Decommissioning, Dismantling and Disposal
1 - Safety
2 - Unit packaging
Installation and maintenance of this air conditioning system
should only be carried out by trained and qualified personnel.
Regular maintenance operations such as cleaning the coils and
air filters must be performed to keep the units in proper opera-
ting condition.
CAUTION
Before undertaking any work on the unit, make sure that the
power supply has been disconnected.
ELECTRICAL CONNECTIONS
All electrical wiring and connections must comply with applicable
local standards.
GENERAL PRECAUTIONS
Check that the power supply available agrees with nameplate
voltage.
Use adequate line protection.
The unit must be grounded.
Each unit is shipped with a Technical Guide.
The decorative front panel is removed for shipping and is packed
separate to protect it from any eventual transport damage.
Transport packing must removed before putting the window unit
in to service.
WARNING
Before initial start-up, remove the packing wedge
from the fan on YO 12-19-24 units.

5 - Installation
Unit installation entails :
- preparation of the masonry
- physical unit installation
- connection of the unit to an earthed mains outlet.
5.1 - Unit clearances
A minimum of clearance is necessary around the units to ensu-
re proper air circulation and easy access for maintenance.
Clearance required for units
Preparation of the masonry :
Create an opening in the outer wall to suit the external dimen-
sions of the window unit.
Physical unit installation :
- Remove the filter from the unit.
- Remove the front panel.
- Slide the unit out of its casing.
- Place the unit casing in the opening in the wall. Drill holes in
the casing to suit the thickness of the wall to enable the casing
to be fixed in the opening with screws and wall plugs (see dia-
gram below).
- Install a bracket (B) under the outdoor part of the unit to pro-
vide additional support if necessary.
- Fit the unit into its casing with a 1 or 2° downward slope
towards the outside. This will facilitate evacuation of conden-
sates.
Note : The air inlet grille must be outside.
Note : If the wall is particularly thick, make cut-aways on the
outside of the hole to enable proper air circulation.

6 - Condensat drainage
The fan propeller on the outdoor side of the unit has a lip at its
outer edge that projects condensates onto the condenser coil.
Heat produced by the coil evaporates the water. This increases
cooling and heating performances and eliminates the need to
install a condensate evacuation line (operating limit : 85 to 90%
humidity level).
Install the overflow on YO 12-19-24 units.
7 - User guide
1 - Fan speed selection
The unit can be operated in ventilation only mode (i.e. without
heating or cooling). Use the fan selector settings to operate.
For air circulation in the Heating or Cooling modes, set the fan
speed selector to I (low speed), II (medium speed), III (high
speed).
Blue lines correspond to operation in cooling mode, red lines
correspond to operation in heating mode.
2 - Mode selection (on WSH models only)
You may select either Heating or Cooling mode or the Ventilation
only mode.
3 - Thermostat
Adjust the thermostat to the setting that provides the highest
level of comfort heating or cooling. Higher numbers provide
lower room temperatures, lower numbers provide higher room
temperatures.
To reduce the temperature in the conditioned space (cooling
mode), turn the thermostat button clockwise.
To increase the temperature in the conditioned space (heating
mode), turn the thermostat button counter-clockwise.
4 - Air-Sweep Mode
When the Air Sweep mode is activated, the air flow is automati-
cally swept from left to right. If you want the air to be blown in a
particular direction, simply switch off air sweep just before it
reaches that position.
For vertical adjustment, move the horizontal deflectors manually.
5 - Ventilation
The unit either recycles indoor air (closed position) or exhausts
air outdoors (open position). Use the closed position when a
substantial amount of cooling is required. The closed position
can also be used to recirculate indoor air when using the
Ventilation Only mode. The closed position should be used to
obtain maximum heating on the heating/cooling model.
The open position enables removal of stale air from the room by
exhausting it outdoors. Fresh outdoor air is drawn into the room
through the normal air passages found in most buildings.
Stale air extraction damper closed position.
Stale air extraction damper open position.
6 - "Compressor" LED
This only concerns YO-YM 12-19-24 models fitted with this option :
the LED lights up when the compressor is operating.
7 - Stopping the unit
To stop the unit, set the selector to the “O” position

