Scale build up causes serious in the past, a flammable liquid is strictly forbidden by HydraMaster and by federal component damage. Test all water prior to use and use water softening equipment and state regulations.
RESPONSIBILITIES Never allow water to freeze inside the truckmount. Serious component damage Purchaser’s Responsibilities will occur. Perform all freeze guarding procedures outlined in this digital Owner’s • Prior to purchasing a van, ensure that the payload is suitable for all of the equipment Manual.
Page 11

Hard Water Advisory HydraMaster recognizes that any hard water deposits which might occur within the water system of our truckmounts is a serious problem. The precision technology of truckmount heat exchanger systems is intolerant of any foreign material. Hard water deposits will ultimately decrease the performance of the system and are expected to seriously lower Figure 1-1.
Page 14
HydraMaster strongly urges the use of water softener units with the Boxxer 423s in areas exceeding 3.0 grains per gallon.
Although there are many different heavy duty vehicles used for carpet cleaning equipment, the preferable vehicle for a Boxxer 423s installation is a cargo van with a heavy-duty suspension package and a 3/4 HD ton capacity. If a fresh water tank is added, a one ton or larger capacity van is required.
Figure 2-2. Recommended Location of Boxxer 423s in Van 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.
The Boxxer 423s is shipped from the factory with antifreeze added to the solution system. job site. Always park the truck so the exhaust is blowing away from the job site.
ORIENTATION OF FUEL PUMP For proper fuel pump operation and fuel flow, the vehicle’s fuel pump must be installed in a lower position with respect to the fuel tank and in as vertical a position as possible (outlet side up - see Figure 2-3 and Figure 2-4).
HydraMaster’s ClearWater Rinse™ has been formulated to protect vital components. HydraMaster will not warranty parts that have been damaged from using acid products that have obviously caused failures. 3-1: Cleaning Information...
Streaks in the carpet can appear in both clean or dirty areas and normally appear in heavily soiled, light colored carpets. HydraMaster recommends the use of our pre-sprays: Fastbreak™ for residential carpet and Blitz™ for commercial carpet needs. Possible reasons of streaking may include: Clogged or improperly angled spray nozzles.
CLEANING TOOL TIPS Wands With a wand, keep cleaning strokes short, front to back, and run a “dry pass”. After pulling the wand for a strip of 3 or 4 ft long with the solution trigger activated, go back up to the top of the stroke, and make a “dry “ pass [i.e. no solution flowing]. This gives the wand a second chance to pick up the solution on the carpet.

Blower Lube Port Incoming Never clean when the Boxxer 423s is in the IDLE mode. Failure to follow this Fresh Water caution may result in serious component or engine damage. Pull the “THROTTLE” cable all the way out and lock into place.
Uncap the inlet(s) and run the unit for another minute to allow the blower to cool down. Figure 4-3. Boxxer 423s Chemical System Control and Metering If freeze guarding is necessary, perform the procedure at this time. See the Freeze Guarding section of this Owner’s Manual (see page 5-18).
A maintenance log, provided in the Owner’s Guide, must be correctly and completely filled out. HydraMaster may request to inspect the logs before a warranty claim is honored. It is recommended that the log be affixed to the vehicle door near the truckmount for convenience and to serve as a maintenance reminder.
• Check the fuel lines every 250 hours. Repair or replace as needed. • Lubricate the blower lube port with a HydraMaster-recommended lubricant, • Check valve clearance, intake and exhaust 0.004 to 0.006” every 250 hours. P/N 000-087-006.
Use only engine oils displaying the American Petroleum Institute (API) “starburst” certification mark ‘FOR GASOLINE ENGINES’ on the container.

Replace center inlet check valve with modified check valve Servicing Valves on the High Pressure Pump - Figure 5-3. Removing a Valve Remove the valve cap (30 mm) and extract the valve assembly (see Figure 5-1). Modified Check Valve Figure 5-1. Remove Valve Cap and Valve Assembly Figure 5-3.
10. Remove the fasteners retaining the manifold 15. Remove the stainless steel plunger bolt and ceramic plunger from the plunger guide Separate manifold from crankcase (see Figure 5-6). (see Figure 5-9). 16. If the slinger washer is removed, be certain it is re-installed or replaced. 17.
Extracting Seals Replacing the Seal Assemblies With manifold removed from crankcase: Only one seal kit is necessary to repair all the seals in the pump (see Figure 5-12). Use an insertion tool for seal installation Insert proper extractor collet through main seal retainer (see Figure 5-11). Tighten collet and extract retainers and seals.
Re-Installing Manifold To install the intermediate retainers and the low pressure seals: Position the outer plungers at the same position (see Figure 5-16). Insert the brass intermediate retainer into the cavity. Re-install manifold and torque the fasteners in an “X” pattern to 50% of specification Press the new low pressure seal into the brass low pressure seal retainer and install and then retorque to 100% specification (see Figure 5-17 and Figure 5-18).
“OFF.” to remove moisture from the blower. Cap off the inlet(s) to the vacuum tank. Spray a HydraMaster-recommended spray lubricant into the “BLOWER LUBE PORT” for about 5 to 7 seconds while the unit is running. 000-078-058 Uncap the inlet(s) and run the unit for another minute to allow the blower to cool down.
FREEZE GUARDING Freeze Guard Procedure To avoid permanent damage to the truckmount, it is imperative to follow the Freeze Guard With the truckmount turned off and the incoming water line disconnected, open Procedure whenever the possibility of freezing temperatures exists. the water box drain valve on the front of the truckmount.
Page 40
To freeze guard the hoses and wand, perform the preceding procedure with the items to be freeze guarded attached. Always check the freezing level of your reclaimed antifreeze with a glycol tester before reusing. Failure to do so may result in serious component damage. Recovering Antifreeze for Re-Use Attach all hoses and wands which have been freeze guarded to the truckmount.
6 - Water and Chemical System This section describes the Boxxer 423s’ water and chemical systems, and includes the exhaust subsystem. The process starts when fresh water is brought through the front of the truckmount into the water box, as indicated in Figure 6-1. The level of water in the box is maintained by the use of a float valve.
Page 42
Finally, the water joins the chemical where the solution is created (see Figure 6-2). The chemical is pressurized by the HydraMaster diaphragm chemical pump attached to the head of the water pump. This pump pulls the chemical from the chemical, or soap, jug through the chemical flow meter (see Figure 6-3).

Wiring Diagram ELECTRICAL SYSTEM INFORMATION The Boxxer 423s electrical system operates on 12 V DC which is provided by the battery. Battery levels are maintained by a 20 Amp alternator mounted on the engine. When a new battery is installed, check that it is properly charged before installation or damage to the charging system may occur.
