Page 19: Before Use
Installation 1. Before Use “Strictly observe the following points.” Operators and maintenance service staff must read the instruction manual thoroughly before using the products. Do not operate the pump system unless all of the contents in the manual are completely understood. CAUTION ●... - Page 20 Installation ● The pump can be operated outdoors, as the pump employs a simple water and dust proof structure. However, when installing the pump, avoid places exposed to direct sunlight or direct rain with an ambient temperature of above 40ºC, or with a rela- tive humidity of above 90%.
- Page 21 Installation ● Limited operating site and storage Do not install or store the pump in the following places: * Places where a flammable gas or material is used or stored. Prohibited * Place where the ambient temperature is extremely high (40ºC or higher) or extremely low (0ºC or lower).

Page 29: Bleeding
Operation 1. Bleeding After the installation, piping, and wiring processes are completed, operate the pump in accordance with the following steps. CAUTION ● Do not operate the pump with a completely closed discharge-side valve. Operating the pump with the discharge-side valve fully closed may lead to liquid leakage or pipe rupture. - Page 30 Operation SH type [4] Rotate the air vent adjusting screw clock- Air vent wise to close the air vent valve adjusting screw Male connector [5] Inspect various points for liquid leakage to complete the air elimination process. <Bleeding for EW-F31, G31, 36, 46 models> [1] Extend the tube connected with the dis- charge-side fitting nut of the pump to the liquid tank or something like a drain plate.

Page 31: Flow Rate Adjustment
Operation 2. Flow rate Adjustment The discharge amount can be adjusted by two methods, namely, stroke speed adjustment and stroke length adjustment, the former being used in most cases. In the event the expected discharge is not exactly obtained by the stroke speed adjustment, the stroke length adjustment is employed as a supplementary. [1] Procedure for flow rate adjustment 180 spm Fixed stroke rate... - Page 32 Operation [3] Adjustment of stroke length Stroke length can be adjusted by changing the degree of plunger return. (1) Start the pump and rotate the stroke length adjusting dial while operating the pump to adjust the discharge amount. (2) The relation between discharge amount and stroke length is as shown in the Fixed stroke rate graph on the left, where the discharge...
