Installation Instructions
Only a qualified heating engineer should install this product.
- Locate a suitable section of your boiler’s flow pipe for the air-separator to be installed, allowing for access and servicing. The Airliminator should always be installed on the flow from the boiler. If in doubt contact for further advice.
- Isolate heating system and drain down
- Mark the pipe, using a suitable pencil or marker pen and cut out the marked section and remove burrs.
- Fit the diverter onto the sections of cut pipe, ensuring the arrow direction on the part follows the heating system flow.
- Tighten the compression nuts to ensure a watertight seal.
- Fit the Airliminator body to the diverter by hand tightening the retaining ring (Do not over tighten). The Airliminator body must be installed vertically.
- Refill the heating system ensuring that the correct amount of corrosion inhibitor is added.
- Vent as required by using the Top Air Bleed Valve.
Annual Servicing Requirement
To get the best out of your Airliminator, an annual check is recommended.
- Remove vent cap, and test vent pin until system liquid passes.
- If the system fluid is clear, and the magnetic system filter (if fitted) is serviced and found to be satisfactory, no further servicing is required.
- If however the system is heavily soiled, we recommend that it should be drained to allow the Airliminator body to be removed from the system and checked for build-up of sludge/debris.
- Once drained, unscrew the top section of the body to remove the float assembly and clean, taking care not to damage any components or seals.
- Open the base cap to remove and check the stainless steel particulate filter.
- Rinse down both of the removed pieces, ensuring any sludge/debris is disposed of correctly.
- Check seals for damage and re-assemble
- Re-attach the body to the diverter and refill the system in compliance with BS7593:2019.
- Vent the Airliminator once filled to check operation.
WARNING: Please observe the safety instructions provided in this document. This Care and attention should be taken at all times during installation and servicing.
Troubleshooting
Problem 1: Water is leaking from the vent cap
Solution: Turn off the system, isolate the Airliminator, and:
- Float arm and pin for debris
- Check all seals.
- Check the isolation valve nuts to ensure they are fully tightened.
- Check the diverter retaining ring is firmly tightened and not cross threaded.
Problem 2: Poor flow through the Airliminator
Solution: Clean the particulate filter when reduced flow is noted.
