General Information

SpitFire 4.0

Section 1-1

his manual contains installation and operation instructions as well as information

T

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 truckmounted carpet cleaning plant has many functions to
perform simultaneously.

• The engine has to run at a consistent RPM.

• The vacuum has to pull air and dirty water back from cleaning site.

• The water pump provides stable pressure at proper water flow for cleaning.

• The chemical has to be injected into the water stream at the right
concentration.

• The heating system must maintain proper heat.

• The vacuum tank must store dirty water until drained.

As you can see, it is not just a turnkey operation with one thing to worry about,

Does it start?

Precautions

lthough this unit has been factory adjusted, it may require additional adjustments

A

to achieve optimum performance, for instance altitude may require carburetor
adjustment and ambient temperatures may require heat control adjustment. When
required, consult an authorized representative.

CAUTION

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.)

CAUTION

ENGINE COOLING: Units employing internal combustion engines must

not be enclosed within a van with doors and windows closed. Excessive
temperatures within the engine will result in premature engine failure
and a compromise of applicable warranty.

CAUTION

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.

WARNING

MOVING PARTS: Never touch any part of the machine that is in mo-

tion. Severe bodily injury may result.

CAUTION

ACID RINSE AGENTS: The increased demand for “clear water” rinsing

results in the need for special care when using these acid based chemi­cals in your equipment. The negative side of these products is the
corrosive effects the acid can have on metals, including swivels, pumps,
heat exchangers, etc.

HydraMaster’s ClearWater Rinse has been formulated to protect vital components.
HydraMaster will not warranty parts that have been damaged from using unprotected
acid products that have obviously caused failures.

CAUTION

HARD WATER PROTECTION: Failure to take appropriate measures to

prevent scale build up can result in system failure and loss of warranty
on affected parts. Test the water in your immediate and surrounding
areas with hard water test strips. Assume all water obtained from wells
is hard. If you are operating in a “Hard Water Area” (3.5 grains or more
per gallon), use a water softening system.

CAUTION

FREEZE PROTECTION: There is often little warning before a cold spell.

Therefore, not protecting this equipment from freezing will result in costly
downtime. 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.

CAUTION

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

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

WARNING

HOT SURFACES: During the operation of this equipment, many sur-

faces on the machine will become very hot. When near the van for any
reason care must be taken not to touch any hot surface, such as heater,
engine, exhaust, etc.

WARNING

HEARING PROTECTION: The Occupational Safety and Health Adminis-

tration (OSHA) recommends the use of hearing protection when a tech­nician is exposed to an average of 85 decibels (this is an average of
exposure over an 8 hour period). This equipment can produce 85 deci­bels to a distance of 10 feet. Please check with your local state agen­cies to see if OSHA standards apply to your application.

NO SMOKING: It is unsafe to smoke in or around the vehicle.

CARBON MONOXIDE: This unit generates toxic fumes. Position the
vehicle so that the fumes will be directed away from the job site. Do not
park where exhaust fumes can enter a building through open doors,

windows, air conditioning units or kitchen fans.

System Operation

he SpitFire heat exchanger system is a highly engineered cleaning plant designed

T

by HydraMaster Corporation. The system utilizes a dynamic heating system com-

prised 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 pre­heater 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
technician. The majority of the water flows to the bypass valve assembly, then
back through the secondary exhaust heat exchanger, and back to the mix tank.

The water demanded by the technician flows from the water pump through the
primary exhaust heat exchanger then out to the cleaning tool.

When the cleaning solution reaches a preset 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.

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 Bulletin
94062 at the end of this manual.)

This provides ‘metal to wood’ mounting rather than ‘metal to metal’, provides insula­tion and makes an attractive van interior. Astroturf should be color-keyed to the van
interior. See Figure 1-1 for correct placement of the plywood flooring.

Materials Needed:

1. Two sheets of 4 x 8 x s” exterior plywood

2. One 6' x 12' piece of commercial Astroturf

3. Sixteen 12” sheet metal screws

4. One quart marine adhesive (optional)

5. One staple hammer with 2” staples

PLACEMENT OF UNIT IN VEHICLE

There are two recommended unit placements:

SIDE DOOR:
Most installations are 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 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
the rear door due to the height of the van bed.

