Maintenance
■ Wear parts
If pump performance has remarkably reduced, replace dia-
phragms and valves with new ones. Wear part duration varies
with the pressure, temperature and characteristics of gas/
liquid.
The estimated life below is calculated based on continuous
operation with clean water at ambient temperature (Room tem-
perature range is 0-40°C.).

■ Cleaning
Turn off power and wait until the pump has cooled down. Then
clean off the surface of the pump with a wet cloth. Use a neu-
tral detergent for greasy dirt as necessary and dry it with a dry
cloth.
Check the pump surface has dried up before operation.
CAUTION
Risk of electrical shock. Do not wet electric parts or wir-
ing.
■ Storage
Protect the pump from dust during storage.
Do not store the pump:
• Where ambient temperature falls below 0°C or exceeds 40°C.
• Under a flammable or corrosive atmosphere.
• Under heavy dust or high humidity.
•
Under direct sunlight or wind & rain.
•
Under vibration.
