OPERATIONAL FAULTS

Operational  faults  and  their  possible  causes  are 

detailed in the Fault Finding section of this book. It 

is recommended that faults should be checked by 

a competent installer.

The  air  volume  within  the  expansion  vessel  will 

periodically require recharging to ensure expanded 

water is accommodated within the unit.

 

A discharge 

of  water 

INTERMITTENTLY

  from  the  expansion 

valve will indicate the air volume has reduced to 

a point where it can no longer accommodate the 

expansion.

 

FAULT FINDING & SERVICING

IMPORTANT

•

 

After servicing, complete the relevant 

Service Interval Record section of the Benchmark 

Checklist located on page 19 and 20 of  this 

document.

•

 

Servicing should only be carried out by

  

competent persons in the installation and

  

maintenance of unvented water heating    

 

systems.

•

 

Any spare parts used 

MUST

 be authorised

  

POTTERTON GOLD parts.

•

 

Disconnect the electrical supply before 

 

removing any electrical equipment covers.

•

 

NEVER bypass any thermal controls or 

 

operate system without the necessary  

 

 

safety valves.

•

 

Water contained in the POTTERTON GOLD    

 

cylinder may be very hot, especially following

 

a thermal control failure. Caution must be 

 

taken when  drawing water from the unit.

SPARE PARTS

A full range of spare parts are available for the

POTTERTON GOLD cylinder range (See Table 4 Page  

17 ). Refer to the technical data label on the unit to 

identify the model installed and ensure the correct 

part is ordered. You will need to quote the serial 

number, which is printed on the data label.

FAULT FINDING

The fault finding chart (Table 5 Page 18) will enable 

operational faults to be identified and their possible 

causes  rectified.  Any  work  carried  out  on  the 

POTTERTON GOLD cylinder unvented water heater 

and its associated controls 

MUST

 be carried out by 

a competent installer for unvented water heating 

systems. In case of doubt contact

 

service support 

(see contact details on back page).
