7.8 Replace Heat Exchanger

The heat exchanger is located at right side of

the unit under the side panel. Under normal

conditions the heat exchanger should not need

to be replaced.

Replace it if the dehydrator has been dropped

or otherwise damaged such that the heat

exchanger is leaking air.

7.9 Filter Bowl Replacement

Verifythatyouhavethelatestlterbowl

assembly as shown below. If you do not have

thislterbowlassemblyyouwillneedtoreplace

this assembly with item 5 from the Three-Year

Recommended Dehydrator Spare Parts list. If

to section 7.10 and 7.11.

7.10 Replace Water Filter Element - 6000 hour

Maintenance

When ambient room air is compressed in the

dehydrator compressor, liquid water is formed.

This liquid water must be removed in order to

allow the membrane dryer to function at its peak

efciency.Astheairexitsthecompressor,itis

cooled in the heat exchanger and then enters

intothewaterlter.Theairswirlsaroundthe

insideofthelterbowl,separatingtheliquid

wateroutonthesidesofthelterbowl.A5

micronlterisalsoprovidedinthewaterlter

topreventwaterdropletsfromexitingthelter.

This5micronlteralsoltersoutanydust

particles or other contaminants which would

lessentheefciencyofthemembranedryer.

Toreplacethelterelement,twistandremove

thelterbowlfromthecasthousing.Unscrew

thelterelementfromthecastlterhousingand

replacewithanewlter.Donotattempttoclean

thelterelement.Ifitisnecessarytocleanthe

lterbowl,useamildsoapandwatersolution

and rinse with water. Do not use solvents.

Reassemble the unit by reversing the above

procedure. Check for leaks by turning the unit

on and applying a dilute detergent and water

solution at the bowl/housing seal and at the hose

ttingswhichwerereconnected.Ifnoleaksare

found, the unit is ready to return to service. If

leaks are located, repair the leak and recheck

foradditionalleaks.Leakingttingsmustbe

repaired or the unit will not function properly and

can result in damage to the transmission line

system.

7.11 Replace Coalescing Filter Element

Thecoalescinglterislocateddownstream

fromthewaterlter.Itsfunctionistoremove

any “water fog” which may still be present in the

airleavingthewaterlter.Thecoalescinglter

trapsanyneliquidwaterparticles,including

aerosols and causes them to coalesce into

larger droplets. These droplets fall to the bottom

of the bowl and are blown out and carried to the

compressor head, where they evaporate.
