FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE
DESCRIPTION
The HDH Series condensing unit is the outdoor part of a ver-
satile system of air conditioning. It is designed to be custom-
matched with one of York’s complete line of evaporator sec-
tions, each designed to serve a specific function. Matching
Air Handlers are available for upflow, downflow or horizontal
application to provide a complete system. Electric heaters are
available if required. Add-On coils are available for use with
upflow, downflow or horizontal furnaces.
WARRANTY
5-year limited parts warranty.
10-year limited compressor warranty.
FEATURES
• QUALITY CONDENSER COILS - The coil is constructed
of enhanced copper tube and aluminum fins.
• COIL PROTECTION - Coils are protected from damage by
a polymer mesh applied between the coil face, and a PVC
coated steel coil guard.
• PROTECTED COMPRESSOR - The compressor is inter-
nally protected against high pressure and temperature.
This is accomplished by the simultaneous operation of
high pressure relief valve and a temperature sensor which
protects the compressor if undesirable operating condi-
tions occur.
• DURABLE FINISH - Cabinet is made of powder painted
steel over pre-primered steel. The pre-treated galvanized
steel provides a better paint to steel bond, which resists
corrosion and rust creep. Special primer formulas and
automotive quality finish insure less fading when exposed
to sunlight.
• LOWER INSTALLED COST - Installation time and costs
are reduced by easy power and control wiring connec-
tions. Hard start kits are available for non-scroll models. All
units contain enough refrigerant for a matching indoor coil
and 15 feet of interconnecting piping. The small base
dimension means less space is required on the ground or
roof.
• TOP DISCHARGE - The warm air from the top mounted
fan is blown up away from the structure and any landscap-
ing. This allows compact location on multi-unit applica-
tions.
• LOW OPERATING SOUND LEVEL - The upward air flow
carries the normal operating noise up 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.
• LOW MAINTENANCE - Long life permanently lubricated
motor bearings need no annual servicing.
• EASY SERVICE ACCESS - Fully exposed refrigerant con-
nections and a single panel covering the electrical controls
make servicing easy.
• SECURED SERVICE VALVES -Provided on both the liq-
uid and vapor sweat connections for ease of evacuating
and charging.
• U.L. and C.U.L. listed - approved for outdoor application.
Certified in accordance with the Unitary Small Equipment cer-
tification program, which is based on ARI Standard 210/240.
