A circuit breaker must be installed for the unit.
Use supply wires suitable for 75°C

Caution: Single wall heat exchanger, is not suitable for potable water connection.

Installation

Based on the local climate conditions, construction features, and insulation level, calculate the required cooling (heating) capacity per square meter. Conclude the total capacity which will be needed by the construction. According to the total capacity needed, choose the right model by consulting the heat pump features as below:

Heat Pump Features
Cooling Only Unit: chilled water outlet temp. at 5-15°C, maximum ambient temp. at 43°C Heating and Cooling Unit: for cooling chilled water outlet temp. at 5-15°C, maximum ambient temp. at 43°C. For heating warm water inlet temp. at 40-50°C, minimum ambient temp. at -10°C.

Unit Application
The Evo Flex can be installed in houses, offices, hotels, and many more locations which require heating and cooling separation, with each area needing to be controlled independently.

Transit
If the unit needs to be hung up during installation, an 8-meter cable is required. There must be a soft material between the cable and the unit to prevent damage to the heat pump cabinet.

WARNING
DO NOT touch the heat exchanger of the heat pump with fingers or other objects!

Application of Heat Pump for Cooling

Location of Install & Minimum Clearances
The heat pump can be installed onto the concrete basement by using expansion screws, or onto a steel frame with rubber feet that can be placed on the ground or the roof. Ensure that the unit is placed horizontally.

The unit can be installed in any place outdoors which will be able to support the weight of a heavy unit such as a terrace, roof, the ground and any other places deemed suitable.
The location must have good ventilation.
The location must be free from heat radiation and other fire hazards.
A pall is needed in winter to protect the unit from snow.
There must be no obstacles near the inlet and outlet of the unit.
The installation location must be protected from strong winds or air.
There must be a water channel around the heat pump to drain condensing water.
Leave enough space around the unit for maintenance.

Water Loop Connection
Pay attention to the below matters when the water pipe is connected.

Try to reduce the resistance to the water from the piping.
The piping must be clear and free from dirt and blockage. A water leakage test must be carried out to ensure that there is no water leaking before the installation can be made.
The pipe must be tested by pressure separately. DO NOT test it together with the unit.
There must be an expansion tank on the top point of the water loop, and the water level inside the tank must be at least 0.5meters higher than the top point of the water loop.
The flow switch is installed inside of the heat pump, check to ensure that the wiring and action of the switch is normal and controlled by the controller.
Try to avoid any air from being trapped inside the water pipe, there must be an air vent on the top point of the water loop.
There must be a thermometer and pressure meter at the water inlet and outlet for easy inspection during running.

Electrical 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 wired 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.

Initial Start-up of the Unit

INSPECTION BEFORE TRIAL RUNNING

Check the indoor unit, and 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 the water loop is full of water and 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.

Installation Request:

The Factory only offers one main unit (1) in the legend, and the other modules which are indispensable fittings are provided by users or the installation company.
An automatic refill valve (10) is installed on the top point of the water system.
The quantity proportion of general valve (4) and three-way valve (5) is referred to the technical regulation, and there is a three-way valve installed in the farthest place of water systems.

Automatic Filled-Water
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, please operate as follows:

Open the Screw Cap ( C ).
If reducing the pressure of the water supply, unscrew the pressure to adjust the screw (B).
If increasing the pressure of the 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 the filled water. Then the handle (A) can return (close) when the system is full of water.

The automatic filled-water valve needs periodic cleaning. When you must close the tap, unscrew the plug (D), and 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.

Leakage Pressure Valve
The action pressure of the leakage pressure valve is more than 3bar (valve is open), but the pressure cannot be adjusted. The valve will open automatically to make sure that the water loop of the air-con system is safe when the water pressure in the backwater side is higher than the set pressure.

Assistant Heat Source Connection
The unit provides the connection of an assistant heat source which can not be only for a gas-fired boiler, but also for an electronic boiler or warm-net pipe for the city accordingly.

It is recommended that you get your EvoHeat 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?
EvoHeat has a large database of recommended service agents. Please contact EvoHeat 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.

What should I be checking regularly?
Check the water inlet/outlets often for leaks. You should avoid the condition of no water or air entering the system, as this will influence the unit’s performance and reliability.
The area around the unit should be dry, clean, and well-ventilated. Make sure there is nothing blocking the airflow of the heater e.g. Leaf litter. Check the power supply and cable connection often, should the unit begin to operate abnormally, switch it off and contact the qualified technician.
