Troubleshooting Q&A

1

PROBLEM:
Sensor flashes continuously only when user steps within range

CAUSE:
A) Unit in start-up mode.

SOLUTION:
A) No problem. This feature is active for the first ten minutes of operation.

2

PROBLEM:
Valve doesn't flush; Sensor not picking up user

CAUSE:
A) Range too short.
B) Optima Plus installed on a high rough-in fixture (beam is shooting over user’s head.)

SOLUTION:
A) Increase the range.
B) Install EBV-46-A beam deflector. Note: Beam deflector shown is No Longer Available, entire electronic module must be replaced. See either #08712 (Closet) or #08709 (Urinal).

3

PROBLEM:
Valve doesn't flush; Sensor picking up opposite wall or surface, or only flushes when someone walks by. Red light flashes continuously for first ten minutes even with no one in front of the sensor

CAUSE:
A) Range too long.
B) Sensor is picking up mirror or highly reflective wall or surface in front of fixture.

SOLUTION:
A) Shorten range.
B) Install Optima Plus slightly off center (2° to 5°) to eliminate direct reflection off of mirror or opposite wall surface.

4

PROBLEM:
Valve DOES NOT flush even after adjustment

CAUSE:
A) Range adjustment potentiometer set at full "max" or full “min" setting.
B) Batteries completely used up.
C) Problem with electronic control module.

SOLUTION:
A) Readjust potentiometer away from full “max" or “min" setting.
B) Replace batteries.
C) Replace electronic control module. See either #08712 (Closet) or #08709 (Urinal).

5

PROBLEM:
Unit flashes four quick times when user steps within range

CAUSE:
A) Batteries low.

SOLUTION:
A) Replace batteries.

6

PROBLEM:
Valve DOES NOT shut off

CAUSE:
A) By-pass orifice in diaphragm is clogged with dirt or debris, or by-pass is clogged by an invisible gelatinous film due to "overtreated" water.
B) Dirt or debris fouling stem or inside parts assy.
C) Quad seal on stem or inside parts assembly damaged or worn.
D) Solenoid valve in electronic module has been overtightened.
E) Problem with electronic module.

SOLUTION:
A) Remove inside parts assembly and wash under running water. NOTE: size of orifice in by-pass is of utmost importance for the proper metering of water by the valve. Equiparts recommends that you do not enlarge or damage this orifice. Replace inside parts assembly if cleaning does not correct the problem.
B) Remove inside parts assembly and wash under running water.
C) Replace quad seal if necessary.
D) Turn solenoid counterclockwise very slightly.
E) Replace electronic module. See either #08712 (Closet) or #08709 (Urinal).

C) Control stop not adjusted properly.
D) Inadequate volume or pressure at supply.

CAUSE:
A) EBV-46-A beam deflector not installed.
B) Unusually short users not being detected.

SOLUTION:
A&B) Install EBV-46-A beam deflector to divert sensor beams. Note: Beam deflector shown is No Longer Available, entire electronic module must be replaced. See either #08712 (Closet) or #08709 (Urinal).

TO MAKE A RANGE ADJUSTMENT
Remove and then reinstall battery compartment door to activate 10 minute flashing range indicator feature. The range potentiometer is located at the top of the electronic sensor module beneath a rubber plug. Using the small screwdriver provided, turn the potentiometer a few degrees. Turn clockwise to increase range, turn counterclockwise to decrease range. Place cover over sensor module, position body into typical user range and check range by looking for red flashing light. Red light should only flash when picking up user. Repeat adjustment procedure until desired range is obtained. Reinstall optima plus. Refer to optima plus installation manual for greater detail on range adjustment procedures.

BATTERY REPLACEMENT
When Optima Plus has approximately 4000 flushes left, the same red light that appears at start-up will flash four times quickly whenever an object is detected. When this occurs, we recommend changing the batteries.

CARE AND CLEANING INSTRUCTIONS
DO NOT use abrasive or chemical cleaners to clean the Optima Plus, they may dull the luster and attack the Plastic Cover and the chrome finish of the flushometer. Use only soap and water, then wipe dry with clean cloth or towel. While cleaning the bathroom tile, the Optima Plus should be protected from any spattering of cleaner. Acids and cleaning fluids can discolor or remove chrome plating.
