Important Information
Operating Limits for all Actiblend Dual Draw System – Failure to adhere to these limits will result in liability for repairs
The Dual Draw System is designed for use with Actiblend Superconcentrate ONLY — Do not use any other products though the system.
Water Pressure - Operate Express units between 20psi and 70psi – higher line pressure will cause damage to internal parts & reduce dilution accuracy (40psi is optimal pressure).
Water Temperature – Operate Dual Draw unit in ambient temperatures not to exceed 100°F. Higher temperatures can damage internal parts.
Recommended Maintenance-In hard water areas Nuance recommends running a mild acid through the dispenser as needed to remove hard water build-up & scale deposits.
Never restrict flow at end of hose! If restricted, water will flow out the top of the vacuum breaker & hose could blow off spilling chemical on floor.
Troubleshooting Guide
Setup Problem |
Cause |
Possible solution |
Chemical not drawing |
Water pressure too low |
Connect to water source with at least 7gpm of flow at 25 psi |
|
Water pressure too High |
Connect to water source with at least 7gpm of flow below 70 psi or install pressure regulator |
|
Discharge hose connected at wrong end |
Reconnect discharge hose with priming ring 3-5 inches from dispenser |
|
Caps not connected properly |
Reconnect caps |
|
Air leak |
Tighten cap and put radiator clamps on both ends of chemical tubes |
Dilution to strong |
Metering tip too large |
Install smaller tip |
Dilution to Weak |
Metering tip too small |
Install larger tip |
Dual Draw system is sputtering/bubbles in the chemical tubes |
Air leak |
Tighten cap and put radiator clamps on both ends of chemical tubes |
Unequal draw of the A&B |
Slight variations in draw are to be expected but significant differences are due to incorrect tips |
Replace with correct tip or increase or decrease tip size accordingly |