8 - Maintenance
9 - Trouble-shooting Guide
The units are designed to operate for long periods of time with a minimum of maintenance. However, the following operations must be
performed regularly.
COMPONENT MAINTENANCE OPERATIONS RECOMMENDED FREQUENCY
Air filter 1 - Clean with a vacuum cleaner or tap gently then Every month or more
wash in warm water (40°C) with a mild detergent. often if necessary.
2 - Rinse and dry before replacing on unit.
3 - Never use petrol, alcohol or any other chemical
product.
Unit casing 1 - Remove dust from the front panel with a soft duster Every month or more
or wipe a damp cloth with a mild soap solution. often if necessary.
2 - Never use petrol, alcohol or any other chemical
product.
Drain pan and 1 - Clean and check for obstructions. Each season before start up.
evacuation piping
Indoor / outdoor coils 1 - Check condition and remove dust from between Each season before start up.
coil fins.
Compressor 1 - No maintenance required.
ALL OTHER SERVICE AND MAINTENANCE OPERATIONS MUST BE PERFORMED
BY TRAINED AND QUALIFIED PERSONNEL APPROVED BY THE SUPPLIER
PROBLEM
A. The air conditioner does not operate
B. The air conditioner operates but
produces no cooling
C. Evaporator frosted
D. No heating
PROBABLE CAUSE AND REMEDY
1. Check that the unit is plugged in and that the circuit is not overloaded by
other electrical appliances.
2. Check fuses and /or circuit breaker and make sure that power is getting to
the unit.
3. If the fuse has been changed and it blows when the unit is restarted, or if the
circuit breaker cuts out immediately after it has been reset, do not hesitate
to contact your approved service centre.
1. Make sure that the thermostat is set to the right position for cooling.
2. Make sure that there are no obstacles in front of the unit that might impede
proper air circulation.
3. Make sure that the horizontal dampers open correctly.
4. Remove the decorative front panel and check that the thermostat bulb does
not touch the coil fins since this can cause compressor short-cycling.
5. Make sure that the filter is clean
6. Check that the evaporator coil is not frosted up
1. Make sure that the filter is clean. Wash with water if necessary.
2. To clear frost from the coil, place the selector at the Ventilation Only position.
3. Make sure that all the frost has been cleared from the coil before resuming
normal operation.
1. Make sure that the function selector is in the Heating position.
2. Make sure that the filter is clean.

DE-COMMISSIONING DISMANTLING & DISPOSAL
This product contains refrigerant under pressure, rotating parts, and electrical connections which may be a danger and cause injury !
All work must only be carried out by competent persons using suitable protective clothing and safety precautions.
1. Isolate all sources of electrical supply to the unit including any control system supplies switched by the unit. Ensure that all points of electrical
and gas isolation are secured in the OFF position. The supply cables and gas pipework may then be disconnected and removed. For points of
connection refer to unit installation instructions.
2. Remove all refrigerant from each system of the unit into a suitable container using a refrigerant reclaim or recovery unit. This refrigerant may
then be re-used, if appropriate, or returned to the manufacturer for disposal. Under NO circumstances should refrigerant be vented to
atmosphere. Where appropriate, drain the refrigerant oil from each system into a suitable container and dispose of according to local laws and
regulations governing disposal of oily wastes.
3. Packaged units can generally be removed in one piece after disconnection as above. Any fixing down bolts should be removed and then the
unit lifted from position using the points provided and equipment of adequate lifting capacity. Reference MUST be made to the unit installation
instructions for unit weight and correct methods of lifting. Note that any residual or spilt refrigerant oil should be mopped up and disposed of as
described above.
4. After removal from position the unit parts may be disposed of according to local laws and regulations.
