Connecting the heating system
Indoor SHK 200S units can cooperate with external
units of Split type. Compatible heat pumps METRO -
THERM SPLIT include:
An external heat source, eg a gas or oil boiler, can
be connected to the back of the SHK 200S / SHK
200S-6, removing the access block to the connection
sockets (picture below). Scheme on page 11.
The SHK 200S / SHK 200S-6 pmodule is equipped with
a condensate hose in the heat exchanger section. The
hose drains all condensate away from the device to
minimize the risk of damage. If necessary, the hose can
be extended.

Pipe connections of the heating system are to be
made at the top.
• All the required protections and cut-off valves
must be installed as close to the SHK 200S / SHK
200S-6 module as possible.
• Where necessary, install the vents.
• Safety valve with a nanometer at the central heat-
ing circuit and the safety valve at the hot water
system must be installed on relevant conductors
XL 11 and XL 4. In order to prevent air sockets,
the overflow pipe must be slanted at the entire
length from the safety valve, and must be se-
cured against freezing.
• When connecting to the installation where all
heaters have been equipped with thermostat
valves, install a discharge valve or remove sever-
al thermostats to assure appropriate flow.

IMPORTANT
The term “heating system”, as used in this installation
and operation manual, shall mean the heating or cool-
ing system supplied with a hot or cold medium from
the SHK 200S / SHK 200S-6 module for heating or
cooling purposes.

cessories to be used with SHK 200S / SHK 200S-6.
CAUTION
Suitable safety valve must be installed directly on the
cold water supply line to the hot water tank. Safety
valve will protect against excessive increase of pres-
sure.
Refrigerant pipes must be installed between the external
module METROAIR L and SHK 200S / SHK 200S-6 .
The installation must be executed according to the
applicable standards and directives.
Limitations
• Maximum pipe length, L6, L8, L12 is L=30 m.
• Maximum height difference (H): ±7 m.
Connecting refrigerant pipes
(not supplied)
CAUTION
The outdoor unit, factory-filled with refrigerant, enables
the use of refrigerant pipes (dimension L) between the
outdoor unit and the indoor unit measured with a length
of L = 15m. The maximum permissible length of the re -
frigerant pipes can be 30m, but this requires topping up
the installation with a refrigerant.
