TYPICAL MECHANICAL SPECIFICATIONS
GENERAL
All models are shipped factory pre charged (410A), tested and wired for a single point power connection.
Horizontal (EWH) units are designed for suspended ceiling mounting and are shipped in either right or left
hand configurations refer to dimensional pages for clarification. Vertical (EWV) units are designed for free
standing floor mounting. Water supply, water outlet, and condensate drain connections are via female pipe
thread fittings.
CABINET
All cabinets are constructed of corrosion resistant galvanized steel. Units are complete with integral hanger
holes. The unit is internally insulated with 1/2" thick, 2 lb density neoprene coated insulation. Units are
provided with lift off access panels for ease of servicing while the unit remains in place, and an integral duct
collar is provided on the blower discharge opening. Horizontal units are provide in Left or Right hand return
configurations , ( specify at time of order ) supply discharge may be field converted from end to side . A
flexible duct connection (By others) is recommended.
REFRIGERATION CIRCUITS
All models utilize high efficiency rotary or reciprocating (410A) compressors. Compressors are mounted on
rubber isolators to minimize vibration transmission. Internal overload protection is provided. External high
pressure and low pressure cutout switches are included on each compressor control circuit. Each
refrigeration circuit includes an adjustable bi-flow thermal expansion valve (with external equalizer), bi-flow
liquid line filter drier, and service gauge ports. The reversing valve (on heat pump models) is a pilot operated,
sliding piston type with a replaceable magnetic solenoid coil.
The refrigerant-to-air heat transfer coil is constructed of internally enhanced copper tubes mechanically
bonded to enhanced aluminum plate fins. The evaporator coil is installed in a draw-through configuration for
optimum performance, and the large coil face area minimizes potential water carry over.
The coaxial refrigerant-to-water heat exchanger features a convoluted inner tube design for high heat transfer
efficiency. Standard models feature a copper inner tube surrounded by a steel outer tube, and carry a 400
psig water side working pressure rating.
INDOOR FAN
Forward curved, double inlet and double width, direct-drive centrifugal blowers are used for efficient air
movement. Large diameter wheels have been selected to provide optimum airflow performance at minimum
noise levels. Blower wheels are fabricated of galvanized steel. Fan motors are PSC type, with minimum three
speeds. The PSC motors feature permanently lubricated bearings and internal thermal overload protection.
ELECTRICAL/CONTROLS
All units are completely factory wired with all necessary operating controls. A 24 volt control circuit is provided
for field connection. Units are designed to operate with conventional heat pump thermostat control interface.
The reversing valve solenoid coil shall be energized in the heating mode only.
A manual reset is provided for the compressor control circuit in the event of high/low pressure cutout. A time
delay for anti-short cycle protection is standard in all units. Units include an on board microprocessor control
with diagnostics. Compressor anti short cycle protection is standard.
FILTERS
All models are shipped with 1-inch thick throwaway filters, factory installed. Filters are accessible from
the sides or end of the unit.
STAINLESS STEEL DRAIN PAN
Evaporator drain pan shall be fabricated from 304 stainless steel material. The 3/4 in NPT drain
connection fitting is also from 304 stainless steel
WARRANTY
A parts only warranty is provided with each system for a period of one year from the date of shipment for
vendor verified defective components . Refer to Spinnaker Limited Warranty for all details . An
optional extended compressor warranty is available.
OPTIONAL EXTENDED COMPRESSOR WARRANTY
An optional, four year extended compressor warranty is available at additional cost at the time of original
purchase of the equipment only. This is limited one time replacement only warranty only and obligates
Spinnaker Industries Inc. to replace f.o.b. factory, a defective compressor of equal capacity free of
charge. No responsibility is assumed by Spinnaker Industries Inc. for refrigerant, labor, or freight to and
from the factory.
