How to use
Shut off the water supply before beginning installation. Remove the old hose from the faucet outlet and supply valve, then clean the connection surfaces. Hand-thread the M10 end onto the faucet outlet until seated, taking care not to cross-thread; tighten to the manufacturer's recommended torque or finger-tight plus a quarter turn with an appropriate wrench if required.
