INSTALLATION
Circulating fluid in thermal store pipework
• The Torrent Stainless and the thermal store pipework must have completed filling
prior to switching the electricity supply to the PWM controller PCB. If there is no
water in these pipes then there may be significant wear on the PWM pump.
• This can be confirmed by
- Checking the thermal store pipework servicing valves are open
- Loosening the connection points on the thermal store pipework in a systematic
manner and checking for water presence.
- Confirming that the feed and expansion tank has completed filling and the
servicing valve is open.
Cold mains water supply to plate heat exchanger and hot water taps
• Confirm that the CW mains stop valve is open
• Open all HW taps and confirm that the water runs freely and that any air is bled
from the DHW system
• Determine the maximum flow rate obtained and record
• Limited to 26.5l/min for all products
• If flow rate not as expected determine the cause and rectify
- clean inline strainer
- check the flow restrictor is present and not blocked. It is located in the top of
the inline strainer
Power on
• Switch on the Local fuse spur and observe the PWM pump
• Open a HW tap and observe the PWM pump
• The green LED will be constantly lit showing the pump has a power supply and is
running to generate HW
NOTE: -The thermal store will only produce hot water when it is hot enough. A mid
40°C thermal store temperature will provide very little hot water, higher thermal store
temperatures will provide more, 75°C is recommended.
Inline scale inhibitor (if fitted)
• Check power supply
• PWM Controller PCB supplies a maximum of 12vDC/300mA to the Scale inhibition
board. (From J3)
• Check dip switches set correctly
• The correct settings for tube diameter 22mm is switch no. 3 on.
• Switch no. 4 can be either on or off.
• If the switch no. 4 is turned on the output electromagnetic field is generated
harmoniously otherwise the field is generated inharmoniously.

SERVICING AND MAINTENANCE
Annual Servicing
No annual servicing of the Torrent Stainless is necessary.
However, if required, a hot water performance test can be carried out to prove the
appliance is working satisfactorily and within its specification.
We recommend electrical inspections are carried out regularly. Please seek advice
from a qualified electrician.
If it is decided to carry out the above test, the water level in the top cistern should
also be checked and if necessary topped up.
Changing Components
Failed components should be returned during the in-warranty period on return of
the faulty part (normally 12 months) via the local authorised supplier. A nominal
charge of £30 will be made which is refunded in full by Gledhill on receipt of the
original part and proof of purchase.
After this, spares can be obtained direct from Gledhill Spares, or through any of the
larger plumbers merchants/specialist heating spares suppliers.
Help and advice is also available from the Technical Helpline on 01253 474584.
However, all components are readily accessible and can be changed quickly and easily
by the installer using common plumbing/electrical practice.
Note: All maintenance work on the Torrent Stainless must be carried out by a
competent trades person.
After servicing, complete the relevant Service Interval Record section of the Benchmark
Checklist located on the inside back pages of this document.
