Product Overview
• HEATIT HIP smart hot water recirculating pump adopts a plastic-sealed permanent magnet synchronous motor with
ultra-low safe voltage (24V).
• Easy to install with the necessary accessories included. 10' power cord. Built in thermostat. Maintenance free. Can be
used with all types of pipe.
• Three modes can be chosen: energy-saving constant temperature mode, smart constant temperature mode and manual
mode. When the water temperature in the pump is lower than 33 ℃, the pump will push the cold water back to the water
heater. As the temperature hits 38 ℃, the pump will stop working.
• Advanced motor technology: Permanent magnet brush less motor DC motor makes the pump more powerful, more
quiet and more durable. (Max flow 6 GPM, Max head 39.3ft)

Important safeguards and warnings
• Please read the Instruction Manual and keep it properly before installing and using the product.
• The electric pump must be reliably grounded before use, and leakage protection devices should be installed.
• It is forbidden to touch the electric pump during operation.
• Dry running of the electric pump is strictly prohibited.
• It is strictly prohibited for children, and persons with no capability or limited capability to use the product without
supervision of guardians (such as not being taught the safe use method of the product and understanding the risks
involved).
• The pump system must be able to withstand the maximum pump pressure.
• The manufacturer shall not be held responsible for any consequences caused by the user modifying the electric pump
without authorization or operating the electric pump beyond the operating conditions.
Thank you very much for choosing our products. Please read the Instruction Manual carefully and keep it
properly before installation and use.
GENERAL INSTALLATION INSTRUCTIONS
The product is installed under the faucet furthest from the water heater in each loop.
Conveying liquid
The conveying liquid is softened water and thin, clean, non-corrosive, non-explosive liquid without solid particles, fibers
and mineral oil, and the PH value of the medium is between 6.5 and 8.5.
The requirements for the operation system of the electric pump are shown in the following figure 2 :
Medium and ambient temperature
The system temperature (t1) must be always higher than the ambient temperature (t2) in order to avoid electrical short
circuit of junction box caused by condensation of pump body(see figure 3).
Installation tips
Maximum pressure borne by electric
pump 145 PSI
If the pressure difference between hot and
cold water pipes is greater than 1.45 PSI,
the backwater device may not return water
normally, thus affecting the use effect.
Min. liquid temperature·····35.6℉

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.

GENERAL INSTALLATION INSTRUCTIONS
2.The HIP24-12B pump must be installed or maintained by a professional plumber . Install the pump according to the
installation diagram of the HIP24-12B pump. Pay attention to the water pipe connection between the water inlet and the
water outlet. After installation, check the HIP24-12B pump and all water pipe fittings for water leakage (seepage). The 、
HIP24-12B 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 HIP24-12B 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 HIP24-12B 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 recircylating 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 steps

7.2 (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.
7.3 Insert the plastic expansion screw into the hole drilled in the wall.
7.4 Fix the support plate on the wall with self-tapping screws.
7.5 Clip the pump onto the hook of the support plate indicated by the arrow.
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. 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.
3.Drain the water from the pipe by opening the water faucet in the house. Let the water
run until it stops flowing. 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.
4.Disconnect the hot water line to the faucet with the hot water angel valve Connect the
brass Tee to the 1/2” NPT inlet of the pump. Please make sure the rubber gasket is in
the brass Tee. Connect this faucet hot water line to this brass tee and then connect
one 1/2 inch supply line (which was provided in the package) to this brass Tee. After
that connect this 1/2 inch supply line to the hot water angel valve.
5.Disconnect the cold water line to faucet with the cold water angel valve. Connect the
brass Tee to the 1/2” NPT outlet of the pump. Please make sure the rubber gasket is
in the brass Tee. Connect the faucet cold water pipe to this brass tee and then connect
one 1/2 inch supply line (which was provided in the package) to this brass Tee. After
that connect this 1/2 inch supply line to the cold water angel valve.
6.Use pipe dope or Teflon tape to seal threads when connecting to a 1/2 female NPT connection. If a gasket flexible
copper water heater connector is used pipe dope or Teflon tape is not required.
7.Ensuring that the pump shaft is horizontal.

The product is divided into three gears. When running, the gear is indicated by the
rotating speed of the light bar. The faster the rotating speed is, the higher the gear is.
When the water temperature of the pipeline is lower than 5℃for 30s, the electric pump
will operate until the water temperature meets 10C. If the water temperature can’t meet
10C, a buzzer will sound to give an alarm.

8. Reopen the supply valve to the hot water heater and allow the water to run until all the air has been purged from
the piping.
9. Close faucet inside the house.
10. Plug the line cord of the pump into a 115V outlet. Be sure to route the power cord so that it does not touch the
exhaust vent piping of a gas or oil-fired hot water heater.
