when it is properly connected to an efficient grounding system, done according to
electrical safety standards in force.
Do not operate the GAHP-AR if electrical or safety components have been
excluded, by-passed or do not function correctly.
If the above mentioned conditions have been satisfied, the installation procedure (done by
the qualified company) and the successive start-up (done by a Robur Corporation
authorized Technical Service Centre, "TAC") may begin.
The initial start-up of the GAHP-AR must only be done by a Robur Corporation
authorized Technical Service Centre (TAC) following the indications provided by
the manufacturer. The warranty of the GAHP-AR is effective only if validated by a
Robur Corporation "TAC".
In case of fault during installation and ignition with the smell of natural gas
If you smell gas:
•
Do not operate electrical devices near the GAHP-AR, such as telephones, multi-
meters or other devices that can create sparks.
•
Close the gas supply valve.
•
Shut off electrical power to the GAHP-AR.
•
Call a Qualified Service Engineer using a telephone that is not near the GAHP-AR.
In case of fault during installation and ignition without the smell of natural gas
In case of fault or poor functioning of the GAHP-AR without the escape of gas,
immediately shut it down using the appropriate control switch (see “ACTIVATION (AND
DEACTIVATION) OF THE APPLIANCE”, page 15); if the shutdown cycle begins, wait for
it to complete, which takes about 10 minutes; remove electrical power by shutting off the
main power switch and close the gas valve. If the shutdown cycle does not start due to an
occurring problem, directly shut off the electrical power and gas supplies.
Do not attempt any type of intervention or repair.
Perform these operations even if the cooling unit has not been used for a long period of
time, see the “PROLONGED PERIODS OF DISUSE” paragraph on page 24.
To ensure the correct functioning of the chiller and to prevent possible problems, it
should only be shut down using the control switch or through the Direct Digital
Controller (DDC) if mounted.
Avoid turning off the GAHP-AR by interrupting the electrical power supply upstream
of the control switch before this has been turned off and the shutdown cycle has
completed.
