Suburban Dynaline 3 A&E Manual 12/2021 Rev.2
9
The supplier will provide packaged terminal gas heat/electric air
conditioner of the sizes and capacities shown on the schedule and listed
in the specifications. Each unit shall consist of a chassis, wall case/sleeve,
outside grille and room cabinet. Units shall be UL listed and/or
ETL design certified and shall be Suburban Manufacturing Company
DYNALINE
™
3 models, or equivalents. The units shall be located as shown on
the drawings.
Unit’s steady state efficiency shall be rated at 80% nominal and the EER
of the air conditioner shall not be less than ASHRAE 90.1 - 2010 standards.
Units shall be designed to operate on 208/230 volts, 60 Hz, single
phase power.
Unit dimensions shall not exceed 42" wide and 16" high without optional air
discharge package in place, and not more than 22-29/32" from face of room
cabinet to face of standard exterior grille.
Units shall be designed to operate on Natural or LP gas for the heating cycle.
CHASSIS:
Unit chassis shall be a standard product of the manufacturer and shall
be packed to prevent damages when reasonable care is exercised during
shipment. Warnings on packaging shall alert handlers to the hazards of
improper handling or stacking.
Chassis shall slide into a standard-sized wall case and, after installation
and testing, be ready to operate. Each chassis shall consist of the following
system and components:
• Refrigeration system constructed to isolate the hermetically sealed
rotary-type compressor from external vibration. The system shall
include copper/aluminum condenser and evaporator coils with
capillary refrigerant control.
• Air flow system consists of a two-speed room air motor (for Hi &
Low A/C and Hi & Low heat speeds) and a fan cycle switch to permit
continuous indoor fan operation. A separate condenser fan operates in
the A/C cycle only. The condenser fan, not operating in the heating
mode, eliminates the potential for exhaust gases to be drawn back and
freezing in the chassis compartment. The room air system incorporates
a tangential blower wheel for reduced noise and increased efficiency.
• Condenser coils, with not less than 13 fins per inch, and evaporator
coils, with not less than 11 fins per inch. Coils shall be constructed
of copper/aluminum and fins shall be bonded to tubes to prevent
electrolytic action.
• Indoor and outdoor airflow which match the coil capacity for efficient
transfer of heat. Design of the unit shall prevent water blow-off on the
indoor evaporator coil. Indoor supply air grille, constructed of extruded
aluminum, shall discharge air at 52 degrees off vertical pattern.
• Electrostatic return air filter, constructed of washable media, that installs
and removes without tools.
• Factory-installed, gas-fired heat exchanger with electronic controlled,
pilotless ignition system and a “draw-through” negative draft
combustion air system. Gas ignition shall occur by energizing hot
surface ignitor, which lights the burner on each thermostatically
controlled heating cycle. Heat exchanger shall be located in indoor
air stream so as not to be visible or accessible through indoor supply
air
grille.