Ensure that the machine is well secured to the floor of the van with the
hardware supplied. A sudden or crash stop will cause the machine to
rocket forward! Protect yourself and the machine. SECURE IT!

WARNING

It is recommended by the manufacturer that the exhaust from the front
of the machine be vented down under the truck to prevent carbon
monoxide from entering the job site. Always park the truck so the
exhaust is blowing away from the job site.

The manufacturer also recommends the installation of aluminum vents
in the truck roof to allow heat to escape..

WARNING

Never operate this machine with a portable gas can inside the truck.
Doing so increases the risk of a fire or explosion.

Mount a fire extinguisher just inside the rear or side door for emergencies

WARNING

Do not use a portable propane tank inside of the truck or van. It is
dangerous and illegal in most states.

WARNING

Transportation in a vehicle of any vented fuel container that presently
holds or has ever held a flammable liquid is strictly forbidden by Hydra­Master Corporation and by federal and state regulation.

Local Water Precautions

SpitFire 4.0

Section 1-19

he quality of water varies greatly. Many areas have an excess of minerals in the

water which results in what is commonly called “hard water.” These minerals

T

tend to adhere to the insides of heater coils and other parts of the machines causing
damage and a loss of cleaning effectiveness. This influences the reliability and effi­ciency of equipment in direct proportion to the level of hardness.

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 the reliability of the machine.

To validate a machine’s warranty, HydraMaster requires that all machines operating in
designated ”Hard Water Areas” (3.5 grains or more per gallon) be fitted with a water
softening system or a properly installed magnetic-type de-scaler must be used and
maintained. Periodic de-scaling or acid-rinsing alone is not adequate in these areas.

HydraMaster does not recommend any particular type or brand, however the rela­tive effectiveness of some types of magnetic de-scalers or softeners may require
additional periodic use of de-scaling agents.

HydraMaster also recommends, in the strongest possible terms, that machines in all
areas be fitted with a water softening system for improved operation and reliability.

HydraMaster has included five hard water test strips with your machine. These

can be used to test the water in your immediate and surrounding areas as they can
vary greatly. Assume all water obtained from wells is hard.

CAUTION

Failure to take appropriate measures to prevent scale build up can
result in system failure and loss of warranty on affected parts.

HARD WATER AREA MAP

The following map defines areas in the United States which compromise fluid re­lated components such as hoses, fittings, heaters, pumps, valves and water cooled
engines. For other countries, hard water area maps can be obtained from geological
societies.

WATER SOFTENER

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 32 grains per gallon. Failure to use a water softener in
these areas will invalidate the machine’s warranty. 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.

The relatively low cost of a water softener service is more than made up for by an
increased life of machine parts, reduced chemical costs and continued cleaning
efficiency. The water softener will also increase the effectiveness of the cleaning
chemicals, 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: If the
softener will treat 900 gallons of water and 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.

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. These must be processed before 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.

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
simultaneously to the cleaning operation.

The hidden benefit of this process is that the technician does not have to stop his
cleaning to empty the recovery tank. HydraMaster makes an A.P.O. System avail­able which can be ordered with new equipment or installed later.

The penalties for noncompliance can be serious. Always check local laws and
regulations to be sure you are in compliance.

our mobile carpet cleaning plant has been engineered using the latest and most

Y

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 buildup 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.
The negative side of these products is the corrosive effects the acid
can have on metals, including swivels, pumps, heat exchangers, etc.

HydraMaster’s ClearWater Rinse has been formulated to protect vital components.
HydraMaster will not warranty parts that have been damaged from using unprotected
acid products that have obviously caused failures.

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 of “clean streaks,” fiber
shrinkage, brown-out and longer drying periods.

OVER-WETTING

Over-wetting is annoying to all concerned, and sometimes leaves a bad impression
of the cleaning process used.

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.

Operating Instructions

SpitFire 4.0

Section 3-1

START UP

1. Perform daily and periodic maintenance as specified in this Owner’s Manual.

2. Connect all required hoses.

3. Connect the cleaning tool to the length of hose required to perform

the cleaning.

