▪ Choosing between glycol and freeze protection valves
▪ Installing the bottom plate heater
3.2.1
Glycol or freeze protection valves
Frost can damage the system. To prevent the hydraulic components
from freezing, the software is equipped with special frost protection
functions, that include the activation of pump in case of low
temperatures.
However, in case of a power failure, these functions cannot
guarantee protection.
Do one of the following to protect the water circuit against freezing:
▪ Add glycol to the water. Glycol lowers the freezing point of the
water.
▪ Install freeze protection valves. Freeze protection valves drain the
water from the system before it can freeze.
NOTICE
If you add glycol to the water, do NOT install freeze
protection valves. Possible consequence: Glycol leaking
out of the freeze protection valves.
INFORMATION
For more information about glycol and freeze protection
valves, see
"5.3.3 To protect the water circuit against
freezing" [ 4 13].
3.2.2
Bottom plate heater
To prevent freeze-up of the bottom plate you can install the optional
bottom plate heater. In certain circumstances this is required.
Bottom plate heater (EKBPHT04JH)
▪ Prevents freeze-up of the bottom plate.
▪ Required in areas with ambient temperature <–5°C and high
relative humidity for at least 3 consecutive days.
▪ For installation instructions, see the installation manual of the
bottom plate heater.
NOTICE
▪ If you install the bottom plate heater, you may lower the
operation range of the heat pump to Ta≥–14°C using
field setting [8-0E]=–14°C.
▪ If you do not install the bottom plate heater, keep
[8-0E]=–5°C.

NOTICE
The height of the wall on the outlet side of the outdoor unit
MUST be ≤1200 mm.
The outdoor unit is designed for outdoor installation only, and for the
following ambient temperatures:
Space heating operation
Domestic hot water production
Special requirements for R32
The outdoor unit contains an internal refrigerant circuit (R32), but
you do NOT have to do any refrigerant field piping, or refrigerant
charging.
The total refrigerant charge in the system is ≤1.842 kg, so the
system is NOT subjected to any requirements to the installation
room. However, mind the following requirements and precautions:
WARNING
▪ Do NOT pierce or burn.
▪ Do NOT use means to accelerate the defrosting
process or to clean the equipment, other than those
recommended by the manufacturer.
▪ Be aware that R32 refrigerant does NOT contain an
odour.
WARNING
The appliance shall be stored so as to prevent mechanical
damage and in a well-ventilated room without continuously
operating ignition sources (example: open flames, an
operating gas appliance or an operating electric heater).
WARNING
Make sure installation, servicing, maintenance and repair
comply with instructions from Daikin and with applicable
legislation (for example national gas regulation) and are
executed only by authorised persons.
4.1.2
Additional installation site requirements
of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.
