1. Carefully.read.and.follow.the.installation.instructions.  
2. Make.sure.the.unit.is.the.right.capacity.for.the.area.being.cooled..  
An.undersized.unit.makes.the.unit.work.too.hard,.using.more.  
electricity.than.needed.and.increases.wear...An.oversized.unit.  
will.cycle.on.and.off.too.rapidly,.and.therefore.cannot.control.  
humidity.as.well.  
It is the installer’s responsibility to properly  
apply and install the equipment. Installation  
must be in conformance with the NFPA 70  
-2008 National Electric Code or current edition,

edition and any other applicable local or  
national codes.  
3. Clean.the.filter.frequently.(See.Routine.Maintenance,.Page.27).  
4. Do.not.block.the.air.flow.to.and.from.the.unit.  
5. A.dirty.lter.or.improperly.set.controls.can.affect.the.cooling.  
ability.of.the.unit.  
Failure to do so can result in property damage,  
personal injury or death.  
6. If.cooling.is.weak.and.you.have.verified.that.the.filter.is.clean.

Friedrich PTAC Digital Control and Unit Features  
The.new.Friedrich.digital.PTAC.has.state.of.the.art.features.to.improve.guest.comfort,.indoor.air.quality.and.conserve.energy...Through.the.use.of.specifically.  
designed.control.software.for.the.PTAC.industry.Friedrich.has.accomplished.what.other.Manufacturer’s.have.only.attempted.–.a.quiet,.dependable,.affordable.  
and.easy.to.use.PTAC.  
Below.is.a.list.of.standard.features.on.every.Friedrich.PTAC.and.their.benefit.to.the.owner.  
By.digitally.monitoring.desired.room.temperature.the.room.is.controlled.more.precisely.than.conventional.systems...  
The.large,.easy.to.read.LED.display.can.show.either.set-point.or.actual.room.temperature.as.selected.by.owner.  
Digital Temperature  
Readout  
When.the.unit.is.powered.off.the.unit.can.be.returned.directly.to.heating.or.cooling.mode.by.pressing.the.‘Heat’.or.  
‘Cool’.buttons.without.the.confusing.power.up.sequence.of.some.controls...One-touch.control.takes.guesswork.out.  
of.unit.control.delivering.a.more.enjoyable.experience.and.eliminating.front-desk.calls.  
One-Touch.Operation  
Three.Fan.Speeds  
The.Friedrich.PTAC/PTHP.units.feature.three.fan.speeds.for.the.user.to.select.from...This.allows.the.user.to.  
properly.match.the.amount.of.airflow.for.their.comfort.level.and.also.deliver's.quiet.performance.  
By.having.separate.control.buttons.and.indicators.for.both.fan.and.mode.settings.the.Friedrich.digital.control.  
eliminates.the.confusion.of.previous.digital.PTACs...The.accurate.temperature.setting.provides.greater.guest.  
comfort.than.other.systems.  
Individual.Mode.and  
Fan.Control.Buttons  
The.fan.start.and.stop.delays.prevent.abrupt.changes.in.room.acoustics.due.to.the.compressor.energizing.or.  
stopping.immediately...Upon.call.for.cooling.or.heating.the.unit.fan.will.run.for.five.seconds.prior.to.energizing.the.  
compressor...Also,.the.fan.off.delay.allows.for.“free.cooling”.by.utilizing.the.already.cool.indoor.coil.to.its.maximum.  
capacity.by.running.for.30.seconds.after.the.compressor.  
Quiet.Start/Stop  
Fan.Delay  
When.connected.to.a.wall.thermostat.the.user.can.select.from.high.or.low.fan.speed.at.the.thermostat,.unlike.  
competitive.models.that.have.only.one.speed.selection...This.allow.more.comfortable.and.quieter.operation...  
Requires.the.use.of.Friedrich.remote.thermostat.RT6.or.equivalent.thermostat.with.two.speed.fan.output.  
Two-Speed.Wall.  
Thermostat.Mode  
Some.applications.require.the.use.of.a.wall.mounted.thermostat...All.new.Friedrich.PTACs.may.be.switched.from.  
unit.control.to.remote.thermostat.control.easily.without.the.need.to.order.a.special.model.or.accessory.kit.  
Remote.Thermostat  
Operation  
The.Friedrich.digital.PTAC.features.a.self.diagnostic.program.that.can.alert.maintenance.to.component.failures.  
or.operating.problems...The.internal.diagnostic.program.saves.properties.valuable.time.when.diagnosing.running.  
problems.  
Internal.Diagnostic  
Program  
The.self.diagnosis.program.will.also.store.error.codes.in.memory.if.certain.conditions.occur.and.correct.  
themselves.such.as.extreme.high.or.low.operating.conditions.or.activation.of.the.room.freeze.protection.feature...  
Storing.error.codes.can.help.properties.determine.if.the.unit.faced.obscure.conditions.or.if.an.error.occurred.and.  
corrected.itself.  
Service.Error.Code  
Storage  
By.limiting.the.operating.range.the.property.can.save.energy.by.eliminating.“max.cool”.or.“max.heat”.situations.  
common.with.older.uncontrolled.systems...The.new.electronic.control.allows.owners.to.set.operating.ranges.for.  
both.heating.and.cooling.independently.of.one.another.  
Electronic  
Temperature.Limiting  
When.the.PTAC.senses.that.the.indoor.room.temperature.has.fallen.to.40°.F.the.unit.will.cycle.on.high.fan.and.  
the.electric.strip.heat.to.raise.the.room.temperature.to.46°.F.then.cycle.off.again...This.feature.works.regardless.  
of.the.mode.selected.and.can.be.turned.off...The.control.will.also.store.the.Room.Freeze.cycle.in.the.service.code.  
memory.for.retrieval.at.a.later.date...This.feature.ensures.that.unoccupied.rooms.do.not.reach.freezing.levels.  
where.damage.can.occur.to.plumbing.and.fixtures.  
Room.Freeze  
Protection  
Multiple.compressors.starting.at.once.can.often.cause.electrical.overloads.and.premature.unit.failure...The.random.  
restart.delay.eliminates.multiple.units.from.starting.at.once.following.a.power.outage.or.initial.power.up...The.  
compressor.delay.will.range.from.180.to.240.seconds.  
Random.Compressor  
Restart  
The.Friedrich.PTAC.uses.a.digital.thermostat.to.accurately.monitor.the.outdoor.coil.conditions.to.allow.the.heat.  
pump.to.run.whenever.conditions.are.correct...Running.the.PTAC.in.heat.pump.mode.saves.energy.and.reduces.  
operating.costs...The.digital.thermostat.allows.maximization.of.heat.pump.run.time.  
Digital.Defrost  
Thermostat  
20  
 
Heat.pump.models.will.automatically.run.the.electric.heater.to.quickly.bring.the.room.up.to.temperature.when.initially.  
energized,.then.return.to.heat.pump.mode...This.ensures.that.the.room.is.brought.up.to.temperature.quickly.without.the.  
usual.delay.associated.with.heat.pump.units.  
Instant.Heat  
Heat.Pump.Mode  
The.digital.control.monitors.indoor.conditions.to.ensure.that.the.room.temperature.is.within.five.degrees.of.the.setpoint...  
If.necessary.the.unit.will.cycle.the.electric.heat.to.maintain.the.temperature...This.feature.ensures.guest.comfort.by.  
delivering.the.heating.benefits.of.an.electric.heater.while.maintaining.the.efficiency.benefits.of.a.heat.pump.  
Even.Heat  
Monitoring  
The.owner.may.choose.between.fan.cycling.or.fan.continuous.mode.based.on.property.preference...(Note:.Even.heat.  
monitoring.and.quiet.start/stop.fan.delay.only.operate.in.fan.cycle.mode).Fan.continuous.mode.is.used.to.keep.constant.  
airflow.circulation.in.the.room.during.all.times.the.unit.is.‘ON’...Fan.cycle.will.conserve.energy.by.only.operating.the.  
fan.while.the.compressor.or.electric.heater.is.operating...The.ability.to.set.the.fan.cycling.condition.independently.  
between.heating.and.cooling.mode.will.increase.user.comfort.by.allowing.the.choice.of.only.constantly.circulating.  
air.in.the.summer.or.winter.time...Unlike.other.PTAC.brands.that.only.allow.one.selection.  
Separate.Heat/Cool..  
Fan.Cycle.Control  
In.the.event.of.a.compressor.failure.in.heat.pump.mode.the.compressor.may.be.locked.out.to.provide.heat.through.the.  
resistance.heater...This.feature.ensures.that.even.in.the.unlikely.event.of.a.compressor.failure.the.room.temperature.can.  
be.maintained.until.the.compressor.can.be.serviced.  
Emergency.Heat  
Override  
All.Friedrich.digital.PTACs.have.low.voltage.terminals.ready.to.connect.a.desk.control.energy.management.system...  
Controlling.the.unit.from.a.remote.location.like.the.front.desk.can.reduce.energy.usage.and.requires.no.additional.  
accessories.on.the.PTAC.unit.  
Desk.Control  
Ready

The outside temperature is below  
60º F.  
Do not try to operate your air conditioner in  
the cooling in the cooling mode when the  
outside temperature is below 60º F. The unit  
will not cool properly, and the unit may be  
damaged.  
The digital control is set to fan cycling  
mode.  
Since the fan does not circulate the room  
air continuously at this setting, the room air  
does not mix as well and hot (or cold) spots  
may result. Using the continuous fan setting  
is recommended to obtain optimum comfort  
levels.  
The air conditioner has insufficient  
cooling capacity to match the heat  
gain of the room.  
Check the cooling capacity of your unit to en-  
sure it is properly sized for the room in which  
it is installed. Room air conditioners are not  
designed to cool multiple rooms.

COMPLAINT  
CAUSE  
SOLUTION  
Unit.does.not.cool/heat.room.sufficiently,.or.cycles.  
on.and.off.too.frequently  
The air conditioner has insufficient  
heating capacity to match the heat  
loss of the room.  
Check the heating capacity of your unit. Air  
conditioners are sized to meet the cooling  
load and heater size is then selected to meet  
the heating load. In extreme, northern cli-  
mates, room air conditioners may not be able  
to be used as a primary source of heat.  
This may be due to an excessive heat  
load in the room.  
If there are heat product appliances in use in  
the room, or if the room is heavily occupied,  
the unit will need to run loner to remove the  
additional heat.  
Be sure to use exhaust vent fans while cook-  
ing or bathing and, if possible, try not to use  
heat producing appliances during the hottest  
part of the day. It may also be due to an  
improperly sized unit.  
Depending upon the size of the room being  
cooled, a higher capacity air conditioner may  
be necessary  
This may be normal for higher ef-  
ficiency (EER) air conditioners.  
The use of higher efficiency components in  
your new air conditioner may result in the unit  
running longer than you feel it should . This  
may be more apparent, if it replaced an older,  
less efficient, model. The actual energy us-  
age, however, will be significantly less when  
compared to older models.  
Unit.runs.too.much  
Likewise, you may notice that the discharge  
air temperature of your new air conditioner  
may not seem as cold as you may be ac-  
customed to from older units. This does not,  
however, indicate a reduction in the cooling  
capacity of the unit  
The energy efficiency ratio (EER) and cooling  
rating (Btu/h) listed on the unit's rating plate  
are both agency certified.
