Installation

Installation Supply List:

• (1) Dual Draw Dispenser
• (1) 6’ braided discharge hose with clamp
• (2) clear chemical connector hoses
• (2) chemical connector caps
• (2) dilution tip kits with chart
• (1) bag of fasteners

 

NuBlend Dual Draw Installation Requirements:

 

• Mount the Dual Draw dispenser above the chemical components to prevent siphoning of the chemical. The location should be an area with enough room to bring all cleaning equipment close to the NuBlend Dual Draw System.
• The area should have a floor drain to ease dumping of dirty cleaning solution before filling cleaning equipment.
• The dedicated water line with a garden hose connection must have a minimum of 7gpm of flow.

 

Step 1 – Mount unit to wall using hardware provided. Make sure unit is mounted above where containers will be placed.

 

 

Step 2 – While facing the unit, select and insert dilution tip into eductor on the left for component A, then connect chemical hose to eductor. Next, select and insert dilution tip into eductor on the right for component B, then connect the chemical hose to eductor.

 

 

Step 3 – Connect discharge hose to dispenser using plastic clamp. IMPORTANT: make sure priming ring is 1 to 2 inches below dispenser in the hose.

 

 

Step 4 – Connect chemical hoses to connector caps. Trim excess hose if needed. Use radiator clamps to prevent air leaks.

 

 

Step 5 – Place pails of A&B components below dispenser and connect cap to pails tightly. Be sure to connect the proper cap to the correct component.

 

 

Step 6 – Connect incoming water line to garden hose fitting on dispenser.

 

 

Step 7 –  Mount the hose hook to the left, below the dispenser, as you face the system.

 

 

Step 8 – Turn on water supply, then turn operating ball valve to the ON position. Chemical should draw up both tubes and dispense RTU cleaner.

 

 

Step 9 – For drum installations, follow the same procedures, making sure the dispenser is above the top of the drums.

 

 

Important Information

• Always follow the Operating Limits for all NuBlend Dual Draw Systems. Failure to adhere to these limits will result in liability for repairs.
• The Dual Draw System is designed for use with NuBlend Superconcentrate ONLY. Do not use any other products in the system.
• Water Pressure – Operate Express units between 20psi and 70psi. Higher line pressure will cause damage to internal parts and 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 buildup and scale deposits.
• Never restrict flow at end of hose! If restricted, water will flow out of the top of the vacuum breaker and the hose could blow off, spilling chemical on the floor.
