General information
This installation manual concerns Daikin Altherma air to water
inverter heat pump units of the Daikin EMRQ series.
These units are intended for outdoor installation and aimed for
apartment or other multi user buildings.
The unit is designed to produce domestic hot water and is not
designed for space heating.
These units have heating capacities ranging from 22.4 to 45 kW.
The outdoor unit is designed to work in domestic hot water mode at
ambient temperatures from –20°C to 35.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.
When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.
NOTE
Design of the system must not be done at tempera-
tures below –15°C.
