All HOTSTART heaters with thermostats, designed to operate on 3-phase current (at anyvoltage), require the use of a control system with a 3-pole contactor. All Kim Hotstartheaters with thermostat designed to operate over 480 volt (1 phase or 3 phase) require acontrol system to reduce the primary voltage to 120 volts for the control circuit. Forincreased thermostat life, use a control system on all heaters above 277 volts either singleor three phase.These control systems allow for quick electrical installation of all HOTSTART enginepreheaters. They are designed as a time and labor saving component. They are especiallyuseful on installations that require two coolant heaters or combinations of a coolantheater and oil heater/hydraulic heater etc.TypicalControl BoxSystemComponentsAll control boxes on this and preceding page are NEMA 12 & 13.All control boxes are available for Class 1 Group D hazardous locations.

Technical Information & Heater Installation InstructionsOPERATING PRINCIPLEThe HOTSTART engine heater operates on the principle of a thermosiphon. As the temperature of the coolant in the heatertank increases, it’s density decreases causing it to rise through the outlet of the tank to the engine. The coolant leaving theheater tank is replaced with coolant drawn from the engine and the cycle is repeated. A flow-through thermostat is availablefor the inlet of the engine heater that keeps coolant within the preset temperature range.CAUTIONPrior to heater installation, check the cooling system. Poor coolant conditionswill interfere with proper function of the heater and can also cause elementfailure. If there is sediment or foreign matter present or the coolant does notmeet the engine manufacturer’s specifications, the system should be drained,cleaned, flushed and refilled with a 50/50 mixture of low silicate antifreeze,deionized water, and low silicate supplemental coolant additives. Do not exceeda concentration of more than 60% antifreeze, as element failure may result. Acooling system containing anti-leak additives can cause premature elementfailure.MOUNTINGMount the tank heater in a horizontal position with the outlet neck pointed up.The heater can also be mounted vertically with the inlet neck as the low point(see figure 1).Bolt the heater to the truck frame or skid frame on a generator package withthe mounting straps provided. See Figure 2. The heater must be mounted belowthe lowest level of the engine water jacket to ensure a good gravity flow ofcoolant to the heater.Outlet NeckOutlet NeckInletInletVERTICAL MOUNTHORIZONTAL MOUNTFIGURE 1CAUTIONYESDO NOT mount the heater to the engine. Engine vibration can damage theheater and void the warranty.Connect the heater intake to the lowest accessible point of the water jacket. If aconnection point is unavailable in the water jacket area, connect heater intakeline to lower radiator hose. This hose should run down to heater intake.Connect heater outlet to the highest accessible point in the engine’s waterjacket area at the furthest point from the engine’s thermostat. The heater outletmust be connected at a higher point on the engine than the intake. See Figure3.NOLowest level of water jacketFIGURE 2YESNOCAUTIONDO NOT route outlet hose above engine block connection, or loop or kink hoses.This will cause air locks in the hose and block circulation of the coolant by theheater. See Figure 3.To eliminate air locks in the heater and hoses, refill the engine with the heateroutlet line disconnected at the engine until outlet line is full of coolant. SeeFigure 4-1. Then connect the outlet line to the engine and finish filling theengine. See Figure 4-2.Before energizing heater, all air must be bled out of the system by running theengine. If not, air could be trapped in the block causing the heater to fail.FIGURE 3YES1NO2NOCAUTIONThe bi-directional ball check valve located in the inlet of the heater allows areduced amount of coolant to reverse flow through the heater when the engineis running. This will maintain a full coolant level in the tank at all times toprotect the element from overheating. This is a safety device only. Kim Hotstartrecommends NOT running the engine with the engine heater energized.On standby and automatic start engines, heaters should be de-energized whenengine starts. This requires an oil pressure switch or other automatic cut-off.These systems are often operated at voltages above the 277 Volt rating of theKim Hotstart thermostat and are also often 3 Phase. All heaters above 277 Voltshould be used in conjunction with a contactor and control transformer. Allthree phase heaters must be used with a contactor. See pages 37, 38, and 39.40HOTSTART Engine HeatingFIGURE 4Coolant FlowNote: It is recommended for “V” engines larger than eight cylinders or over 1000C.I.D. that 2 heaters of equal wattage be used. One heater installed on each bankof the “V”.Example: To adequately heat a 1000 cubic inch “V” engine for ambient temperatureabove -20 F use (2) 2000 watt heaters — total 4000 watts.For the most efficient heating of this size engine and electrical savings, see theforced circulatiing heating system on pages 16 & 17.P.O.
