REMKO RVS 60 H - Manual (Page 33)

The systems are equipped
with a phase sequence relay
which prevents the operation
of the controller if the phrase
sequence for the electric mains
connection is wrong.
The phrase sequence must be
corrected if the controller is
not activated during
commissioning.
NOTE
During manual bleeding, es-
caped glycol mixtures must be
disposed of separately.
NOTE
Additional checks
General checks
■
Checking that minimum clear-
ances are correct.
■ Check the outlet possibility of
the cooling and heating, for
the cold and hot water outlet
(indoor unit).
Electrical checks
■
Checking electrical connections
for correct phase sequencing.
■
Check that the operating
contact cooling mode/heating
mode works (option).
■
Check that the enabling contact
on / stand-by works (option).
Checking the medium cycle
■
Check the circulating pump for
free flow.
■
Check that all valves are open.
■
Check the medium cycle.
■
Set the circulation pump’s flow
volume.
Checking the cooling cycle
■
Checking the cooling cycle for
adequate oil/coolant.
■
Check the cooling cycle for
leaks.
Expansion vessel
■
The preliminary pressure for the
diaphragm expansion vessel must be
adjusted individually to the system
layout, the volume of the medium
and the installed position.
■
If necessary, change the installed.
For this, the manufacturer’s au-
thorisation is required.
■
For the cooling and heating
systems, the volume and the
preliminary pressure for the
diaphragm expansion vessel must
be adjusted to both operating
modes; integrate an additional
diaphragm expansion vessel in
the system if necessary.
Valve for hydronic balancing
■
The pressure in the pipe system
of the individual cold water
outlets can be adjusted at the
valves.
Safety valve
■
The safety valves must be
checked that they are working
correctly.
■
The drain line for the valves
are to be checked that they are
clear and leak tight.
■
If necessary, change the in-
stalled position.
For this, the manufacturer’s
authorisation is required.
