Ozroll OZS251E, Installation Manual

I2. Tank Anode replacement ( Refer Section F4 )

CAUTION :

 Tank anode replacement MUST be done by a qualified person only. The homeowner should NOT AT-

TEMPT to replace the anodes

Sacrificial magnesium anodes are inserted in all Our storage tanks and these preferentially corrode to increase 
the lifespan of  the tank. Eventually these anodes can wear away and require replacement

Replacement of  the anode should be carried out approximately every 5 years. There are 2 anodes, both anodes 
should be replaced at the same time. The anodes are located under 2 plastic covers on either side of  the T / P 
valve located on the top of  the tank.

CAUTION :

 The tank MUST be completely drained empty of  water and completely  electrically isolated from the 

Mains power supply PRIOR to replacing the anodes

The anodes can be carefully drawn out by unscrewing the 2 nuts which are part of  the anodes at the top of  the 
tank and lifting them out through the top of  the tank. Depending on the location of  the installation, it may be 
possible to remove the anodes without moving the tank. If  there is insufficient height above the tank to safely 
remove the anodes then the tank may need to be moved so there is sufficient room to carry out the process

I3. Replacement of the Electric Booster Element

CAUTION 

: Electric Booster replacement MUST be done by a qualified person only. The homeowner MUST NOT 

ATTEMPT to replace the electric element. The system must be COMPLETELY electrically isolated and drained 
of  water before replacing the element

On 250 litres and 300 litres storage tanks, the booster element must be replaced with a 2,400 watt booster ele-
ment. On 400 litre storage tanks, the booster element must be replaced with a 3,600 watt booster element

Section F7 explains how the booster element is fitted. Removal of  the element is the reverse of  this operation. 
Care should be taken when removing the old element to prevent damage to the threads of  the 4 locating pins. 
In addition, care should be taken to ensure the pins are not damaged or bent. 

SAFETY WARNING :

 Extreme Caution should be taken when replacing the glazing of  the collectors. This presents 

a significant hazard and is recommended to be undertaken by a Our Solar authorized technician.

I4. Replacement of Collector Glazing

SAFETY WARNING:

 Extreme caution should be taken when replacing the glazing of  collectors. This presents a 

significant hazard and collectors must only be replaced by one of  our authorized technicians.  

I5. General Maintenance Tasks

The  SOLAR  COLLECTORS  generally  do  not  require  maintenance.  However,  they  do  need  to  be  kept  clean  to 
maximize performance. It is recommended that periodically, depending on dust / dirt which may have settled 
on the collectors, the collectors should be wiped down with a cloth and warm soapy water followed by rinsing 
with water.
