▪ The foundation must be strong enough to bear the weight of the unit. Take the
weight of the unit with a domestic hot water tank full of water into account.
Make sure, in the event of a water leak, water cannot cause any damage to the
installation space and surroundings.
Do NOT install the unit in places such as:
▪ In places where a mineral oil mist, spray or vapour may be present in the
atmosphere. Plastic parts may deteriorate and fall off or cause water leakage.
▪ Sound sensitive areas (e.g. near a bedroom), so that the operation noise will
cause no trouble.
▪ In places with high humidity (max. RH=85%), for example a bathroom.
▪ In places where frost is possible. Ambient temperature around the indoor unit
must be >5°C.
Special requirements for R32
The indoor 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 refrigerant cycle parts.
▪
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 and are executed ONLY by authorised
persons.
At certain times, you have to open the unit. Example:
▪ When connecting the electrical wiring
▪ When maintaining or servicing the unit
DANGER: RISK OF ELECTROCUTION
Do NOT leave the unit unattended when the service cover is removed.
