Do not turn off the power supply cir-
cuit breaker or pull out the unit power
cord during unit operation. This may
causeelectricalhazardsand/orafire.
Keep the power supply circuit breaker
and power plug free from any type of
debris.If using a power supply cord, be
sure to connect to plug firmly. This will
minimizetheriskforelectricalshockor
any other type of electrical hazard.
Depending on the electrical specifi-
cations of your unit, use only 230V/
60Hz or 115V/60Hz power supply.
Failure to do so may result in electri-
cal problems or hazards.
Power supply wires must be located
in areas where they will not be dam-
aged or cut.
Never insert any type of object into
the outdoor unit fan. Because the fan
rotates at a high speed, this may
cause injury.
Be sure that the indoor and outdoor
units are not in operation when discon-
necting the power supply to the unit.
Any type of repairs or maintenance
done to the units must be done by a
professionally licensed contractor.
Any unqualified person should not at-
tempt to repair the units themselves.
Be sure that your hands are not wet
when touching any of the operation
buttons on the indoor unit.
Be sure that the outdoor unit is free
and clear of any debrisaroundtheout-
side of the unit. Do not place or lean
any items on the unit.
Use 230V/60Hz or 115V/60Hz
power supply only .

ensure that the plate is level. Once the plate is level, mark holes that will be used to
holdplateonthe wall.
lRemoveplateand drillmarkedhole atadepth of 1.75inches.

lOnce mounting plate is securely fastened to the wall, then locate an area on the wall for the access hole for the refrigeration
line/condensateline/wiringbundle.
2. Access hole for refrigeration lines/condensate drain line/wiring bundle.
lThesedirectionsmustbefollowedatleastforthecondensatedrain line.Theremust

lDecide on a location for the access hole according to the location of the unit.
lDrill an approximately 2.5 inch hole, making sure that there is a tilt downward of a 1/4
inch.Thiswillensurethatproperdrainageismaintainedforthecondedsatedrainline.
(Ifyouarenotusing rearaccessfortherefrigeration linesandwiring, holewill does
not need to be as large.)
lIt is recommended that a wall sleeve of some sort (i.e. PVC pipe) be used to keep the hole neat and tidy.
Note:The shape ofyourmountingplate may be different from
the one above, but installation method is simllar.

Installation instructions
3. Indoor unit refrigeration line installation
lThe refrigeration lines and wiring can be routed to the outdoor unit in a number of ways (left or right from the back of the
unit), by using the cut-out access pieces on the casing of the unit.
lBendtherefrigeration lines carefullytothe requiredpositonin ordertobe aligned withthedrilled hole.
lAfterconnectingrefrigeratonlines(seedirectionsbelow),installthe condensatedrain line(see page21+24fordetailed
instructionsonconnectingcondensatedrainline).Thenconnectallwiring(seepages25-27fordetailedinstructionson
wiring).Afterallconnectionsaremade,bundletherefrigerationlines,wiring,andcondensatedrainlinetogetherusinga
thermalinsulationandvinyl/ducttape.
Refrigeration lines insulation:
lItisimportantthat boththeliquidand suction
refrigeration lines areindividuallyinsulatedtoensure
thattheydono sweatand alsoto maintainproper unit
capacities.This isnecessarysincetherefrigerationis
meteredfrom theoutdoorunitandwill producecondensationonbothrefrigeration
linesifnotproperinsulated.
Refrigeration lines/Condensate drain line/wiring bundle thermal insulation:
lPlacethecondensatedrainlineundertherefrigerationlines.
lInsulationmaterial shouldbeapolythenefoam thatisapproximatelya1/4
inchwallthickness.
lCondensatedrainlineshouldhaveadownwardslopeatalltimestoensure
properdrainage. Do not allow the drain line to be twisted, horizontal or the
endof the linebe immersed inwater. Ifan extension isadded to the drain line,make sure thatit is also properly insulated.
Connection of refrigeration lines:
lDonot use contaminated or damagedcopper tubing for refrigeration lines.If any of the tubing,
evaporatoror condensercoils havebeen exposedto theair formore that15 seconds,it is
importantthatthey are vacuumedandpurged with field-suppliedrefrigerant.Do not remove
plasticor rubberplugs andbrass nutsfrom thevalves, fittings,tubing, orcoils untilthey are
ready to be connected.
lUse proper tubing cutters to cut the refrigeration lines, advancing the blade of the tubing cutters
slowly.Extraforceorimproper cutting will causetubingdistortionand also extra burring.
lOncerefrigeration tubes are cut, removeburrs from cut edges witha remover. This will avoid
unevennesson the flare faces, which couldcauseagasleak.Holdtheendsofthepipes
downwardtopreventmetalfrom going into the tubes.
lInsertthe flarenuts, mountedon theconnection endsof boththe indoorand outdoorunits onto
the ends of the copper tubing.
lThe length of the pipe protruding from the face of the flare die is determined by the particular flaring tool that will be
used.
lFix the pipe firmly on the flare die. Match the centers of both the flare die and the flaring punch, and then tighten the
flaring punch fully.
lOnce flaring is complete, connection of the tubing is ready. Align the center of the tubing and tighten the flare nuts
usingatorquewrench.
