OVERVIEW

HWP30N/HWP40N is smart forced circulation water heater of engine. When engine operation temperature is below 4ºC, engine liquid coolant/lubricating oil may be coagulated to solid state in starting phase and lose lubrication or cooling effects, so that it may damage the engine. Therefore, heater shall be installed for engine to ensure normal starting and running. It has lamp indication function, which can indicate all kinds of heater statuses. Heating temperature can be set by users, and dry burning prevention and overheating protection are fitted. This product is suitable for various engines with (15~30)L displacement.

PERFORMANCE AND CHARACTERISTICS

• Micro-processor design is applied for the control part, precise temperature sampling, heating temperature can be set from control panel.
• 4-bit digital tube display is applied, which can display current coolant temperature, user defined temperature, accumulated running time, accumulated energy consumption, current voltage parameters etc.
• Water flow sensor is fitted, which can quickly detect shortage of water, pipe gas gathering, pipe clog, in order to prevent heater from dry burning, gas gathering etc. unhealthy phenomenon.
• Circulation pump and heater are controlled separately; water pump is firstly started before heating, and then heater starts after delay for 5s; when it reaches pre-set temperature point, heater power is disconnected immediately; then water pump power is cut off after delay for 60s; this is to prevent heat gathering so that it can prolong pump life.
• Manual test function is fitted, which can check whether heating body and water pump is able to operate normally through panel button.
• Fine cast aluminum material is used for heater shell.
• Stainless steel inner heating pipes.
• Water drain valve is fitted at the bottom of the heater, which can be used on demand.
• This product can work normally at -40℃ temperature.

OPERATION DESCRIPTION

1. Parameter Check
   Press and to switchover digital cube display and do value adjustment.

2. Commissioning
   If water temperature is above pre-set reset temperature, press ****and heater will enter  commissioning status, and it will transfer to auto status after heating for 10s.

3. Parameter Setting

4. Press and enter parameter setting menu, and it will display (H means the set temperature is cu cut-off temperature value, 40 ºC is only an example example). Press again to enter the setting, and adjust values by and . Press again to move or confirm.

5. Press ****and it will go back to the main menu. It will also return back to first page if there is no operation with in 1 minute.

USE AND MAINTENANCE

1. After it is connected with power, heater is at stop state. Press Auto/Heat and make heater enter working status.
2. When it needs to be checked/fixed or change pipe or some part, press Stop and make heater enter stop status.
3. Before start please confirm whether heater is fully filled with coolant and make gas in the pipe exhausted by vent valve.
4. It is strongly suggested to use antifreezing solution with corresponding mark number.
5. If ordinary water is used, users must drain the water after stop when environment temperature is below 0ºC, in order to prevent the water in the heater getting frozen and resulting in heater fracture.
6. GND wire must be earth connected.
7. Drain valve: Can be opened or closed using hexagonal wrench, adjustable wrench, or a cross screwdriver.
