MESSAGE FROM THE CORPORATE OFFICE

Congratulations on the purchase of your new Thermax DV12
Professional Hot Water Extraction Cleaning System! In 1971,
Thermax founder Carl Parise developed the world’s first UL
approved carpet steam cleaner for the U.S. market, and has
since produced over 500,000 units sold worldwide. We have
adopted our own brand name, Thermax, which is rapidly
becoming a household name, synonymous with the industry.

In an industry full of competition and choices, we at Thermax
are grateful for your wise choice of the Thermax DV12, and

Todd Walker, CFO,
Jason Davis, CEO,

and Mark Rodie, COO

we look forward to a lasting relationship as we service all
your business needs.

Your new DV12 is a high performance workhorse. When
maintained and operated in accordance with this owner/
operator manual, it will give you years of quality service.

For over three decades, Thermax has produced fine quality,
portable, hot water extraction cleaning systems for the
home, hotel/motel, auto detail, janitorial, as well as other
commercial markets. The Thermax CP3 portable rental
system pioneered the do-it-yourself rental steam cleaner*
market, introducing America to a new way to clean carpets.

Our company and staff subscribe to the philosophy that our
relationship with you the customer doesn’t end with the sale,
it only begins. If there is any area in which we can be of
service, please call the Thermax Customer Support Center
at 1-888-764-3700.

Thank you for joining the ever-growing family of Thermax
owners. Here’s to many years of use and, most importantly,
here’s to a healthier indoor environment.

*Steam cleaning is the generic technology used to describe
the hot water extraction process of cleaning carpet.

INSPECTION UPON DELIVERY

Carefully unpack and inspect the Thermax DV12 and be sure all components
ordered are included. Orders might be packed in more than one box.

NOTE: Contact the carrier immediately regarding any damage incurred during
shipping as it is your responsibility to file a damage claim with the carrier.

IMPORTANT SAFETY INFORMATION

1) Do not leave plugged in while unattended.

2) Do not operate heater while solution tank is empty.

3) To prevent the possibility of electrical shock, always unplug the system from

the main power source before physically inspecting or attempting to repair

the system.

4) Inspect system daily, especially when used by someone else. Inspect for

damaged components such as loose wires, frayed cords, missing ground

pin, etc.

5) Only operate system when it is properly grounded. Improper grounding could

result in serious or fatal shock!

6) When operating the system around water, during flood restoration, etc.,

always outfit yourself properly with rubber-soled shoes or rubber boots and

do not set system in standing water.

7) To keep from voiding your warranty, use only those cleaning solutions

manufactured by Thermax and never use solvent based products.

8) After use, always thoroughly rinse and clean both recovery and solution

tanks. If using recovery tank to store hoses, or other miscellaneous items,

always clean items before storing them in tanks.

9) Do not operate solution pump dry.

10) Do not store where temperatures drop below freezing, as this may damage

the pump.

11) Always use defoamer in recovery tank to prevent the motor from being

damaged from overfoaming.

12) Extension cord should have a minimum rating of 12/3 (#12 cord). Extension

cord should not exceed 50 feet.

13) Never open up the system when there is water in either the solution or

recovery tank, remove the solution and waste water first.

SET-UP PROCEDURE

1) Pre-mix cleaning solution as required for specific application in a five gallon (19 liter) pail. Pour pre-mixed solution through solution fill
hole of system (page 3, #2).

NOTE: This system has a built-in solution heat maintenance feature, start with hot water if possible. Hot water is hygienic and maximizes

cleaning potential.

2) Add appropriate amount of defoamer to the recovery tank (page 3, #3).

3) Connect end of the vacuum hose to the vacuum inlet connector (page 3, #10).

4) Connect male end of the solution hose to female quick-connect coupling (page 3, #9), and female end of solution hose to the male end
of the cleaning wand.

5) With solution tank full and vacuum and solution hoses properly connected, plug main power cord (page 3, #5) into properly grounded
outlet.

NOTE: Plug the cord into an outlet that will be out of the way of the cleaning path, ideally a 20 amp circuit when available.

6) Your system is now ready for operation.

NOTE: The preheat setting can be activated by switching to the “ON” position. This setting activates 1800 watts of heating power. When

the solution reaches approximately 175° F, it will automatically shut off as indicated by the preheat indicator light turning off on the switch
panel. The preheat system will turn on and off as necessary to maintain 175° while preheat is in the “ON” position.

7) Once pre-spray, furniture removal and other carpet preparation is complete, proceed to clean carpet and/or upholstery.

NOTE: Preheat switch can now be activated to “OFF” position. The system is designed so the vacuum or pump switch will not function

unless the preheat switch is in “OFF” position. Pump and vacuum switches may be activated independently or in tandem when preheat
switch is in “OFF” position.

EXTRACTION CLEANING PROCEDURE

1) With solution up to temperature and all hoses attached appropriately, set the preheat switch to “OFF” position, then activate the pump
switch to “ON” position.

2) Turn the vacuum switch to “Single Vac” or “Dual Vac” position.

3) Start in area of the room opposite from where you want to end.

4) Place wand about 4 feet in front of you.

5) Activate the solution spray trigger of wand.

6) Laying down an even spray of solution, pull the wand back towards you slowly.

7) Release the solution spray trigger and move the wand slowly forward over the same area just cleaned to recover additional solution left
behind. Repeat this process several times depending on the degree of carpet soiling then move over the width of the wand, overlapping
slightly to prevent streaking. For best results, work in approximately 4 foot wide sections and always be sure to remove as much solution
from the carpet as possible as this will minimize drying time.

8) When solution tank is empty and needs refilling, shut system down and repeat step 1 of “Set Up Procedure”.

9) Using a 5-gallon bucket, empty recovery holding tank (page 3, #3) by placing the bucket under the drain gate (page 3, #11), lifting the
gate up and shutting the gate when bucket is full. Repeat this process until recovery holding tank is empty.

NOTE: Although the recovery tank will hold approximately 12 gallons and is equipped with an automatic full shut-off feature, empty the

recovery tank at the same time you refill the solution tank.

10) Add more defoamer into the recovery holding tank (step 2 of “Set Up Procedure”).

NOTE: With solution tank full and recovery tank empty, the system is now ready to continue cleaning. Continue the process until cleaning

is complete.
