extinguish. Check the water temperature and re-check water connections

Maintenance
Precautions
1. The Zip Aquapoint is an unvented electric water heater and a competent
person, familiar with unvented systems, should carry out all servicing and
maintenance
2. Do not remove the cover whilst the unit is connected to the electrical supply
3. The over temperature safety cut-out is located inside the cover. Do not reset
the over temperature cut-out until the cause of its operation has been
diagnosed and necessary repairs have been undertaken
4. Do not use the water heater if it is suspected of being frozen. Switch off the
electrical supply if water ceases to flow and do not switch on again until a
competent person has checked that it is safe to do so
5. The heater should be visually inspected regularly. This is particularly important
if the heater is located in a cupboard, roof space or any other concealed
location. If there is any sign of leaks or seepage the heater should be
isolated from the water supply and switched off from the electrical supply
until a competent person has investigated the cause.
6. Do not block or restrict the discharge from any safety valve
7. Do not tamper with any safety valve
8. If water discharges from any safety valve switch off the electrical supply to
the unit, isolate the water supply and contact a competent person familiar
with unvented systems
9. Please note that lime-scale deposits form more readily at higher temperatures.
Damage or failures caused by the formation of lime-scale are specifically
excluded under the terms of the warranty. To reduce lime-scale formation to
a minimum the unit should always be operated at the lowest convenient
temperature. The ‘E’ temperature setting is recommended.
10. If the unit has been commissioned and is to be unused for more than two
weeks with the power supply still connected the thermostat should be set
to ‘
*
’ to maintain a temperature of approx. 7ºC and protect the unit from
freezing. NB this protection does not extend to connecting pipework.
