•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.
•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.

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.

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 Evo150-1 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 Evo150-1 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:
•300mm on the air inlet side
•500mm on the air outlet side
•100mm overhead & rear 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.
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 Evo150-1 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: 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.
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 Evo150-1.
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 Evo150-1 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 operating the valve’s lever.
•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.
