REMKO ATY 260 - Manual (Page 27)

Start up
After all components are
connected and tested, the system
can be put into operation. To
ensure proper function, a function
test should be made to recognize
any irregularities during operation
of the units before transfer to the
client.
Function test and test run
Check the following points.
■ Leak tightness of refrigerant
lines.
■ Even run of compressor and
fan.
■ Discharge of cold air on the
interior unit and heated air on
the exterior unit during cooling
operation.
■ Function test of the interior unit
and all program runs.
■ Check of the surface
temperature of the suction
line and determination of
evaporator 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.
■ Documentation of the
measured temperatures in the
start up protocol.
Function test of Cooling
operating mode
1. Remove the caps on the valves.
2. Start operation by opening
the blocking valves of the
exterior unit momentarily until
the pressure gauge shows a
pressure of approx. 2 bar. .
3. Check all connections for leaks
with leak detection spray and
suitable leak detectors.
4. If not leaks are found, open the
blocking valves by turning them
in counterclockwise direction
with a hexagon wrench to the
stop. If leaks were found, draw
off the refrigerant and rework
the defective connection. In
this case, a new vacuum and
drying procedure is imperatively
required!
5. Turn the main switch on the
building or the fuse on.
6. Turn the unit on via the remote
control and select the cooling
mode, maximum fan speed and
lowest nominal temperature.
7. Measure all required values,
record them in the start up
protocol and check the safety
functions.
8. Check the unit control with
the functions described in
chapter „Operation“.
Timer, temperature setting, fan
speed and change between air
circulation or dehumidification
mode.
9. Check the function of the
condensation line by pouring
distilled water into the
condensation pan.
To do so, use a spout to guide
the water into the condensation
pan.
10. Switch the interior unit to
cooling mode.
11. Check all regulating, control
and safety devices for function
and correct adjustment during
the test run.
12. Check the control of the
interior unit with the functions
described in the operating
instructions
(Timer, temperature
adjustments and all mode
settings).
13. Measure the overheating,
external, internal, discharge and
evaporator temperatures and
record the test data in the start
up protocol.
14. Remove the pressure gauge
and install the caps.
The start up may only be
made by especially trained
technicians and must be
documented accordingly.
NOTE
Due to the turn on delay, the
compressor will start up a few
minutes later.
NOTE
Then check the blocking valves
for leaks.
NOTE
Final tasks
■ Reinstall all parts which were
removed.
■ Familiarize the operator with
the system.
