WARNING - to guard against injury, basic safety
precautions should be observed, including the
following:
1. READ AND FOLLOW ALL SAFETY
INSTRUCTIONS.
2. DANGER - To avoid possible electric shock, special
care should be taken since water is present near electrical
equipment. Unless a situation is encountered that is
explicitly addressed by the provided maintenance and
troubleshooting sections, do not attempt repairs yourself,
refer to an authorized service facility.
A dedicated electrical circuit rated with GFI
protection is recommended.
3. Carefully examine the disinfection system after
installation. It should not be plugged in if there is water
on parts not intended to be wet.
4. Do not operate the disinfection system if it has a
damaged power cord or plug, if it is malfunctioning or if
it is dropped or damaged in any manner.
5. Always shut off water flow and unplug the disinfection
system before performing cleaning or maintenance
activities. Never pull on the power cord to remove it from
an outlet. Grab the plug and pull to disconnect.
6. Do not use this disinfection system for other than the
intended use (potable water applications.) The use of
attachments not approved, recommended or sold by the
manufacturer / distributor may cause an unsafe condition.
7. Intended for indoor use. Do not install this disinfection
system where it will be exposed to the weather. Do not
store this disinfection system where it will be exposed to
temperatures below freezing unless all the water has been
drained from it and the water supply has been
disconnected.
8. Read and observe all the important notices and
warnings on the water disinfection system.
9. If an extension cord is necessary, a cord with a proper
rating should be used. A cord rated for less Amperes or
Watts than the disinfection system is rated for may cause
over heating. Care should be taken to arrange the cord so
that it will not be tripped over or accidentally pulled from
the outlet.
1. SAVE THESE INSTRUCTIONS.
2. WARNING: The light given off by this unit can cause
serious burns to unprotected eyes and skin. Never look
directly at a lit UV lamp. When performing any work on
the UV Disinfection System, always unplug the unit first.
Never operate the UV system while the lamp is outside of
the UV chamber.
3. WARNING: The UV lamp inside of the disinfection
system is rated at an effective life of approximately 9,000
hours. To ensure continuous water treatment, replace the
UV lamp annually with the appropriate Aqua Treatment
Services UV lamp. Failure to comply may present a fire
hazard.

Function
Description
The function of this ultraviolet disinfection unit is to provide in excess of 99.9% reduction of all water borne pathogenic
(disease causing) bacteria.
Model PT series have a number code designation correspondent to the maximum gpm
(gallons per minute) flow rate of the unit. I.E.- PT-8 has a maximum flow capacity of 8 gpm.
Applications: PT Units are designed to destroy micro-organisms in water supplies. The Ultraviolet lamp peak radiation
of 254 nanometer wavelength (nm) destroys or inactivates the D.N.A. (deoxyribonucleic acid) which absorbs the
Ultraviolet radiation. PT units meet minimum dosages of 30,000 microwatt second per square centimeter.
MAXIMUM CONCENTRATION LEVELS BEFORE ULTRAVIOLET:
Turbidity.................................5 NTU Hardness..........................................7 gpg
Color.......................................None Iron...................................................0.3 ppm
Manganese........................0.05 ppm pH....................................................6.5 - 9.5ppm
Important Note - Pre-filtration equipment may be required if these parameters cannot be maintained. Flow rate must
not exceed rated capacity of the unit.
The PT series has an unique design with an ultraviolet germicidal lamp housed within a
single quartz sleeve surrounded by a stainless steel pressure chamber. The chamber is fabricated out
of 304 Stainless Steel.
These units come with an ultraviolet lamp designed with four pins at one end and a domed end quartz sleeve to protect
the UV lamp from direct contact with the water and a control box.
The quartz sleeve is intended to be placed through the disinfection chamber and will slightly protrude through the
threaded nipple. The ultraviolet lamp is placed within this quartz sleeve. The U.V. light shines through this specially
designed hard quartz sleeve for maximum disinfection efficiency to meet the requirements for bacteria reduction in
potable water.
The PT Series comes with a site port to visually see that the UV Lamp is on and operating. This is a UV safe glass that
prevents UV light from passing and is safe to viewing lamp operation.
