Section 5
Maintenance
The dehydrator requires maintenance
semiannually and after each 6000 hours of
operation to ensure continued reliable operation.
Danger:
Service personnel should observe all
safety regulations. Do not perform
maintenance on equipment without
rst turning off the main power supply.
Under certain conditions, dangerous
potentials may exist when the main
power supply controls are in the off
position. Only qualied technicians
should attempt to effect maintenance
or repairs on electrical equipment.
Semi-Annual Maintenance. The semi-
annual maintenance consists of a preventive
maintenance inspection and replacement of
thecompressorairlter.Thesetaskscanbe
performedeasilyintheeldasdescribedbelow.
6000 hour Overhaul. A dehydrator overhaul is
required after the compressor has run a total of
6000 hours, as indicated on the compressor run
time meter. The dehydrator overhaul includes
acompressoroverhaul,waterlter,high
temperature tubing and hose clamps.
The dehydrator overhaul kit, see Section
7.0, includes all the necessary parts and
instructions. Or, if you prefer, CommScope
offers a dehydrator overhaul service. Contact
CommScope Technical Service. Telephone
numbers are found in Section 9.
Refer to Sections 7.9, 7.10 and 7.11 for
procedurestoreplacewaterlterelements.
InCaseofDifculty.Ifthedehydratorwillnot
operate or if there are other problems, refer to
the troubleshooting procedures in Section 6.
5.1 Semi-Annual Preventive Maintenance
Inspection
Inspection includes checking for loose
ordamagedhoses,ttingsandelectrical
connections. Check the following items:
Water Filter and Coalescent Filter and
Elements
Verify there is no water build-up in the
lterbowls.Ifthereiswater,refertothe
troubleshooting procedures in Section 6 for
corrective action. Replacement of the water
lterandcoalescentlterandtheirassociated
elements and bowls is covered in the parts
replacement section of this manual. Refer to
Section 7.
Electrical Connections
Check for loose or corroded electrical
connections. A loose terminal can cause erratic
operation and unnecessary downtime. Check
the screw-on and push-on terminals and tighten
as required.
Ground Wire
Check for proper ground wire connection to
protect operations personnel. A green ground
wire is attached between the power terminal
strip and the dehydrator chassis. The ground
lug screw or stud nut must be tight to provide a
proper ground.
Hour Meter
Check the run time meter to determine the duty
cycle of the dehydrator. If the dehydrator has
been running more than 10% of the time, check
for system leaks. Also check to see if it is time
to schedule the 6000-hour maintenance.
5.2 Replace Compressor Air Filter
Theairlterprotectsthecompressorfrom
contamination and extends the service life of the
compressor. It is made of open cell material
and should be replaced every six months or
more often if the dehydrator is located in a dusty
environment.
Carefullypullofftheltercoverandremovethe
lterelement.Installthenewlterelementand
replacetheltercover,beingcertainthatitis
completelyseated.Toreplacethelterhousing,
unscrew the housing from the compressor head
andreplacewithnewlterhousing.
