5. Installation
5.1 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.
5.2 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
Manual 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.
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.

5.3 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.
5.3.1 Indoor Installation
•The unit may be able to be installed in an unventilated room exceeding 25m3in 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
TO MAINTAIN NORMAL ROOM TEMPERATURE
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.
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.
5.4 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,

5.5 Cable Connection 5.6 Filling the Tank
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.
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.
5.7 Initial Start-Up
PRE-INSPECTION
Check the water supply to the tank and pipe connections for possible
leaks.
Check that the following devices are installed and operating correctly:
•Drainpipes
•P&T Valve
•Filter on inlet
•Water softening and pressure reducing devices if required.
Check that all power connections are secure before switching on.
Check that the installation space is adequate.
TRIAL OPERATION
Switch on the unit by using the
controller.
If any unusual noises occur, switch the
power off and consult your provider.
The parameters have been pre-set to
a temperature of 60 degrees. Check
that the unit is operating by looking for
an increase in water temperature over
time.

8.3 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: 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.
8.4 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:
a) To access the overheat protector, remove the front dark grey
controller panel.
b) Remove the 3 screws on the front panel and push the front
cover upwards.
c) Remove the remaining screws which cover the overheat
protector panel.
Remove the screws and open the cover
Press the red button to reset
8.5 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.
8.6 Earthing Methodology
The water from the hot water tap and the drain plug
will be hot. Be careful of burns and scalds. Wear
protective clothing.

9. 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. Exercise care to avoid any splashing of water, as water discharged from the drain line will be hot.
Stand clear of the drain lines point of discharge when operati
•Operate the easing level on the expansion control valve (if fitted). It is very important you raise and lower the
lever gently.
•Conduct a visual inspection of all plumbing and electrical connections.
•Check the condensate drain line to ensure it is not blocked.
•Check that air vents are not blocked or obstructed, and if necessary clean with a damp cloth or air blower.
•Conduct a general external clean of the unit with a damp cloth.
MAJOR FIVE-YEAR SERVICE
It is recommended a major five (5) year service be conducted on the Evo315-C.
Warning: Servicing of a water heater must only be carried out by qualified EvoHeat personnel.
Phone EvoHeat Service on 1300 859 933 for our closest Accredited Service Agent.
Note: The five-year service and routine replacement of any components such as the anode and relief valve(s) are not
included in the EvoHeat warranty. Only genuine replacement parts should be used on this water heater.
The major service includes the following actions:
•Replace the temperature limiting valve.
•Replace the temperature pressure relief valve.
•Inspect the anode and if required, replace the anode. If the anode is not replaced, it should be replaced within
three years of this service.
•Check the heating cycle of the unit.
•Visually check the unit for any potential problems.
•Inspect the plumbing and electrical all connections.
•Check the condensate on drain line to ensure it is not blocked.
Note: The water heater may need to be drained during this service. After the completion of the service, the water
heater will take some time to reheat the water. Depending upon the power supply connect on, hot water may not be
available until the next day.
