Installation and maintenance instructions for uniSTOR 0020111105_00
If the water does not meet the requirements of The
Water Supply (Water Quality) Regulations 2000 (Amend-
ment) Regulations 2007, corrosion damage may occur
on the cylinder.
>
Only use the cylinder to heat potable water.
Electric potential equalisation
If you use an electric immersion heater in the cylinder,
the external voltage may build up electrical potential in
the water which can result in the electrochemical corro-
sion of the electric immersion heater.
>
Make sure that both the hot water and cold mains inlets
on the cylinder itself are connected to the earth line by
means of an earth cable.
>
You must also make sure that the electric immersion
heater is connected to the earth line via the earthing ter-
minal.
Preventing frost damage
You should not turn the gas-fired wall-hung boiler off
completely so that you can still use all of the safety
functions for your heating system. If you want to take
the unit out of operation for a relatively long period of
time in an unheated room at risk from frost, you must
completely drain the cylinder.
Avoiding damage caused by leaks
If there are leaks in the pipework, close off the cold
water stop valve on the safety assembly and notify
a competent person to rectify the leaks.
Preventing damage due to unauthorised changes
to the unit
Changes to the supply lines, relief valve termination, and
expansion relief valve may only be carried out by a com-
petent person!
Avoiding burns and scalds
Install a hot water thermostat mixer in the system
to protect against scalding.
