Air Conditioner Unit Operation; Standard Operating Conditions; Electrostatic Filter - McQuay IM-WMF-0501 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/3.6°F higher than the set
temperature, the air conditioner will operate under
cooling mode until it reaches within the 2°C/3.6°F range
of difference compared to the set temperature before it
converts to dry mode.
• If the room temperature is within the 2°C/3.6°F range
of difference compared to the set temperature, it will
directly operate under dry mode.
• The unit will operate at 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 the set temperature is achieved, the indoor fan
will operate until the coil cannot provide anymore
additional heat.
Horizontal Air Flow Control
• For more effective air circulation, you can manually
adjust the air discharge grille to the left or right.
• During cool mode operation and dry mode operation,
do not direct the air discharge louver downwards for too
long. If operating continues in this way, condensation
may occur on the louver, thus resulting in drippings.
Hot Keep (for heat pump only)
• During compressor cut off, the indoor fan can be
switched to
(i) ON (default) or
(ii) OFF or
(iii) Interval on and off
by setting the slide switch shown in the diagram.
• The switch is located at the front frame cover (next to
the ON/OFF switch).
NOTE : When the option is selected, the power supply of
the unit need to be reset in order to activate the
function.

ELECTROSTATIC AIR PURIFYING FILTER
Removes microscopic dust, smoke and small invisible
particles to keep the room air clean with pre-charged
electrostatic polypropylene filter.

ELECTROSTATIC FILTER

DUAL ACTION ELECTROSTATIC AIR PURIFYING
Overheating protection (for heat pump unit only)
• In case the internal and/or the external temperature is to
high, or that the filter is dirty and clogged up, the
refrigerant may be overheated. The compressor will cut
out when the condensing temperature reaches 62°C/
143.6°F.
Frost prevention
• When the air filter is dirty, the evaporating temperature
will decrease and eventually cause frosting.
• The LED light will blink to indicate that the filter is
dirty. If the evaporating temperature reaches -1°C/33.8°F,
the unit will trip and defrost.
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.
