Notes for operation | 
| At initial operation after installation, please remove the priming plug on the upper part of the pump casing and fill the pump with water. |
| If there is the possibility of freezing in the pump casing when the pump is stopped under freezing conditions, remaining water inside the pump should be drained off by removing the drain plug on the lower part of the casing. |
| It is characteristic of this type of pump that capacity decreases and horse power increases when total head is high, therefore please make sure that the valve on the discharge side is not shut off during operation. |
| Installation and piping: Please install an inverse U-bent pipe as suction piping for efficient self-priming. For details, please refer to the page for the UHN type. |
Specifications stated here may be subject to change without notice due to product improvement.
