Thecirculatingblowerandthe condenserfan createanegativepressureon the conden-
satedrain line that will preventthe condensatefromdrainingproperlywithouta trap. To
combatthis negativepressure,afield suppliedcondensatetrapthat willallow a standing

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 electricalwork MUST conformwith therequirementsof localcodesand ordi-
nancesand in the UnitedStates with NationalElectricalCodeANSI/NFPA70-1990 (or
current edition). Provide line voltagepowersupplyfrom a separatefused circuitwitha
disconnectswitch(whenrequired)locatedwithinsight ofthe unit.Supplyvoltage,amper-
age, fuseand disconnectswitchsizes MUST conformwithlocalcodes and ordinances.
Wiring MUSTbe protectedfrompossiblemechanicaldamageand MUST NOT interfere
with removalof access panels,filters, etc.

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 connectionwiringdiagramforthe applicablemodelandto the instructionsin-
cludedwith thethermostat.
Route low voltagewiresthroughthe portlocatedon the rearpaneland upto the control
box.
NOTE:Ifan ElectricHeatAccessoryisinstalled,seethe ElectricHeatAccessoryInstalla-
tion Sectionof thismanualfor lowvoltage connections.
