PARTICULATE FILTER REPLACEMENT
a)
Open the filter access door with the appropriate tool (Phillips screw driver) to avoid stripping of screws;
b)
Carefully slide pre-filters and high capacity filters along their support channels, Slide clean filters gently into place;
c)
Ensure Dust Filters are replaced as per airflow indications;
e)
If encountering difficulties, confirm that there are no obstructions in the filter track;
f)
Hi-Efficiency filters must be replaced as per airflow arrow on the filter casing;
g) HEPA filters should be installed with gaskets facing up to seal on the section above the filter.
For critical applications, a secondary seal can be applied using continuous bead of removable sealant. (Part# AR321)
This would be applied to the middle of the gasket in a continuous bead prior to putting the HEPA into the system and then
Inserting pressure seal rods
h) The RNP systems are equipped with a HEPA pressure sealing mechanism. The easiest and most effective way to change the HEPA filters is
with the unit lying down on its back. Two or more people will be required to do this safely. Once lying down the pressure sealing mechanism rods
are to be pulled out to release the seal. There are loops on the rods to help pull. If it is difficult to remove please use a tool for additional leverage.
Please note it critical for these filters to be tight and secure to avoid by-pass so this is completely normal. If secondary sealant was applied please
remove this prior to installing new filter.
i)
Care must be taken not to damage the exposed portions of the new HEPA filter. DO NOT bend aluminium separators as this will obstruct airflow.
