• The HW6 is shipped intergrated within a 4 11/16″ X 4 11/16″ X 2 1/8″ electrical box.
• It is advisable to install the HW6 power supply in an accessible location, as close as possible to the flush valves it will power. Ideal location is behind an access panel, in a pipe chase, or above a drop ceiling. The greatest distance to any valve shall ideally be less than 20 ft., (40 ft. max.).
• The Zurn-HW6 Power Converter shall be direct wired with continuous 120VAC, 60Hz from the building supply.
• The HW6 can be used to power up to 8 ZEMS-IS flush valves.
• Enclosed with each valve is 1 (one) connecting wire to power ZEMS-IS actuator.
• The wire shall be wire nut connected to the low voltage red (+) and blue (-) leads from the power supply as shown in (Figure 1).
• The connecting wire is polarized. The black lead with white trace is (+) and connects to the red wire from the power supply. The plain black lead is (-) and connects to the blue lead on the power supply. Do not cross wires as it will cause damage to the product!
• Connecting wire shall be run from the power supply to the predrilled 1-1/2″ diameter holes in the finished wall for final connection to the flush valves. (Figure 2)

IMPORTANT

1. Must use a Zurn power supply to ensure proper voltage for the system. Correct polarity is necessary to prevent damage to the sensors. Check DC power level to ensure the power supply is providing a minimum of 7.4 volts DC. DC levels less than 7.4 volts will result in malfunction of the units.
2. Be certain to use the lengths of wire provided with each power supply when wiring the bathroom for the flush valves. The connector and wire gauge have been selected specifically to match the Zurn Flushometer valve.
3. Each Flush Valve should be wired in parallel as shown in the wiring diagram below.
4. Ensure the access hole behind the flush valve is a minimum of 1-1/2” in diameter and located per Zurn templates #FV329 and #FV330. The plug end of the low voltage wire needs to be accessible at this hole when the plumber installs the flushometer valve.

Note : Connect to either the HW6 or PC6 power converter

CALIBRATION INSTRUCTIONS FOR ZEMS-IS III

1. Obtain a target. SEE FIGURE 11.
2. PRESS and HOLD button for 10 seconds until the LED turns solid. (Unit will blink four times and flush once while button is being held)
3. RELEASE finger after LED turns solid.
4. PRESS and HOLD button when LED starts blinking.
5. RELEASE finger when LED turns solid.
6. Set target at desired distance, (No less than 16″) from sensor face and verify NO other objects are in view of sensor face.
7. Keep target steady – Unit will blink while calibrating.
8. After 15 seconds, calibration ends with a fast double blink or a solid LED for 5 seconds.
9. IF THE LED REMAINS SOLID FOR 5 SECONDS AFTER CALIBRATION, the calibration was NOT successful. REPEAT STEPS 2-8
10. For closet installations continue to “VERIFY CALIBRATION FOR CLOSET INSTALLATIONS”.

VERIFY CALIBRATION FOR CLOSET INSTALLATIONS

1. Stand outside closet stall and close door.
2. Slowly open door to closet stall while looking at ZEMS-IS sensor.
3. If led blinks while door is opening, recalibrate to a shorter range. FAILURE TO DO SO WILL RESULT IN GHOST FLUSHING.

STEP 12 – Activating the Motor Actuator with the Sensor
To activate the motor actuator with the sensor, simply place a target in front of the sensor. A single red light will flash indicating the sensor has recognized the target. If the target stays in view for eleven seconds, two flashing red lights will occur. This indicates that the target has been in view for the required time and upon leaving the view, a signal will be sent to the motor actuator to flush the flush valve. NOTE: If the target does not stay in view for the required eleven seconds, a flush will not occur

TROUBLE SHOOTING

open enough.

2.) Urinal trip mechanism installed in closet kit. Urinal kit installed in closet valve, or 1.0 gal. urinal kit installed in place of 1.5 gal urinal kit.

