Initial Operation, Thermal motor protector

	Notes on use	v Clear the outlet line before use.
		Dry-running operation causes increased wear and is to be
		avoided. Therefore, in manual operation the pump must be
		immediately unplugged when water fails to flow.
		Avoid running of the pump for more than 10 min. against closed
		delivery side of the pump.
		Take care that the pump is located where the inlet openings at
		the suction base are obstructed neither completely nor partly.
		Stand the pump on a brick if using in a pond.
	Thermal motor protector	The pump is automatically switched off on overheating by
		the built-in thermal motor protector. After having cooled down,
		the motor automatically switches on again (see 6. Trouble
		Shooting).
	Automatic deaerating	The automatic deaerating valve eliminates any air pockets in
	valve	the pump. During this process, air escapes through the vent
		bores 4 and air bubbles appear underwater. This is not a defect
		of your pump, but serves to deaerate the pump.
	4	It may take several seconds for the air to escape when the

The following connection kits are required for 13 mm to 19 mm connections:

13 mm (1/2 ”): GARDENA Pump Connection Set, Art. No. 1750

15 mm (5/8 ”): GARDENA Tap Connector, Art. No. (2)902, and

Standard Hose Connector, Art. No. (2)916
