How to use

Install the SIAMP OPTIMA 49 according to the cistern manufacturer’s guidance or the valve’s fitting instructions, ensuring the water supply is turned off before removal of the old valve. Position the valve in the cistern outlet and secure the mounting to achieve a watertight seal. Adjust the actuator or linkage as needed so that the small and large flush options operate correctly with the cistern’s push-button or lever. After installation, turn on the water supply and test both flush volumes to confirm proper sealing and operation; perform any minor adjustments to the actuator heights or seals to eliminate leaks.

Usage recommendations

For reliable long-term performance, periodically check seals and moving parts for wear, and clean mineral deposits if present. Use the small flush for liquid waste and the large flush for solid waste to optimize water savings. When replacing an existing valve, compare mounting dimensions and actuator type to ensure compatibility. If uncertain about installation, consult a qualified plumber or follow manufacturer instructions provided with the product.
