IMPORTANT SAFETY INSTRUCTIONS FOR HANDLING PURASAN® TABLETS AND SOLUTION
WARNING: HAZARD OF DANGEROUS CHEMICAL REACTION
1. Use ONLY Purasan Tablets.
2. DO NOT add any other chemicals or cleaning products to the toilet or the treatment system. aritan C.P. - Cleans
Potties and .C. aritan Concentrate are the only factory-recognized cleaning product that may be used in the
toilet.
WARNING: HAZARD OF SEVERE INJURY
1. DO NOT allow tablets to come in contact with skin, eyes or clothing. If contact occurs, immediately wash
affected area with fresh water. emove and wash any affected clothing.
2. Use a well ventilated area when handling Purasan Tablets. DO NOT breathe dust from tablets - severe damage to
mucous membrane of the respiratory passages could occur.
3. Do not ingest.
4. Follow all cautions and warnings associated with handling of tablets.

PURASAN®
OPERATION, MAINTENANCE AND INSTALLATION INSTRUCTIONS
(Models PST*02 and PST*03 [*specify 12,24,32] Manufactured after September, 2004)
THE FOLLOWING ARE CAUTIONARY STATEMENTS THAT MUST BE READ AND
FOLLOWED DURING BOTH INSTALLATION AND OPERATION
WARNING: Raritan Engineering Company, Inc. recommends that a qualified person or electrician install this product.
Equipment damage, injury to personnel or death could result from improper installation. Raritan Engineering
Company, Inc. accepts no responsibility or liability for damage to equipment, or injury or death to personnel
that may result from improper installation or operation of this product.
WARNING: HAZARD OF SHOCK AND FIRE
Always use recommended fuse or circuit breaker and wire size.
WARNING: HAZARD OF FLOODING - When leaving the boat unattended always be sure seacocks are closed. Any
installation made below waterline should have double hose clamps securing lines. The ha ogen disinfectant is
corrosive to a uminum, copper and stee . The p umbing system must not inc ude any a uminum, copper
or stee fittings, piping or ho ding tanks.
The Purasan is a U. S. Coast Guard Certified Type I Marine Sanitation Device for use on inspected and
uninspected vessels 65 feet and under. It ust be operated within areas that are not declared a Federal No
Discharge Zone (NDZ) by the U.S. Environ ental Protection Agency (EPA). This is applicable for all U.S.
territorial waters inside the three ile li it. Other countries - check with local authorities.
The Purasan is designed for recreational use and acco odates ost arine toilets it can be used with one or,
in so e cases, two toilets. The Purasan is available in 12, 24 or 32 V DC.
The syste consists of a Treat ent tank, Tablet dispenser and Switch panel with cable. A portion of inco ing
water passes over the halogen tablets creating a solution that is then dispensed into the treat ent tank and ixes
with the acerated waste sanitizing it for discharge.

OPERATION
(depends on installation chosen)
Single Button operation -
Both toilet and Purasan are operated by one of the
following options:
Option #1:
Switch Panel
"Push to Cycle" button activates both the toilet
and treatment cycle.
Note: Toilet flush time is set at 10 seconds,
after initial 10 seconds holding the button down
will momentarily flush the toilet.
Option #2:
Toilet Push Button -
Flushing toilet will activate treatment cycle.
Note: Toilet may be flushed as often as neces-
sary, do not exceed recommended flush volume.
Independent Button operation -
1. Press "Push to Cycle" button
2. Flush toilet as often as necessary, do not
exceed recommended flush volume.
Recommended Flush Volume -
Total flush volume must not exceed 1.5 gallons
(5.7 liters) per cycle.
After Toilet is flushed:
Water is diverted to the tablet dispenser and
must rise to the water level line (dotted line)
but no higher.
The Purasan should not be activated again
until the cycle is complete.
How it works -
Each time toilet is flushed an equal amount of
previously treated waste is discharged. The Purasan
does not pump waste out, the flushing action of the
toilet moves the waste through the Purasan.
Water is diverted to the tablet dispenser during the
flush cycle and should rise to the water level line
(dotted line), this creates a solution that drains into
the treatment unit.
The first chamber macerates to reduce particle size
and uniformly mix the waste with injected halogen
solution. The second chamber mixes to ensure
uniform treatment of contents.
When activated both motors come on and run for
the entire cycle of two minutes.

fitting or check valve from water solenoid valve.
Drain tube into a clean plastic container.
4. Carefully remove the small tube at the bottom of
the black “T” fitting. Drain tube into a clean plas-
tic container.
5. Connect Tube removed in step 3 to black “T”
fitting
6a. White “T’ fitting:
Connect tube removed in step 4 to white “T”
6b. Water Solenoid Valve
plug tube removed in step 4
shut off water to valve
drain water from valve, hoses and strainer
7. Take solution collected in plastic container and
pour into toilet bowl. Rinse container and dis-
pose of properly.
8. Flush toilet several more times to dilute solution
and clear it from system.
Treatment Unit
WARNING: DO NOT use anti-freeze of any kind
to winterize the Purasan system.
1. Turn off power and disconnect wires to Purasan
2. Close seacocks.
3. Slowly open crossover plug
Caution: Open plug slowly if treatment tank is at
the lowest point water will spill out
4. Using a pump, remove water from both sides of
the treatment tank through crossover cap.
5. Disconnect and drain hoses.
