OVERVIEW HWP series forced circulation water engine heater is composed of 3 parts (control section, water pump and water heater). If during cranking the outside temperature is lower than 4ºC, engine coolant and lubricant may condense into solid state and lose their lubricating and cooling properties, which can damage the engine. Thus engine heater should be installed to ensure normal starting and running of the engine when the outside temperature is lower than 4 ºC. HWP series forced circulation water engine heater combines the following features: cast stainless steel inner pipes and end closure with high corrosion resistance; heating and overheat light indicators; user-defined thermostat set point; dry heating and overheat protection. This product is suitable for various engine with (15~100) L displacement. Please login our company's official website (www.smartgen.cn) to select heaters. 2. PERFORMANCE AND CHARACTERISTICS -- The circulating water pump adopts special customized pump with stainless steel pump head. -- Control section: microprocessor design; PT100 temperature sampling. Coolant temperature can be set via the control panel. Four digital LED display, current coolant temperature and all kinds of set point temperature can be displayed clearly. -- Dry heating and overheat protection due to the inner overheating temperature detect switch. -- Separately control of water pump and water heater: power on the water pump and water heater synchronously, once the set temperature has reached, water heater will be powered off firstly, after 60s, following is water pump. The goal is to prevent heat concentration and significantly prolong water pump lifetime. -- Manual test: test the water heater and water pump are normal or not via panel button. -- Fine cast aluminum enclosure; -- Stainless steel inner pipes and sealed end closure; -- There is a water drain valve with seal ring on the bottom of the heater so as to be used when needed; -- There is one-way inlet valve on the water inlet. -- This product can work normally at -25 temperature.

HEATER INSTALLATION Please install the heater vertically according to the diagram before use. Pay attention to the direction of heater inlet and outlet, and ensure that the heater position is below the lowest water lever of the engine and that all the air is exhausted out of the heater and it is topped off with coolant. Fig.1 - Installation Plane Schematic Fig.2 Installation Side Schematic HWP Series Forced Circulation Heater Page 6 of 12 Fig. 3 Incorrect Pipe Connection Methods NOTE: If there is a W-shaped bend or reverse U-shaped bend during pipe connection, the air accumulated in the pipe cannot be discharged normally, resulting in the liquid cannot be circulated properly. The air dissolved in the liquid will be precipitated during heating and retained in the bend, so on the condition of unsmoothed pipeline, even if by the manual exhaust, it will repeat in the next heating process of air collection. To ensure that the smooth liquid circulation, the hosepipe with an inner diameter of more than 20mm and pipe joints with an inner diameter of more than 15mm should be selected.

OPERATION DESCRIPTION Fig.5 Operation Panel Drawing Turn Page( ) Using this button you can scroll pages of the LED Nixie Tube and adjust the value. Test( ) If the water temperature has exceeded the preset "ON" temperature, pressing this button will test-run the heater, after 3s, it turns into Auto mode automatically. Lamp Test( ) All indicators will be illuminated when the button is pressed. Set( ) Pressing this button will enter into setting interface, as shown: (Letter "H" means that it is the preset "OFF" temperature, here we take 40 as example)the first digital is flashing and you can adjust it by pressing button. Then press button, the second digital will flash and the HWP Series Forced Circulation Heater Page 8 of 12 adjust way is same as the first digital. Press , as shown: (Letter "L" means that it is the preset "ON" temperature, here we take 25 as example)the first digital is flashing and you can adjust it by pressing button. Then press button, the second digital will flash and the adjusting way is same as the first digital. After doing these, press button, the LED will back the current temperature. All the adjustment should be saved and not lost even when power is off. 6. USE AND MAINTENANCE Before starting the machine, ensure that all the air is exhausted out of the heater and it is topped off with coolant, and make sure that the pump is full of water by using vent valve. Fig.6 Vent Valve Indicating Diagram If water is used, please drain it off when generator is stopped to avoid internal corrosion. Otherwise, the remaining water freezes when temperature is lower than 0°C, which can damage the enclosure. Corresponding antifreeze is strongly recommended. Using tap water or river water will scale the surface of heating pipe and shorten the using life of the heater. Earth line must be soundly connected to earth. Drain valve: Can be opened or closed using hexagonal tools. HWP Series Forced Circulation Heater Page 9 of 12 Fig.7- Water Drain Valve Common Faults and Solutions: 1. Overheat protection: a. Check the valve to assure whether it is opened and whether the heater is full of water; b. Check whether the hosepipe has an obvious W-shaped or reverse U-shaped trend, and whether there is an obvious hot and cold alternating area; Solutions: Shorten the hosepipe length and optimize the hosepipe trend; 2. High water outlet temperature: under normal circumstances, the outlet temperature is about 70. It occurs when the hosepipe is too long, both the inner diameter of the hosepipe and the inner diameter of the fitting joints are too small, as well as the water flow is not smooth so that the heat cannot be transferred properly. Solutions: Shorten the hosepipe length, using the hose with an inner diameter of more than 20mm, and the connectors with an inner diameter of more than 15mm. 3. Unable to reach the preheating temperature: a. The heater power is not enough; b. The cable of the power supply is too long and result in dividing resistance of the cable; Solutions: 1. Replace the heater whose power matches the engine; 2. Shorten the power cable as possible and increase the cable diameter. HWP Series Forced Circulation Heater Page 10 of 12 7.
