Installation (Continued)

NOTICE

An air leak in the

suction line may

 

prevent priming of the pump. Use of thread sealant is recommended.

Suction lines must be reinforced hose or rigid pipe. Non-reinforced hose will collapse due to the suction created by the pump and prevent pump from operating.

3.A check valve must be used in the suction line to maintain the self- priming capability. If no check valve is used the pump will need to be primed at the start of each operation. For best operation, the check valve should be installed at the intake of the suction line.(Figure 2).

Figure 2

4.A suction strainer is required to filter abrasive material.

5.The discharge hose and fitting should be leak-tight. A leak in the discharge hose will allow water to spray around the work site, making the site hazardous.

6.Keep all pipes and hose lines as short and straight as possible. Long lengths and curves in the pipes and hose lines will reduce the pressure the pump develops.

7.Fill the engine crankcase with oil. Refer to the engine operating manual for the specific grade of oil and amount required.

8.Fill the engine fuel tank with gasoline. Refer to the engine operating manual for specific gasoline type that is most efficient for this engine.

9.Add water to the priming port on the pump (See Figure 3). Continue adding water until the water level is approximately 3 inches from the top. Install the priming plug. The water in the pump will create the suction that primes the pump.

10.Turn fuel valve to ‘ON’ position.

11.Move choke lever to ‘CHOKE’ position.

12.Move throttle lever to ‘START’ position.

13.Pull engine crank until engine starts. Once engine starts, move choke lever to ‘RUN’ position.

14.The pump will take several minutes to prime.

PIPING

Always place the pump as close as possible to the liquid being pumped. Keep all pipe and hose lines as short and straight as possible.

Support pump and piping when

assembling and after installation. Failure to do so may cause piping to break, pump to fail, etc; all of which can result in property damage and/or personal injury.

All suction connections must be airtight. If the pump won’t prime, check for leaks in the suction piping or fittings. If flexible suction hose is used instead of pipe, use reinforced hose with a two inch inner diameter. Non-reinforced flexible hose may collapse from the vacuum created as the pump primes.

Always use a strainer at the end of the suction pipe or hose. Position strainer so it doesn’t become clogged with stones or debris. A suction line check valve is

recommended.

Do not use this pump for suction lifts over twenty-five feet.

Maintenance

Always shut off the engine, allow the engine to cool, and remove the spark plug before performing any maintenance.

During freezing weather, open the drain port and allow all the water in the pump to drain. This will prevent damage to the pump when the water freezes. If the pump will be stored for a month or more, drain the water from the pump and follow the engine manufacturer’s recommendations for long-term storage.

The Honda engine is equipped with a low oil shut off sensor. The engine will shut down and will not restart if the oil level becomes low.