4. CAUTION: Mix tank must be full prior to ignition.

5. Place the throttle in the ‘Slow’ position. This is approximately 1800 RPM.

6. Start engine (choke as required).

NOTE: If the engine will not start depress the oil pressure bypass switch

and hold until the engine begins running.

Allow the engine to run for 3 to 5 minutes. Then increase the engine RPM
to ‘Fast’ for normal carpet cleaning. This is approximately 3000 RPM.

7. 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.

8. Run the machine for several minutes under load (8 to 10" HG) until your

desired temperature is achieved.

9. Commence cleaning operation.

SHUT DOWN

1. Flush clear water through the chemical system for 10 seconds. Turn off
chemical flowmeter.

2. Cool the machine by spraying the cleaning wand into the vacuum hose for

three to five minutes. The chemical will be flushed from the unit, hoses
and cleaning tool.

NOTE: If the machine is not properly cooled, the mix tank can overflow.

3. Remove the vacuum hose.

4. At this time, the blower should be lubricated with an oil based lubricant.

NOTE: If freeze guarding is necessary, perform the freeze guard procedure at

this time.

5. Throttle the machine down.

6. Turn the machine off.

7. Drain the mix tank.

8. Drain the vacuum tank. The vacuum filter should be cleaned prior to

mobilization of the van.

NOTE: In accordance with the EPA, state and local laws, do not dispose of

waste water into gutters, storm drains, streams, reservoirs, etc.

FLOOD DAMAGE WORK FOR STANDARD SPITFIRE

CAUTION

When using equipment for flood damage, you must have a fresh water
source hooked up at all times to allow a cold water source into the
machine. This will prevent overheating during long periods of vacuum
recovery.

Exhaust Diverter System

he Exhaust Diverter System consists of two components; the diverter valve and
the pump clutch. The diverter valve directs the flow of the exhaust through the

T

triple heat exchanger or directly out of the machine via the diverter exhaust muffler.
The pump clutch allows the pump to be turned on and off through a switch. This will
enable the machine to be used for flood extraction without the need for an inlet
garden hose connected to the machine. Thus preventing excessive filling of the
recovery tank through the temperature control system.

The SpitFire can run in two different modes:

Cleaning Mode

To run the machine in Cleaning mode:
Push in the heat exchanger bypass lever. It is not necessary to turn the pump clutch
switch to the “ON” position due to a micro-switch that turns the pump clutch on
automatically.

Note: This means that the pump clutch cannot be manually turned off when running
in this mode.

Flood Damage Mode

To run the machine in Flood Damage mode:
Pull out the heat exchanger bypass lever. Turn the Pump Clutch to the “OFF” posi­tion.

CAUTION

HOT SURFACES: When the machine is being run or after it has been

shut down, caution should be used around the muffler and the exhaust
diverter surfaces as they become hot during operation

WARNING

Do not use excessive force when engaging and disengaging the heat
exchanger bypass lever. This may cause damage to the exhaust
diverter.

WARNING

In order for the valve to operate properly, it should periodically be
engaged and disengaged.

Freeze Guard

SpitFire 4.0

Section 4-1

VACUUM FREEZE GUARD PROCEDURE:

To freeze guard your machine:

1. Start the machine.

2. Spray all of the water out of the system until the engine stops.

3. Add a half gallon of 50/50 antifreeze and water mix to the chemical
mix tank and draw the antifreeze into the flow meter.

When using the recirculation kit (part no.
078-058), fill a third of the mix tank with

a 50/50 antifreeze mix. Verify that the
upper float is not lying horizontal, but
floats below.

Attach the recirculation fitting provided
in the kit to the garden hose quick
connect (see illustration to right) and this
combination to the front of the machine.

Attach one section of female/female solution hose to the outgoing solution
fitting on the front of the machine and the other end to the garden hose and
recirculation fitting combination that is attached to the front of the machine(or
as many sections as you want, if you wish to freeze guard your hoses).

4. Start the machine. Allow it to run for 2 to 3 minutes.

With the recirculation kit, skip ahead to step 6.

