WALLMASTER® PACKAGED TERMINAL AIR
CONDITIONERS
All units shall be certified in accordance with ARI
Standard 310 for air conditioners and ARI Standard 380 for heat pumps. All units shall be
UL listed.
Basic unit dimensions shall not exceed 42 inches wide and
16 inches high. Overall depth of the unit from the rear of the Friedrich wall sleeve to
the front of the front panel shall not exceed 18-½ inches. If chassis is installed in
non-Friedrich 16" x 42" sleeves, overall depth of the unit from the rear of the
wall sleeve to the front panel shall not exceed 20-½ inches. (NOTE: Deep wall sleeve
extension may add up to 4 inches additional depth on all models installed in Friedrich
sleeves.)
REFRIGERATION SYSTEM - The refrigeration system
shall consist of a hermetically sealed rotary compressor that is externally mounted on
vibration isolators; condenser and evaporator coils constructed of copper tubes and
aluminum plate fins; and capillaries as refrigerant expansion devices. The coils shall be
of a draw-through design to facilitate cleaning. The compressor and fan motor shall be
located in a separate compartment that is isolated from condensate splatter.
AIR HANDLING SECTION - The indoor and outdoor fans
shall consist of tangential blower wheels driven by one permanently lubricated
split-capacitor motor. Air flow shall be directed into the room by a polycarbonate
discharge grille that is factory pro-set to provide maximum air circulation into the room.
The grille shall be owner adjustable to 10 degrees off the vertical. A fine mesh screen
shall be used in the ventilation air stream.
CONTROLS - Covered controls on the top-front of the
unit shall include a push button mode selector switch, rotary thermostat control and a
rocker switch to select the fan speed. The thermostat knob and the push buttons shall not
be removable by the user. The buttons on the switch shall be sized and spaced to prevent
the possibility of depressing two buttons at one time. The control panel shall be easy to
read and understand with the markings for the mode selection no smaller than 14 point
type. International symbols shall be used. A room temperature limiting device,
inaccessible to the user, shall be owner adjustable.
Restricted to the user, but accessible without removing the
front panel, shall be the fan cycle switch, the vent control, and the emergency heat
compressor override switch (on heat pump models). The fan cycle switch shall select
continuous or intermittent fan operation, whereby the blowers cycle with the compressor or
heater.
GENERAL CONSTRUCTION - The wall sleeve shall be
constructed of 18 gauge G90 zinc-coated steel. It shall be prepared by a process where it
is zinc phosphate pretreated and sealed with a chromate rinse, then electrostatically
coated with a polyester finish, and oven cured for durability. It shall be insulated for
thermal efficiency. The sleeve shall be shipped with protective weatherboard and a
structural center support.
The outdoor grille shall be shipped separately. The grille
shall be fabricated from stamped or extruded anodized aluminum. Louvers shall be in a
horizontal pattern.
The front panel shall lock to the chassis, thereby
providing a tamper-resistant design. The front panel shall have a contoured air discharge
with no sharp comers. The air filter shall be a slide-out, top mount design and removable
without opening or removing the front panel.
The unit shall be capable of mounting flush with the carpet
and shall possess a recessed, front return to provide toe-space clearance.
All 265 volt units shall possess an integral over-current
time-delay protective device.
WARRANTY - First year: parts and labor on entire
unit. Second through fifth years: parts and labor on sealed system and Flex-Drive®
system. See Limited Warranty document for complete details. |