3.) Insufficient volume or pressure at supply.

| 1.) Open stop valve for desired volume of water.

2.) Install appropriate parts or kit.

3.) If gauges are not available to measure supply pressure or volume of water at the valve, completely remove the working parts and open the stop valve to allow water to pass through the empty valve. If the water supply proves unsatisfactory, steps should be taken to increase the pressure and/or supply.

Flush valve does not activate after user leaves.| 1.) Sensor does not recognize a user. 2.) Power supply may be disrupted.| 1.) Re-calibrate sensor per step 10.

2.) Check available voltage where escutcheon is attached to wall with DC voltmeter. 7.4-9 VDC is required.

Flush valve shuts off too quick.| 1.) Damaged or punctured diaphragm. 2.) Enlarged by-pass orifice.

3.) Cylinder guide assembly and diaphragm assembly are

not tight.

4. ) Enlarged by-pass orifice.

5.) Urinal trip mechanism (black) in closet flush valves.

| 1.) Install new replacement kit to remedy the prob-

lem.

2.) Install new replacement kit to remedy the prob- lem.

3.) Screw the two assemblies hand tight.

4.) Install new Z6000-ECA, Z6000-EUA replace- ment kit to remedy the problem.

5.) Install closet trip mechanism (white).

Valve activates repeatedly when

power is provided.

| 1.) Insufficient DC power level (less then 7.4 volts DC)| 1.) Upgrade the -HW6 power supply to the new ZURN power supply (greater than 7.4 volts DC) or replace the PC6 supply.
Valve is flushing too long or not shutting off.| 1.) Trip mechanism not seating properly due to foreign material between trip mechanism and retainer disc.

2.) By-pass orifice is plugged or partially plugged.

3.) Line pressure is not adequate to force trip mechanism to seal.

4.) Cracked cover.

| 1.) Disassemble parts and rinse thoroughly.

2.) Examine by-pass orifice and clean if necessary being certain not to enlarge orifice opening.

3.) Pressure is inadequate or has dropped below min- imum operating range. Steps should be taken to increase the line pressure.

4.) Replace cover with new one.

Water splashes out of fixture.| 1.) Supply volume is more than is necessary.

2.) Lime accumulation on vortex or spreader holes of fixture.

| 1.) Adjust downward on control stop.

2.) Remove the lime build up within the fixture.

Flush is not considered quiet.| 1.) Control stop may not be adjusted for quiet operation 2.) Fixture may be contributing to noise

3.) Piping system may be source of noise.

| 1.) Adjust the control stop for quiet operation keeping

in mind the fixture evacuation requirements.

2.) Check noise created by fixture by placing a cover over the bowl opening to separate valve noise from bowl noise. If it is determined the fixture is too noisy consult with fixture manufacturer.

3.) High pressure in the system can sometimes be controlled by the stop valve. Other sources of noise may be the absence of air chambers and shock arres- tor, loose pipes, improper size pipes, etc. In these

cases the building engineer should be consulted.

Flush valve “ghost” flushes or activates randomly with no user present.| 1.) Lens may be dirty.

2.) Power supply output is out of tolerance. 3.) Sensor is viewing stall door.

| 1.) Clean lens.

2.) DC voltage must be between 7.4-9 volts. Check for power fault or malfunction in a unit or replace with a Zurn power converter.

3.) Re-calibrate sensor per step 10.

Sensor assembly leaking| 1.) Sensor assembly is not tight.| 1.) Tighten sensor assembly.

Care of Chrome plated surfaces.

• The suggested cleaning of chrome plated surfaces is simply to clean them with soap and water then dry. Commercial cleaning compounds are never recommended. Seasonal use.
• Valves used in installations subject to shut down because of cold and freezing conditions should be maintained in the following manner. After the main supply has been shut off and the water drained from the system, remove the stop valve cap and stop internals to allow the water to drain from the flush valve itself.
