5I DELLMECO I AODD DIAPHRAGM PUMPS
!!!!
WARNING
!!!!
CAUTION
!!!!
When installing this product, be sure to connect a ground wire from the specified position of this product.
Otherwise friction between parts and abrasion caused by the flow of some fluids inside the casing may
generate static electricity. Depending on the type of fluid being pumped and the installation environment
(such as gases in the air and type of surrounding mixtures), static electricity could cause fire or electric
shock.
!!!!
Some fluid may remain inside the pump and inside the connected piping after shutting down the pump, or if
the pump is left unused for a prolonged period.
Therefore, be sure to purge the system of fluid and clean the pump before prolonged disuse.
The fluid remaining in the connected piping as well as the pump itself may expand because of freezing or
heat which may cause damage to the pump or/and piping and lead to leakage of the fluid.
Ø
Use only genuine Dellmeco parts when replacing component parts of this product.
!!!!
Torque of all tightening parts must be checked before running the pump. Designated torques are mentioned
in maintenance manual.
!!!!
In case of pumping a hazardous fluid (hot, flammable, strong acid, etc.) with this pump, protective measures
(install a pit, a protection box, sensors, etc.) must be provided in consideration of possible leakage of fluid.
Warning signs must be displayed at necessary places. Leakage of fluid may cause fire or accident.
!!!!
Before using this pump, get fully familiar with the precautions regarding the fluid to be pumped, and verify
the corrosion resistance of the parts that will come into contact with the fluid. NEVER use the pump with any
fluid against which it does not have sufficient corrosion resistance or with a fluid that poses a risk of
explosion. If you are unable to verify the corrosion resistance, contact your dealer. Using this product with
any fluid against which the parts in contact with the fluid do not have sufficient corrosion resistance may
result in damaging the product or leakage of fluid.
!!!!
The running pump may generate loud operating noise. Its level will vary depending upon the conditions of
use (fluid pumped, supply air pressure and discharge pressure)
!!!!
To drive this product, supply air with minimum moisture content and without any oil must be used.
!!!!
If a diaphragm of this pump is damaged, supply air may mix with the fluid or the fluid may flow into the
central housing. DO NOT OPERATE THE PUMP if air supply is inadequate or contaminated.
Ø
While operating this product, do NOT put your hand on the inlet port.
