The following text shows the answers to the top four frequently asked questions (FAQs) asked by installers of the “Splash Shower System Company”. Use this text to answer the four questions that follow it:
FAQ 1
The “Splash” Divine range of ‘All in One’ power showers are products which have the pump and mixing valve in one box. They only require a minimum distance of 75mm from the base of the cold-water cistern to the top of the “Splash” Divine case. This is to ensure there is enough ‘gravity fed water’, to prime the internal pump. This vertical distance will need to be increased in direct proportion to how far the product is away from the stored cold-water supply.
FAQ 2
The “Splash” Therm One shower is the first thermostatic electric shower, (controlling to +/- 1 degree centigrade) available. It incorporates push button control for flow and on/off control plus a version with extended lever temperature control for easier grip. A maximum temperature setting can currently be set to ensure the outlet temperature does not exceed 43 degrees centigrade.
FAQ 3
When the “Splash” Therm One 10.8kW shower is installed on a 240v supply it requires a 45 Amp supply fuse. To minimise voltage drop, and thereby maximise shower performance the minimum cable size required must not less than 6mm. All “Splash” electric showers will accommodate up to 10mm cable and the “Splash” Therm Two, up to 16mm. Use the shortest possible cable route from the consumer unit to the appliance.
FAQ 4
Do not connect a “Splash” Dream 3 to a mains water supply, as product damage will occur, and Water Regulations will be contravened. The “Splash” Dream 3 is designed to be gravity fed from a cold-water storage cistern. The “Splash” Dream 3 is not a power shower and a higher flor rate will not be achieved in installed on mains pressure. A ‘power shower’ is one where stored hot and cold water is pumped via a mixing valve.
