Installing the product
! WARNING
• This pump does not have explosion-proof specifications. Do not install it in explosion-proof regions or
in explosive or combustible atmospheres.
• Install the pump in a location that cannot be accessed by anyone but control personnel.
! CAUTION
• Do not install the pump where there is a risk of flooding or where there are high levels of moisture or
dust. Doing so may cause electric shocks and/or malfunctions.
• This pump has a water-proof construction (equivalent to IP65 under IEC standards). However, it is made
of plastic so make every attempt to avoid installing it in a position that will shorten its service life (such
as a position where it will be exposed to direct sunlight, wind or rain).
Installation location
• Avoid installing the pump in a location exposed to direct sunlight or wind and rain. Although it features a water-proof
construction (equivalent to IP65 under the IEC standards), direct sunlight may cause the temperature of the metal
parts to rise, ultraviolet rays may cause the plastic parts to deteriorate, and sand, dust, and rainwater may damage or
corrode the pump body. When installing the pump outdoors, it is recommended that an awning or cover be installed to
protect the pump from the elements and extend its service life.
• Install the pump in a location where the ventilation is good and where the chemical will not freeze.
• Provide adequate space around the pump to facilitate maintenance and inspections.
• Place the pump in a level location, and secure it so that it will not vibrate. Installing the pump at an angle may result in
discharge trouble or in the inability of pump to discharge.
Mounting bolt positions
Use the pump-mounting bolts (×2) provided to secure the pump.
✽ The pump can be installed at any pitch ranging from 87 to 110 mm.
