MAINTENANCE
• Check the calibration at least twice a year (Fig. C & D).
• We recommend checking the anti-scalding failsafe every two months and as often as necessary depending
on the water quality. Shut off the cold water and ensure that the hot water stops within 2 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:
1. Inter-changeable cartridge: de-scale internal parts and replace worn or damaged parts.
2. Mixing chamber: de-scale.
3. Replace the control lever and tighten to 13 Nm +/-1 (Fig. F).
• In the event cartridge malfunction, please replace (Fig. G).
• We recommend checking that the thermostatic cartridge en "seats" are waterproof twice a year
and as often as necessary depending on the water quality.
To check the seats:
1. Shut off the hot water: check that there is no cross flow of cold water into the hot water system.
2. Shut off the cold water: check that there is no cross flow of hot water into the cold water system.
If there is cross flow, clean the seats or replace the thermostatic cartridge.
MAINTENANCE & CLEANING
• Cleaning chrome, aluminium 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/tap/valve 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.
