Product Identification; Design Information - Amana 10c5ez Service

Product Identification

Every Amana Room Air Conditioner has an identification
plate showing the model number, P (manufacturing part)
number, serial number, etc. of unit. Identification plate is
located on front of unit, behind air filter, in lower left
corner. Use plate to positively identify specific model of
unit being serviced.
The following diagram explains how to read Room Air
Conditioner model numbers. Model numbers contain
information about cooling capacity, chassis type, power
requirements, feature set, and design series for unit.

Design Information

Many design features are incorporated into all Amana
Room Air Conditioners. Basic concepts of balance in
refrigeration and air handling components are used in all
models.
The outer case of unit, regardless of style, is designed to
help circulate air across evaporator, condenser,
compressor and fan motor. It must be in place to ensure
maximum efficiency of unit, to prevent overheating of
components, and to maintain the balance and capacity of
the system.
Structural components of room air conditioners are
heavy, zinc-coated steel that is further treated with zinc
phosphate, and electro-coated. Exterior surfaces are
given an additional coat of baked-on polyester.
Acoustical and thermal insulation are used on the
partition panel and in the air discharge plenum to reduce
noise and increase efficiency.
Large evaporator and condenser coils are designed to
provide maximum heat transfer. Coils are manufactured
from rifled copper tubing and rippled edge aluminum fins
to achieve maximum heat transfer. Vibration loops in
refrigeration tubes dampen and isolate system vibrations.

Fan motors are sealed to prevent moisture and dirt
contamination of motor windings. Motor bearings are
permanently lubricated. Large blower wheels and
condenser fans reduce noise levels.
Condenser fans contain an integral slinger ring for
condensate removal. The slinger ring picks-up
condensate and sprays it against the condenser,
increasing condenser evaporative cooling. Alternatively
(in areas of excessive humidity), condensate can drain
from the base pan by puncturing or removing a grommet
in the base pan.
!
CAUTION
To prevent condenser damage, use care when
puncturing or removing base pan grommet. Avoid
using tools long enough to reach the condenser.
NOTE: Drain grommet should only be punctured or
removed in areas of high humidity, when
excessive condensate accumulates in the base
pan. Condensate removal through the slinger
ring increases the cooling capacity of the air
conditioner.
