MAINTENANCE
Preventative maintenance:
• Check and re-commission the temperature at least twice per year
(Fig. E)
.
• Check the anti-scalding failsafe approximately every two months. Shut off the cold water supply
and check that the hot water shuts off in less than 3 seconds.
• To maximise the reliability of SECURITHERM thermostatic mixing valves over time, and to reduce
the risks associated with Legionella, we recommend an annual check of the following items:
- Non-return valves and filters: de-scale and replace worn or damaged parts.
- Interchangeable cartridge: de-scale internal parts and replace worn or damaged parts.
- Mixing chamber: de-scale.
Maintenance for thermostatic mixers (Fig.E):
If the SECURITHERM is not mixing correctly:
• Check that the hot and cold water pressures are balanced.
• Check the filters
and non-return valves
for signs of wear or for foreign bodies that may cause
blockages.
• Remove and clean the thermostatic cell
.
Maintenance for electronic models:
1. Changing the SOLENOID VALVE:
(Fig. F)
• Shut off the hot and cold water supplies.
• Unscrew the connection screws to remove the faulty solenoid valve.
• Insert the new solenoid valve, making sure that the water circulates the right way (see arrow marked
on the valve body). Insert the filters supplied to protect the solenoid valve from foreign bodies.
• Connect the solenoid valve:
-
Red wire onto the red cross
-
Blue wire onto the black cross
• Reconnect the water supplies (HW and CW) and check that the valve opens and closes.
2. Changing the BATTERY:
(Fig. G)
• A red LED will flash when the battery needs changing:
- Unscrew the screw
to change the battery
, leaving the washer in place.
- Re-assemble, carefully tightening the screw.
MAINTENANCE AND CLEANING
•
Cleaning chrome and stainless steel:
do not use abrasive, chlorine or any other acid-based
cleaning products. Clean with mild soapy water using a cloth or a sponge.
•
Frost protection:
drain the pipes and operate the mixer several times to drain any remaining water.
In the event of prolonged exposure to frost, we recommend taking the mechanisms apart and storing
them indoors..
