1. I
1.1. General information
Thank you for purchasing this unit.
The outdoor unit is the air to water Daikin ERSQ or ERRQ heat
pump.
ERRQ units include special equipment (insulation, heater sheet, ...)
to ensure good operation in areas where low ambient temperature
can occur together with high humidity conditions. In such conditions
the ERSQ models may experience problems with severe ice build up
on the aircooled coil. In case such conditions are expected, the
ERRQ must be installed instead. These models contain counter-
measures (insulation, heater sheet, ...) to prevent freeze up.
NOTE
Possible options
For ERSQ models an optional bottom plate heater kit EKBPHT16A
can be connected to the outdoor unit. Refer to the installation manual
of the bottom plate heater kit for further details.

1.2. Scope of this manual
