Note
When needed, spare parts can be ordered. To
be sure that you receive the correct spare parts,
look at the data plate for the full serial number,
the water heater model. Use this information

9.1

Performance check

Check if the performance of all components is
correct:
1. Make sure that the water heater cycle
operates correctly.
2. If applicable, make sure that the T&P valve
operates correctly.
3. Open the T&P valve pressure relief and
make sure that water flows from the outlet.
Warning
Hot water can come out of the T&P valve.
5. Make sure the pressure relief connection of
the inlet security group operates correctly.
Open this pressure relief and make sure that
water spurt out.
9.2

Water-side maintenance

To do water side maintenance:

Inspect the anode (see 9.2.1)

Descale the tank (see 9.2.2)
9.2.1 Inspect the anode
The life cycle of the anode is determined by the
quality and the quantity of the water that flows
through the water heater. Inspect the anode at
least once a year to make sure that the tank is
protected against corrosion.
To inspect the anode:
1. Close the pressure reducing valve in the cold
water supply.
2. Open the nearest hot water tap to reduce the
water pressure in the water heater.
3. Use a wrench to loosen the anode.
4. Take the anode out of the water heater.

5. Inspect the volume of the anode. When the
anode is consumed for 40 % or more replace
the anode.
Note
If the anode needs to be replaced, always use
an anode of the same type. Please refer to the
type and the serial number on the data plate.
6. Place the anode in the water heater.
7. Use a wrench to fasten the anode.
8. Make sure that the connection is watertight.
Note
Never install an anode isolated from the
metal tank.
9.2.2 Descale the tank
Use a descaling agent if necessary remove lime
and dirt from the tank. Contact Lochinvar
Technical support for advice about which
descaling agent to use. Lochinvar service
department can carry out this function if required,
please contact us for further information.
9.2.3 Finalization
When all maintenance activities are finished,
place the outer door back on the water heater.
After that:
1. If necessary, fill the water heater (see 8.7.1).
2. Turn on the water heater (see 8.7.3).
