LISTED

This product was manufactured
in a plant whose quality system
is certified/registered as being
in conformity with ISO 9001.

Certification applies only

when the complete

system is listed

with ARI.

DESCRIPTION

These high efficiency EFH Series heat pump units are the out-
door part of a versatile system designed to economically heat
and cool a home or small business. The compact design of these
outdoor units make them ideal for ground or roof installation. The
units contain enough refrigerant charge for the outdoor unit, a
matched indoor coil and 15 feet of interconnecting piping.
EFH heat pumps can be custom-matched with one of YORK's
two lines of evaporator blower sections, each designed to serve
a specific function. Electric heaters are available for both, 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 limited parts warranty.
10-year limited compressor warranty.

FEATURES

•

QUALITY COILS -

The coil is constructed of copper tube and alumi-

num fins.

•

COIL PROTECTION -

Coils are protected from damage by a polymer

mesh applied between the coil face, and a PVC coated steel coil
guard, or a polymer coil guard.

•

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 cov-
ering of the electrical controls. The small base dimension means
smaller mounting pads or less materials required for mounting, lower-
ing installation costs.

•

COMPRESSOR -

2 - 5 ton models are equipped with scroll compres-

sors which are internally protected against high pressure and tempera-
ture. 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. The compressor is
protected by a 10 year limited warranty.

•

COMPLETE SYSTEM CONTROL -

These heat pump units utilize the

unique YorkGuard V microprocessor control system to provide optimal
comfort control and assure reliable operation. The YorkGuard V con-
trol system continuously monitors the space environment to maintain
optimum efficiency. It initiates defrost only when necessary to further
reduce heating costs and improve reliability. Supplemental heat can
only operate below the balance point and then only upon need. In the
event of improper operating conditions (high temperature and high
pressure), the YorkGuard V will shut the system down to extend the
life of the heat pump. Rapid cycling is prevented by use of an integral
anti-recycle timer. Loss of charge protection is provided by a discharge
temperature sensor and internal compressor overloads.

•

Finally the YorkGuard V control provides system diagnostics to aid the
service technician, minimizing repair time and cost. The YorkGuard V
control even stores important information for use during servicing and
has a 5 year warranty.

•

LOW OPERATING SOUND LEVEL -

The discharge air from the top

mounted fan is blown up away from the structure and any landscaping
carrying 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 nor-
mal fan motor and compressor operating sounds.
