Can I use push-fit pipe and fittings to install my Triton electric shower?
Yes, you can use push-fit plumbing except for the final connection onto the shower inlet, which must be a 15mm compression fitting to ensure a watertight connection.
Do I have to fit a double – pole isolation switch when I install my Triton electric shower?
Yes, for the purpose of future servicing of the shower a ceiling or wall mounted DP isolation switch is required. It is also good practice to isolate the shower when not in use.
Is it possible to connect an electric shower to an electric circuit that is feeding another appliance?
An electric shower must have its own dedicated power supply. The only exception to this rule is when installing a Triton body dryer. The Body dryer can be connected to the same electric supply cable that is feeding the shower. A switch in the Body dryer prevents the shower from operating at the same time as the Body dryer, therefore ensuring the circuit is not overloaded.
What size electric cable is required for an electric shower?
The size of cable that can be used for an electric shower depends on a number of factors which includes, the kilowatt rating of the shower, the method of cable installation, any de-rating factors and the length of circuit. In some cases 6mm² cable will be adequate for a shower rated up to 8kW. For showers above 8kW it may be necessary to install 10mm² cable.
In order to comply with Part P building regulations a competent installer familiar with the requirements of the current I.E.E regulations must assess the proposed circuit in order to select the correct cable size.
What type of plumbing fitting is required to connect onto the inlet of Triton electric showers?
The range of mains fed electric showers and the T90xr pumped electric shower require a 15mm compression fitting to be used.
The T80si pumped shower has a 15mm push – fit inlet connection.
What will happen if the incorrect fuse size is fitted for an electric shower?
If an under-rated fuse is used it will be overloaded and will keep tripping out. If the fuse rating is too large it will not disconnect the supply quick enough under a short circuit fault condition. To avoid these problems the correct size fuse/mcb must be fitted for the kW rating of the unit in accordance with the I.E.E. regulations. Sizes required are:
•7kW = 30/32amp mcb.
•7.5kW = 32amp mcb
•8kW = 40amp mcb
•8.5kW = 40amp mcb
•9.5kw = 40/45amp mcb
•10.5kW = 45/50amp mcb
