RV SUPREME MK2 Diaphragm Pump Manual - Technical and Customer Service Version

Introduction:

The RV SUPREME MK2 diaphragm pump builds on the strengths of its predecessors, offering robust power and pressure capabilities. It is designed to be versatile, suitable for applications requiring less flow, and is ideal for installation in confined spaces. The pump can be customized with various inlet types to suit different applications.

Specifications and Features:

• Dry Running Capability:

  The pump can operate dry without damage under normal conditions.

• Self-Priming:

  Facilitates easy startup and operation.

• Strainer Attachment:

  Must be attached to the inlet side to protect the pump from debris.

• Encapsulated Check Valve:

  Ensures minimal backflow with a cracking pressure not exceeding 2 psi.

• Factory Fitted Check Valve:

  Reduces the risk of air bubbles and enhances performance.

• Bypass Valve:

  Pre-set for optimal operation; adjustable to suit specific application needs.

Installation Guidelines:

1. Inlet and Outlet Fittings:

   Use provided plastic fittings instead of metal to avoid corrosion. Ensure all fittings are securely attached without overtightening to prevent damage.

2. Electrical Connection:

   The pump should be connected to a dedicated circuit. Connect the positive lead (red) to the positive terminal of your battery and the negative lead (black) to the negative terminal.

3. Mounting:

   Install the pump in a dry, easily accessible location away from direct exposure to weather elements.

4. Over-Current Protection:

   Protect the circuit with a fuse to prevent electrical overload.

5. Wire Sizing:

   Refer to the wire chart for correct gauge selection based on installation specifics.

Operating Instructions:

Turn the pump on and off at the main control to manage operation. Ensure the pump is off when not in use to prevent wear and extend its lifespan.

Troubleshooting:

• Pump Cycles On and Off:

  Check for leaks in the system, ensure the mounting is secure, and verify that the check valve is not obstructed.

• No Pump Discharge Despite Running Motor:

  Inspect for clogged pipes or a defective check valve.

• Motor Fails to Turn On:

  Check electrical connections, ensure proper fuse function, and verify motor integrity.

• Pump Fails to Turn Off:

  Confirm that all fixtures are properly closed and check for leaks or blockages in the discharge line.

• Low Flow and Pressure:

  Inspect for worn or damaged parts, and ensure the system is free from leaks and blockages.

Maintenance:

Regularly check and clean the strainer.
Verify the operational status of the check valve and replace if necessary.
Periodically test the pump's voltage to ensure optimal performance; voltage should be consistent during operation.
Winterize and maintain the pump especially before and after prolonged storage to prevent damage and ensure reliability.

About the Bypass:

The bypass valve is critical for managing the pump's operational pressure. If adjustment is needed beyond the preset settings, carefully tighten or loosen the screw to change the pressure settings. Always consult a professional technician if unsure about these adjustments.

Caution:

Follow all installation and operation instructions as per this manual. Deviations may result in damage not covered by warranty.
Ensure all electrical installations comply with industry standards and local regulations.
