STEALTH FLEX SYSTEM OVERVIEW
System Layout:
The Stealth Flex includes a carbon filter and a UV purification chamber. It must be installed with the
carbon filter at the water inlet, and the UV at the outlet. See page 4. The Stealth Flex should be
installed on the cold water line between the water source, such as the pump or pressure tank. or
water line; and the point of use faucet. Ideally the Stealth should be the last component the water
passes through before the faucet.
It is optional to provide a dedicated stand alone drinking water faucet for the Stealth Flex system.
Operator preference should dictate this decision. Considerations include a slight pressure drop asso-
ciated with the carbon filter, and if a fully isolated water purifier is required.
Mounting:
The Stealth Flex can be mounted to configure the inlet on the Right or Le side of the system. Note
that the Mounting Bracket (5) must be arranged to provide the inlet to the Carbon Filter on the
desired side. See instructions on Page 6 for reversing the Mounting Bracket if necessary.
Electrical Supply
The Stealth requires 12v power supply, drawing 1 amps when activated. Alternately a 12V power
adapter can be used to connect to 110V.
Operation:
The Stealth Flex has a instantaneous flow sensing switch which detects water flow and immediately
activates the UV. The Stealth Flex will sense that water is moving when you open the faucet. The
sensor will notice a minimum of 0.3 litres per minute flow rate. LED technology allows it to instantly
switch ON the UV chamber to full power and effectiveness with no warm up necessary. It draws mini-
mal power when it is in standby mode.

STEALTH FLEX INSTALLATION
Tools required:
No 2 Philips Head Screwdriver
Tube Cutter (Optional)
General Practices
• Read all instructions before use.
• Remove the Stealth Flex from Packaging, ensure contents are complete.
• Do not power on UV without water connected and initial flushing.
•For installation location, consider ease of access for filter changes, minimum bend radii of tubing,
and access to electrical connections.
• Do a quick test fit before beginning installation.
• Use appropriate connection fittings compatible with the inlet and outlet fittings.
Instructions
1) Turn off water supply, and/or all pumps supplying pressure to the water system.
2) Determine plumbing layout. Stealth may be mounted with inlet on the right or le hand side of
the unit. See Page 4. Plan for adequate space for inlet and outlet plumbing to have a clean approach,
and to be secured to minimize movement and vibration when installation is complete. PEX tube (1)
may be trimmed using Tube Cutter, or may bend to fit irregular spaces and installations.
3) Install Filter Mounting Bracket (4) to top of filter housing for Right or Le inlet. Note IN and OUT
sides of filter. IN should come from water supply, and OUT should connect to PEX tube (1) and on to
UV Unit (17). See Page 4 and 6.
4) Unscrew Filter Housing Canister, Clear (9) and set aside with Filter (16).
(5) Holding Filter Mounting Bracket (4) in place, attach to wall with provided Wood Screws (3) using
No 2 Philips Head Screwdriver. Screws are self tapping. Do not over-tighten screws, substrate mate-
rial may strip if over-tightend. If mounting in a material other than wood, metal, or plastic, substitute
appropriate fasteners. Filter should be oriented so that Filter Cannister (9) is down so that the filter
may be changed without spilling water.
6) Push PEX Tube (1) into Filter OUT connection. See instructions Page 11 for using Push To Connect
Fittings. Once connected, pull o the tube to tension the Push To Connect fitting to create seal.

7) Push other end of PEX Tube (1) into Flow Sensor side of UV unit. Remove Blue Clip on Flow Sensor
fitting if necessary. Replace blue clip to secure collar.
8) Select 3/8” (13) or 1/2” (12) Barbed Adapter to fit local plumbing. Supplied Barbed fittings will
work with Braided PVC tube, as well as some PEX tubing. For other fittings, see Tips or consult
www.guzzleh2o.com. Push barbed fittings into local plumbing, and secure with worm drive hose
clamp.
9) Insert stem of Barbed fittings (12 or 13) into INLET of Carbon Filter, and OUTLET of UV unit (17). See
Push To Connect Fitting Instructions Page 11.
10) Connect power cable cable (5) to 12V power supply. RED cable connects to positive (+) terminal
. BLACK cable connects to negative (-) terminal. Connect barrel plug to underside of UV unit. Trim
power cable length as necessary. See Wiring Diagram Page 10.
11) Use Cable Ties (14) to secure UV Purification Chamber (17) and PEX tube (1) as necessary to mini-
mize movement. Note correct orientation of UV Purification Chamber (Page 13).
12) Install Carbon Block Cartridge (16) and Filter Housing Canister, Clear (3) making sure O-ring (10)
seats in groove in canister. Tighten firmly by hand.
13) Turn on water supply. Determine that there are NO LEAKS.
14) Turn on power to UV and test operation. GREEN light indicates power is ON. BLUE light indicates
UV system is ACTIVE when water flows. BLUE light should turn off when water flow stops. See Status
Light Codes Page 15.
15) Flush carbon fines out of new Carbon Filter. Run 3-5 gallons of water through Stealth Flex to
remove carbon fines from new Carbon Filter. You will see black sediment in water as fines are
removed.
16) Have a drink of clean water!

