Litepipe » Cleaning & Maintenance »

Litepipes in Warehouse The Midtherm Litepipe system is carefully designed and manufactured to be as maintenance free as possible.

The Litepipe is a sealed unit and all assemblies (dome, diffuser, flashing) have individual seals and all joints are taped to stop insect and dust infiltration. The design and shape of the dome and flashing prevents the build up of outside debris.

The issue of condensation is eliminated at roof level by fitting a brushed nylon gasket on installation. Internally, Litepipes are sealed at the ceiling point to prevent warm moist air in the room below migrating up the tube. A special dome seal allows outside air to mix with air in the tube, thereby eliminating any air temperature contrast that contributes to condensation.

To eliminate any possibility of leakage, all roof-flashing components are made of seamless, one-piece construction and do not need to be 'flashed in' using lead strip. Over 20 different roof flashing types are available to match your particular roof type. On commercial applications roof flashing types vary.

If access is required for cleaning or internal equipment maintenance then Midtherm Engineering always recommends you to have the correct access and safety procedures in place before any work is carried out.

Cleaning & Inspection Guidelines

If cleaning of the system externals such as ceiling diffuser and roof dome is required then it is recommended that non-abrasive cleaning fluid and cloths are used.
Only use safe access methods when attempting to reach the polycarbonate roof dome. Approved roof ladders or scaffold access is always preferable.
When attempting to clean the polycarbonate roof dome first lightly brush away any leaves or debris attatched or around the general area. Then wash the external surface of the dome using the appropriate cloth and cleaning fluid.
Unless it is strictly necessary or a Midtherm engineer is present then it is not recommended to remove the roof dome for internal cleaning. Once the roof dome is removed airborne particles or the cleaning chemicals used may compromise the integrity of the system.
When checking system integrity enter the roof space and look for beams of light escaping the system. If any are found these must be taped using a suitable aluminium tape. Escaping light can attract many types of insects and these may enter the system and collect within the ceiling diffuser.
If access is required to the base of the system, this can be attained through removing the ceiling mounted light diffuser. This is attached via plastic ties operating on a ratchet system. Carefully prise the diffuser away from the ceiling ensuring no damage is caused to the diffuser assembly or ceiling area.
In the case of an integral lighting kit being installed and access being required to facilitate a light bulb change it is our recommendation that soft cotton gloves are used. Touching the silverised material core can affect the overall performance of the lighting system.
When replacing the light diffuser ensure that the ratchet ties are correctly located within the guide holes provided. Incorrectly aligning the ties to the holes may damage the system.
