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 fl ash. 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 fi tting 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 fi tting 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 dehumidifi er:
• Use a soft clean cloth.
• Do not use the alcohol, gasoline, and other benzene chemical solvents.
• To clean the fi lter, 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
supply, 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.
Engineer information
1. Cabling
Ensure that any cabling is not subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse environmental
eff ects. Also be aware of any eff ects cause by aging or continual leaks.
A halide torch (or any other detector using a naked fl ame) must not be
used.
2. Detection of fl ammable refrigerants
DO NOT use any possible sources of ignition to search for refrigerant
leaks. A halide torch (or any other detector using a naked fl ame) must
not be used.
3. Leak detection methods
The following leak detection methods are deemed acceptable for systems
containing fl ammable refrigerants.
Electronic leak detectors can be used to detect fl ammable refrigerants,
but the sensitivity may not be adequate, or may need re-calibration
(detection equipment shall be calibrated in a refrigerant-free area).
Ensure that the detector is not a potential source of ignition and is
suitable for the refrigerant used. Leak detection equipment shall be set
at a percentage of the LFL of the refrigerant and shall be calibrated to
the refrigerant employed and the appropriate percentage of gas (25%
maximum) is confi rmed.
Leak detection fl uids are suitable for use with most refrigerants but the
use of detergents containing chlorine must be avoided as the chlorine
may react with the refrigerant and corrode the copper pipework.
If a leak is suspected, all naked fl ames must be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the
refrigerant gas must be recovered from the system, or isolated (by means
of shut off valves) in a part of the system both before and during the
brazing process.
4. Removal and evacuation
When breaking into the refrigerant circuit to make repairs- or for any
other purpose – conventional procedures shall be used. However,
it is important that best practice is followed since fl ammability is a
consideration. The following procedure shall be adhered to:
Remove refrigerant.
Purge the circuit with inert gas.
Evacuate.
Purge again with inert gas.
Open the circuit by cutting or brazing.
The refrigerant charge shall be recovered into the correct recovery
cylinders. The system shall be "fl ushed' with OFN to render the unit safe.
This process may need to be repeated several times. Compressed air or
oxygen shall not be used for this task.
Flushing shall be achieved by breaking the vacuum in the system with
OFN and continuing to fi ll until the working pressure is achieved, then
venting to atmosphere, and fi nally pulling down to a vacuum. This
processing shall be repeated until no refrigerant is within the system.
When the fi nal OFN charge is used, the system shall be vented down to
atmospheric pressure to enable work to take place. This operation is vital
if brazing operations on the pipework are to take place. Ensure that the
outlet for the vacuum pump is not close to any ignition sources and there
is ventilation available.
5. Charging procedures
In addition to conventional charging procedures, the following
requirements shall be followed.
Ensure that contamination of diff erent refrigerants does not occur when
using charging equipment.
Hoses or lines shall be as short as possible to minimize the amount of
refrigerant contained in them.
Cylinders must be kept upright.
Ensure that the refrigeration system is earthed prior to charging the
system with refrigerant.
