Introduction

CrossFire 3.7 section 1-1

his manual contains installation and operation instructions as well as

information required for proper maintenance, adjustment and repair of this unit. Since the first and most important part of repair work is the correct diagnosis of the problem, component manual troubleshooting charts have been included for your convenience.

Unlike a garden tractor, lawn mower or cement mixer, all having one or

two functions to perform, the truck-mounted carpet cleaning plant has

many functions to perform simultaneously.

F The engine has to run at a consistent RPM. F The vacuum has to pull air and dirty water back from cleaning

site.

F The water pump provides stable pressure at proper water flow for

cleaning.

F The chemical has to be injected into the water stream at the right

concentration. F The heating system must maintain proper heat. F The vacuum tank must store dirty water until drained.

As you can see, it is not just a turn-key operation with one thing to worry about, Does it start?!

System Operation

CrossFire 3.7 Section 1-3

he CrossFire heat exchanger system is a highly engineered cleaning

plant designed by HydraMaster Corporation. The system utilizes a dynamic heating system comprised of three separate exhaust heat exchangers for capturing “free heat. ”

The water flow is as follows:

Water is fed into the machine under tap pressure. It flows through one pre-heater and then is automatically combined with a cleaning solution as it enters the mix tank. The solution is then picked up by the high pressure pump and pressurized to the desired level. The water then splits flow, as demanded by the operator. The majority of the water flows to the by-pass valve assembly, then back through the secondary exhaust heat exchanger, and back to the mix tank.

When the cleaning solution reaches a pre-set high temperature, it is

released from the system and directed to the recovery tank. Then cool

water enters the system to regulate the temperature.

As there is no guess work in the manufacture of these highly advanced cleaning plants, there must be none in preparing it to get the job done in the field. It is the purpose of this manual to help you properly understand,

maintain and service your cleaning plant. Follow the directions carefully and you will be rewarded with years of profitable, trouble-free operation.

It is imperative that no section be overlooked when preparing for operation of this equipment.

van witha heavy-duty suspension package. The van should have 3/4

ton capacity.

TRUCK PREPARATION

The manufacturer recommends the installation of plywood flooring, covered with polypropylene backed astroturf (do not use rubber-backed), in the vehicle prior to installation of machine.

CAUTION +

Be cautious when drilling any holes through the van floor, Many vans have critical components mounted directly below

the van floor that could be damaged by a misplaced drill bit.

(See product Support Bulletins 92102,

the end of this manual. )

This provides a metal-to-cushion mounting rather than metal-to-metal,

insulation and makes an attractive van interior. The astroturf should be color keyed to the van interior.

Materials Needed:

1. 2 sheets 4x8xYs” exterior plywood

2. 6’xI 2’ piece of commercial astroturf

3. 16- 1 %” sheet metal screws

4. 1 quart marine adhesive (optional)

A, SIDE DOOR: 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.

B. REAR DOOR: Although this location partly limits working access, it does direct the noise away from the cleaning site. Some cleaners in the colder areas prefer this location because it puts the weight over the rear wheels for better traction in ice and snow. Rear mounting requires the unit to be slid to the right side as far as possible. This 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). Also, it is physically easier to load the unit into

Cleaning efficiency and equipment life is increased, chemical use decreased, and the appearance of cleaned carpets enhanced when water softeners are incorporated in hard water areas. The manufacturer strongly urges the use of water softener units in areas exceeding 3 1/2 grains per gallon, Using a hard water area map as a reference, determine the quality of water in your area and take action immediately, if necessary.

Reports from several of our machine users commending the results of the use of water softeners in conjunction with their machines prompts us to recommend the procedure to everyone in a “hard water” area.

HydraMaster Corporation

4/13/95

CrossFire 3.7

The relatively low cost of a water softener service is more than made up for in the increased life of machine parts and continued cleaning efficiency. The water softener will also increase the effectiveness of the cleaning chemical being used and, therefore, less chemical will be needed.

Contact a water softener distributor in your area for information on the

rental of a simple water treatment unit to carry in your truck. Be sure to change the water softener in accordance with the capability of the softener, For example: the machine uses an average of 30 gallons per hour, for an average of 5

hours a day, this equals 150 gallons per day. In 6 days the machine would use 900 gallons of water. Therefore, the softener would need to

be changed every 6 working days for maximum softening.

If the softener will treat 900 gallons of water and

WASTE WATER DISPOSAL ADVISORY

There are laws in most communities prohibiting the dumping of recovered

“gray” water from carpet cleaning in any place but a sanitary treatment system.

This cleaning rinse water, recovered into your unit’s vacuum tank, contains materials such as detergents. being safe for streams, rivers and reservoirs.

IN ACCORDANCE WITH THE EPA, STATE AND LOCAL LAWS, DO NOT DISPOSE OF WASTE WATER INTO GUTTERS, STORM DRAINS, STREAMS, RESERVOIRS, ETC.

