• If the unit stops and you restart the unit or turn it on manually, the unit will not start to run again for approximately 3 minutes. This is a protection feature to safeguard the compressor.
• The handle of the P&T safety valve should be tested once every six months to remove the calcium carbonate deposits and guarantee there is no blockage in the device.
• Once installation is complete, check that all connections are secure before the power is turned on.
• The installer is to explain to the end user how to operate and maintain the unit in accordance with this instruction manual.
• Evo Industries Australia Pty Ltd will not be held responsible for any damages or injuries caused by the incorrect installation of this hot water system.
• A maintenance programme must be carried out as recommended in this manual to ensure ongoing reliability.

To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment required by local codes and no less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSIZ21.22. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the valve into an opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve exits only within 6 inches above, or at any distance below, the structural floor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances.

Hydrogen gas is produced in a hot water system served by this heater that has not been used for a long period of time (2 weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance.

The appliance is fitted with means for disconnection from the supply mains having a contact separation in all poles that provide full disconnection under overvoltage category lll conditions, and these means must be incorporated in the fixed wiring in accordance with the wiring rules.

Installation

System Installation

Upon receiving the unit, check the packaging for any obvious signs of damage. Inform EvoHeat immediately if there is any evidence of rough handling.

Do not drill any fixings or attachments into the outer casing of the tank. Drilling into the outer casing of the tank may damage the heating coil and WILL VOID WARRANTY.

The P&T valve attached with the unit must be installed. Failure to do so will cause damage to the unit and possible personal injury.

Drain the water tank through the drain valve at the bottom part of the unit.

Do not use stainless steel fittings to connect directly with other metals to prevent galvanic corrosion.

Note: A pressure releasing valve is to be fitted within the installation. Spec of P&T valve: Pressure: 0.85MP Temperature: 99°C

Water Inlet or Outlet Pipes: The specification of the water inlet and outlet thread is BSP3/4 (internal thread). Pipes must be heat-resistant and durable.
Piping for the P&T Valve: The spec of the valve connecting thread is BSP3/4 (internal thread). After installation, confirm that the drainpipe outlet is exposed in the air. When the flexible drainpipe is joined to the pressure relief orifice of this valve, ensure that the flexible drainpipe is pointing downwards and exposed in the air.

Handing & Transportation

The unit should be stored and/or transported in its shipping container in an upright position and without water charge. For transport over short distances, and provided due care is exercised, an inclination angle of up to 30 degrees is permitted. During transport and storage, ambient temperatures of -10 to +60 degrees Celsius are permissible.

Forklift Transportation
The unit must remain mounted on the pallet and lifted at minimal speed. Due to its top heaviness, the unit must be secured against tipping over and placed on a level surface.

Manual Transportation
Ensure that the maximum permissible inclination angle of 60 degrees is not exceeded. If transport in an inclined position cannot be avoided, the unit should be left to rest at least one hour after it has been moved into final position before operation.

Location of Installation

The Evo315-C is designed for external installation, however, where possible installing the unit under the house eaves or in a sheltered environment may help prolong the life of the system.
Heat pumps operate most efficiently with warmer air temperatures, and the outlet air from the unit will always be colder than the inlet air. Therefore, it is advisable to install the unit so it receives the warmest air temperatures possible and that the cold air is not able to recirculate back into the unit.

Indoor Installation

• The unit may be able to be installed in an unventilated room exceeding 25m3 in volume.
• Venting of cold air is advised to prevent the air temperature dropping and lowering the efficiency of the unit.
• Think of the unit as a 3kW air conditioner for the effect it will have on a closed room.

TO COOL A ROOM
Install the unit so the outlet from the heat pump is blowing INTO the room. The room MUST have some form of air outlet otherwise the performance of the unit will suffer significantly.

TO MAINTAIN NORMAL ROOM TEMPERATURE
Install the unit so the outlet from the heat pump is blowing OUTSIDE the room. The room MUST have some form of air inlet otherwise the performance of the unit will suffer significantly.

Airflow Clearances

The Evo315-C must be installed with sufficient clearances to allow airflow to circulate through the unit, it is advised to keep a minimum gap between walls/fences etc of:

• 1000mm on the air inlet & outlet sides
• 300mm rear clearance
• 600mm overhead clearance

Without sufficient airflow, discharged cold air will recirculate into the unit and consequently lower the heating efficiency.

If the installation location does not comply with these suggested clearances, contact EvoHeat’s Tech Support to discuss possible solutions.

Cable Connection

The power cable for power supply of the unit is stored in the back of the unit. The unit requires an isolating switch as required by local laws. If the power cord is damaged, it must be replaced by a qualified electrician.

Filling the Tank

Open a hot water tap inside the house. Open the cold-water inlet valve into the Evo315-C to fill the tank. When water begins flowing out of the hot water tap inside the premises, turn off the hot water tap.

Initial Start-Up

PRE-INSPECTION
Check the water supply to the tank and pipe connections for possible leaks.

Wi-Fi Module Connection (Optional)

Note: If you do not have a Wi-Fi module to install, simply push the cord entirely behind the front panel.
The optional Wi-fi Control upgrade can be purchased to allow you to remotely control your EvoHeat hot water heat pump from your phone.
Newly installed units will have a small cable that protruding out from behind the front panel with a small waterproof cover.
If you are installing the Wi-Fi module, simply connect the cable of the Wi-Fi module to the one that protrudes.
Once the Wi-Fi module has been connected, ensure that the connection part of the cable is placed behind the front cover.
The module must be placed with the cord coming downwards to protect it from water.

Use of the P&T Valve

The P&T valve is used to prevent the temperature or pressure becoming too high inside the tank. When the temperature or pressure reaches the set value, the valve will open automatically to force the pressure or temperature to decrease

The handle of the safety valve should be tested once every six months to remove the calcium carbonate deposits and guarantee there is no blockage in the device. Take care to avoid burns as the temperature of the discharging water is very high.

Vent pipes should be thermally insulated to prevent safety risks caused by freezing pipes in winter.

P &T valve: Model: PTR-20, action temperature: 99˚C, action pressure:0.85MPa

WARNING: Failing to operate the relief valve easing gear at least once every six months may result in the water heater exploding. Continuous leakage of water from the valve may indicate a problem with the water heater.

Using the Overheating Protector

The overheating protector is used to turn the power off in an emergency or with power supply issues, preventing the water from being heated too high.

A thermal cut-out could indicate a possibly dangerous situation. Do not reset the thermal cutout until the unit has been serviced by a qualified technician. Contact EvoHeat for a service if this occurs before attempting to reset.

To return the unit to its normal operation status by resetting manually:

• To access the overheat protector, remove the front dark grey controller panel.
• Remove the 3 screws on the front panel and push the front cover upwards.
• Remove the remaining screws which cover the overheat protector panel.

Draining the Water Tank

1. Close the cold-water inlet valve into the Evo315-C.
2. Open a hot water tap inside the premises.
3. Undo the drain plug on the base of the unit to drain the water from the system.

The water from the hot water tap and the drain plug will be hot. Be careful of burns and scalds. Wear protective clothing.

Earthing Methodology

Maintenance

Your Evo315-C will operate most efficiently if regularly inspected as part of your home maintenance schedule.

MINOR ANNUAL MAINTENANCE
It is recommended that the minor maintenance be performed every 12 months by the dwelling occupant.

The minor maintenance includes:

• Operate the easing lever on the temperature pressure relief valve. It is very important you raise and lower the lever gently.
