TYPE 3 VALVES MAINTENANCE

Planned maintenance for Type 3 valves should include the ‘in service tests’ procedure detailed below as well as the procedure

detailed in the general ‘maintenance’ section.
The thermostatic cartridge does not contain any serviceable parts. Therefore, if it malfunctions a full replacement of the cartridge is

required.

IN-SERVICE TESTS

General
The in service tests are meant to monitor and record the continuing satisfactory performance of the thermostatic mixing valve.

PROCEDURE

1. Carry out step 4 (a) to (c) in the ‘Commissioning’ section. Make sure y u are using the same equipment or equivalent.
2. If the temperature has changed significantly from the last test results follow the next steps:
a. Record the change
b. Check if the filters are clogged and clean them accordingly (refer to section ‘Maintenance, filter cleaning instructions’)
c. Check that the check valves located in the flexible hoses are in good working conditions. Replace the flexible hose\s if necessary.
d. If the mixed water temperature still differs significantly, re adjust the mixed water temperature (refer to section ‘Adjusting the

mixed water temperature’).
3. If the temperature has not changed significantly, complete the procedure [Commissioning, step 4 (d) to (f)]
4. Pay attention to the final mixed water temperature recorded in Commissioning, Step 4 (e). If it exceeds the maximum mixed water

temperature stated in the ‘Maximum stabilized temperatures recorded during site tests’, or if it exceeds the temperature of the last

test by more than 2C˚ proceed to the ‘troubleshooting’ section.

ADJUSTING THE SETTINGS WITH THE REMOTE CONTROL

If necessary, the sensor settings can be adjusted as following:

Shut off the water supply. In order to adjust the sensor with the remote control, hold the remote control straight

in front of the sensor in a distance of about 6-8” (15-20cm). Choose the function you want to adjust by pressing

once on one of the function buttons. After pressing once on a specific function button, a quick flashing of the LED

at the front of the sensor will occur. At this stage, you can change the setting by pressing the (+) or the (-) buttons,

every push will increase or decrease one level. After finishing the adjustment, turn the water supply back on.
