OVERVIEW
HT40M Water Heater enjoys wide application on various engine coolant pre-
heated. It has fine cast aluminum enclosure and self-extinguishing engineering
plastics end closure, easy and convenient to use.
If during cranking the ambient 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.
Therefore engine heater should be installed to ensure normal starting and
running of the engine when the ambient temperature is lower than 4 ºC.
HT40M 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: 40ºC; 50ºC and 60ºC heaters
are needed to be customized).
This product is suitable for various engines with (13~25) L displacement.
Please login our company’s official website to select heaters.

OPERATION
COMMISSIONING
If heater doesn’t work and overheat indicator doesn’t light up, users can force heater to work by pressing test button.
OVERHEAT PROTECTION RESET
When overheat alarm indicator lights up, 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.
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 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.
Heat resisting power line is strongly recommended.
Earth line must be soundly connected to earth.
Drain valve: Can be opened or closed using hexagonal tools.
