HOTSTART Engine Heating P.O. Box 11245 Spokane Valley, WA 99211-0245
All HOTSTART heaters with thermostats, designed to operate on 3-phase current (at any voltage), require the use of a control system with a 3-pole contactor. All Kim Hotstart heaters with thermostat designed to operate over 480 volt (1 phase or 3 phase) require a control system to reduce the primary voltage to 120 volts for the control circuit. For increased thermostat life, use a control system on all heaters above 277 volts either single or three phase. These control systems allow for quick electrical installation of all HOTSTART engine preheaters. They are designed as a time and labor saving component. They are especially useful on installations that require two coolant heaters or combinations of a coolant heater and oil heater/hydraulic heater etc. All control boxes on this and preceding page are NEMA 12 & 13. All control boxes are available for Class 1 Group D hazardous locations. Change prefix JBW to JBE and consult factory for price and availability.

Technical Information & Heater Installation Instructions OPERATING PRINCIPLE

The HOTSTART engine heater operates on the principle of a thermosiphon. As the temperature of the coolant in the heater tank increases, its density decreases causing it to rise through the outlet of the tank to the engine. The coolant leaving the heater tank is replaced with coolant drawn from the engine and the cycle is repeated. A flow-through thermostat is available for the inlet of the engine heater that keeps coolant within the preset temperature range.
CAUTION
Prior to heater installation, check the cooling system. Poor coolant conditions will interfere with proper function of the heater and can also cause element failure. If there is sediment or foreign matter present or the coolant does not meet the engine manufacturers 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 exceed a concentration of more than 60% antifreeze, as element failure may result. A cooling system containing anti-leak additives can cause premature element failure. MOUNTING Mount 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 with the mounting straps provided. See Figure 2. The heater must be mounted below the lowest level of the engine water jacket to ensure a good gravity flow of coolant to the heater.

CAUTION
DO NOT mount the heater to the engine. Engine vibration can damage the heater and void the warranty. Connect the heater intake to the lowest accessible point of the water jacket. If a connection point is unavailable in the water jacket area, connect heater intake line to lower radiator hose. This hose should run down to heater intake. Connect heater outlet to the highest accessible point in the engines water jacket area at the furthest point from the engines thermostat. The heater outlet must be connected at a higher point on the engine than the intake. See Figure 3.

NO Lowest level of water jacket
FIGURE 2

NO
CAUTION
DO 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 the heater. See Figure 3. To eliminate air locks in the heater and hoses, refill the engine with the heater outlet line disconnected at the engine until outlet line is full of coolant. See Figure 4-1. Then connect the outlet line to the engine and finish filling the engine. See Figure 4-2. Before energizing heater, all air must be bled out of the system by running the engine. If not, air could be trapped in the block causing the heater to fail.
FIGURE 3 YES 1 2 NO
NO
CAUTION
The bi-directional ball check valve located in the inlet of the heater allows a reduced amount of coolant to reverse flow through the heater when the engine is running. This will maintain a full coolant level in the tank at all times to protect the element from overheating. This is a safety device only. Kim Hotstart recommends NOT running the engine with the engine heater energized. On standby and automatic start engines, heaters should be de-energized when engine 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 the Kim Hotstart thermostat and are also often 3 Phase. All heaters above 277 Volt should be used in conjunction with a contactor and control transformer. All three phase heaters must be used with a contactor. See pages 37, 38, and 39.
Coolant Flow
FIGURE 4
Note: It is recommended for V engines larger than eight cylinders or over 1000 C.I.D. that 2 heaters of equal wattage be used. One heater installed on each bank of the V . Example: To adequately heat a 1000 cubic inch V engine for ambient temperature above -20F use (2) 2000 watt heaters total 4000 watts. For the most efficient heating of this size engine and electrical savings, see the forced circulatiing heating system on pages 16 & 17.

Heater Installation
Instructions for: In-block direct immersion heaters Please refer to specific instructions that accompany heater.
THREADED PLUG TYPE HEATERS

A. Drain the cooling system. B. Remove the recommended plug. (See instructions with heater) C. Apply teflon tape to pipe threads or grease to O ring. D. Thread heater into engine.
Please follow these steps to ensure proper operation of your Kim Hotstart in-block heater.
1. Align cord with pins on the heater and press the cord into the heater. Place clamp around cord & heater. DO NOT PLUG IN HEATER YET! 2. Route the cord, keeping away from hot or moving surfaces. 3. Re-fill the cooling system. Run engine until engine thermostat opens and continue running for another 20 minutes to eliminate air. 4. Stop engine and let cool. Check for leaks. Check coolant level. 5. Plug heater into power supply and test for proper operation. Block should feel warm near heater.
PLATE TYPE HEATERS

A. Drain the cooling system. B. Remove the recommended plate. (See instructions with heater) C. Clean the gasket area. D. Apply gasket sealant to plate and engine surfaces. E. Insert heater into engine. Tighten bolts.
FREEZE (CORE) PLUG TYPE HEATERS

A. Drain the cooling system. B. Remove the recommended core plug. (See instructions with heater) C. Clean, smooth and dry core plug opening. D. If retaining ring style, apply a light coat of grease to the O ring and core plug opening. If press-in style, apply a light coat of high-temperature, high-strength retaining compound (Loctite 640 recommended). E. Insert heater into engine and position properly. Push the heater into the engine by hand, then tap in using a suitable tool until flange is even with engine block.

Specifying an Engine Pre-Heater
1. Determine the best type of heater to be used for the application. Direct Immersion or Tank Type? Weathertight unit for all indoor or outdoor applications (hospital, communications building, shopping mall, pump station, off-road equipment). Explosion Proof unit for Hazardous Locations (off-shore platform, oil rig, gas compression station). 2. Determine engine size. Cubic inch or litre displacement. 3. Determine wattage required by using this general formula: 3 watts x cubic inch displacement = watts required. Example: Engine is 855 C.I.D. 855 x 3 = 2565. Requirement is 2500 watt heater. This formula is a very good rule of thumb to use down to 0F ambient temperature. This formula will generally hold engine temperature at approximately 100F above ambient. Very large engines may require a forced circulation system (see pages 16, 17 and 59). 4. Now that you have the required wattage, you need to determine: Voltage available that will power the heater (120, 208, 277, 240, 380, 480). Is the power source Single Phase or Three Phase? 5. For thermostat selection, determine the desired engine temperature to be maintained. 100F to 120F applies 95% of the time. However, specifications vary with respect to the user and a higher or lower range may be required. You now have the specifications needed to select the required engine pre-heater from the many products listed in this catalog. For other technical information and installation tips, see pages 40 and 55. If you have other questions or need additional assistance, please contact our customer service department.
