Solution System

Functional Overview

The Adphibian, AX 651 Multi EDS and AquaPLUS models have a solution tank capacity of 20 gallons (76 liters). All
models use one right rear tank fill opening. A flexible clear hose on the side of the solution tank indicates the solution
level, and is used to drain the tank for system maintenance.
See Figure 5. A serviceable Solution Filter (C) is plumbed into the manual Solution Shutoff Valve (B) outlet to keep
debris from entering the solenoid valves.
Electrical Solenoid Valves (L1 and L2) switch the solution flow to the Maintenance/LIFT (D) and Restoration (E) spray
nozzles on and off. The M1 solution pump (A) on the machine chassis controls the needed flow volume demand to the
nozzles. (See the electrical diagram in Figure 6.) The electrical circuit that turns on (energizes) the solenoid coils and
solution pump is activated through the (A1) control panel's solution switch button input and the FOR / Reverse. (A2)
Speed Controller voltage output signals.
