These York® Latitude™ packaged cooling/heating air
conditioners are designed for outdoor installation. Only utility
and duct connections are required at the point of installation.
Field-installed electric heater accessories are available to
provide electric heat, if required. (Single phase only)
Tested in accordance with:
FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
• Operating Efficiency - All cooling units provide a SEER
of 13.0.
All heat pump units provide operating efficiency of 13.0
SEER and 7.7 HSPF. All efficiencies meet legislated
minimum levels.
• Lower Installation Cost - Installation time and costs are
reduced by easy power and control wiring connections.
The small base dimension means less space is required
on the ground or roof, plus, the installer can fit this unit
between the wheel wells of full size pick-up truck. All
models are well under 400 pounds.
All units are completely wired, charged with R-410A and
tested prior to shipment. Unique test stations using a new
state of the art computerized process system are used to
Unitary Products Group3
insure product quality. Refrigerant charge and component
part numbers are verified via computers at assembly. Vital
run test statistics such as system pressure, motor
currents, air velocity and temperature, unit vibration, and
gas system safeties are monitored and recorded by the
system to insure unit performance.
Equal size, side supply and return duct connections
allows easy hook-up of ducts to match low crawl spaces
without transition pieces.
• Coil Technology - All cooling units utilize Micro-Channel
"all-aluminum" condensers which provide improved heat
transfer capabilities, and reduced charge volumes. All
evaporators utilize a conventional copper tube/aluminum
fin design for proven reliability and performance.
• Utility Connections Made Easy - Electric utility
knockouts are provided through the side of the unit. Utility
connections can be made quickly and with a minimum
546039-YTG-C-0211
amount of field labor. A field supplied and field installed
electrical disconnect switch must be installed.
• Round Duct Flanges - (Factory Supplied - Field
Installed) Equal size, side supply and return duct flanges
allow easy hook-up of ducts.
• Condensate Pan - A non-corrosive, long-lasting, watertight pan is positioned below the evaporator coil to collect
and drain all condensate. Less collection of stagnate
condensate will build-up. The condensate pan conforms
to ASHRAE 62-89 standards (Ventilation for Acceptable
Indoor Air Quality).
• Condensate Drain - The 3/4 inch NPTF connection is
rigidly mounted to assure proper fit and leak tight seal.
• Durable Finish - With a heavy duty cabinet made of
powder-painted, galvanized steel the neutral color blends
into surrounding areas. The powdered paint provides a
better paint to steel bond , which resists corrosion and rus t
creep. The glossy finish insures less fading when exposed
to sunlight and offers a more attractive on site
appearance. This paint finish meets ASTM-B117
standards for 1000 hours salt spray rating, the highest in
the industry.
• Full Perimeter Base Rails - The base rails provide a
solid foundation for the entire unit and protects the unit
during shipment. The rails provide fork lift access from all
sides. On applications where the unit is placed on a pad,
the base will keep the unit off the pad to deter corrosion.
• More Attractive Appearance - A single piece Water
Shed top cover containing a top discharge condenser fan
arrangement requires less square footage on installation
and provides a wider variety of installations. The one
piece design adds greater water integrity.
• Top Discharge - The top discharge condenser fan does
not disrupt neighboring areas or dry-out vegetation
surrounding the unit. The warm air from the top mounted
fan is blown up away from the structure and any
landscaping. This allows compact location on multi-unit
applications.
• Condenser Coil Grille - All models utilize a decorati ve
"Wire Form" coil guard to provide impact protection
against large objects.
• Low Operating Sound Level - The upward air flow
carries the normal operating noise up and away from the
living area. The rigid top panel effectively isolates any
motor sound. Isolator mounted compressor and the
rippled fins of the condenser coil muffle the normal fan
motor and compressor operating sounds.
• Fan System - 2, 2-1/2 and 3 Ton A/C models operate with
a 3-speed PSC (Permanent Split Capacitor) fan motor. 4
and 5 Ton A/C and all Heat Pump models operate with a
constant torque (X Motor) fan motor with 5 speed taps. All
these units easily match all types of applications and
provide greater on site flexibility to match comfort
requirements.
• Protected Compressor - The compressor is internally
protected against high pressure and temperature. This is
accomplished by the simultaneous operation of high
pressure relief valve and a temperature sensor which protect
the compressor if undesirable operating conditions occur.
• Pressure Switches - High pressure and low pressure/
loss of charge switches standard in all units. On Heat
Pump models, when abnormal conditions are sensed
through the pressure switches, the unit will lock-out
preventing further operation until reset or the problem is
corrected.
• Exclusive Coil Design - Grooved copper tubes and
enhanced aluminum fin construction on all indoor coils
and heat pump outdoor coils improve heat transfer for
maximum efficiency and durability or Micro-Channel
aluminum tube, aluminum fin on all cooling outdoor coils
for long lasting durability and efficient operation.
Low Maintenance - Long life, permanently lubricated
•
condenser and evaporator fan motor bearings need no
annual maintenance adding greater reliability to the unit.
• Secured Service Access Ports - Protected, externally
mounted, re-usable service access ports are provided on
both the high and low lines for ease of evacuating and
charging the system. No final field mounting required.
• Easy Service Access - A large, single panel covers the
electrical controls makes servicing easy. The blower
compartment has a large panel which when removed will
allow the blower fan assembly to slide-out for ease of
maintenance and trouble shooting.
• Replacement Parts - The installer requires no special
training to replace any of the components of these units
and does not need to maintain an inventory of unique
parts.
Field Installed Accessories
• Wall Thermostat - The units are designed to operate with
24-volt electronic and electro-mechanical thermostats.
• Electric Heat Kit - Available in 4 different kW capacities
(5, 7, 10 and 15 kW). (Single phase only)
• Start Assist Kits - Available for all models.
• Outdoor Thermostat - Available for all heat pump models.
