GENERAL
The SUMMIT from American Cleaning Technologies is a completely automatic 3-brush gantry vehicle washer.  It is the most economical choice to wash transit buses, school buses, vans, tractor-trailers, trucks, pick-up trucks and cars. The SUMMIT uses the three brush gantry roll-over principle for wash operations. The wash height of the SUMMIT is 12’-0" or 14’-0".

GANTRY PRINCIPLE
Vehicles to be washed are parked in the wash bay. The SUMMIT makes two passes over the vehicle on floor-mounted tracks, washing during the first pass and rinsing during the second pass.

AUTOMATIC STARTING
The SUMMIT has an automatic starting system utilizing gantry-mounted red and green traffic lights and infrared sensors. When a vehicle enters the wash bay breaking the infrared beam, the washer starts automatically after a specified safety delay.

TOP BRUSH CONTROL
To completely and precisely wash any size vehicle, the SUMMIT uses a programmable logic controller (PLC) with an analog to digital card. This enables exact control of gantry travel and horizontal brush position, and accurate cleaning of the vehicle's front, top and rear surfaces.

SIDE BRUSHES
The vehicle's sides are washed with large vertical rotating brushes as the gantry travels. Compressed air flowing through duplex air cylinders extend and retract the brushes. Flow control regulators maintain smooth constant brush contact with the vehicle.

UL LISTED ELECTRICAL COMPONENTS
The main gantry electrical panel is manufactured from stainless steel. All of the electrical components are listed by Underwriters Laboratories (UL). The electrical system utilizes the finest available standard components, including heavy duty motor starters and overloads, a cycle totalizer, and proximity type limit switches. Full protection is provided for all circuitry through safety fuses and fail-safe wiring design. A programmable logic controller (PLC) controls all operations.

ALL ELECTRICAL OPERATION
The operation of the SUMMIT is all electric, with six electrical motors driving heavy-duty worm gear speed reducers. A chain drive hoists the horizontal top brush. The three brushes and gantry locomotion are directly driven. Electrically operated solenoid valves regulate the water and detergent systems, as well as compressed air control.

WATER AND DETERGENT SYSTEMS
The water system is constructed from schedule 80 PVC pipe. Each nozzle comes with an on-line, easy to remove filter, and is equipped with a check valve that saves water and chemicals. Two complete integral spray arches ensure that the brushes are fully flooded with water during operation, and the vehicle is fully rinsed with clear water. The detergent is injected directly from a 55 gallon drum. A venturi type injector mixes the detergent with the water.

OPERATOR CONTROLS
Although the SUMMIT is automatic in operation, manual controls can be used at any time. The manual controls are located directly on the door of the main electrical cabinet. The top brush and gantry movements are operated by a joystick. The side brushes can be pulled aside with a push button. The main gantry electrical panel has a warning light if an overload is tripped.

PROGRAM SELECTORS
Program selectors are located on the door of the main electrical cabinet . The SUMMIT has four programs: tractor-trailer, bus/truck, para transit vehicle, and car/pick-up truck washes. Other operator controls are the following: selector switches for AUTOMATIC/ MANUAL START and 3-BRUSH/2-BRUSH, push buttons for POWER, STOP TRAVEL, SIDE BRUSHES ASIDE, START WASH and START RINSE, and an EMERGENCY STOP.

BUILT-IN FUNCTIONAL SYSTEMS
AUTOMATIC BACKTRACK - If the top brush becomes entangled in vehicle accessories such as an air-conditioning or refrigeration protrusions, the machine will backtrack until the top brush clears the accessory, then continues washing over the vehicle.
INTENSIFIED REAR WASH – This special feature ensures that the top brush reaches and cleans the rear door regardless of recessed closures.
LENGTH OF WASH/RINSE CYCLES –Washer travel is limited to the length of the vehicle. This saves time, detergents and water.

HEAVY DUTY FRAME CONSTRUCTION
The steel frame, with no less than 11 gauge steel tube used throughout, is completely hot dip galvanized after all welding and machining operations. All machine components, such as wheels and brackets, are electroplated. The waterproof and lockable main electrical cabinet is fabricated from stainless steel and is equipped with waterproof and corrosion resistant manual operator's controls. All bolts, fasteners and rivets are plated or made of corrosion-resistant materials.

THREE FULL LENGTH BRUSHES
All three brushes are composed of 12" brush segments. Each of these segments uses cross-shaped cold processed polyethylene filaments mounted in a rubber core. The segments are attached to the 4 ¾" extruded aluminum brush shaft with self tapping screws. The side brush diameter is 40". The top brush diameter is 52" for the center segments and 54" for both end segments.

EASY INSTALLATION
The SUMMIT's compact frame allows installation in narrow wash bays and outdoors. A standard electrical connection, compressed air and city water is all that is required. These services are carried to the SUMMIT via a wall mounted festoon system.
