4. Installation

4.1 System Installation

·

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.

For 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.

4.2 Plumbing
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.

4.3 Electrical Connection
IMPORTANT: Always use a qualified Electrician to perform any electrical work. A licensed electrician must read the information before connecting.

Ensure the power cable and circuit breaker are of a suitable size for the heater being installed. Also check that there is adequate voltage and current available at the heater connection to run the unit.

·

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.

4.4 Initial Start-up
Pre-Start Inspection

·

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.

8. Maintenance

Page 16 Evo Ultra Manual

DO I NEED TO GET MY UNIT SERVICED?

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 have 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.

Check the water inlet/outlets often for leaks. You should avoid the condition of no water or air entering into the system, as this will influence unit’s performance and reliability.

You should clear the pool/spa filter regularly to avoid damage to the unit as a result of the dirty of clogged filter.

WHAT SHOULD I BE CHECKING REGULARLY?

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.
Discharge all water in the water pump and water system, so that freezing of the water in the pump or water system does not occur. You should discharge the water at the bottom of water pump if the unit will not be used for an extended period. You should check the unit thoroughly and fill the system with water fully before using it for the first time after a period of time.

Check the power supply and cable connection often, should the unit begin to operate abnormally, switch it off and contact the qualified technician
