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.

- 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.

Automatic Water Filling Valve
When the automatic filled-water valve is installed, the arrowhead orientation
of inlet water must accord with the orientation of the valve.
Automatic filled-water has been adjusted in advance to 1.5ba.
If readjusting the pressure of inlet water, operate as follows:
- Open the Screw Cap ( C )
- If reducing the pressure of water supply, unscrew the pressure to adjust the screw (B)
- If increasing the pressure of water supply, screw down the pressure to adjust the screw (B)
When the system needs to be filled with water at first, rest the handle (A) of
filled-water. Then the handle (A) can return (close) when the system is full
of water.
Automatic filled-water valve needs periodic cleaning. When you must close the
tap, unscrew the plug (D), remove the inside filter net. Reassemble after
cleaning.
NOTE:
There are two connections for water pressure meters in the central section of
automatic filled-water, where the water pressure meter can be connected
directly and display the set pressure. The screw cap ( C ) must be tweaked
after adjusting the filled-water pressure.
Maintenance
DO I NEED TO GET MY UNIT SERVICED?
It is recommended that you get your Evo Heat unit serviced once a year by your
local certified air conditioning or refrigeration technician. If your unit is
located in a coastal area, more frequent maintenance may be necessary.
During the service, they will check the operational pressures of the
refrigeration system and give the unit and fins a good clean to ensure maximum
performance.
DO WE HAVE RECOMMENDED SERVICE AGENTS?
Evo Heat have a large database of recommended service agents. Please contact
Evo Heat tech support on 1300 859 933 for your local service agent details.
SHOULD I CHECK MY UNIT REGULARLY?
We recommend you check your unit regularly to avoid potential issues and
damage to your heat pump.
- Always remember to check the water system filling equipment and air exhaust equipment in case of water interruption or air entering the system; Make sure to clean the water filter in case of blockages. The system will check the water pump every 72hrs at standby status.
- Wash the water circuit system in the unit every 6 months; Remember to check the working status of every component and check whether the working pressure is in normal range or not. If anything is abnormal, repair or replace. Remember to check the power and wire connection. If anything is abnormal, repair or replace.
- If the unit is not to be used for an extended period of time, drain the water in the water pump and water circuit from the bottom water exit so it does not freeze. If you want to start the unit again, fill water to the system and conduct a complete inspection before start-up.
- If you are not using the unit continuously, please do not turn off the power in case of spare parts freezing. Evo Heat will not take any responsibility if any damage occurs because of this mis-operation.
