GENERAL INSTALLATION INSTRUCTIONS
1. Before installing the pump, check whether the pipeline system is connected reliably and ensure that impurities, welding
slag, dirt and the like in the pipeline have been removed. The output of the voltage adapter is low-voltage DC 24V.
During installation, a filtering screen can be installed at the inlet of the recirculating pump to filter large particles and
impurities in the water, and the filter screen shall be cleaned regularly. It depends on the pipe water situation. You can
choose to install or not. If the water in the pipe is always clean, you don’t need to install this screen.
2. The HIP24-12A pump must be installed or maintained by a professional plumber . Install the pump according to the
installation diagram of the HIP24-12A pump. Pay attention to the water pipe connection between the water inlet and
the water outlet. After installation, check the HIP24-12A pump and all water pipe fittings for water leakage
.
The
HIP24-12A pump shall be prevented from being splashed by water to avoid electric shock.
3. After connecting the power adapter, conduct a test run of the recirculating pump to check whether the startup is normal,
but the nonwater running time should not exceed 5 seconds to prevent the operation from reducing the bearing life.
4. When the HIP24-12A pump works, if you want to adjust the position of or touch the recirculating pump,the power supply
must be the first cut off to prevent accidents.
5. Carry out regular inspection and make replacement in time when damage occurs.
6. If the HIP24-12A pump is not used for a long time or no one is at home, please close the water pipe valve at the inlet
and outlet end and cut off the power supply of the recirculating pump.
7. Cable or power adapter, when damaged, must be replaced.
8. In winter, when the ambient temperature is lower than 0°C, if the electric pump stops running, the water in the pipeline
system must be drained to prevent the pump from freezing and cracking.
Installation tips
Installation steps
1. For Electric Water Heater : Turn off Power to your Water Heater. ( turn off power at breaker box ). For Gas Water
Heater : Turn off the gas to your water heater and ensure that the pilot light is not burning. Shut off the supply water
valve to the water heater. In most cases, the supply water valve located above the hot water heater on the cold water
inlet to the hot water heater.
2. Drain the water from the backwater pipe by opening a cold water faucet in the house. Let the water run until it stops
flowing. Then drain remaining water from hot water heater spigot. Leave the faucet open until the pump installation is
complete. If water does not stop flowing, check to make sure the water to the hot water heater has been completely
shut off.
3. Disconnect the backwater pipe with the water heater.
3.2 (optional)Find a suitable installation position (on the back water pipe near the water heater end). When installing
the water pump support plate in advance, the support plate can be placed in the pre-installation position and marked
with a marker at the installation hole. The drilling size is φ6.

3.3 Insert the plastic expansion screw into the hole drilled in the wall.
3.4 Fix the support plate on the wall with self-tapping screws.
3.5 Clip the pump onto the hook of the support plate indicated by the arrow.
