WARNING
Ensure that a ground wire from a proven earth ground is
connected to the ground lug near the input power block
on this machine. Without proper grounding, personal injury
from electric shock could occur and machine malfunctions
may be evident.
MISUSE
Never wash petroleum-soaked rags in machine. This could result in an explosion.
Never wash mechanical parts or automotive parts in machine. This could result in serious
damage to the cylinder.
Never allow children to play on or around machine. Death or serious injury can result if
children become trapped in machine. Do not leave children unattended while machine door is
open. These cautions apply to animals as well.
Always disconnect power and water supplies before a service technician performs any service
procedure. Where applicable, steam supply should also be disconnected before service is
performed.
SAFE OPERATING ENVIRONMENT
Safe operation requires an appropriate operating environment for both the operator and the
machine. If questions regarding safety arise, contact EDRO immediately.
END-USER RESPONSIBILITY FOR ENVIRONMENT CONDITIONS
Ambient Temperature: Temperatures above 120º F (50º C) will result in more frequent motor
overheating and in some cases, malfunction or premature damage to solid state components.
Special cooling devices may be necessary. Increases and decreases in temperature affect
water pressure switches. Every 25º F (10º C) change in temperature will have a 1% effect on
the water level. Water in the machine will freeze at temperatures of 32º F (0º C) or below.
Humidity: Relative humidity above 90% may cause the machine’s electronics or motors to
malfunction or may trip the ground fault interrupter. A corrosion problem may occur on some
metal components in the machine. If the relative humidity is below 30%, belts and rubber
hoses may eventually develop dry rot. This condition can result in hose leaks, which may
cause safety hazards external to the machine in conjunction with adjacent electrical equipment.
Ventilation: The need for make-up air openings for the washer-extractor and other laundry
room accessories such as dryers, ironers, water heaters, etc. must be evaluated periodically.
Louvers, screens, or other separating devices may reduce the available air opening significantly.
