REMKO RXS xxx H - Manual (Page 17)

■
Functional test of the indoor
unit and all program sequences.
■
Check of the surface
temperature of the suction pipe
and determination of vaporiser
overheating.
To measure the temperature,
hold the thermometer to the
suction line and subtract the
boiling point temperature.
reading on the pressure
gauge from the measured
temperature.
■
Record the measured
temperatures in the
commissioning report.
Functional test for cooling mode
1. Remove the protective caps
from the valves.
2. Begin the commissioning
process by briefly opening the
stop valves on the outdoor
component until the pressure
gauge indicates a pressure of
approx. 2 bar.
3. Use leak detection spray or
suitable devices to check that
all the connections are tight. If
no leaks are found, fully open
the stop valves by turning them
anti-clockwise using a spanner.
If leaks were found, draw off
the refrigerant and rework
the defective connection. It is
imperative that the vacuum
creation and drying steps are
repeated!
4. Switch off the main circuit
breaker or remove the fuse
(provided by the customer).
NOTE
Due to the turn on delay, the
compressor will start up a few
minutes later.
7. Check the correct function
and settings of all regulation,
control and safety devices
during the test run.
8. Check the control system in the
indoor unit using the functions
described in the manual.
Timer, temperature settings and
all mode settings.
9. Check the overheating,
outdoor, indoor, outlet and
vaporisation temperatures and
record the measured values in
the commissioning report.
10. Remove the pressure gauge.
5. Set the target temperature
on the indoor unit using the
remote control. This should be
set to a value lower than the
room temperature.
6. Switch the indoor unit to
cooling mode.
Functional test for
heating mode.
1. Switch the supply voltage on.
2. Use the remote control to
switch on the unit and select
the heating mode, maximum
fan speed and highest target
temperature.
3. Measure and record all
the required values in the
commissioning report and
check the safety functions.
4. Check the control system for
the unit using the functions
described in the chapter
"Operation".
Timer, temperature setting, fan
speeds.
Check that the stop valves
and valve caps are tight after
carrying out any work on the
refrigerant circuit. If necessary,
use appropriate sealant
products.
NOTE
Final tasks
■
Use the remote control to set
the target temperature to the
required value.
■
Re-fit all the dismantled parts.
■
Familiarize the operator with
the system.
