Commissioning - REMKO KWL 130 Operation Manual

If necessary, change the installa-
■
tion site. For this, the manufac-
turer's authorisation is required.
For cooling and heating sys-
■
tems, the volume and the
preliminary pressure for the dia-
phragm expansion vessel must
be adjusted to both operating
modes; integrate an additional
diaphragm expansion vessel in
the system if necessary.
Valves for hydronic balancing
The calculated excess pressure
■
in the pipe network layout at
the individual cold water outlets
must be adjusted in the pipe leg
regulating valves.
Safety valve
The safety valves and their cor-
■
rect function must be checked.
The drain line for the valves are
■
to be checked for function and
leak tightness.
If necessary, change the in-
■
stallation site. For this, the
manufacturer's authorisation is
required.
Additional checks
General checks
Checking that minimum clear-
■
ances are correct.
Check the outlet possibility of
■
cooling and heating capac-
ity over the cold or hot water
outlet (indoor unit).
Electrical checks
Checking electrical connections
■
for correct phase sequencing.
Function check of the cooling
■
mode/heating mode enable
(option).
Function check of the enable
■
mode / Stand-By (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.
NOTE
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.
Commissioning
NOTE
Commissioning should only be
Carried out by trained person-
nel and after certification to be
documented.
Observe the manuals for the
■
unit and all other components
when commissioning the entire
system.
Working test for cooling
mode
1. Switch the power supply on.
2. Open all shut-off valves if
necessary.
3. Switch the system and the cor-
responding circulating pump on
to the highest stage.
The outlet temperature must lie
between +4 and +18°C.
4. Switch the unit on and select
the cooling operating mode.
If the return temperature is
warmer than the setting, the
compressor display will blink
and the compressor will begin
to work after approx. 3 to 5
minutes.
5. Please note that the supply
temperature at the nominal
medium flow lies approx. 5 K
below the return temperature.
- If the supply temperature falls
below the factory setting of
4°C, a fault signal is triggers. If
this is the case, a higher target
temperature must be selected.
If the spread is too great or too
small, the medium flow must
be checked.
6. Measure and record all the
required values in the commis-
sioning report and check the
safety functions.
7. Check the system control using
the functions described in the
"Operation" chapter.
