Air Conditioner Unit Operation; Standard Operating Conditions - McQuay IM-WMX-0603 Manual De Instalación

Dry mode
• When the air humidity is high, the unit can operate in dry
mode. Press <MODE> button and choose <DRY>.
• If the room temperature is 2°C higher than the set
temperature, the air conditioner will operate under cooling
mode until it reaches within the 2°C range of
difference compared to the set temperature before it
converts to dry mode.
• If the room temperature is within the 2°C range of
difference compared to the set temperature, it will
directly operate under dry mode.
• The indoor fan will operate at super low speed under dry
mode.
Heat mode (for heat pump unit only)
• When the unit is switched on from cold start or
defrosting cycle, the indoor fan will start to operate only
after the coil reaches the desired temperature.
• When compressor stops; the indoor fan will operate until
the coil temperature drops to a low level.
Horizontal Air Flow Control
• For more effective air circulation, you can manually ad-
just the air discharge grille to the left or right.
• During cool mode operation and dry mode operation, do
not direct the air discharge louvre downwards for too long.
If operating continues in this way, condensation may oc-
cur on the louvre, thus resulting in drippings.
Overheating protection (for heat pump unit only)
• In case the internal and/or the external temperature is too
high, or the filter is dirty and clogged up, the refrigerant
may be overheated. The compressor will reduce its running
speed in order to lower the temperature of heat exchanger.
If the temperature is still very high, the compressor will
stop.

Frost prevention
• When the air filter is dirty, the evaporating temperature
will decrease and eventually cause frosting.
• When this happens, the compressor will reduce its running
speed to prevent frezzing. If the coil temperature is still
very low, the compressor will stop.
Fan speed and rated cooling capacity
• The rated cooling capacity is provided at the maximum
fan speed.
• The cooling capacity is lower when the unit is operating at
MEDIUM and LOW fan speed.
Turbo function
• If higher cooling or heating is required during operation,
press "Turbo" button on the remote control to increase the
cooling or heating capacity to maximum.
• This function will operate for 15 minutes before it resume
to the actual setting.
• The fan noise may be higher if the unit operates in "Turbo"
mode.
