This document provides operating instructions for the Einhell ROYAL HW 1300 Niro/Niro House Waterworks, a domestic water pumping system.

Function Description:

The Einhell ROYAL HW 1300 Niro/Niro House Waterworks is designed for various domestic water supply applications. It functions by drawing clear water (fresh water), rainwater, or mild suds/service water from a source and delivering it under pressure. The system is equipped with a motor protected by a built-in thermostat, which automatically switches off the pump in case of overheating or blockage and restarts it after cooling. A pressure tank with an expandable water sack and an air compartment ensures consistent pressure delivery. The pump automatically switches on when water is consumed and the pressure drops, and switches off when the desired switch-off pressure is reached.

Usage Features:

The house waterworks is intended for several applications:

Irrigation and Watering: Suitable for green areas, vegetable beds, and gardens.
Lawn Sprinkler Operation: Can be used to operate lawn sprinklers.
Water Drawing: With a pre-filter, it can draw water from ponds, streams, rain barrels, rainwater cisterns, and wells.
Domestic Water Supply: Provides water for household use.

For optimal performance and to prevent damage, it is recommended to use a pre-filter and a suction set comprising a suction hose, a suction basket, and a non-return valve. The suction line should have a minimum diameter of 1 inch (1 1/4" is recommended for suction heads over 5 m) and be laid at an ascending gradient from the water source to the pump to avoid air bubbles. The suction valve should be deep enough in the water to prevent dry running. The delivery line, with a minimum diameter of 3/4", should be securely connected. During priming, any shut-off mechanisms in the delivery line should be fully open to allow air to escape. The appliance should be set up on a firm, level, and horizontal surface, and the pump case should be filled with water through the delivery line connection to accelerate priming.

Maintenance Features:

The house waterworks is largely maintenance-free, but regular inspection and cleaning are recommended for a long service life.

Safety First: Always disconnect the appliance from the power supply by pulling out the power plug before performing any maintenance.
Storage: For long periods of non-use or winter storage, the pump should be thoroughly rinsed with water, completely emptied, and stored in dry conditions. In freezing conditions, ensure the house waterworks is completely drained.
Rotor Check: After a lengthy stoppage, briefly switch the appliance on and off to check that the rotor turns freely.
Clearing Blockages: If the system becomes clogged, connect the delivery line to the water pipe, disconnect the suction hose, open the water pipe, and switch on the pump several times for approximately two seconds. This method often clears blockages.
Pressure Tank Maintenance: The pressure tank contains an expandable water sack and an air compartment, with a maximum pressure of approximately 1.3 bar. If the air pressure is too low, it should be topped up. Unscrew the plastic lid from the tank and use a tire pump with a meter at the valve to add the missing pressure.
Cable Replacement: If the power cable is defective, it must be replaced by a qualified electrician.
Dry Running Prevention: It is crucial to never allow the house waterworks to run dry, as this can cause damage and void the manufacturer's warranty.
