Blade pitch is carefully selectedso that the volume of air moved results in theoptimum discharge air temperature. Pullthroughair fl ow design draws air acrossheating elements for more even air fl ow distributionand cooler element operation.Features• Integral 24V Control Transformer is standardon 480V models and eliminates the need foran external control source( 120V is optional).• Heavy Duty Magnetic Contactors arestandard on all models except 2.6 thru 5 kWsingle phase models, except for 480V models.• Linear Thermal Cutouts open the controlcircuit and disconnect power to the heatingelements if overheating occurs. AutomaticReset allows the control circuit to recloseand restore power when temperature returnsto normal.• Field Convertible — Combination 208/240Vand 1 or 3 phase operation through 10 kW.VERSATILE MOUNTING CONFIGURATIONSVertical DischargeRecessed fasteners on the rear of the heatercabinet are internally threaded for suspensionof unit in the vertical discharge mode withthreaded rods.Horizontal DischargeCeiling Bracket – The ceiling bracket allowsyou mount the heater directly to the ceilingor over-head member, simply and easily. Theswivel mounting allows you to readily adjustthe direction of warm air fl ow for maximumcomfort up to 180˚ rotation.Wall Mounting Bracket – The wall mountingbrackets permits the heater to be rotated toface any direction.Optional Features (Factory Installedor Field Installation Kits)Summer Fan Switch Kit — Field installable forcirculating warm stratifi ed air. Available for allmodels.Thermostat Kit — Field installable on all models.Range 40˚F - 90˚F (55˚F-105˚F thermostatis available).Disconnect Switch — Field installable switchenables power to be disconnected whileservicing heater. 50 Amp rating mounts on thefront of the heaterOutlet Screen — Prevents objects from comingin contact with fanFactory Installed options• Pilot Light (recommended)• Time Delay (heat on and off):Provides delay of fan operation untilelements have warmed up. The fan stayson until cool.Advantages• Self Contained• Versatile, Flexible and High Performance• Easy Installation• Minimum Maintenance• Long Life• Attractive AppearanceBecause it has individually adjustable dischargelouvers to direct air fl ow, and can bewall or ceiling (plus swivel) mounted, the HVHheater may be used in a variety of heatingapplications:• Primary Heating• Supplementary Heating• Dual System Heating• Spot Heating• Entryway Air-Curtain Heating5
