are selected; fan operation of auto (cycling), high and low (constant), auto fan operation automatically selects fan speed according to heating or cooling demand; dry mode operates cooling and electric heat simultaneously to remove humidity, optional electric heat must be selected; test operation allows ease of testing after installation (all timers are eliminated); non-volatile back-up memory, control settings are maintained for an indefi nite period during a power outage, when power is restored the equipment will resume operation after a three-minute compressor time delay; optional hand held infra-red controller. The control voltage between the indoor unit and the outdoor unit shall be 24 Volts A.C. The 24 Volts shall be generated from the indoor unit’s 24 Volt 40VA transformer.
PART SIX “OUTDOOR UNIT”
The outdoor unit shall be completely factory assembled, piped and wired. The cabinet shall be fabricated of G60 galvannealed steel, fi nished in “off-white” with corrosion inhibiting polyester powder-coated paint. The unit shall be furnished with one (1) direct drive, propeller type fan arranged for horizontal discharge. The motor shall have inherent protection, be of the permanently lubricated type, and resiliently mounted for quiet operation. The fan shall be provided with a guard to prevent contact with moving parts. The compressor shall be of the high-performance reciprocating type with an internal thermal overload. The compressor shall be mounted so as to avoid the transmission of vibration. The refrigeration system shall be equipped with high pressure switch and have the capability to operate with a maximum height difference of 35 feet and overall refrigerant tubing length of 100 feet between indoor and outdoor sections without the need for line size changes or additional oil. The condenser coil shall be of nonferrous construction with louvered fi ns bonded to rifl ed copper tubing. The unit shall be controlled by the microprocessor located in the indoor matching unit. The unit electrical power shall be 208/230 Volts, 1 phase, 60 Hertz. The system shall be capable of satisfactory operation within voltage limits of 208/230 Volts +/- 10%. Heating expansion is controlled by a TXV in the outdoor unit.
PART SEVEN “OPTIONAL EQUIPMENT”
•Hand Held Infrared Remote Controller – used to command the unit-mounted controls.
•24V Wall Thermostat Control – anti-short cycle compressor protection; fan purge, fan remains on for 60 seconds after heat/cool call is dropped for improved effi ciency; integral heating relay ensures that the fan operates whenever electric heat is energized; two stage heating capable when matched up with an EMI heat pump and an appropriate two stage thermostat.
•5KW Electric Heat – shall be factory installed; automatic reset high temperature cutout and redundant high temperature fuse link.
•Internal Condensate Pump – shall be fi eld installed or factory installed and shall have 4 ft of head.
•Low Ambient Control – shall consist of a fan cycle switch and a lock-out relay, fi eld installed.
•Hard Start – shall be fi eld installed.
•Sea Coast Style Coated Coils – shall be factory installed; coating shall protect against corrosion due to acids, solvents and salt.
