13CONDENSATE MANAGEMENT SYSTEMISC accomplishes condensate removal from our air conditioners by routing the refrigerant hot gasthrough a condensate boil off pan. The pan is located ahead of the condenser at the hottest point in therefrigerant system where the gas temperature is 180 to 260 F.Condensate is evaporated and the vapor is discharged through the condenser blower to theenvironment. Additionally, this condensate evaporation helps to pre-cool the hot gas, making theequipment more efficient. By utilizing this pre-cool method, we lower the overall use ofenergy needed to power our air conditioners.This condensate boil off pan has enough water storage capacity to dehydrate the air in your equipmentenclosure and vent it off without overflow so long as the enclosure remains closed.In the event that the enclosure will remain open, ISC does supply an Emergency Overflow Fitting on allof our units. Use of this Fitting is only for extreme open-door applications and should not be utilized intypical or even heavy applications. Please Contact ISC for instructions on use of this feature.4421 Tradition Trail Plano, Texas 75093 972-964-2700 or 800-836-7472 Fax 972-964-2755Web: www.iscenclosurecooling.com Email: iscinfo@iscsales.com

14ENCLOSURE HEAT SYSTEMThe ISC Enclosure Heat System is incorporated into the evaporator section of the air conditioner,thereby utilizing the evaporator blower for cooling or heating. Electric heating elements with thermaloverloads are available in three ranges to suit most applications. The heater is controlled by ourprogrammable, digital temperature controller. The controller has separate programmable upper andlower control limits for cooling and heating, and a programmable dead band to prevent simultaneousoperation of heating and cooling. The temperature set points for cooling and heating can be fieldadjusted in one-degree increments. The temperature set points can be protected by keypad protection.Specifications:Voltage120 - 208/230Watts500, 1000, 1500, 2500Capacity, BTUH1707 / 3413 / 5120 / 8530Temperature Range-99 to 302 degrees FDead band1 to 20 degrees FAccuracyBetter than .5% of scaleResolution.1 degreeCode Protection4 digit, customer settable on request4421 Tradition Trail Plano, Texas 75093 972-964-2700 or 800-836-7472 Fax 972-964-2755www.iscenclosurecooling.com Email: iscinfo@iscsales.com

15OD Remote Controller OptionWhen having our Programmable Digital Controller on the face of our EnclosureAir Conditioner does not fit your application, ISC offers the OD package.The OD package moves the controller into your enclosure using a 10’ cable alongwith a universal, 16 gauge powder coated steel mounting bracket. As shownbelow, the Enclosure Air Conditioner would have no hole on the face of the unitcreating a secure application of our Enclosure Air Conditioner.This accessory is available on all units including NEMA Type 12, 4 and 4X (304Stainless Steel)Having a smarter air conditioner is a good choice even when having an exposedDigital Controller may not be the best choice.Pictured is our NEMA Type 4XAir Conditioner with OD Seriesremote controller option.Information Subject to change without notice4421 Tradition Trail Plano, Texas 75093 972-964-2700 or 800-836-7472 Fax 972-964-2755Web: www.iscenclosurecooling.com Email: iscinfo@iscsales.com

162” DEEP EXTENDED SURFACE AREAFILTER AND FILTER FRAMEMany applications and environments are excessively dusty. If your application is in a flour mill,cement plant or coal processing plant, you understand. These types of environments can create realproblems for an air conditioner that by its very design requires a steady flow of reasonably clean air inorder to function. The reality is that air conditioners are only as good as their air flow.Because of this, ISC offers our extended surface, 2” deep filter and filter frame assembly. Picturedbelow, this slide in, slide out filter frame and filter combination will increase the filter capacity 400%over our standard filters.The filter is washable and replaceable. The life expectancy is determined by the environment and theways in which it is washed and cleaned.This deeper filter frame fits in the standard holes on our NE Series units.Information Subject to change without notice4421 Tradition Trail Plano, Texas 75093 972-964-2700 or 800-836-7472 Fax 972-964-2755Web: www.iscenclosurecooling.com Email: iscinfo@iscsales.com

17CONTROL SYSTEM FOR REDUNDANCY & LEAD/LAGIn applications where you require redundant systems to share the cooling requirements, ISC hasdeveloped a system that will toggle back and forth between the two units thereby giving themeach equal operating time.Additionally, this system provides for the situation where one unit becomes disabled. In thisevent, the second unit continues to provide the appropriate amount of cooling to your electricalenclosure while the disabled unit would be in alarm mode.This system is intended for 100% redundancy where failure is not an option.This is our alternating, or toggle system.ALTERNATING CONTROLThis control method is intended to provide cooling to a common enclosure by two (or more) airconditioners which alternate operation rather than share load. This provides 100% redundancywhile balancing the run time on each unit.Two self contained air conditioners with independent dual stage thermostats will be connectedwith a toggle control so that the units will alternately share the cooling load. In the event of thefailure of one unit, the toggle system will be deactivated and the cooling load will be switchedto the remaining operational unit. A failure signal will be available to alert the customer that oneunit has failed.HIGH LIMITEach Thermostat has a high set point which is used as a failure alarm. On either high limit, thatunit is switched out of the toggle control and cooling will be solely by the alternate airconditioner until the limit is manually reset.4421 Tradition Trail Plano, Texas 75093 972-964-2700 or 800-836-7472 Fax 972-964-2755Web: www.iscenclosurecooling.com Email: iscinfo@iscsales.com

18What Makes Our Panel Air Conditioner Unique?AIR FLOW Note the tapered sides of our air conditioner, our design ensures efficient airflow to cool the airconditioner in a tight installation (vs. a box shape air conditioner). We have a slanted top. This forces any water on the top of the unit to drain, thus prevents water pooling.DIGITAL TEMPERATURE CONTROLLER Our digital controller incorporates programmable set point and temperature controls, visible error and oralarm messaging, system status indication and password protection. Remote control is available with ourOut Door series. These vandal resistant units provide a 10’ cord that connects internally to your enclosure.ACTIVE CONDENSATE ELIMINATION Our design eliminates drain lines and buckets by routing the refrigerant hot gas lines through acondensate boil off pan. This also eliminates the hazards that go along with the puddles and bucketsassociated with drains.UNIT EFFICIENCY By pre-cooling the refrigerant in the condensate collection pan before it re-enters the refrigeration loop,we lower the energy needed to affect a phase change of the refrigerant. Also, by blowing the vaporladen air through the coil to the outside environment, we equalize the temperature across the coil,lowering energy consumption. This efficiency is evidenced by our lower running amps. Pressure operated blower control reduces power inrush thus consumes less energy. All units incorporate die-cut insulation on all interior sheet metal parts including the shroud (cabinet). Thermal expansion valves are installed in all of our air conditioners instead of capillary tubes. Thermalexpansion valves adjust to your operating conditions allowing for much better temperature control,performance and provide lower operating costs. Compressor run capacitors reduce power inrush each time the compressor comes on, saving energy andextending the life of the compressor.HIGH PRESSURE SHUT DOWN Part of our digital controller safety function is to go into alarm if the filter media becomes clogged. Othermanufacturers who utilize digital controllers have an alarm interval based on the time between filtercleanings. By using high and low pressure switches, we insure that you are notified before you have acostly failure.CONSTRUCTION
