CABINET UNIT HEATERSSELECTION AND "ROUGH IN" MADE EASYONLY THE LENGTHS VARYThe Sterling Cabinet Unit Heater is theindustry’s most recent design. Years ofmanufacturing and engineering experience combined with a concern for appearance have resulted in a crisply styledunit that will blend with almost any roomdecor and provide reliability, durability,individual control and quiet operation.As unit size increases, only the lengthchanges. The depth and height remainconstant, thus allowing the designer tohave uniformity of appearance when unitsof various sizes are installed in adjacentareas.The wide selection of floor, wall and ceilingunits with a variety of air flow arrangementsallows for exactly matching design requirements.The standard 16-gauge front panel isrugged enough to withstand harsh treatment. Exposed cabinetry is provided with aneutral eggshell baked powder finish. Backand side panels are 18-gauge.2The pedestal base for floor models is theheight of most mop boards.Field repainting to match the decor ispossible and factory applied decoratorcolors are available as an option.Recessed models are provided with a fieldinstalled wall seal that allows for full orpartial recessing depending on the model.The wall seal kit is also available as anoption for full or partial recessing of mostother models.The solid state speed control providesinfinite variations from high to low speed,giving the occupant finger tip control overfan speed and room temperature.All Sterling commercial hydronic productsare made from recycled materials. Materialrecycled contents can be obtained fromyour local Sterling representative.All units are CSAcertified.

CABINET UNIT HEATERSRATINGS AND SPECIFICATIONSWALL SEAL - The optional wall seal kit with gasket isdesigned to allow for easy installation and permanent protection for the wall board, plaster orsheet rock surrounding the unit on recessed models.COILS STANDARD ONE ROW - The durable mechanicallybonded copper/aluminum coil presents the bestof today’s hydronic technology. Providing 12 fins perinch with 1/2" nominal diameter tubes, the ultimatein BTU capacity is provided without sacrificing noise,vibration or amp draw. All element assemblies aresubmersion tested at factory at 250 PSI and arerated at a working pressure of 300 PSI All units aredesigned so that field modifications can be madeto reverse the coil position if required.HIGH CAPACITY COIL - This is a hot water coildesigned to provide increased capacity whenthe required load exceeds that of the standardcoil for a given size. Its construction is similar to thestandard coil; however, fins are double depth andthere are two rows of tubes. Element assembliesare submersion tested at 250 PSI and are rated at aworking pressure of 300 PSIBLOWER FAN ASSEMBLY - The blower fan assemblyprovides one of the industry’s best CFM output perunit size. The sizes range from 200 CFM up to the1400 CFM unit at 115 volts. This is the widest rangeof sizes in the industry. The Low Noise blower assemblyis made with galvanized steel, providing long lifeand durability.MOTORS - Standard motors are (PSC) permanentsplit capacitor. This provides the ultimate in motorlife, operating cost, noise levels and dependability.A standard shaft size of 1/2" diameter is the same onall motors. By using a solid state variable speedswitch, a range of speeds can be achieved. Motorsare either 1/15 or 1/10 HPECM MOTOR - Optional motors are ElectronicallyCommutated Motors (ECM). These motors arehighly efficient at full and part load with efficienciesup to 85% compared to 40% with traditional PSCmotors. The ECM motors are also 1/15 or 1/10 HP withlow power consumption, providing energy savingswhich will satisfy green building initiatives.FILTER - The standard permanent filter is made ofdurable aluminum which has an average arrestanceof 69%. Light and easy to handle, the filter slides intoits locating channel and is permanently held inposition with factory supplied cotter pins.FRONT PANEL - 16-gauge front panel is standard with1/2" - 1-1/2 lb. density, neoprene one side insulationin front of the coil. Full panel insulation is availableas an option. Tamper resistant fasteners are alsoavailable.MOTOR/BLOWER SHELF - Support shelf adds supportto units strength and structural integrity. A supportgusset is supplied with 600 CFM units and up.FINISH - Standard finish is an aesthetically pleasingneutral eggshell baked powder, which is suitable forfield repainting if necessary. Optional colors available as shown on color chart.LEVELING LEG - Optional leveling legs are available.Four (4) legs per unit allow adjustment for pitch andyaw when unit is mounted on uneven floors.SPEED CONTROL / ACCESS DOOR - The solid statespeed control allows infinite speed selection forcomfort control. Located under the finger touchaccess door, the speed control is out of view yeteasily accessible. The access door requires just thepressure of a finger to open and swings 120 to astay open position. The access door comes with astandard 1/4 turn/philips head fastener and is available with optional tamper resistant fastener. Speedcontrol switch is not mounted on C or RC units.ACCESS AREA - A spacious rough-in area is providedbetween the unit ends and the internal cabinet atboth ends. The removable front panel allows fullaccess to the piping and valve area (left-handstandard) and to the wiring, switch area.Right hand shown. The rear portion is enclosed withsheet metal.HINGED PANEL / CEILING UNIT - The hinged panelson all ceiling units are standard. Stop chains arestandard. Speed control switches are shipped insideunit with wiring diagram. Switch can be mountedinternal or remote from unit.CONSTANT CABINET DIMENSIONS - Throughout thedesign of the cabinet unit heater, one feature hasbeen a primary concern - "uniformity." The cabinetdepth is one dimension on all unit sizes. Along withthat, the cabinet height is constant on all unitsexcept FS and FSI. Only the length changes onthese models. The internal cabinet allows for allcontrols and piping to be reversible by making alllocator and fastener holes in mirror image.SLOPING TOP CABINETS - Best feature for areas thatcannot tolerate accumulations of books, cups,paper, etc.5
