Work order:
1. Undo bolts from the cover.
2. Remove cover and the gasket.
3. Inspect the tank and remove the loose scale deposits and contamination.
4. If the scale cannot be removed by hand, descale the storage water heater with a
descaling agent. Contact the supplier/manufacturer for advice on what descaling
agent to use.
5. Close the cleaning opening. To avoid damage to the tank tighten the bolts, that
fasten the lid, with a torque no greater than 50 Nm. Use suitable tools for this.
Checking anode
The anode ensures the protection of the tank by sacrificing himself. Insufficient anode
material may lead to poor protection and, hence, leakage of the tank.
Storage water heater
1. Loose the anode.
2. Check the diameter of the anode in different places. The diameter must be at least
60% of the original
1” diameter.
3. If the diameter is less than the minimum, the anode must be replaced. Please contact
the supplier/manufacturer to order new anodes.
4. Mount the (new) anodes.
Importent
Anode must make electric connection in the tank. Make sure that the thread is not
isolated from the tank.
Electrical heating element
1. Remove the element from the tank.
2. Check the diameter of the anode in different places. The diameter must be at least
60% of the original 1” diameter.
3. If the diameter is less than the minimum, the anode must be replaced. Please contact
the supplier/manufacturer to order new anodes.
4. Mount the (new) anodes.
Checking heating element
The electrical heating element should be free of scale and lime build-up. The build-up of
scale and lime prevent proper function of the element. The build-up of scale and lime
may lead up to failure of the element.
Note
The first check of the elements must be done after 3 months.
