Maintenance - Sharp UD-P16E-W User Manual

Memory function
1. If the unit is turned off via the POWER button, when turned back on
again it will resume from the function it was turned off in. Note that if
the timer was set or if the unit was in the lock mode, these settings are
not stored.
2. If the mains power is disconnected while the unit is operating, it will
not start automatically when the mains is reconnected. When the mains
power is applied again, you will need to press the POWER button to
restart operation. The unit will start up in the initial mode.
Water tank full auto-stop function
When the water tank is full, the unit will stop operation, the air outlet
louver will close and a buzzer will sound. To reset, remove the water tank,
empty and replace. When the empty water tank is put back into the unit, it
will restart. Note that the compressor will take about 3 minutes to operate.
Auto defrost
If the unit is used in a low temperature environment, the internal
evaporator may be covered by frost. In order to make sure the machine
operates normally, the machine has auto-defrost function. Should
the internal sensor detect a temperature of ≤-1 °C the machine will
enter auto-defrost function. That means it will run continuously in the
dehumidification mode for 30 minutes, then the machine will start the
defrost cycle, the DEFROST light will illuminate, the compressor will stop
and that fan will operate at high speed.
When temperature of evaporator is ≥2 °C and the unit has been in the
defrost mode for 10 minutes, the auto-defrost mode will turn off and the
compressor turns on. At this point the unit will start to dehumidify and the
DEFROST light will turn off.
While in the defrost mode and the temperature of the evaporator is ≥0 °C
for two minutes, the defrost function is cancelled.
Compressor protection function
Should there be a problem with the unit causing the compressor to stop,
the compressor will turn off for 3 minutes. Normally the compressor will
restart after 3 minutes, if it does not unplug the unit for an hour and try
again. If it still does not start, call for service.
High/Low temperature protection
function
If the unit detects that the ambient temperature is outside of the normal
operating range of 5 °C to 38 °C, it will shut down. When the normal
operating range is reached, the compressor will start. Note that it will take
the compressor 3 minutes to start working once the normal temperature
range is met.
Low humidity protection function
If the unit detects low humidity of <30 % the display will indicate LO and
it will stop any dehumidifying action and the fan will operate a the lowest
speed.
If the humidity is over 80 %, the display will indicate HI and keep
dehumidifying.
High temperature fan speed switch
function
When the unit is dehumidifying in a high temperature environment and
the fan speed is set to low, it will switch automatically to the high speed.
This is to prevent excessive load on the compressor. When the ambient air
temperature reduces, the fan speed will return to the low setting.
Error codes
There are number of error codes which may appear in the display, these are
as below. When the error code is displayed, it will flash. If any of these error
codes are experienced, call for service.
C1 – Indicates that there is a fault with the evaporator temperature sensor.
In this condition, the unit will stop working.
C2 – Indicates that there is a fault with the ambient air temperature sensor.
In this condition, the unit will stop working.
C8 – The temperature of the evaporator checked every 8 minutes, if this is
within ≤3 °C of the ambient air temperature for 5 consecutive checks, the
unit will shut down and the error code C8 is displayed.
Continuous drainage function
Should it be necessary to provide continuous drainage, this can be
achieved by fitting a 15 mm inner diameter pipe to the drainage hole on
the rear of the unit. When installed, water will drain through the pipe and
not into the water tank.
Ensure that the drainage pipe runs in a downwards direction, and it not
bent or damaged in any way so that the water runs freely out of the unit.
When fitting the drainage pipe, make sure that it is pushed all the way into
the drainage hole so that it pushed over the drain outlet which is located
about 70mm inside the unit from the rear cover of the unit.
Refer to the 3 on page 1 for the location of the drainpipe connection port.

Maintenance

When cleaning your dehumidifier:
• Use a soft clean cloth.
• Do not use the alcohol, gasoline, and other benzene chemical solvents.
• To clean the filter, remove it, then use a vacuum cleaner to clear any dust
which may have built up. If necessary, use water to clean, then place it in
ventilated area until dry.
• Unplug the unit from the mains supply before cleaning.
Other advice:
• Before moving the unit, unplug the mains supply and pull out the water
in tank.
• If not using the unit for a long time, unplug the unit from the mains sup-
ply, empty the water tank, wait for 2 days to make sure the unit inside
completely dry before packing.
• Always store the unit in an upright position.
• Do not tilt the unit horizontally or turn upside down.
• If the unit requires repair, seek help of a professional person.
