I. Introduction
Safety precaution
Caution: Danger of electric shock
Always switch off power supply before working on the heat pump and stop the hydraulic circuit.
- The swimming pool heat pump must be installed by a qualified electrician.
- Always install a differential protective device with a sensitivity of 30 mA on the distribution unit before the electrical box.
- Always fit a circuit breaker for all active conductors on the power supply of the box.
- In case of abnormal behavior (noise, smell, smoke), cut off the power supply immediately and contact you reseller. Do not attempt to repair the system yourself.
- Keep the main power supply switch beyond the reach of children.
- Rotating parts: Never remove the grid from the fan. Never place your hand or any other object in the air inlet or outlet of the heat pump.
Important features of this product
This swimming pool heat pump is equipped with safeguards that will stop operation to protect your unit automatically and display error code on the LED controller in case of some events as following:
Water Flow Switch
The water flow switch contacts are closed when pressure is applied as pool water flows through the titanium heat exchanger. Low flow rates as well as no flow will let these contacts open and this will cause the unit to shut down. The LED display will read “EE3” if the water pressure is not sufficient.
High / Low Refrigerant Pressure Switches
- The high-pressure switch senses the refrigerant pressure in the sealed refrigeration system and shuts the heat pump down in the event unsafe operating pressures are reached. The heat pump will automatically reset after the system pressure drops back to normal operating pressures. When this switch is tripped, digital displays will read “EEI”
- The low-pressure switch senses the refrigerant pressure in the sealed refrigeration system to protect against certain conditions that could be detrimental to compressor life. The switch shuts the unit down in the event of loss of refrigerant or not enough refrigerants. The switch automatically resets when the pressure rises to normal operating pressures. The display will show “EE2” if this switch is tripped.
Low Ambient Temperature
If the air outside the heat pump is not warm enough to produce heat, the system will shut down. The actual point at which your unit will shut down due to low temperature varies depending on current weather conditions and on the amount of sunlight reaching the heat pump. The shutdown can occur anywhere within a wide range of temperatures, usually below 0 degrees. A shutdown occurs when the air temperature sensor detects the ambient temperature is lower than 0 degree (digital controller will display a code "PP7"). The unit will start up again when the temperature has raised enough to reset this switch.
Time Delay
All models use a 3-minute time delay to prevent repeated tripping of the compressor thermal overload, which is caused by attempting startup before system pressures are equalized. Any interruptions, outside of power loss, will result in a 3-minute time delay.

II. Installation Guide
Attention!
This swimming pool heat pump must be installed by a skilled team.
Transport it in proper manner
I. Transport it in original package.
2. When moving the machine, do not lift the water nozzle since the titanium heat exchanger in side the machine will be damaged. Please refer to the following wrong operation picture:

text_image
Diagram showing hand positioning with a red X mark inside a box, possibly indicating a defect or error.
!!Warning:
Because the machine is very heavy, the water nozzle can not bear to be lifted during transit or installation
The manufacturer cannot accept responsibility for damage incurred or repairs necessitated due to improper handling of our equipment.
Determining Optimum installation position
The location of the swimming pool heat pump is very important for efficient operation, think about the following factors when choose the proper place:
✨ Avoidance of air recirculation
✿ Easy for wire and pipe connection and Water pipe line of long water lines (not longer than 10m.) from heater to pool.
✨ Easy for maintenance.
✨ Drainage of condensation.
Pay attention to the following points:
I. The heat pump must be installed OUTSIDE in a well ventilated place to avoid air recirculation or in a place with adequate room area both for installation and maintenance. Please refer to the following illustration:
A minimum of 500mm of clearance from walls, shrubbery, equipment, etc. is required around the entire pump circumference. This allows for ample air intake. No less than 2500mm clearance on the air outlet is required to prevent recirculation of air. We recommend not to place the unit underneath eaves, decks, or porches, as this causes recirculation of discharged air, or the efficiency of the heater will be reduced or even stopped.

!!Warning:
Don't install the heat pump close to a wall or
plants. And Never inside a closed building!
- The heater should be located on a solid, level and non-corrodible structure that is capable of supporting the weight of the heat pump. It must be fixed by bolts (M10) to concrete foundation.

!!Warning:
The machine must not be hung onto the wall with soft pipe since the inlet/outlet union on the machine can't hold weight.
The machine must always be connected with hard pipe!
- The heat pump should be far from any source of combustibles and corrosive material to avoid any damage to this unit.
Never place heat pump near sprinkler systems, evaporation of acid or alkaline gas. If you live in an oceanfront area, the heat pump should be placed out of direct spray of sand and salt, since this will also clog, damage, and corrode the unit. You may consider protecting your heat pump by planting shrubbery or a privacy fence between the unit and the prevailing beachfront wind.
- When the machine is running, there will be condensation water discharged from the bottom. Make sure there is enough space for water drainage.
TIPS: HEAT PUMPS GENERATE WATER CONDENSATION DURING NORMAL OPERATION. THIS SHOULD NOT BE MISTAKEN FOR A LEAK IN THE UNIT.
Water pipe connection
- The water flow through this machine needs to be driven by an appended water pump (Prepared by the user). The recommended pump specification-flux is shown on the product specification and Max. lift ≥10m;
- Pipe length between heat pump and swimming pool should not be longer than 10m.
