2. Safe Installation Requirem ents

CAUTION

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

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.

3. Locatinq & Installinq The Unit

The unitis designedfor outdoorinstallationonly.Placetheunit ona platformat ground
level. The unitmay be installedon a concreteslab of 48" (1219mm)x 48" (1219mm)
dimensions. Cement blocks on a 3" sand footing willalso work. The slab or blocks

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

Installation

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 away 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

Installing Duct Collars
Ductcollarsaresuppliedwiththe unitand 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.

4. Electrical Wirinq

Electrical shock hazard.

Disconnect power at fuse box or service panel before making
any electrical connections.

Unit MUST be grounded to electrical service panel.

Failure to follow this warning can result in property damage,
personal injury, and/or death.

NOTE:All electricalworkMUST conformwiththerequirementsof localcodesandordi-
nancesand in the UnitedStates with NationalElectricalCodeANSI/NFPA70-1990 (or

currentedition). Provide linevoltagepowersupplyfrom aseparatefused circuitwitha
disconnectswitch(whenrequired)locatedwithinsight ofthe unit.Supplyvoltage,amper-

age,fuseanddisconnectswitchsizesMUST conformwithlocalcodes and ordinances.

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.
