OVERVIEW

HT Series Water Heater enjoys wide application on various engine coolant preheaters. It has fine cast aluminum enclosure and self-extinguishing engineering plastics end closure, multiple installation ways and easy and convenient use.
If during cranking the outside temperature is lower than 4℃ engine coolant and lubricant may condense into solid state and lose their lubricating and cooling properties, which can damage the engine.
Engine heater should be installed to ensure normal starting and running of the engine when the outside temperature is lower than 4℃.
HT Series Water Heater combines the following features: cast stainless steel inner pipes and end closure with high corrosion resistance; power, heating and overheat protection light indicators; 3 kinds of heaters with different heating temperature are optional (Standard heater: 40℃; 50℃ and 60℃ heaters are needed to be customized).
This product is suitable for various engine with (0~13)L displacement.
Please login our company’s official website (www.smartgen.com.cn) to select heaters.

PERFORMANCE AND CHARACTERISTICS

• Fine cast aluminum enclosure and special surface treatment with high corrosion resistance and high/low temperature capability;

INDICATOR

OPERATION

TEST RUNNING

If the heater is not heating and the overheat protection light is not on, users can press “Test” button to perform the test-run operation.

RESET OVERHEAT PROTECTION

When overheat alarm indicator is on, heater will enter into overheat protection status and stop heating. If heater temperature falls below the reset temperature limit of overheat protection thermostat (95℃), users need to press reset button and heater enters into auto mode again.

WIRE CONNECTION

The supplied power cable is 1.2 m long. Please follow the back cover application diagram when wiring; earth line must be soundly connected to earth.
In the above diagram: L–Phase line (Red), N-Neutral line (Green), E-Earth line (Yellow).

HEATER CONNECTION

Please install the heater vertically according to the diagram before use. Paying attention to 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.

INSTALLATION AND OVERALL DIMENSIONS

CAUTION

Before starting the machine, ensure that all the air is exhausted out of the heater and it is topped off with coolant. If water is used, please drain it off when engine is stopped to avoid internal corrosion.
Otherwise, the remaining water freezes when temperature is lower than 0℃, which can damage the enclosure. Using tap water or river water will scale the surface of heating pipe and shorten the using life of the heater.
Corresponding antifreeze is strongly recommended.
Earth line must be soundly connected to earth.
Drain valve: Can be opened or closed using hexagonal wrench, adjustable wrench, or a crossscrewdriver.

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.
