Chapter 1: Technical Features
I. Technical Features of the 15 and 20kW Single and Three-Phase, Dual-Fuel Generators
This gas generator is Dual-fuel and able to utilize both Natural Gas (NG) and Liquid Propane (LPG).
It is a versatile multi-fuel engine. Based on our standards, we have designed this unit to operate in
an environmentally safe and user friendly manner:
1. Speed Regulating System: This gas generator uses an internally designed electronic speed
control system, allowing for quick and easy adjustments to the engine speed that can be set to
specic speed ranges. This control system allows the engine to run more smoothly and respond
quickly to sudden increases or decreases in required engine speed and electrical output.
2. Silent Air In-take System: Extra-large air intake cross-sections in the housing enclosure ensures
ample air ow for the engine and air intake. This unique housing enclosure design leads to a
signicant reduction in operating noise.
3. Large Liquid Cooled Radiator and Reservoir: The use of an oversized radiator and coolant
reservoir, like those used in automobile engines, allows for additional radiator coil surface and
helps maintain a more ambient and stable engine temperature even in the hottest climates.
Utilizing this liquid cooled system adds to the life and long term operating dependability of your
liquid cooled gas generator investment.
4. Automatic Transfer Switch (ATS) and Function: Our Automatic Transfer Switches are specically
designed to work with our systems and have proprietary connections. The ATS is a critical
component of any emergency or standby power system. They are used for transferring essential
loads and electrical distribution from one power source to another automatically, without
personal involvement.
5. Intelligent Hazard Control System and Function: The Intelligent Hazard Control System warns
of dangerous conditions that exist to the engine or generator. This system continually checks and
monitors the unit’s operating conditions and will automatically shut down if a problem is
detected, to help avoid costly damage. This system uses a visual control panel that can be preset
according to the user’s needs.

running or hot, fuel spills may ignite on contact with hot parts and mufer. Do not operate under the
inuence of drugs and alcohol or smoke. when operating around sparks or open ames. Keep fuel lines
and connections tight and in good working condition.
3. Servicing the exhaust system. Hot parts can cause severe injury. Do not touch hot engine parts. The
engine and exhaust system components become extremely hot during operation.
4. Servicing the engine. Hot parts can cause personal injury or property damage. Keep the generator at
least 2m (6ft) distance from other devices.
5. Grounding electrical equipment. Hazardous voltage can cause severe injury or
death. Electrocution is possible whenever electricity is present. Ensure you comply with
all applicable state and local codes and standards. Electrically ground the generator set,
transfer switch, and related equipment and electrical circuits. Turn off the main circuit
breakers of all power sources before servicing the equipment. Never contact electrical
leads or appliances when standing in water or on wet ground because these conditions
increase the risk of electrocution. It is highly recommended that a barrier exists between
you and the ground surface at all times. We recommend using a wooden pallet with
rubber mat on top to stand on while working or servicing the standby generator.
Grounding is required of all AC circuits, use terminal (identify terminal) for bonding this
circuit to the enclosure with a grounding rod (Not provided with unit). Ground the
enclosure to a grounding electrode in accordance with state and local code
requirements.

Maintenance of the cooling system
When the engine is operating, there must be enough antifreeze and distilled water in the radiator system to
insure proper engine cooling. It is suggested to check it regularly before use, if there is not enough antifreeze
or distilled water add as needed. Do not use mineral, hard water or poor quality antifreeze. We suggest
Prestone, Shell, Texaco or similar brand.
1. Replace antifreeze and distilled water as outlined in the service guide or if discolored to a brown watery mix.
Combine antifreeze and distilled water only to manufactures suggested guidelines.
Do not replace cooling liquid when the engine is hot.
After prolonged use or time, the coolant can go bad and discolor. Follow the recommended steps as outlined
below;
• Place pan under pre-plumed coolant or water line pipe. See photo above.
• Open coolant or water line pipe valve and allow it to drain completely.
• Remove or wipe any old excess water.
• Close coolant or water drain pipe line valve.
• Rell radiator cooling system and reservoir until full.
• Start the generator without load for a few minutes. Allow for air pockets in the system to settle. Shut
down generator and add additional coolant as needed until the level remains steady.
• Shut down generator again and add coolant to the “FULL” level mark
• Make sure the expansion tank is lled half way between low and full mark.
• Install radiator cap and expansion tank cover. Inspect system carefully to make sure there are no leaks.
Hard water, mineral water and saline water is harmful to the engine and cooling system.
Do Not Use!

1. Routine Radiator Maintenance tips
• Regularly check radiator hoses. Inspect clamps and make sure they are secure.
• If hoses become deformed, develop bulges, hardening or cracking is visible, they need to be changed
immediately!
• Inspect and clean the cooling ns on the radiator regularly, use compressed air to blow out excess dust
and dirt. Important! Blow compressed air from the inside out. Debris can build over time and affect the
cooling system.
2. Routine Belt inspection tips
Adjust and replace timing belt and water pump belt as needed. Inspect them regularly for cracking or missing
pieces of rubber. Timing belt needs replacement every 1,000 hours of use! Water pump belt is extremely
important. It drives the water pump that cools the engine and entire system.
Note: Listen for sounds coming from the belts. If you hear the belts squealing when the generator starts
up, this is a sign that the belts are loose or worn and the system will run hot! If belts show signs of cracks
or pieces of belt are missing, contact service provider.
Important! To check to see if the belt is too tight make sure the main power
switch is in the off position.
Perform the following inspections and adjust or replace belt as needed.
Deection check of the belt:
7~10mm (0.28-0.35in) ∕ 100N {10.01kgf (22.1 lbs.)
Adjust the deected belt:
• Stop the engine.
• Use thumb to press on the belt between pulley wheels.
• If the tightness is not correct, adjust it by relaxing the tension wheel to the acceptable degree.
• Replace the water pump belt when it is cracked, missing pieces of rubber or singes of considerable wear.
