, doors, and vents.
These openings can pull in exhaust.
f ALWAYS use a battery-powered or battery-backup CO alarm in nearby struc-
tures. Even when you use the machine correctly, CO may leak into nearby
structures.
f If you start to feel sick, dizzy, or weak after the machine has been running, move
to fresh air IMMEDIATELY. See a doctor. You could have carbon monoxide
poison.
