Use caution when drilling any holes through the van floor. Many vans have critical
components mounted directly below the vehicle floor that could be damaged by
a misplaced drill bit.
LOCATING THE BOXXER 423S IN VEHICLE
There are two recommended entry points on the vehicle for the Boxxer 423s installation:
the side door or the rear doors.
Most installations are through the side door. This provides rear access for accessories
and hoses as well as unobstructed access to the component/working side of the machine,
thus making it a bit easier to perform maintenance and/or repair without removing the unit
from the truck.
Rear mounting requires the unit to be slid to the right side as far as possible Although
installing the Boxxer 423s through the rear door partly limits working access, it does direct
the noise away from the cleaning site.
In addition, rear mounting not only provides adequate working space on the component
side of the unit but also improves weight distribution inside the van (engine and component
weight line up over drive shaft). Some cleaners in colder geographical areas prefer this
placement for better traction in ice and snow. Also, it is physically easier to load the unit
into the rear door due to the height of the vehicle bed.
Secure Installation
No matter how the unit is installed, check to see if the Boxxer 423s is properly secured to
the floor of the van with the hardware provided. This safety measure will ensure that the
machine will not slide inside the van. See Figure 2-2 for the correct installation.

OPERATING THE BOXXER 423S IN HOT WEATHER
HydraMaster recommends the following steps when operating the Boxxer 423s during
periods of hot weather (95º F or higher). This will help ensure that your Boxxer 423s
continues to run at 100% capacity during even the hottest days.
1. A minimum of 9” (22.9 cm) of clearance is required on both sides of the Boxxer
423s, when installed. Ensure that additional equipment or other materials are not
stored at the sides or on top of the Boxxer 423s. Unobstructed airflow around the
unit is critical for cooling the engine and other components.
2. For side-door vans with “barn doors”, open the doors as wide as their construction
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.
3. Provide cross-ventilation. When possible, keeping the rear doors open while the
Boxxer 423s 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.
4. Consider adding powered roof vents to the vehicle (if not already installed). These
vents can significantly reduce interior temperatures and will result in much cooler
operation.
