DESCRIPTION
The EFD Series heat pump is the outdoor part of a versatile sys-
tem designed to economically heat and cool a home or small busi-
ness. The compact design of these outdoor units make them ideal
for ground or roof installation. They are available with sweat con-
nect field piping connections. These units have service valves and
contain enough refrigerant charge for the outdoor unit, a matching
indoor coil and 15 feet of interconnecting piping.
EFD heat pumps may be custom-matched with one of YORK's
indoor line of evaporator blower sections, each designed to serve
a specific function. Electric heaters are available for both single
and three phase applications, in a variety of sizes.
For Add-On applications, the indoor coil may be applied in the
supply duct of a conventional gas, oil or electric furnace. The heat
pump will be the primary source of heat for the building with the
furnace operating only when the heating requirement exceeds the
capacity of the heat pump.
WARRANTY
5-year lim
ited parts warranty.
5-year limited co
mpressor 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.
• DEFROST CONTROL - Time / Temperature defrost control
provides field selectable time periods between defrost cycles
(30, 60 and 90 minutes). LED lockout indicator, anti-short cycle
timer protection are also provided. A built-in soft lockout helps
to avoid nuisance trips on high pressure.
• 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 com-
pressor if undesirable operating conditions occur. All units have
standard crankcase heat for added protection (except 048 and
060, since they are scroll compressors).
• DURABLE FINISH - Cabinet is made of pre-painted steel. The
pre-treated flat galvanized steel provides a better paint to steel
bond, which resists corrosion and rust creep. Special primer
formulas and glossy earth tone finish insure less fading when
exposed to sunlight.
• LOWER INSTALLED COST - Installation time and costs are
reduced by the fully exposed refrigerant connections and the
single panel covering of the electrical controls. The small base
dimension means smaller mounting pads or less materials
required for mounting, thus lowering installation costs.
• TOP DISCHARGE - The air from the top mounted fan is blown
up away from the structure and any landscaping. This allows
space saving arrangements of multi-unit installations.
• LOW OPERATING SOUND LEVEL - The upward air flow car-
ries 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 con-
denser coil muffle the normal fan motor and compressor oper-
ating sounds. A compressor blanket accessory is available for
those applications requiring further sound reduction.
• LOW MAINTENANCE - Long life permanently lubricated
motor- bearings need no annual servicing.
• RE-USABLE SERVICE VALVES - Provided on all sweat fit-
tings on both the liquid and vapor connections for ease of evac-
uating.
• U.L. and C.U.L. listed - approved for outdoor application.
Certified in accordance with the Unitary Small Equipment certifica-
tion program, which is based on ARI Standard 210/240.
