The spigot can be supplied in advance of the tap body if a phased installation is required. Connections are by 10mm compression fittings for copper pipe (or Soft-PEX flexible braided hose as an accessory). Extension/spacer pieces are available to accommodate for a range of basin sizes. Offer the extension piece up to the spigot ensuring the correct alignment of the interconnect nozzles. Secure the extension piece to the spigot with the 4 M5 screws and washers. Offer the tap body up to the extended spigot and mount it firmly then tighten the tap's retaining screw from below. Fit the tap's bottom cover and tighten using a strap wrench. Open the hot and cold water supplies. The correct commissioning procedure (Flushing, setting the temperature, CW failure test) must be followed prior to usage.
