Combining units and options

4.3.1

Possible options for the outdoor unit

Refrigerant branch kit

When connecting multiple indoor units to the outdoor unit, you need
one or more refrigerant branch kits. The outdoor‑indoor combination
determines which and how many refrigerant branch kits to use.

Demand adaptor kit (SB.KRP58M52)

▪ Includes the additional mounting plate (EKMKSA2)

▪ Can be used for the following:

▪ Low noise: To lower the operation sound of the outdoor unit.

▪ I-demand  function:  To  limit  the  power  consumption  from  the

system  (example:  budget  control,  limit  power  consumption
during peak moments…).

▪ For  installation  instructions,  see  the  installation  manual  of  the

demand adaptor kit.

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 refrigerant piping

▪ Preparing the electrical wiring

5.2

Preparing 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 the installation location with sufficient place for carrying the
unit in and out of the site.

WARNING

The  appliance  shall  be  stored  in  a  room  without
continuously  operating  ignition  sources  (example:  open
flames, an operating gas appliance or an operating electric
heater).

5.2.1
