FIGURE 1: UNIT CUTAWAY

Electric Heat Operation - All electric heat models (fac- tory installed only) are wired for a single power source and include a bank of nickel chromium elements mounted at the discharge of the supply air blower to pro- vide a high velocity and uniform distribution of air across the heating elements. Every element is fully protected against excessive current and temperature by fuses and two thermal limit switches.

The power supply wiring can be routed into the control box through a threaded pipe connection in the base pan of the unit or through a knockout in the wiring panel on the front of the unit.

BAS Controls - York’s Magnum series units offer factory mounted BAS controls such as Novar, Honeywell, Johnson, and CPC.

FACTORY-INSTALLED OPTIONS

SINGLE INPUT ELECTRONIC ENTHALPY ECONO- MIZERS - Includes a slide-in /plug-in damper assembly with fully modulating spring-return motor actuator capa- ble of introducing up to 100% outdoor air with nominal 1% leakage type dampers.

The enthalpy system contains one sensor that monitors the outdoor air and determines when the air is cool enough and dry enough to provide free cooling.

The rainhood is painted to match the basic unit and must be field-assembled before installing.

Power exhaust is not available as a field installed option.

POWER EXHAUST - Our single economizer options are available with power exhaust. Whenever the outdoor air intake dampers are opened for free cooling, the exhaust fan will be energized to prevent the conditioned space from being over-pressurized during economizer opera- tion.

The exhaust fan, motor and controls are installed and wired at the factory. The rain hood and the back-draft damper need to be assembled and installed in the field.

The power exhaust option can only be used on bot- tom duct configurations.

MOTORIZED OUTDOOR AIR INTAKE DAMPER - Includes a slide-in /plug-in damper assembly with a 2- position, spring return motor actuator which opens to a pre-set position whenever the supply air blower is oper- ating and will drive fully closed when the blower unit shuts down.

The rain hood is painted to match the basic unit and must be field assembled before installing.

PHENOLIC COATED EVAPORATOR AND CON- DENSER COILS - Special coating process that utilizes Technicoat 10-1" processes. Coating is applied by total immersion of the complete coil for maximum protection.

ELECTRIC HEATERS wired for single point power sup- ply. These nickel chromium heater elements are pro- vided with limit and automatic reset capability to prevent operation at excessive temperatures.
