CAUTION:
Do not operate the system without a suitable
filter in the return air duct system. Always
replace the filter with the same size and type.
Toensureoptimumperformanceandtominimizepossible
equipment failure, the following maintenance tasks should
be performed periodically on this equipment:
1.Theairlterinstalledwiththesystemshouldbechecked
and cleaned or replaced twice per year.
2. Check the coil, drain pan, and condensate drain line
for cleanliness at the start of each heating and cooling
season. Clean as needed.
Air Filter
Air filters are not supplied as an integral part of this
coil; however, an air lter kit is available. Refer to the
ReplacementPartsListforavailablepartnumbers.
The lter must be installed upstream of the coil and
inspected frequently. When the filter becomes clogged
with dust or lint, it should be replaced (disposable type)
or cleaned (washable type). It is recommended that filters
be inspected and replaced at least twice during the year.
Generally it is best to replace or clean the filters at the
start of each heating and cooling season.
Condensate Drain
CAUTION:
The coil must be level to ensure proper
condensate drainage. Improper condensate
disposal may result in structural damage,
premature equipment failure, or possible
personal injury.
• Methodsfordisposingofcondensatevary according
tolocalcodes.Refertolocalcodesorauthorityhaving
jurisidiction for restrictions and proper condensate
disposal requirements.
• Allcondensatepanshaveprimaryandsecondarydrain
connectionstomeetFHArequirements.Iftheapplication
is located in or above a living space where damage
mayresultfromcondensateoverow,aseparate3/4
inch drain must be provided from the secondary drain
connection and a secondary drain pan must be installed
undertheentireunit.Runsecondarydrainlinestoa
place where they are noticeable if used.
• Thecoilcondensatepanisdesignedwith3/4”NPSC
drainconnections.UseaPVCorsimilarmaterialtting
to attach the drain line to the pan. NOTE:Thetting
should be hand tightened only. Overtightening may
crack the drain pan and cause condensate to leak.
• The drain pan MUST be drained with eld supplied
tubingorPVCpipeandadequatelytrapped.
IMPORTANT: Failure to install a trap may result in
condensation overflowing the drain pan, resulting
in substantial water damage to surrounding area.
• Primethetrapwithwater.Insulatethedrainifitislocated
in an unconditioned space, and test the condensate line
for leaks. Consult local codes for additional restrictions
or precautions.
• Routethelinestoasuitabledrain,avoidingsharpbends
andpinchingofthelines.Thedrainshouldmaintaina
minimum horizontal slope in the direction of discharge
ofnolessthan1”verticalforevery10ftofhorizontal
run.
• During system checkout, inspect the drain line and
connections to verify proper condensate drainage.
