The manufacturer recommends the following steps when operating the
Steamatic 8800 TMU during periods of hot weather (95º f [35º C] or higher). This will
help ensure that your Steamatic 8800 TMU continues to run at 100% capacity during
even the hottest days.
A minimum of 9” (22.9 cm) of clearance is required on both sides of the 1.
Steamatic 8800 TMU, when installed. ensure that additional equipment or other
materials are not stored at the sides or on top of the machine. Unobstructed airflow
around the unit is critical for cooling the engine and other components.
for side-door vans with “barn doors”, open the doors as wide as their construction 2.
will allow. be sure to open the doors beyond their standard “straight-out” position,
if possible, by releasing the stops and putting the doors in their fully extended
position.
Provide cross-ventilation. When possible, keeping the rear doors open while the 3.
machine is running will substantially reduce the temperature inside the van and will
provide a path for cooling air flow. For rear-mount installations, open up the other
doors in the van.
Consider adding powered roof vents to the vehicle (if not already installed). These 4.
vents can significantly reduce interior temperatures and will result in much cooler
operation.
Run the Steamatic 8800 TMU in HoT mode when outdoor temperatures are high. 5.
Running the machine in WARM mode is not “easier” on the machine. In fact, it
cuts the coolant heat exchanger out of the cleaning solution loop, in effect reducing
the engine-cooling capacity. The machine was designed to deliver solution at the
optimum temperature to clean carpets when in the HoT mode. The WARM mode is
intended for delicate materials like upholstery.
