8. Braze the individual connections with dry nitrogen flowing
through the joints.
IMPORTANT NOTE:
To prevent internal oxidation and scaling from occuring,
braze all connections with dry nitrogen flowing through
the joints.
9.Installthegrommetinthedoorcutout.Verifythegrommet
is evenly aligned around the tube and securely positioned
in the door cutout.
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 overflow, 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 NOTE:
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.
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.
COMPLETING THE INSTALLATION
1. Check the system for leaks, including the lineset and the
brazed joints.
2.Evacuatethesystemofmoistureandnon-condensables
to prevent low efficiency operation or damage to the unit.
Thesuggestedrangeofevacuationis350-500microns.
3. Charge the system with refrigerant. Please Refer to the
outdoor unit installation manual for additional charging
instructions.
4. Install the coil access door (if removed).
5.Properlydisposeofallremovedparts.
6. Apply power to the unit.
MAINTENANCE & SERVICE
WARNING:
ELECTRICAL SHOCK, FIRE OR
EXPLOSION HAZARD
Failure to follow safety warnings exactly could
result in serious injury or property damage.
Improper servicing could result in dangerous
operation, serious injury, death or property
damage.
• Beforeservicing,disconnectallelectricalpower
to the equipment.
• Whenservicingcontrols,labelallwirespriorto
disconnecting. Reconnect wires correctly.
• Verifyproperoperationafterservicing.
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.
