Handling
Care must be taken when transporting, storing and installing the equipment:
• At least two people should li the unit to prevent injuries.
• The unit must be stored in a dry area and must never be dropped during handling.
• Packaging should only be removed at the installation location.
• The unit must be installed on a level floor with the required load bearing capability. Installation,
servicing, maintenance and repair must be carried out by a competent person.
• All electrical wiring must be carried out by a qualified electrician and be installed in accordance with
current I.E.E Wiring Regulations.
• A lack of safety devices can lead to potentially fatal injuries, all necessary safety devices must be
installed correctly in the system. The use of an electric immersion may lead to the build up of electrical
potential in the water. This can in turn cause corrosion of the immersion. To prevent this, ensure the
immersion heater, and the hot and cold pipework are correctly bonded and connected to the earth
line.
• If plastic pipes are used they must be approved temperature resistant to 95°C at a pressure of 10bar.
A thermostatic mixer should be installed in the system to prevent the risk of scalding. If there are leaks found
in the system, shut off the cold water stop valve from the main supply and contact a competent person
immediately.
