SmartGen HWP40-3 Forced Circulation Heater User Manual
OVERVIEW
HWP40-3/HWP60-3 forced circulation engine water heater is composed of 3 parts (control section, water pump and water heater).
If the outside temperature is lower than 4ºC, engine coolant and lubricant may condense into solid state and lose their lubricating and cooling properties during cranking, 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 4ºC.
HWP40-3/HWP60-3 forced circulation engine water heater combines the following features: cast stainless steel inner pipes and end closure with high corrosion resistance; heating and overheat light indicators; user-defined coolant set point; dry heating and overheat protection.
This product is suitable for various engine with (15~50)L displacement.
Please login our company’s official website (www.smartgen.com.cn) to select heaters.
PERFORMANCE AND CHARACTERISTICS
- The circulating water pump adopts special customized pump with stainless steel pump head;
- Microprocessor design of control section and 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;
- Manually 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 -40ºC temperature.

OPERATION DESCRIPTION
★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 40ºC 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 adjust way is same as the first digital. Press , as shown: (Letter “L” means that it is the preset “ON” temperature, here we take 25ºC 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.
USE AND MAINTENANCE
VENT VALVE
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.
WATER DRAIN VALVE
If ordinary water is used, please drain it off when temperature is lower than 0ºC for avoiding heater bursting caused by frozen remaining water. Corresponding antifreeze is strongly recommended.
Earth line must be soundly connected to earth. Drain valve: Can be opened or closed using hexagonal tools.