The inlet is located on the bottom of the chamber and the outlet can be located on either side or top side of the UV
chamber dependent upon the installation option selected. A sight Port is provided for safe and easy view of UV
operation. A bracket is secured to the wall and the chamber is held in place by tightening the lock nut to both mounting
bracket and chamber. A UV Control Box operates and monitors the UV Lamp status and provides visual and audible
alarms when the UV lamp is out or requires Lamp replacement.

Installation
GENERAL CONSIDERATIONS FOR ALL
DISINFECTION UNITS:
1. When installing the equipment, it is necessary that the
unit be isolated from vibration, heavy equipment, and
poorly connected piping.
2. Incoming water temperature to the unit should not
exceed 35° minimum to 110° maximum degrees Fahrenheit.
3. The operating pressure should not exceed 100 psi.
4. Before putting the unit into final operation follow
sanitation procedures as outlined in this manual for proper
disinfection. Sanitizing all discharge piping and fittings
with household bleach from disinfection unit to point
of use removes existing contaminants and gives the unit a
“clean start.” Be sure to rinse with U.V. treated water.
5. A proper flow control, included with the unit, must be
used to insure only the designated flow through the unit.
GENERAL PRECAUTIONS TO BE FOLLOWED
AT ALL TIMES:
Only qualified persons or licenced professionals should be
involved in the installation or service maintenance of this
system. Contact PureTest with any questions prior to
working on this system.
1. Always disconnect electrical power to any U.V. unit
before servicing.
2. Under no circumstances should personnel look at a
U.V. lamp in operation (EXCEPT through an external
sight Port lens located on the outside of the unit).
3. U.V. disinfection units must always be properly
grounded. The PT series are always placed after the
pressure tank and any other type of treatment devices (i.e.
softeners, filters).
These units are normally installed in a vertical position in
an enclosed area with good ventilation. Allow clearance of
at least the unit’s length at one end for quartz sleeve and
lamp replacement. Two (2) anchor bolt holes are provided
for proper wall support. Use wall plugs with screws for
sufficient support (not included). A lock nut secures the
mounting bracket to the U.V. chamber.
If your piping system is subject to impulse pressure
resulting in a “water hammer” condition, a surge tank or
other means must be provided to remove this condition;
otherwise, this extreme shock pressure condition may
rupture or fracture the quartz sleeve.
Make all plumbing connections to allow for ease of
service. Be sure to follow all local plumbing codes and
U.V. restriction requirements where specified by local
authorities.
UV CHAMBER & CONTROL BOX MOUNTING
The UV Chamber and Control Box design allows for
several mounting configurations. The Control Box comes
standard mounted to the UV Chamber as shown in Option
A Installation Diagram on Page 5.
STEP BY STEP INSTALLATION:
1. Turn off the water before cutting into the water line.
2. Assess the installation (i.e. type of pipe, size of lines,
etc.) and obtain necessary plumbing fittings for installation.
Inlets and outlets on PT units are 3/4” FNPT and 1”
MNPT. Use Teflon tape on all threaded connections and
avoid over tightening.
Note: The flow control is a press in type. All UV
chambers come standard with a 3/4" FMPT connection
and a 1" MNPT connection on the Inlet / Outlet nipple.
Make sure the rubber part of the flow control is facing
outward from the bottom inlet. Simply hand press or
slightly tap in the flow control until it sits on the inside
ledge of the machined bottom inlet. (see Installation
Diagram on page 5)
3. Using the mounting bracket provided, secure unit to
wall, or other surface. Make sure to allow enough room
to install, replace, and clean the quartz sleeve and lamp.
Installing a water shut-off valve before and after the unit
is recommended to make servicing easy.
4. After mounting, install quartz sleeve, and O-Ring, per
Quartz Sleeve instructions on Page 8. Turn on the water
slowly, check for leaks, and repair as needed prior to full
service operation.
5. After the unit is full of water, plug it into at GFI
protected and grounded 110V outlet. Observe operation
through the safety sight Port. The lamp will show a bright
blue glow. If any problems are noted, consult trouble
shooting guide.
UV CONTROL BOX START UP PROCEDURE
Make sure the UV lamp is inserted per instructions into
the quartz sleeve and UV chamber. Then plug the UV
lamp into the lamp connector. Plug the electrical control
box into a 120volt wall plug outlet.
