Chapter 1: System Overview
The Puralytics Shield 1500, shown in Figure 4 represents the
state of the art in photochemical water purification.
Five independent photochemical processes act synergistically to
remove organic chemicals, heavy metals, and microbiological
contaminants from process water at flow rates up to 3.9 liters per
minute (up to 1500 gallons per day).
Electrical power is supplied to the unit through a grounded, 3-conductor
male Power Input Module at the electrical end of the unit, as shown in Figure 5. The
power cable supplied with the unit is rated for currents up to 15 A at 120 VAC (8 A at
220 VAC).
Figure 5. Power input module
Figure 4. Shield 1500

Water enters the system through a water input port
and exits through a water outlet port, both located
on one end of the unit as shown in Figure 6. For
proper operation, water must flow into the input port
(bottom) and out of the output port (top).
Reverse water flow through the system will
result in reduced performance and reduced life of
the system.
The Shield 1500 contains an Access Door, as
shown in Figure 7, to allow the user to access the
sump and its 20-inch NanoMesh Cartridge located
within the compartment for maintenance – see
Chapter 7 for details.

Electrical Connections
The electrical power connector on the Shield 1500 is a standard 3-pin
(IEC320-C14) male connector. A 3-conductor power cable with a mating female
connector (IEC320-C13) is supplied with the system. The Shield 1500 is compatible
with supplied electrical AC power at voltages within the range of 100-240VAC RMS
and frequencies within the range of 50-60 Hz.
The fuse shipped in the fuse holder of the Shield 1500 is suitable for operation with
supplied electrical AC power at voltages in the customer’s anticipated range.
Protective grounding of the Shield 1500 is required for safe operation. Ensure
that the wall outlet receptacle is properly wired and earth grounded. DO NOT use a
three-to-two wire plug adapter. DO NOT use a two-wire extension cord or a two-wire
multiple-outlet power strip. Do not modify the supplied power cable in any manner that
defeats this requirement for protective grounding of the Shield 1500.
Pre-Startup Testing
Disconnect power from Shield 1500 and supply water to the input of the
system at a pressure not to exceed 65 psi (4.48 bar, 448 kPa). Flush a minimum of
20 L of clean water through the system. Verify that no water leaks are observed at
the input or output connectors, and that no water leaks from the body of the system.
Chapter 3: System Start-Up
Before connecting power to the system, ensure that the power switch is in
the OFF state (“O” side of rocker switch depressed). Connect a properly grounded
3-conductor cable from a properly grounded power outlet to the system power input.
Switch the system to the ON state by depressing the green indicator side of the
power rocker switch.

Chapter 4: System Operation
The Shield 1500 is designed to operate with a minimal amount of operating supervision
or maintenance, providing the water quality meets input requirements are met (see
Facility Requirements section).
Operating Procedures
1. Make sure the water fittings are connected to Shield 1500 as detailed
under the “Water Connections” section above.
2. Connect electrical power to Shield 1500 as detailed under “Electrical
Connections.”
3. Follow the instructions under “System Setup” to start Shield 1500
operation.
4. Start water flow at a rate of at least 1.3 L/min and not more than 3.9
L/min. Simultaneously depress the red air release button at the top of
the unit until air stops coming out at the button.
5. Allow at least 15 minutes of discharging to waste to allow the UVC lamp
to warm up. This should also be sufficient time to remove the worst air
bubbles from the 20-inch NaonMesh Cartridge. If significant air bubbles
are still present discharge to waste until most large air bubbles have
been flushed from the system to ensure peak performance. Turning up
the flow rate will facilitate air flushing.
6. Adjust water flow rate to the desired rate. Lower rates will facilitate
slightly higher levels of treatment.
Maintenance Items
The following ordinary maintenance schedule when operating the Shield 1500
continuously would consist of:
• Cooling Fan check; UVC quartz sleeve cleaning
Recommended quarterly. See Chapters 5 and 6 for details.
• 20-inch NanoMesh replacement:
About annually.* See Chapter 7 for details.
• UVC lamp replacement:
About annually.See Chapter 6 for details.
• LED replacement:
About every 4 years.* Contact Puralytics for replacement after this
time has passed.
*If not operated continuously these can all be maintained at a proportionately
lower frequency.

Chapter 5: Cooling Fan Maintenance
Introduction
A cooling fan is provided on the underside of the unit to maintain optimal power supply
to the LEDs by the LED power supplies. The fan operates whenever the unit power is
on providing an auditory reminder that the unit (and UVC lamp) is powered. Air is pulled
from the back/below, is blown over the power supplies and exits through a grid of holes
on the bottom-center as well as slots on either side of the bottom.
Inspection
Always listen for the fan. Any changes of pitch could indicate obstruction of the fan inlet
grille. Quarterly, access the bottom of the unit (if situated on a counter, just tip the unit
backward slightly) and look for any lint or other obstruction of the fan inlet grille.
Maintenance
Anytime that there is material on the fan grille, remove it with a brush and/or
compressed air.

Chapter 6: UVC Lamp Use and Maintenance
Introduction
The UVC Lamp is designed to operate with a minimal amount of maintenance, providing
the water quality meets input requirements (see Facility Requirements section). The
UVC Lamp provides a boost in microbial disinfection on top of that already provided by
the 20-inch NanoMesh Cartridge.
Ordinary maintenance consists of;
• Cleaning or replacing the quartz sleeve.
• Lamp replacement – recommended every 10,000 hours of operation
(approximately 60 weeks of continuous service independent of operational flow).
More frequent replacement is recommended if the unit is turned on and off
frequently.
Always disconnect the water supply and completely drain the system if it will be
subjected to temperatures below the freezing point of water.
Inspection
1. Regularly inspect the UVC Lamp:
• An LED indicator light, located on the end opposite of the easy off end cap
(depicted in Figure 14), provides visual indication of germicidal lamp operation
and should be illuminated during the Shield 1500 operation.This indicator light
does not, however, indicate the level of ultraviolet intensity or transmission
through the water.
• Quarterly cleaning of the quartz sleeve is recommended for optimal light delivery.
2. To ensure proper operation of the UVC Lamp, regular biological testing of the
treated water should be performed on a schedule recommended by local public
health authorities. At minimum test:
