4. Setup and Installation
The CR Mod Plus 1 cistern is designed for low-level or medium-level installations. Follow these steps for proper setup:
- Prepare the Installation Area: Ensure the wall surface is clean, dry, and capable of supporting the cistern's weight when full. Turn off the main water supply to the toilet.
- Positioning: Determine the desired height for the cistern (low-level or medium-level). Use the provided mounting template to mark the drilling points on the wall.
- Drill Holes: Drill holes at the marked positions using an appropriate drill bit for your wall type. Insert the wall plugs.
- Mount the Cistern: Secure the cistern to the wall using the provided wall fixing kit. Ensure it is level and firmly attached.
- Connect Water Supply: The cistern features a water inlet for right or left connection. Connect the 3/8'' water supply line to the float valve. Ensure all connections are tight to prevent leaks.
- Connect to WC: Attach the 50x40 mm drain pipe from the cistern to the toilet bowl inlet. Use the provided connection gaskets to ensure a watertight seal.
- Check for Leaks: Slowly turn on the main water supply and allow the cistern to fill. Inspect all connections for any signs of leakage. Tighten connections as necessary.

5. Operating Instructions
The CR Mod Plus 1 cistern features a single start/stop flush button for water saving.
- To Flush: Press the flush button located on the top of the cistern.
- To Stop Flush (Water Saving): Press the flush button a second time while water is still flowing to stop the flush prematurely, saving water.
- Capacity Adjustment: The 9-liter capacity can be adjusted internally by modifying the float mechanism. Refer to the internal mechanism diagram (not provided in this manual) for specific adjustment points if needed. This adjustment should only be performed by a qualified person.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your cistern.
- Cleaning: Clean the exterior of the cistern with a soft cloth and mild, non-abrasive detergent. Do not use harsh chemicals, abrasive pads, or solvents, as these can damage the ABS shell.
- Internal Components: Periodically check the float valve and flush mechanism for any debris or mineral buildup. If necessary, turn off the water supply, drain the cistern, and clean the components.
- Gaskets: Inspect connection gaskets for wear or damage. Replace them if leaks occur or if they show signs of deterioration.
