Amana AGK01 Installation Instruction

3

This unit has many features which are different than those found on conventional PTAC units. The servicer must be familiar with

these features in order to properly service the unit.

• LCDI or AFCI Power Cords - Underwrites Laboratories and the

National Electric Code (NEC) now require power cords that
sense current leakage and can open the electrical circuit to the
unit on units rated at 250 volts or less.  In the event that unit
does not operate, check the reset button located on or near the
head of the power cord as part of the normal troubleshooting
procedure.

• Automatic 3-minute compressor lockout - After the compres-

sor cycles off, it will not restart for three minutes.

• Automatic 2

stage electric heat - If the room temperature

falls to 4°F below the set point temperature, the reverse cycle
heat is shut off and the electric strip heat is turned on.

• Automatic freeze protection - Whenever power is supplied to

the unit and the master switch is in the ON position, automatic
freeze protection is active. If the unit senses temperature below
40°F, the fan motor and electric strip heat are turned on. Freeze
protection can be turned off, if required.

• Random restart delay - To help eliminate power surges after a

power outage, the unit is equipped with a  two to four minute
random restart delay feature.  Whenever the unit is plugged in
with the master switch turned on and the mode switch set in the
cool or heat mode, a random restart will occur.  A random restart
condition can be avoided by setting the mode switch in the fan
only or off position before applying power to the unit.

• Fuse holder - On all 265 volt units, fuse holders are factory in-

stalled.  Check for blown fuse if unit does not operate. Fuse
holder is located behind the front.  Replacement fuses may be
purchased from the Parts Department or contact your sales rep-
resentative for part numbers.

• Indication LEDs - The touch pad has LEDs that corre-

spond to fan operation and to indicate unit status.  The
LEDs next to the selections OFF, COOL, and HEAT in-
dicate which operational mode is active. The LED lo-
cated in the lower left corner is a status LED. This LED
indicates the status of the unit. See Diagnostic Mainte-
nance & Status Report section for further details.

• Load shedding - An LS terminal has been added for

load shedding operations.  If at any time a switch is
closed between the LS and IN terminals, the compres-
sor and electric heater will lockout until the switch is
opened.

• Transfer fan - Terminals TF(-) and TF(+) on the low

voltage terminal board allow for an external (transfer)
fan connection.  A user-supplied relay is required and,
depending upon the type used, an approved external
transformer kit may be required for installation.

NOTE:  The PTAC Wire Harness Kit (PWHK01C) is required
when using either the transfer fan or load shedding option.

• Front mounting hole - A mounting hole is provided to

give the owner the option of securing the front to the
chassis.  The mounting hole is located behind the air
intake grille. The owner must supply one 1/2 inch long
#8 sheet metal screw per unit. The screw must be re-
moved before the front can be removed.