STEALTH FLEX OPERATION
When power is connected to the Stealth, the green indicator LED illuminates to indicate it is
on STANDBY MODE (see page 9). In this mode, the Stealth is ready to purify water, but has
not yet activated the UV purification chamber.
The UV purification function of the Stealth activates automatically by sensing water flow and
activating the UV purification chamber when water is moving. A few seconds aer the water
stops, the Stealth turns the purification chamber off. Water flow typically is started and
stopped by using your faucet. UV purification activity is indicated by the BLUE LED indicator
light. The sensor requires a minimum of 0.3 liters per minute of flow to activate.
LED technology allows the UV purification chamber to instantly activate and perform at full
effectiveness. The UV chamber does not require any time to “warm up.”
The Stealth can be le on STANDBY MODE indefinitely. The UV function should only
activate when water is running.
Pulsecare:
When the UV unit is in Standby Mode, and water is not flowing, the UV unit will periodically
activate to clean the UV chamber. This prevents microbiological pathogens from migrating
through the chamber due to natural colonization and transport. While inactive, the UV will
flash for 1 second every 30 minutes.
If system is le off for more than 12 hours, contamination from microbiological migration is
possible, and water lines should be sanitized.

STEALTH FLEX MAINTENANCE - CHANGING CARBON FILTER
WHEN TO CHANGING THE CARBON BLOCK FILTER
Carbon block filters should be changed aer 1000 gallons of use. Actual capacity may vary depending
upon quality of water filtered. Reduced water flow rate through filter or at the faucet is an indication that the
carbon block filter element should be changed.
HOW TO CHANGE CARBON BLOCK FILTER
Shut off water pressure, and open faucet to drain and depressurize water line. Place a towel below filter
canister to catch any water that may drain. Unscrew carbon block filter canister (9). Use a filter wrench if
necessary. Locate the o-ring (10) on the perimeter of the canister. Drain water and remove carbon block
element (4) . Place new carbon block filter element in the cannister. Make sure canister o-ring (10) is prop-
erly seated and cartridge gaskets are in place. Thread the cannister onto filter housing base. Make sure top
and bottom of filter cartridge is centered on mounting See below for list of acceptable replacement filters.
Tighten cannister firmly by hand, making sure o-ring seals. Turn on water pressure, let water run. Run 5
gallons of water through system to dislodge and remove any loose carbon fines. Close faucet and check
for leaks.

FREEZING TEMPERATURES CAN DAMAGE STEALTH AND CAUSE WATER SYSTEM LEAKS AND
DAMAGE
Temperatures below 32F (0C) can damage the Stealth Flex causing leaks and loss of peformance.
Follow WINTERIZATION PROCEDURES to prepare Stealth for freezing conditions.
WINTERIZATION PROCEDURES
In below freezing temperatures, water MUST BE REMOVED from the Stealth Flex or damage may occur to the
UV unit and carbon filter. Follow these guidelines in addtion to any recommendations that may come with the
rest of your water system.
1) Unscrew FILTER CANISTER (7) and drain water. Remove CARBON BLOCK CARTRIDGE(16).
2) Open faucet. Use an air compressor to inject air into the outlet hole in the center of the filter housing base
nearest the UV unit.. Pulse air into the outlet hole as shown on page 12 to push air and water out through the
UV unit. Water should come out of open faucet. Pulse air until no more water is expelled through faucet, and
water is removed from UV unit.
3) Reinstall the CANISTER (7) without the CARBON BLOCK CARTRIDGE (16). Allow CARBON BLOCK FILTER
(16) to dry, and store for re-installation, or replace if expired.
ALTERNATIVELY TO THIS PROCEDURE, anti-freeze fluid may be used to protect the Stealth Flex from freezing
conditions. Remove CARBON BLOCK CARTRIDGE (16) and follow manufacturer instructions for distributing
food safe anti-freeze fluid throughout the system including the Stealth to prevent water from freezing.

STEALTH SYSTEM TIPS AND TROUBLE SHOOTING
1) Secure all hoses and cables connecting to the Stealth Flex. Loose and vibrating connections can lead to
water leaks and faulty electrical connections.
2) Aer replacing carbon filter cartridge with a new filter, some visible black carbon fines may be dislodged
in new carbon filter. This is normal, allow approximately 5 gallons of water to pass to remove carbon fines.
3) For best performance, filter and purify water as close to point of use as possible. The Stealth should be
the last thing your drinking water passes through before faucet. For whole system filtration, consult Guzzle
H2O.
4) For installation, consider ease of access, max length and minimum bend radius of piping, electrical
connnections when selecting installation location. Use appropriate pipe and tubing compatible with
supplied barbed fittings.
5) The carbon filter will cause a 3-5 psi pressure drop in line pressure as it filters water. This may cause auto-
matic pressure water pumps to cycle on and off as pressure limit is reached. This is normal. Adjust pump
pressure to accommodate, or consult Guzzle H2O for higher flow options.
6) Stealth Flex should be installed in a protected, watertight area. It is very rugged, but not made for
outdoor installation.
7) There are various inlet and outlet attachments that accomodate PEX tubing, and faucet connections.
Consult Guzzle H2O for options for specific plumbing connecitons.
8 Periodically clean onboard water tanks by shock treating with bleach or chlorine. This will reduce build-
up of contaminants. The carbon block filters will do an excellent job of removing any residual chlorine from
cleaning efforts.
9) Lubricate filter canister threads with food safe silicone grease to make threading cannister easier.
10) A 110V power adapter is available for installations requiring connection to mains power.
11) Use double sided tape to hold mounting bracket to wall to secure mounting screws.
12) Replacement filters are available on a subscription basis from www.guzzleh2o.com for automatic re-or-
der every 6 months.
