Possible options for the outdoor unit
Remote outdoor sensor (RKRSC1)
By default the sensor inside the outdoor unit will be used to measure
the outdoor temperature.
As an option the remote outdoor sensor can be installed to measure
the outdoor temperature on another location (e.g. to avoid direct
sunlight) to have an improved system behaviour.
For installation instructions, see the installation manual of the remote
outdoor sensor.

Preparation
5.1
Overview: Preparation
This chapter describes what you have to do and know before going
on-site.
It contains information about:
▪ Preparing the installation site
▪ Preparing the water piping
▪ Preparing the electrical wiring
5.2
Preparing the installation site
Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit must be covered.
Choose an installation location with sufficient space for carrying the
unit in and out of the site.

INFORMATION
If shut-off valves are installed on the unit, provide a
minimum space of 400 mm at the air inlet side. If shut‑off
valves are NOT installed on the unit, provide a minimum
space of 250 mm.
The maximum allowable distance between outdoor unit and HPSU
monobloc tank is 10 m.
NOTICE
▪ Do NOT stack the units on each other.
▪ Do NOT hang the unit on a ceiling.
Strong winds (≥18 km/h) blowing against the outdoor unit’s air outlet
causes short circuit (suction of discharge air). This may result in:
▪ deterioration of the operational capacity;
▪ frequent frost acceleration in heating operation;
▪ disruption of operation due to decrease of low pressure or
increase of high pressure;
▪ a broken fan (if a strong wind blows continuously on the fan, it
may start rotating very fast, until it breaks).
It is recommended to install a baffle plate when the air outlet is
exposed to wind.
It is recommended to install the outdoor unit with the air inlet facing
the wall and NOT directly exposed to the wind.
