Cleaning Sensors
IMPORTANT: Sensors must be cleaned by hand before being
inserted into their respective chamber!
1. How to clean pH sensor:
- Remove sensor from assembly and cable
- Wipe off any pollution with paper tissue, rinse with water
- NEVER use abrasive substances on glass bulb!
- Use mild acid (dilute HCl) to remove stains, use alcohol to
remove fats
- Rinse with water and reinstall
2. How to clean DIS sensor:
- Remove sensor from assembly and cable
- Wipe off any pollution with paper tissue, rinse with water
- Clean metal bands with powder detergent (ex. Comet), wipe
gently
- Rinse with water and reinstall
Calibrating Sensors
pH Sensor
1. Menu > Cal > Cal pH
2. Calibrate sensor with pH 7 buffer solution followed by pH
4 buffer solution
3. Save results
DIS Sensor
1. IMPORTANT: Clean sensor before proceeding with
calibration!
2. Using water sample taken from Sampling Reference
Valve, perform DPD test
3. Menu > Cal > Cal DIS > enter DPD reference value > Ok
> Save
Inserting Sensors
1. Insert pH sensor into the Flow Cell Chamber for the pH
Sensor (7) and screw on the pH cable
2. Insert Disinfection sensor into the Flow Cell Chamber for
the Disinfection Sensor (9) and screw on the Disinfection
Cable
Check Your Flow
Make sure the Water Sampling Reference Valve is in the closed
position.
System needs proper flow to operate. “Digital input 1 – no
water” will show on display screen if flow is not strong enough.
Flow minimum: 5 psi Flow maximum: 87 psi
General Steps
1. Mount the system upright on the wall
2. Insert clean sensors
3. Power on system
4. Check flow
5. Calibrate sensors
6. If needed, set user specific settings –
see operations manual
a. ASR
b. 4 –20 mA
c. Relay Alarms
IMPORTANT: Secure lock pin after opening and
closing your system to protect from water
damage!
