Maintenance 

 
After  servicing,  complete  the  relevant  Service 
Record  section  of  the  Benchmark  Checklist 
located  on  the  inside  back  pages  of  this 
document. To meet with warranty requirements 
the cylinder must be serviced annually. 
 

The  maintenance  of  this  appliance 
must  be  carried  out  by  a  suitably 
qualified 

person 

only. 

It 

is 

recommended to maintain the unit on 
an  annual basis.  Isolate  all  electrical 
supplies 

from 

the 

unit 

before 

commencing 

work. 

Danger 

of 

electrical shock! 

 
1)  Draw  some  water  from  cold  water  tap  and 

retain in container. 

 
2) Isolate cold water mains supply from cylinder. 
 
3)  Briefly open temperature and pressure relief 

valve, assure safe discharge and check that 
valve is not dripping when closed.  

 
4)  Briefly  open  expansion  relief  valve,  assure 

safe  discharge  and  check  that  valve  is  not 
dripping  when  closed.  The  expansion  relief 
valve should be operated regularly to remove 
lime  deposits  and  to  verify  that  it  is  not 
blocked. 

 
5)  Open  hot  water  tap  and  release  remaining 

pressure from unit. 

 
6)  If  the  system  is  drained  completely  for  an 

internal inspection, ensure the hot water tap 
remains  open,  connect  a  hose  to  the  drain 
valve and ensure a safe discharge. 

 
7)  Note  the  set  pressure  of  the  pressure 

reducing valve. Remove cartridge and clean 
strainer  in  water  provided  in  container.  Re-
assemble  pressure  reducing  valve  ensuring 
the correct pressure is set.  

 

8) 

Periodically the immersion heaters should 
be  removed  cleaned  and  the  unit  flushed 
out. Check the O-ring seal for damage and 
replace if necessary. 

 
9) 

Check electrical wiring connections and the 
condition  of  the  cable  of  the  immersion 
heater, the thermostat and the connections 
on the relays. 

 
10)  The  immersion  heater  boss  can  also  be 

used  for  access  to  view  the  internal 
components of the cylinder. 

 
11)  Re-commission unit

 

(see chapter 6). 

 
If the cylinder is not in use for excess of 1 
month,  it  must  be  drained  down  by  a 
competent  person  and  recommissioned 
before use.  
 
Note: The immersion must be switched off 
at the mains before draining the cylinder. 

 

If  replacement  parts  are  required,  please 
see 
Figure 11Figure 12 for part descriptions 
and part numbers.  

 
CLEANING INSTRUCTIONS: Clean outer 
cladding  of  cylinder  with  a  soft  cloth 
dampened  with  warm  water  only.  Do 
not use abrasive or aggressive cleaning 
materials, such as alcohol or petroleum 
based solvents, as this may damage the 
surface of the product. 
 
 
Waste electrical products should not be 
disposed  of  with  household  waste. 
Please  recycle  where  facilities  exist. 
Check  with  your  Local  Authority  or 
retailer for recycling advice.
