Exhaust gases contain carbon monoxide (CO), an odorless colorless gas. Carbon monoxide poisoning can cause unconsciousness and death. Symptoms of carbon monoxide poisoning include: dizziness, muscular twitching, weakness, sleepiness, throbbing in the temples, headache, inability to think clearly, nausea and vomiting. If you or anyone experiences any of these symptoms move quickly to clean air outside of the RV. -

Page 20: Altitude Adjustment
Fig. 4 When a large motor or air-conditioning unit is started, the generator may shut down due to overload even though the running power of the air-conditioning unit is less than the rated power of the generator. This is due to the instantaneous amperage draw of the air-conditioning unit and is a short duration. If the generator does shut down, allow 5 minutes to elapse before attempting to reconnect the generator to any loads or the RV fuse panel. -
Page 21: Operating In Cold Weather
Fig. 6 Operating the generator at low altitudes with a high altitude setting can cause power loss, poor starting, overheating and engine damage. Always reset the high altitude adjustment when returning to lower altitudes. Operating in Cold Weather Pay particular attention to the following when operating the generator in cold weather. 1. -

effective for generators with a bottom air inlet that is ducted to the side of the coach. These vents consist of a cutout in the door of the generator compartment to allow airflow through it into the inlet of the generator. There are many design considerations that must be taken into account with a generator installation utilizing a door vent. -
Page 24: Operating The Generator In A Motorized Rv When Not Moving
1. Pay attention to the generator airflow direction, and avoid impeding it – airflow can be greatly hindered by curbs and hills. Watch how close the generator is to the ground, and avoid placing camping equipment such as coolers or chairs under the generator. 2. -

and is not an immediate cause for concern. The generator is designed to survive such situations, and likely no damage will occur if it does. In this situation, however, immediately trying to start the generator may not work, it may need time to reset or cool adequately before restarting. Generally speaking, it is not recommended to run the RV vehicle motor and the generator while the RV remains stationary for long periods of time. -
Page 26: Conducting General Inspections
2. Perform air cleaner maintenance more often. 3. Change the engine oil more often. 4. Containers of engine oil that have been opened should be sealed tightly to keep out dust. Conducting General Inspections Inspect the generator before the first start of the day and after each eight hours of operation. Exhaust gas is deadly. -

5. If you smell the rotten eggs smell or LP, close the shut off valve on the LP tank immediately and have the tank serviced before continued use. Battery System 6. Check the battery terminals for clean, tight connections. Loose or corroded connections have high electrical resistance which makes starting the generator more difficult. -

years. Old gasoline will gum up the carburetor and require extra maintenance. Propane (LP) Use clean, fresh HD-5 grade liquefied petroleum gas (LP) or equivalent product consisting of at least 90% propane. Commercial LP fuels may contain more than 2.5% butane, which can result in poor fuel vaporization and engine performance in ambient temperatures below 32 degrees Fahrenheit. -
Page 32: Storing The Generator
Storing The Generator Proper storage is essential for preserving top generator performance and reliability when the generator cannot be exercised regularly and will be idle for more than 120 days. Gasoline 1. Fill the fuel tank with fresh gasoline and add a fuel preservative (stabilizer), for the proper amount to add simply follow the instructions on the container label. -
Page 33: Propane (Lp) Storage
Fig. 12 Propane (LP) Storage Check the local ordinances to determine if the RV may be placed in a garage. Generally, ordinances require that LP systems be leak free, that the LP container not be filled beyond specified limits, that the LP container shutoff valve be closed, and the RV not be parked near sources of heat or ignition. -

Need help?
Do you have a question about the Flex Power 4000i and is the answer not in the manual?
Questions and answers
We have a new 127 hr old RVMP 5500 i generator. It will not continue running. It was suggested that maybe the gas cap was not allowing proper ventilation. We have removed the gas cap from the motorhome but this continues to be a problem. Please advise, I can be reached at 913-238-6626. I have already left a message for a return call on your main line 855-427-7978. I look forward to hearing from you.
If the RVMP Flex Power 4000i generator does not continue running despite removing the gas cap, the issue may be due to a restriction in the gasoline line or vapor lock that is not fully resolved. Other potential causes include:
1. No or low fuel reaching the fuel pump.
2. A persistent vapor lock that continues to block fuel flow.
3. A separate fuel pump from the RV chassis engine or fueling station creating vacuum pressure the generator pump cannot overcome.
Even after loosening the gas cap, if the generator still does not stay running, there may still be a fuel restriction or vapor lock present in the gasoline line.

Why the generatrice 4000i does'nt have nothing power, does'nt start. Enough gas, can't start manuel, no start Because no power
If the RVMP Flex Power 4000i generator will not start and has no power, possible causes include:
1. Battery issues – Check if the battery is charged and connected properly.
2. Oil level – Ensure the oil level is adequate.
3. Spark plug problems – Check for spark and examine the spark plug for damage.
4. Fuel module issues – Listen for the fuel pump (gas) or solenoid click (LP) when pressing the start button. If silent, check the 10A fuse near the front control panel.
5. Electrical harnesses – Inspect all harnesses for loose or disconnected wires.
6. ECM failure – If fuel components work but the rotor does not spin, the ECM may be faulty. Try starting with the manual pull start to confirm.
7. Inverter issues – Although the inverter usually does not prevent starting, a bad inverter may cause no 120V output or throttle motor failure.
8. Throttle motor non-response – If the throttle motor does not adjust RPM under load, the inverter may be faulty.
Check each of these components systematically to identify and fix the issue.
