Ultra ZSPSBARCA14 is a thermostatic cartridge for selected Ultra, Hudson Reed, Premier Bathrooms and Nuie shower panels. The supplied cartridge is an updated version and may differ slightly in appearance from the original.
The cartridge controls the mix of hot and cold water to maintain the selected shower temperature. A worn or faulty cartridge can cause erratic temperature control or difficulty adjusting the water temperature. Check the water supplies and the condition of the valve before deciding which part needs attention.

Fitting Notes
Follow the servicing instructions for your exact panel and isolate the hot and cold water supplies before starting. On AS374 panels, the thermostat's side retaining screw must be released before the cartridge is withdrawn. Lightly lubricate suitable O-rings with silicone grease when fitting.
