Preparing the unit Where to install the unit
When the unit is delivered there is a blue cover over the coil, please
remove it, the remote controller is in a box at the back off the unit
Remove the right hand front cover of the unit to gain access.
To gain access to the wiring, you will need to remove the 2 x 13mm
bolts at the front to get the cover off, don’t loose them they MUST go
back in.
On the larger 8-12-14kw units, the compressor has a plate which has
to be removed prior to installation, see above. Do not remove the
metal frame the unit is bolted to, it is structural.

Installing the Outdoor Unit (Boiler)
Position the outdoor unit so that the air flows into an open area, where there are no plants and animals. If the unit
is to be installed within a mile of the sea you need to have the unit coated using Blygold, ask us for details. If you are
applying for RHI and going through MCS you need to make sure the system meets MIS020.
Install the outdoor unit on a flat, stable surface, it needs to be securely mounted at least 100mm off the ground. You
can use rubber feet under the unit if you want but its not essential.
The unit must have adequate drainage, it can produce up to 6 L / hour of condensate. If you are installing the unit at
height you can install a drain pan under the unit but its best to let the unit drain into the ground.

300mm to the rear of the unit and 1500mm to the front of the
unit.

How it’s going to work Running the unit for the first time
Space Heating
The heat pump has its own inbuilt weather compensation system,
it will look for a heating run signal from an external thermostat or
under floor heating system (field supplied). The unit sends out 240V
AC on terminal 15 when you send it back on terminal 3 the unit
runs in heating mode. This will come from your underfloor heating
system or your heating zone valves after the header.
Before power up
Filling it with water
Connect the water supply to the fill valve and open the valve.
Make sure the automatic air vent is open, its in the outdoor unit
inside a rubber cover top right hand side of the unit .
Fill with water pressure of approximately 2.0 bar. Remove air in
the circuit as much as possible using the air purge valves. Air in the
water circuit will cause flow errors EO and E8
Setting up the cylinder immersion heater
To insure the unit has adequate legionella protection the immersion
heater will run for 1 hour a week controlled by an external time
clock. It will run the immersion heater make sure the internal
thermostat on the immersion is set as high as possible 60°C.
Turn all thermostats down and underfloor heating off, before you
power up the heat pump.
Power up the unit and look at the
display on the outdoor unit PCB.
In the middle of the main PCB inside the right hand casing there
is a red 3 digit display, it will light up and show the current water
temperature. If nothing is displayed check the power supply to the
unit. Once it is lit up check the remote controller.
On the screen of the remote controller it will count to 100, then it
will ask you which language to use, select EN press OK. If you wait 60
seconds it will just select English as default.
If the error code E2 is displayed on the controller check the wiring
between the remote controller and unit. Redo the wiring and reset
the power.
Domestic water heating
The target tank water temperature is set on the Midea remote
controller. The Midea unit will decide when to go into HW mode it
will stop Pump Po (heating pump) the 3 port valve SV1 will power
open.
The AVV is protected
with a rubber cover.
Make sure the AAV is
open before filling the
unit.

DO NOT SKIP THIS SECTION
The unit is delivered as a completely blank slate, it does not know
you want to use a hot water cylinder or that you are using an
external heating run signal. So if you just switch it on and leave you
will be back to do the job properly.
The controller will look like the image to the right.
• Press and hold the UNLOCK button for 3 seconds
• Press MENU press 8 times to SERVICEMAN, press OK
• Enter password 234 press OK
• Go to DHW MODE setting, press OK
• IN DHW mode press then change it to YES press OK
• Go to DISINFECT press then to NON press OK (legionella is