In most cases, an acceptable method of waste water disposal is to discharge into a municipal sewage treatment system after first filtering out solid material such as carpet fiber. Access to the sanitary system can be obtained through a toilet, laundry drain, RV dump, etc. Permission should first be obtained from any concerned party or agency.

These must be processed before

HydraMaster Corporation

4/’13/95

CrossFire 3.7

One disposal method which usually complies with the law is to accumulate the waste water and haul it to an appropriate dump site. Another solution to the disposal problem is to equip yourself with an Automatic Pump-Out System. These systems are designed to remove waste water from the extractor’s recovery system and actively pump the water through hoses to a suitable disposal drain. Properly designed, they will continuously monitor the level of waste water and pump it out

our mobile carpet cleaning plant has been engineered using the latest

and most sophisticated technology available to produce the finest carpet cleaning results possible. Despite this, however, it remains only a tool of the carpet cleaning trade, and it can produce only as good a job as the person operating it.

PRECAUTIONS

There are no short cuts to good carpet cleaning. it requires time, cleaning

knowledge and the use of good chemicals. Therefore, the manufacturer recommends the use of spotting agents and traffic lane cleaners, as required, prior to the actual cleaning of carpeting,

The use of some chemicals through your mobile carpet cleaning plant can

seriously damage the internal plumbing, high pressure pump and heater.

These harmful chemicals include concentrated acid (see the pH chart at

the end of this section), solvents, and some paint, oil, and grease

removers with a high concentration of solvents.

The manufacturer recommends only the use of chemicals containing rust and corrosion inhibitors and water softening agents to prevent chemical build-up which may lead to component failure and warranty invalidation.

+ CAUTION +

The increased demand for “clear water” rinsing results in the need for

special care when using these acid based chemicals in your equipment,

CLEANING STROKE PROCEDURE

Purpose: To eliminate excess moisture remaining in the carpet fiber and the sawtooth appearance which results from diagonal movement of the

cleaning tool on all types of carpet.

Procedure: Always move the cleaning tool in smooth, forward and

backward strokes. Apply slight pressure to the forward stroke while the

solution is injected into the carpet. When extracting (drying), apply firm

pressure on the forward stroke to ensure a positive “lock” for the vacuum

and minimize the “hopping” effect resulting on carpet that is not smooth.

During the forward and reverse strokes, movement to the right or left

should only be accomplished at the extreme rear of the stroke.

Overlapping is also important to ensure even application of solution and

prevent saturation when cleaning wand is stopped twice at the same

point at the rear of the cleaning stroke. This is illustrated at the end of this section.

Failure to adopt this procedure can result in increased chance

THESE ARE SEVERAL AREAS THAT WILL CAUSE OVER-WETTING

1. Too few vacuum strokes or improper saw-tooth vacuum strokes as

shown in the following illustration.

2. Obstructed, cut or kinked hoses.

3. Vacuum tank drain valve left partially open,

4. Clogged vacuum blower filter or vacuum tank lid not sealing properly.

5. Cleaning a heavily foam-saturated carpet without defoamer. (We recommend crystal type. )

Spray the wand to void all air from the system. When the mix tank begins a fill cycle, the chemical flowmeter may be adjusted to your desired setting. Set your cleaning pressure at 300 PSI. NOTE: A chemical flowmeter set at 5 GPH is a 1 to 30 mix ratio and 10 GPH is a 1 to 15 ratio. When the flowmeter is set at 10 GPH, you will be using what most chemical manufacturers recommend at 5 GPH.

Run the machine for several minutes under load (8 to 10“ HG) until your desired temperature is achieved.

Precautions

CrossFire 3.7 Section 3-3

Ithough this unit has been factory adjusted, it may require additional

adjustments to achieve optimum performance, i.e. altitude may require carb adjustment and ambient temperatures may require heat control adjustment. When required, consult an authorized representative.

THROUGH-FLOOR DRILLING: Be cautious when drilling holes through the van floor. Many vans have critical components mounted directly below the van floor that could be damaged by a misplaced drill bit. (See product

Support Bulletins 92102, 94062 and 94063 at the end of the manual.)

ENGINE COOLING: Units employing air cooled engines must not be enclosed within a van with doors and windows closed.

temperatures within the engine will result in premature engine failure and

a compromise of applicable warranty.

LEVEL OPERATION: During operation, van or trailer must be parked on level ground not to exceed + or - 10 degrees. Failure to insure proper leveling may prevent proper internal lubrication of engine, vacuum and/or high pressure components.

FREEZE PROTECTION: Mother nature gives little warning as to her cold spells, Therefore, not protecting this equipment from freezing will result

in costly down-time. Placing an electric heater in the truck or parking the truck indoors will help to insure against freezing, but should not be the

primary method of freeze protection.

EXHAUST SYSTEM: Do not allow flammable material (i.e. oil, fuel, plastic

or wood products) to come in contact with the exhaust system.