5. Remove the quick connect fitting from the end of the garden hose.
Attach the garden hose quick connect to the machine. Using a vacuum
hose attached to the recovery tank, vacuum the water out of the
garden hose quick connect.

For machine parts lists, please call HydraMaster Customer Service at 1-425-775-7276

6. Spray the antifreeze and water mix out of the machine and into a container
to reclaim the solution. Run the machine until it stops.

NOTE: The reclaimed antifreeze solution may be used 3 times before being

discarded.

NOTE: To freeze guard hoses and wand, perform the above step with all the

hoses and wand attached.

The machine is now freeze guarded. Remember to flush antifreeze from the system
prior to carpet cleaning.

Recovering Antifreeze For Re-use:

Before cleaning with the machine again, flush the remaining anti­freeze solution from the system into a sealable container so that it
may be used again. To do this, spray water through the hoses and
wand until all signs of antifreeze are gone.

CAUTION

One manufacturer of antifreeze cautions: “WHEN DISPOSING OF USED
ANTIFREEZE COOLANT: Follow local laws and regulations. If required,

dispose at facilities licensed to accept household hazardous waste. If
permitted, dispose in sanitary sewer systems. Do not discard into storm
sewers, septic systems, or onto the ground.”

WARNING

This warning appears on the label of one brand of antifreeze: “HARM­FUL OR FATAL IF SWALLOWED. Do not drink antifreeze coolant or

solution. If swallowed, induce vomiting immediately. Call a physician.
Contains Ethylene Glycol which caused birth defects in animal studies.
Do not store in open or unlabeled containers.

“KEEP OUT OF REACH OF CHILDREN AND ANIMALS.”

Vacuum System

SpitFire 4.0

Section 8-1

he vacuum pump in this machine is commonly referred to as a ‘positive dis-

T

placement ‘lobe’ type blower. The performance and life of this unit is greatly

dependent on the care and proper maintenance it receives.

Because of the close tolerances between the lobes and housing of the vacuum blower,
solid objects entering the inlet will damage the internal lobes, gears, bearings or drive
system.

To prevent this, a stainless steel filter screen has been placed at the vacuum inlet
inside the vacuum recovery tank. This stainless steel screen is ‘finger’ tight and
should be removed for cleaning weekly.

CAUTION

Caution should be used when machine is being run for test purposes and the
vacuum inlet on top of the machine is open.

To protect the vacuum blower from overloading and damaging itself, there is a vacuum
relief system installed on the vacuum tank. When the vacuum tank inlet is completely
sealed off, a maximum of 12 HG will be attained.

At the end of each day, an oil based lubricant should be sprayed into the blower
lubrication port before shutting down the machine. Lubricate the vacuum blower daily
to prevent rust deposits and moisture that will decrease the life of the vacuum blower.

HydraMaster Corporation

7/29/97

Page 8-2 SpitFire 4.0

For machine parts lists, please call HydraMaster Customer Service at 1-425-775-7276

CAUTION

Foam passing through the blower could lead to serious problems.

It is important to keep the vacuum tank foam free.

Read the vacuum blower manual carefully for proper oil change and grease applica­tion. The maintenance log may differ slightly from the manual, but the truckmounted
carpet cleaning machine application is very demanding of the vacuum blower and
therefore it should be maintained more regularly.

CAUTION

The vacuum tank is protected from overflowing by a vacuum tank float kill
switch. The switch is not activated by foam, only by liquid.

VACUUM TANK FILTER BAGS

HydraMaster filter bags are designed to trap lint, sand and dirt that would normally
collect at the bottom of your vacuum tank. The use of these bags, if emptied at the
end of each job, will eliminate the build-up of much of the debris in the tank. The
drawstring top of these bags is designed to be slipped around the incoming dirty
water inlet in the vacuum tank.

been kept to a minimum so as to keep any necessary troubleshooting as easy as

possible.

The entire electrical system operates on 12 volts DC which is provided by a battery.
Battery levels are sustained by a 16 amp alternator inside the engine.

NOTE: When a new battery is installed, check that it is properly charged before
installation or damage to the charging regulator may occur.

