ENERAL SAFETY PRECAUTIONS
The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.
Do not touch any switch with wet fingers. Touching a switch
with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.
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.
WARNING
■
Never

refrigerant. This could result in severe wounds caused
by frostbite.
■
Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the
refrigerant pipes. To avoid injury, give the pipes time to
return to normal temperature or, if you must touch
them, be sure to wear proper gloves.
CAUTION
Do not rinse the unit. This may cause electric shocks or
fire.

3.1. This manual
This manual describes how to start up and switch off the unit, set
parameters and configure the schedule timer by means of the
controller, maintain the unit and solve operational problems.
3.2. General information
Thank you for purchasing this indoor unit.
The unit is the indoor part of the air to water ERHQ or ERLQ heat
pumps. These units are designed for floor standing indoor
installation. The units can be combined with Daikin fan coil units, floor
heating applications, low temperature radiators, Daikin domestic
water heating applications and solar kit for domestic hot water
applications.
Heating/cooling units and heating only units
The unit range consists of two main versions: a heating/cooling
(EKHVX) version and a heating only (EKHVH) version.
Both versions are delivered with an integrated backup heater for
additional heating capacity during cold outdoor temperatures. The
backup heater also serves as a backup in case of malfunctioning of
the outdoor unit. The backup heater models are available for a
heating capacity of 6 and 9 kW, and – depending on the heating
capacity – for three different power supply specifications.
