7.1 Maintenance after Unit has been Shut Down
for a Long Period
For example, in early summer or winter.
▪ Check and remove all objects that may clog the air inlets and outlets
of the indoor and outdoor units.
▪ Clean the air filter and external shell of the unit. Please contact the
installation or maintenance personnel. The installation/operation
manual of the indoor unit includes maintenance tips and cleaning
procedures. Make sure that the clean air filter is installed in its
original position.
▪ Turn on the main power supply 12 hours before this unit is operated
in order to ensure that the unit runs smoothly. The user interface is
displayed once the power is turned on.
7.2 Maintenance Before Unit is Shut Down for
a Long Period
For example, at the end of winter and summer.
▪ Run the indoor unit in the fan mode for about half a day to dry the
internal parts of the unit.
▪ Turn off the power supply.
▪ Clean the air filter and external shell of the unit. Please contact the
installation or maintenance personnel to clean the air filter and
external shell of the indoor unit. The installation/operation manual of
the specialized indoor unit includes maintenance tips and cleaning
procedures. Make sure that the clean air filter is installed in its
original position.
7.3 About the Refrigerant
This product contains fluorinated greenhouse gases as stipulated
in the Kyoto Protocol. Do not discharge the gas into the atmosphere.
Based on the applicable law, the refrigerant must be checked regularly
for leakages. Please contact
more information.
Warning
The refrigerant in the air conditioner is relatively safer, and usually
does not leak. If the refrigerant leaks, and comes in contact with
burning objects in the room, it will produce harmful gases. Shut
down any flammable heating device, ventilate the room and
contact the agent
Do not use the air conditioner again until the maintenance
personnel has confirmed that the refrigerant leakage has been
sufficiently resolved.
Warning
The partial units shall only be connected to an appliance
suitable for the same refrigerant.
This unit is a partial unit air conditioner, complying with partial
unit requirements of this International Standard, and must
only be connected to other units that have been confirmed as
complying to corresponding partial unit requirements of this
International Standard.
Important information for the refrigerant
7.3.1
This product has the fluorinated gas, it is forbidden to release to air.
Refrigerant type: R410A/8Kg
Volume of GWP: 2088; tonnes CO2 equivalent
GWP=Global Warming Potential
the installation personnel
of the unit immediately.
Attention:
Frequency of Refrigerant Leak Checks
▪
For equipment that contains fluorinated greenhouse gases in
quantities of 5 tonnes of CO2 equivalent or more,but of less than 50
tonnes of CO2 equipment,at least every 12 months, or where a
leakage detection system is installed, at least every 24 months.
▪
For equipment that contains fluorinated greenhouse gases in
quantities of 50 tonnes of CO2 equivalent or more,but of less than
500 tonnes of CO2 equipment,at least every six months, or where a
leakage detection system is installed, at least every 12 months.
▪
For equipment that contains fluorinated greenhouse gases in
quantities of 500 tonnes of CO2 equivalent or more,at least every
three months ,or
at least every six months.
▪
Non-hermetically
greenhouse gases shall only be sold to the end user where evidence
is provide that the installation is to be carried out by an undertaking
certified person.
▪
Only certificated person is allowed to do installation, operation and
maintenance.
7.4 After-sales Service
7.4.1 Recommended maintenance and inspection
As the use of the unit for many years will eventually lead to a dust
layer, the performance of the unit will degenerate to a certain extent.
As professional skills are needed to dismantle and clean the unit, and
for the optimal maintenance effects of this unit, please contact your
agent for more details.
When you request the agent for assistance, please remember to state:
for
▪ Complete model name of the air conditioner.
▪ Date of installation.
▪ Details on the fault symptoms or errors, and any defects.
Warning
▪ Do not attempt to modify, dismantle, remove, reinstall or repair
this unit, as the improper dismantling or installation may result
in electric shock or fire. Please contact the agent.
▪ If the refrigerant accidentally leaks, make sure that there is no
fire around the unit. The refrigerant itself is completely safe,
non-toxic and non-flammable, but it will produce toxic gases
when it accidentally leaks and comes in contact with flammable
substances generated by existing heaters, and burning devices
in the room. You must get a qualified maintenance personnel to
verify that the point of leakage has been repaired or rectified
before you restore the operations of the unit.
7.4.3 Shorter maintenance and replacement cycle
In the following
"replacement cycle" may be shortened.
The unit is used in the following situations:
▪ Temperature and humidity fluctuations are outside the normal
ranges.
▪ Large power fluctuations (voltage, frequency, waveform distortion
etc.) (must not use the unit if the power fluctuations exceed the
allowed range).
▪ Frequent collisions and vibrations.
▪ The air may contain dust, salt, harmful gas or oil such as sulphite
and hydrogen sulphide.
▪ Frequent on and off of unit or operating time is too long (in places
where the air conditioning is on for 24 hours a day).
