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 flow control, included with the unit, must be
installed to insure only the designated flow through the
unit for proper disinfection.
GENERAL PRECAUTIONS TO BE FOLLOWED
AT ALL TIMES:
Only qualified persons or licensed professionals should be
involved in the installation or service maintenance of this
system. Contact PurTest 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.
The Control Box may be removed and mounted on the
wall right next to the UV Chamber as shown in Option B
or C on the installation diagram. (Wall mount screws are
not included).
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.
Upon start up the UV lamp Detector and Timer circuit
board will perform a self diagnostic test. When power is
applied the UV lamp will go on and a circuit board output
check is performed as follows:
Quick Beep
Green LED on, then off
Red LED on, then off
Solenoid / Relay connection on, then off
Pause with beeps
Green LED on = System Check OK, UV System is
operational.
Set the 1 Year Lamp Timer – WITH NEW UV LAMP –
Make sure the control box is plugged into the wall outlet
and the UV lamp is on. Press and hold the reset push
button. A tone that descends in frequency once per