The orange wire going from the engine starter solenoid to terminal #5 on the ignition
switch is a fusible link and provides protection to the electrical system in case of

Machine Maintenance

SpitFire 4.0

Section 11-1

o avoid costly repairs and down-time, it is imperative to develop and practice

T

good maintenance procedures from the beginning. These procedures fall into
daily, weekly, monthly and quarterly increments, and are outlined below. All recom­mended maintenance must be performed by competent service personnel.

Important: Record the date and machine hours on the maintenance log.

We have provided a maintenance log for your convenience at the end of this section.

Records of maintenance must be kept and copies may be required to be furnished to
HydraMaster before the warranty is honored.

It is recommended that you affix a copy of the log on the vehicle door near your unit
for convenience and to serve as a maintenance reminder.

OPERATIONAL MAINTENANCE

DAILY:

• Check engine oil level.

• Check high pressure pump oil. Add as necessary.

• Inspect garden hose screen. Clean as needed.

• Visually inspect machine for loose wires, oil leaks, water leaks, etc.

• Lubricate blower with an oil based lubricant through blower inlet.

WEEKLY:

• Inspect vacuum tank s/s filter and filter bag for tears, holes, etc.
Clean, repair or replace as needed.

• One time change of oil and oil filter after first 20 hours of use.

HydraMaster Corporation

9/2/99

• Check pump drive belt for wear.

• Check pump pulleys.

• Check high pressure water lines for wear or chafing.

• Check all nuts and bolts. Tighten as needed.

• Inspect vacuum relief valve. Clean and lubricate as necessary.

• Clean vacuum tank thoroughly with high pressure washer.

• Check wiring for chafing.

• Flush water and chemical system with 50/50 white vinegar solution.

• Change engine oil (every 50 hrs.).

MONTHLY:

• Change oil filter (every other oil change).

• Check engine air cleaner filter. Clean as necessary.

• Remove pressure bypass valve piston plate. Grease plate. Reinstall.

AS REQUIRED: DE-SCALING

Scale deposits on the interior of the heating system can cause a noticeable loss in
heating performance. Deposits of this kind result from hard water deposits, exces­sive chemical use, improper chemicals, etc. The frequency with which de-scaling
procedures are required will vary. If your area has particularly hard water or you see
evidence of deposits in the water system, you may have to de-scale monthly.

9/22/99

HydraMaster Corporation

SpitFire 4.0 Page 11-3

For machine parts lists, please call HydraMaster Customer Service at 1-425-775-7276

To de-scale your system, add an appropriate de-scaler chemical to your mix tank.
Circulate it through the heating system. Let it stand. Flush and repeat as necessary.
Clean all screens and strainers, and check them frequently following de-scaling.

NOTE: If you are using T.M. DeScaler through the flow meter, make sure to run clean
water through the flow meter after this procedure.

To de-scale using the recirculation kit (part no. 078-058), start with an empty mix
tank. Fill a third of the mix tank with T.M. DeScaler. Follow the recommendations
on the T.M. DeScaler label for proportions. Verify that the upper float is not lying
horizontal, but floats below.

Attach the recirculation fitting provided in the
kit to the garden hose quick connect (see illus­tration) and this combination to the front of the
machine.

Attach one section of female/female solution
hose to the outgoing solution fitting on the front
of the machine and the other end to the garden
hose and recirculation fitting combination that
is attached to the front of the machine (or as
many sections as you want, if you wish to de­scale your hoses).

Start the machine and allow it to run for three to five minutes. Do not leave the T.M.
DeScaler solution in the system. Flush the system with clean water and turn the
machine OFF.

OVERALL MACHINE MAINTENANCE

Maintaining the original appearance of your unit is important for two reasons:

1. It represents a big dollar investment for your cleaning business and its appear­ance should reflect that fact. A dirty machine is not professional.

2. Maintenance, troubleshooting, and repair is much easier to accomplish on a
clean, well maintained unit. Regular cleaning of the machine offers you an
opportunity to visually inspect all facets of the machine and spot potential
problems before they occur.

HydraMaster Corporation

9/2/99
