1. Safetv Labelinq and Siflnal Words Danger,Warningand Caution

ThesignalwordsDANGER,WARNINGandCAUTIONareusedtoidentifylevelsofhaz- ard seriousness.The signalword DANGERis onlyusedon productlabelsto signify an

immediatehazard.The signalwords WARNINGandCAUTIONwill beused on product labelsandthroughoutthis manualand othermanualsthat mayapplyto the product.

2. Safe Installation Requirem ents

Installation or repairs made by unqualified persons can result

in hazards to you and others. Installation MUST conform with local building codes or, in the absence of local codes, with the

National Electrical Code NFPA70-1990 or current edition.

The information contained in this manual is intended for use by a qualified service technician familiar with safety proce-

dures and equipped with the proper tools and test instru- ments.

Failure to carefully read and follow all instructions in this

manual can result in unit malfunction, property damage, per- sonal injury and/or death.

• Seal supply and return air ducts.

• Check to see that filters are installed correctly and are the proper type and size.

NOTE:It isthepersonalresponsibilityandobligationofthecustomertocontactaqualified installerto ensurethat theinstallationisadequateand conformsto governingcodesand

ordinances.

CAUTION

Do NOToperate unit in a corrosive atmosphere containing chlorine, fluorine, or any other corrosive chemicals.

3. Locatinq & Installinq The Unit

The unitis designedfor outdoorinstallationonly.Placethe unit on a platformatground level. The unitmay be installedon a concreteslabof 48" (1219mm)x 48" (1219mm) dimensions. Cement blocks on a 3" sand footing willalso work. The slabor blocks

SHOULDNOT bein contactwith any partofthe structure. Checklocalcodescovering zoning,noise, platforms,etc..

Ifpracticalavoid locatingnexttofreshair intakes,ventorbedroomwindows. Noisemay carryintotheopeningsand disturbpeopleinside.

Avoid installationsunderroof overhangswithoutguttering. Waterdrainingfromthe roof ontotheunitcould produceexcessivenoise,andmaycauseicetobuildupon coil orfan.

Clearances Minimum clearances,as specified in FIGURE1, MUSTbe maintainedfrom adjacent

structuresto provideadequateaircirculationand roomforservice personnel. While minimumclearancesare acceptablefor safetyreasons,theymay not allowade-

quateaircirculationaroundtheunitforproperoperation.Wheneverpossible,itisdesirable toallow additionalclearance,especiallyaroundthe condenserinletand dischargeopen-

Installing Duct Collars Ductcollarsaresuppliedwiththeunitand areattachedtothesupplyandreturnopenings

withthe flanges to theinsideand mustbe reversedbeforeunit'sinstallation.

1.Remove the screws from the collars and reverse them so the flange isto the outside.

2. Make sure when pushing the collars into place that the "V" flange of the collars seats into the supply and return holes securely.

3. Re-install screw in each collar so it goes through both of the holes in the collar end. It does not matter how the ends of the collar overlap

in order to accomplish this.

CAUTION

The unit must be installed as level as possible, with a maximau slope no greater than 1/8" per foot (10mm per meter). For side to side

leveling, the condensate drain side of the unit MUST always be lower to provide proper drainage.

The unit MUST be situated in such a way as to provide safe access for servicing.

The platform may be made of either concrete or pressure treated wood and MUST be level and strong enough to support the unit's weight.

Position platform separate from the building's foundation.

install in a well-drained area, with the top surface of the platform high enough above grade level to allow installation of a conden-

sate drain trap. See FIGURE4

Converting 230V Units to 208V Toconvert230V unitsto 208V:

1.Turn electric power OFF.

2. Remove the blower/electrical access panel.

3. Locate the 24V control transformer.

4. Remove wire from the terminal labeled "240V" on the 24V control transformer and reconnect it to the 208V terminal of the 24V control

transformer.

5. Replace the electrical/compressor access panel.

Low Voltage Wiring

For access,removethe electricalcontrol/bloweraccesspanel. Refertothe connectionwiringdiagramfortheapplicablemodelandto the instructionsin-

cludedwith the thermostat. Routelow voltagewiresthroughthe portlocatedon the rearpaneland upto thecontrol
