Guarantee - Unvented hot water cylinder
The OSO stainless steel inner vessel is guaranteed against material defect or manufacturing faults for a period of
10 years from the date of purchase. All other parts including, but not limited to factory fitted electrical elements
(damage caused by lime scale excluded), thermostats and valves are guaranteed against material defects or
manufacturing faults for 2 years from the date of purchase. In the event of a replacement component being
required OSO Hotwater will supply such part(s) free of charge and freight paid, on condition that the defec-
tive component is delivered, fright paid to OSO Hotwater within 2 weeks of written notice being given to OSO
Hotwater of the defect. Such replacement parts shall be guaranteed under the terms of this guarantee to the
unexpired period of the aforementioned 2 year period.
Important: When installing water treatment equipment adding chemicals (inhibitors) such as hypochlo-
rite the warranty is void.
This warranty is conditional upon the OSO cylinder being installed in compliance with the OSO Installation &
Maintence Instructions, all current legislation, codes of practice and regulations governing the installation of
unvented hot water cylinders in force at the date of installation and provided that:
1.
The water supply to the cylinder shall be in accordance with European Council Directive 98/83 EC at the
date of installation and not be fed from a private water supply. Pay special attention to:
Chloride content:
Sulphate content:
Combination Chloride/sulphate:
2.
The OSO cylinder is filled with water before turning the electricity supply on to the heater elements.
3.
If the newly fitted water heater is not in regular use then it must be flushed through with fresh water for at
least 15 minutes (open at least one hotwater tap) once per week, during a period of at least 4 weeks.
4.
The mains water supply complies with EU standards current at the date of installation and is not fed with
water from a private supply.
5.
The OSO unvented cylinder has not been modified in any way other than by OSO Hotwater and is only
used for the storage of potable water.
6.
No factory fitted parts have been removed for unauthorised repair or replacement.
7.
Defects caused by frost, excess pressure, salt dehardner process, trancient voltage, lightning strikes or
incorrect installation, repair or use, are not covered by this warranty. A laboratory evaluation of possible
defects can be ordered by the user, however the user must pay for this where the above mentioned condi-
tions have not been fulfilled. Evidence of the purchase date and the date of supply must also be submitted
with your claim.
8.
This guarantee does not confer any rights other than those expressly set out above and does not cover
any claims for consequential loss or damage. This guarantee is offered as an extra benefit and does not
affect your statutory rights as a consumer.
Annual control - first time after approx. 3 months:
1.
Open safety valve. Check that water flows freely to drain. Close valve.
2.
Anode (if fitted): Shut off mains water supply and release pressure by opening a HW tap. Check
anode, replace if necessary. Anode is checked by unscrewing CW and HW feed pipes to UX
valve and unscrew the valve from the water heater. Lift valve and check anode pipe. Install new
pipe if anode material has been eroded away.
3.
Check that pipe connections and heating element in el. box are not dripping. Shut off power
supply before removing el. box cover! At the same time check el. connections. Tighten if neces-
sary. Refit el. box cover before turning power supply on.
Troubleshooting:
Not enough hot water: Turn knob on UX valve fully open. Check power supply. Press reset button
(see el. connection on p. 7) turn off power supply first! Check heating element. Check for leaks in
taps or pipes (hissing noise in water heater when all taps are closed).
SV 9 bar dripping: CW pressure exceeds 6 bar. Install reduction valve and an AX12 exp. vessel if
necessary. Alternatively replace safety valve.
