Function Test - CLIVET CRISTALLO MM2-Y 27M Handbuch Für Installation

Starting up the system
3.1.1 Refrigerant charge
The unit is factory pre-charged with a sufficient quantity
of refrigerant for pipe length up to 5 metres.
Unit
Refrigerant
kg 0,55
pre-charge
If the length of the pipes is longer than 5 metres,
an additional charge of refrigerant is required.
For each additional metre, the following quantity of
refrigerant must be added:
Unit
Additional charge g/m
The refrigerant must be charged through the low pressure
valve of the outdoor unit.
d
IT IS PROHIBITED TO
mix different types of refrigerant
FULL REFRIGERANT RECHARGE
If a full charge of the refrigerant is required (e.g. after
moving / replacing the unit or after a leakage) the total
refrigerant charge will be the sum of the factory refrigerant
pre-charge + the additional charge in the case of a pipe
length of more than 5 meters.
3.2 Electrical dispersion and gas
leakage control
3.2.1 Electrical safety controls
After installation, check that all electrical cables are
installed according to national and local codes and
according to the instructions in the Installation Manual.
BEFORE THE OPERATIONAL TEST
Checking earthing
Measure the earthing resistance with visual detection
and a specific tester. The earthing resistance must be
less than 0.1Ω.

DURING THE OPERATIONAL TEST
Electrical dispersion control
During the operational test, use an electrode and
multimeter to conduct a complete electrical leakage test.
If an electrical leakage is detected, turn the unit off
immediately and consult a qualified electrician to identify
and resolve the cause of the problem.
f
ATTENTION ELECTRIC DANGER
All electrical connections must be done by a
licensed electrician according to the provisions
of national and local electrical codes.
3.2.2 Checking for gas leaks
There are two different methods of checking gas leaks.
Method with soap and water
Using a soft brush, apply soapy water or liquid detergent to
all pipe joints of the indoor and outdoor units. The bubble
formation will indicate a leak.
Leak detector method
If using a leak detector, follow the instructions in the user
manual of the device.
AFTER CHECKING FOR GAS LEAKS
After checking that the pipe joints are NOT leaking,
re-apply the valve assembly cover to the outdoor unit.

Function test

3.3.1 Preliminary checks
The function test shall be carried out only after the
following procedures have been completed:
– Electrical safety checks - Check that the electrical
system is safe and functioning properly
– Check for gas leaks - Check all joints with
countersunk nuts and check the system for leaks
– Check that the valves on the gas and liquid side
(high and low pressure) are fully open
3.3.2 Operating test instructions
The function test shall be carried out for at least
30 minutes.
1 Connect the unit to the power mains.
2 Press the ON/OFF button on the remote control to
turn it on.
3 Press the MODE button to scroll through the following
functions, one at a time:
