Operational Principle

According to Reverse Carnot Cycle theory and the same process as normal water source heat pump units, The Evo Ultra absorbs heat from soil and transfers the heat to water as the soil temperature is generally stable, i.e., the heat source is stable, the units work capability will not change with the ambient temperature.

 Technical Data

Heating:

• Heat source side: water inlet/outlet temperature: 20°C/15°C
• User side water inlet/outlet temperature: 65°C/75°C
• When the units work between 55-85°C, make sure the low-pressure range is between 0.27-0.65MPa and the evaporating temperature is between 7-30°C.
• The above data is for reference only, specific data is subject to the product nameplate.

Safety Instructions

•  Installation, repair or relocations must be done by a fully qualified person and not by the customer. If done incorrectly it may cause fire, electric shock, water leakage and other hazards.
• Maintenance and operation must be carried out according to the recommended time and frequencies, as stated in this manual.
• To avoid risk of electrical shock, the unit must have a good power connection and earthing.
•  Use genuine standard spare parts only.
•  When an abnormality (smell of burning, etc.) occurs, stop the unit and disconnect the power or turn off the breaker. If the unit continues to be operated in an abnormal condition, it may cause a fire or hazards.
•  Do not insert fingers or objects into the fans or evaporator of the unit.
• You should have a program to ensure personal safety in the case of a refrigerant leak when the unit is installed in a small room.
•  For unit cleaning or maintenance, switch off and disconnect the power of the unit.
• Do not install the unit near flammable gas or spray flammable substances near it.

Installation

Installation Notes

•  Choose the right product model according to climate, architecture and insulation situation.
•  Read the product user guide before installation and clearly understand what each label means. Please install, test and maintain the units according to the user guide.
• Check every attachment in case of omission.
•  This model can be installed on a concrete base with expansion bolts or installed on the ground or roof by a steel bracket with rubber cushion. Make sure that the units are horizontally placed.
• The units should be installed at a place convenient for installation and maintenance.
•  The units should install shock-absorbing devices in case of the shock transferring to the building.
• Rigid pipelines in the engine room should adopt spring shock-absorbing brackets.
•  Units should be installed indoors or outdoors with a shelter.
• Units should be installed somewhere with no radiation or other heat sources.

Transit

Use four slings longer than 8m when moving the units and use the lifting holes on the bottom board. Put a cushion block at the places of contact in case of damage.

Water Pipeline Connection

When connecting the water pipeline, you cannot exchange the user side pipeline with the heat source side pipeline. The unit’s user side and heat source side direction should be in accordance with the direction as marked on the units. Water pipeline resistance out of the units should as minimal as possible. The pipeline must be clean to prevent jamming. Before packing the insulation layer, a leakage test should be conducted. Adopt the same diameter water pipe as mentioned in the user guide for inlet and outlet connection pipe out of the units. Ensure that the pipeline is full of water and has fine moisture measures when the unit is at work. The Expansion water tank should be equipped at the highest part of the water pipeline. The water surface of the expansion water tank should be 0.5m or higher than the highest point of water pipeline.
Choose the insulation water tank with suitable volume according to the units heating and cooling capacity and ensure the insulation of pipeline out of the water tank.
If the units have no water pump equipped, please choose the proper water pump according to the units water flow volume on the user guide, making sure the water flow volume satisfies the units requirement. There should be hose connection equipment between the water pump and units. If the water pump is installed outdoors, there should be water-proof and anti-freezing equipment. An automatic exhaust air valve should be equipped at the highest point of the water pipeline in case of air detention in the pipe; Drainage valve should be equipped at the lowest point of the water pipeline, so it can be convenient for maintenance and drainage. A Y-type filter should be installed at the circular water pump inlet port of the user side and heat source side in case that impurities may damage the units. The Y-type filter should be detachable for cleansing and maintenance. Softened water can be better for circular water. The connection of the water inlet and outlet should be flexible to reduce vibration.  Drain out the water in the pipeline when you will not use the units for a long time in case of freezing. Do not change the set return water temperature and water tank insulation temperature.
Thermometer and water pressure gauge should be equipped at the units water inlet and outlet port for checking. User side water should be tap water and the hardness should be less than 20. If not, install an electric hydro treater at the tap water side.

Power Supply Connection

•  Open the front panel and open the power supply access.
• The power supply must go through the wire access and be connected to the power supply terminals in the controlling box. Then connect the 3-signal wire plugs of the wire controller and main controller.
•  If an external water pump is required, please insert the power supply wire into the wire access and connect it to the water pump terminals.
• If an additional auxiliary heater is needed to be controlled by the heat pump controller, the relay (or power) of the aux-heater must be connected to the relevant output of the controller.

Trial Operation

Inspection before trial running

•  Check the indoor unit, make sure that the pipe connection is done correctly, and the relevant valves are open.
•  Check the water loop to ensure that the water inside of the expansion tank is filled to an appropriate level, the water supply is working and that the water loop is full of water & free of trapped air. Make sure there is good insulation for the water pipe.
•  Check the electrical wiring. Make sure that the power voltage is normal, the screws are fastened, the wiring is made in line with the diagram and that the earthing is connected.
• Check that the heat pump includes all the screws and components, and that they are in good order. When powering the unit on, review the indicator on the controller to see if there is any indication of failure. The gas gauge can be connected to the check valve to see the high pressure (or low pressure) of the system during trial running.

Trial Operation

• Start the heat pump by pressing the ON/OFF key on the controller. Check whether the water pump is running, if it runs normally there will be 0.2MPa on the water pressure meter.
•  When the water pump has ran for a minute, the compressor will start. Listen for any strange sounds from the compressor, if an abnormal sound occurs please stop the unit and check the compressor. If the compressor runs well, please look for the pressure meter of the refrigerant.
•  Check whether the power input and running current is in line with the manual. If not, please stop and check.
•  Adjust the valved on the water loop to make sure that the hot (cool) water supply to each door is good and meets the requirements of heating (or cooling).
•  Review whether the outlet water temperature is stable.
•  The parameters of the controller are set by the factory, the user cannot change these themselves.
