5.3 Location of Installation
The Evo270-1 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 25m
3
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
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 Evo270-1 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 Evo270-1 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.
