■ 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 continu-
ous operation with clean water in a room temperature range of
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 in the following places 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.
