LRMEQ+LRLEQ3+4BY1
Air-cooled refrigeration condensing unit
4P500362-1A – 2018.09
18.1 Maintenance after a long stop
period
E.g., at the beginning of the season.
▪ Check and remove everything that might be blocking inlet and
outlet vents of the outdoor unit.
18.2 About the refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R410A
Global warming potential (GWP) value: 2087.5
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes CO
2
equivalent) is used to determine the maintenance intervals.
Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.
WARNING
The refrigerant in the system is safe and normally does not
leak. If the refrigerant leaks in the room, contact with a fire
of a burner, a heater or a cooker may result in a harmful
gas.
Turn off any combustible heating devices, ventilate the
room and contact the dealer where you purchased the unit.
Do not use the system until a service person confirms that
the portion where the refrigerant leaks is repaired.
18.3 After-sales service and warranty
18.3.1 Warranty period
▪ This product includes a warranty card that was filled in by the
dealer at the time of installation. The completed card has to be
checked by the customer and stored carefully.
▪ If repairs to the product are necessary within the warranty period,
contact your dealer and keep the warranty card at hand.
18.3.2 Recommended maintenance and
inspection
Since dust collects when using the unit for several years,
performance of the unit will deteriorate to some extent. As taking
apart and cleaning interiors of units requires technical expertise and
in order to ensure the best possible maintenance of your units, we
recommend to enter into a maintenance and inspection contract on
top of normal maintenance activities. Our network of dealers has
access to a permanent stock of essential components in order to
keep your unit in operation as long as possible. Contact your dealer
for more information.
When asking your dealer for an intervention, always state:
▪ The complete model name of the unit.
▪ The manufacturing number (stated on the nameplate of the unit).
▪ The installation date.
▪ The symptoms or malfunction, and details of the defect.
WARNING
▪ Do not modify, disassemble, remove, reinstall or repair
the unit yourself as incorrect dismantling or installation
may cause an electric shock or fire. Contact your
dealer.
▪ In case of accidental refrigerant leaks, make sure there
are no naked flames. The refrigerant itself is entirely
safe, non-toxic and non-combustible, but it will
generate toxic gas when it accidentally leaks into a
room where combustible air from fan heaters, gas
cookers, etc. is present. Always have qualified service
personnel confirm that the point of leakage has been
repaired or corrected before resuming operation.
19 Troubleshooting
If system malfunctions are likely to degrade the articles in the room/
showcase, you can ask your installer to install an alarm (example:
lamp). For more information, contact your installer.
If one of the following malfunctions occur, take the measures shown
below and contact your dealer.
WARNING
Stop operation and shut off the power if anything
unusual occurs (burning smells etc.).
Leaving the unit running under such circumstances may
cause breakage, electric shock or fire. Contact your dealer.
The system MUST be repaired by a qualified service person.
Malfunction Measure
If a safety device such as a fuse, a
breaker or an earth leakage breaker
frequently actuates or the ON/OFF
switch does not properly work.
Turn off the main power
switch.
If water leaks from the unit. Stop the operation.
The operation switch does not work
well.
Turn off the power.
If the system does NOT properly operate except for the above
mentioned cases and none of the above mentioned malfunctions is
evident, investigate the system according to the following
procedures.
Malfunction Measure
If the system does not
operate at all.
▪ Check if there is no power failure. Wait
until power is restored. If power failure
occurs during operation, the system
automatically restarts immediately after
power is restored.
▪ Check if no fuse has blown or breaker is
activated. Change the fuse or reset the
breaker if necessary.
The system stops
immediately after
starting operation.
▪ Check if air inlet or outlet of outdoor or
indoor unit is not blocked by obstacles.
Remove any obstacles and make sure
the air can flow freely.
