PTAC Installation Recommendations
For proper PTAC unit performance and maximum operating life refer to the minimum installation clearances
below:
Figure 1
PTAC. units. should. be. installed.
no. closer. than. 12". apart. when.
two. units. are. side. by. side.. . If.
three.or.more.PTAC.units.are.to.
operate.next.to.one.another.allow.
a.minimum.of.36".between.units.. .
Also,.a.vertical.clearance.of.60".
should. be. maintained. between.
units. installed.. . In. the. interior.
of. the. room. the. unit. should. be.
located. a. minimum. of. 1/4". from.
the. floor. and. a. minimum. of. 36".
from.the.ceiling.
For PTACs on the ground floor or anytime obstructions are present, use the following guidelines:
Figure 2
For. minor. obstructions.
•
such.as.lamp.poles.or.small.
shrubbery. a. clearance. of.
12".from.the.outdoor.louver.
should.be.maintained.
For.major.obstructions.such.
•
as. a. solid. fence,. wall. or.
other. heat. rejecting. device.
like. a. condensing. unit,. a.
minimum. distance. of. 36".
should.be.kept.
The.above.suggestions.are.for.reference.only.and.do.not.represent.all.possible.installations...Please.contact.Friedrich.for.information.regarding.affects.of.other.
installation.arrangements...By.following.these.simple.recommendations.you.can.be.confident.that.your.Friedrich.PTAC.will.provide.years.of.worry.free.operation.
