Page 9: Precautions For Use
Precautions for use • Electrical work should be performed by a qualified electrician. Otherwise, personal injury or property damage may result. Caution • Do not install the pump in a place where the pump can get wet. Avoid using wet gas, or internal con- densation will build up and consequently result in the short lives of the valve and diaphragm. - Page 10 • Do not tube pump heads in series. It may prevent the motor from starting, causing burning out or may damage the diaphragm or piping. • Do not tube two or more pumps in series. It may prevent the motor from starting and lead to a burn out.
- Page 11 • The pump can not start with full discharge/suc- Suction pressure tion pressure. Remove pressure before operation. After a long period of stoppage, pump perfor- mance at the beginning of operation becomes occasionally unstable. In this case, warm the pump up for 10 minutes with no discharge line pressure.

Page 12: Overview
Introduction Pump structure & Operating principle The APN-P110-D4 is a diaphragm type air pump with a brushless DC motor. The rotary motion of the motor is converted through a connecting rod to the reciprocation of the diaphragm in the pump chamber, where gas is transferred from the inlet to outlet. -
