STEALTH SYSTEM OVERVIEW

System Layout:
The Stealth includes a carbon filter and a UV purification chamber. Water must pass through the carbon filter as the first stage, and the UV chamber as the second stage. See page 4. The Stealth should be installed on the cold water line between the water source, such as the pump, 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 system. Operator preference should dictate this decision. Considerations include a slight pressure drop associated with the carbon filter, and if a fully isolated water purifier is required.
The INLET and OUTLET elbows may be rotated 360 degrees to accommodate plumbing layouts.
Mounting:
The Stealth should be mounted on a vertical wall. The system should be oriented with the clear filter cannister down so water does not spill when the housing is unscrewed. Select a location where plumbing can route cleanly, and access for filter changes is good.
Electrical Supply
The Stealth requires 12v power supply, drawing 1 amp when activated. Alternately a 12V power adapter can be used to connect to 110V.
Operation:
The Stealth has an instantaneous flow sensing switch which detects water flow and immediately activates the UV. The Stealth will sense that water is moving when you open the faucet. The sensor will notice a minimum of 0.3 liters 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 minimal power when it is in standby mode.

STEALTH INSTALLATION

Tools required:
No 2 Philips Head Screwdriver
Flat Head Screwdriver
General Practices

• Read all instructions before use.
• Remove the Stealth 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. Please check www.guzzleh2o.com for accessory fittings for specific push to connect fittings that may aid your particular installation.

Instructions

1. Turn off water supply, and/or all pumps supplying pressure to the water system.
2. Determine plumbing layout. Note the inlet and outlet connections. Note that inlet and outlet elbows may swivel 360 degrees to accommodate plumbing layouts. 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.
3. Unscrew Filter Housing Canister, Clear (10) and set aside with Filter (12).
4. Using Bracket Mounting Hole Pattern on Page 8, mark fastener locations for upper 2 screws on mounting surface. Thread 2 Screws (4) into mounting surface using No 2 Philips Head Screwdriver.  Stop turning screws to leave a small gap under screw head. Screws are self tapping. Do not over-tighten screws, substrate material may strip if overtightend. If mounting in a material other than wood, metal, or plastic, substitute appropriate fasteners.
5. Hang bracket by top screws. See Page 9.
6. Install 2 screws into mounting surface through 2 holes on lower side of mounting bracket. Then snug up the upper screws on the bracket. See page 9.
7. Select 3/8” (7) or 1/2” (6) Barbed Adapter to fit local plumbing. Supplied Barbed fittings will work with Braided PVC tube, as well as some PEX tubing. For other fittings consult www.guzzleh2o.com.  Push barbed fittings into the tube delivering water to the Stealth, and the outlet tube. Use a flat head screwdriver to secure with worm drive hose clamp (8)
8. Insert stem of Barbed fittings (7 or 6) into INLET of Carbon Filter, and OUTLET of UV unit (17). See Push To Connect Fitting Instructions Page 12.
9. 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 11.
10. Secure inlet and outlet plumbing, and power cable as necessary to minimize movement and vibration.  Avoid excessive loading on inlet and outlet plumbing.
11. Install Carbon Block Cartridge (12) and Filter Housing Canister, Clear (10) making sure O-ring (11) seats in groove in canister. Tighten firmly by hand.
12. Turn on water supply. Determine that there are NO LEAKS.
13. 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.
14. Flush carbon fines out of new Carbon Filter. Run 3-5 gallons of water through Stealth to remove carbon fines from new Carbon Filter. You will see black sediment in water as fines are removed.
15. Have a drink of clean water!

STEALTH 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 aer 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.
UV 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 MAINTENANCE – CHANGING CARBON FILTER

WHEN TO CHANGE THE CARBON BLOCK FILTER
Carbon block filters should be changed aer 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 (10). Use a filter wrench if necessary. Locate the o-ring (11) on the perimeter of the canister. Drain water and remove carbon block element (12) . Place new carbon block filter element in the cannister. Make sure canister o-ring (11) is properly 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.

STEALTH MAINTENANCE – WINTERIZING

WARNING
FREEZING TEMPERATURES CAN DAMAGE STEALTH AND CAUSE WATER SYSTEM LEAKS AND DAMAGE
Temperatures below 32F (0C) can damage the Stealth causing leaks and loss of performance.
Follow WINTERIZATION PROCEDURES to prepare Stealth for freezing conditions.
WINTERIZATION PROCEDURES
In below freezing temperatures, water MUST BE REMOVED from the Stealth or damage may occur to the UV unit and carbon filter. Follow these guidelines in addition to any recommendations that may come with the rest of your water system.

1. Unscrew FILTER CANISTER (10) and drain water. Remove CARBON BLOCK CARTRIDGE(12).
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 18 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 (10) without the CARBON BLOCK CARTRIDGE (12). Allow CARBON BLOCK FILTER (12) 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 from freezing conditions. Remove CARBON BLOCK CARTRIDGE (12) and follow manufacturer instructions for distributing food safe anti-freeze fluid throughout the system including the Stealth to prevent water from freezing.

WINTERIZATION PROCEDURES

STEALTH SYSTEM PRO TIPS

1. Secure all hoses and cables connecting to the Stealth. Loose and vibrating connections can lead to water leaks and faulty electrical connections.
2. Aer 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  connections 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 automatic 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 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 accommodate PEX tubing, and faucet connections.  Consult Guzzle H2O for options for specific plumbing connections. See www.guzzleh2o.com for a selection.
8. Periodically clean onboard water tanks by shock treating with bleach or chlorine. This will reduce buildup 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. See www.guzzleh2o.com.
11. Replacement filters are available on a subscription basis from www.guzzleh2o.com for automatic re-order every 6 months.
