Information on servicing
1. Checking the area
• Prior to beginning work on systems
containing ammable refrigerants,
safety checks are necessary to ensure
that the risk of ignition is minimized. For
repair to the refrigerating system, the
following precautions shall be complied
with prior to conducting work on the
system.
2. Work procedure
• Work shall be undertaken under a
controlled procedure so as to minimize
the risk of a ammable gas or vapor
being present while the work is being
performed.
3. General work area
• All maintenance sta and others
working in the local area shall be
instructed on the nature of work being
carried out. Work in conned spaces
shall be avoided. The area around
the workspace shall be sectioned o.
Ensure that the conditions within the
area have been made safe by control of
ammable material.
4. Checking for presence of refrigerant
• The area should be checked with
an appropriate refrigerant detector
prior to and during work, to ensure
the technician is aware of potentially
ammable atmospheres. Ensure that
the leak detection equipment being
used is suitable for use with ammable
refrigerants, i.e. non-sparking,
adequately sealed or intrinsically safe.
5. Presence of a re extinguisher

IMPORTANT SAFETY INSTRUCTION
WARNING
(For using R290/R32 refrigerant only)
7. Ventilated area
• Ensure that the area is in the open or
that it is adequately ventilated before
breaking into the system or conducting
any hot work. A degree of ventilation
shall continue during the period that
the work is carried out. The ventilation
should safely disperse any released
refrigerant and preferably expel it
externally into the atmosphere.
8. Checks to the refrigeration equipment
• Where electrical components are
being changed, they shall be t for the
purpose and to the correct specication.
At all times the manufacturer’s
maintenance and service guidelines
shall be followed. If in doubt consult the
manufacturer’s technical department for
assistance.
• The following checks shall be applied to
installations using ammable refrigerants:
• The charge size is in accordance
with the room size within which the
refrigerant containing parts are
installed.
• The ventilation machinery and
outlets are operating adequately
and are not obstructed.
• If an indirect refrigerating circuit is
being used, the secondary circuit
shall be checked for the presence
of refrigerant.
• Marking to the equipment continues
to be visible and legible. Markings
and signs that are illegible should
be corrected.
• Refrigeration pipe or components
are installed in a position where
they are unlikely to be exposed to
any substance which may corrode
refrigerant containing components,
unless the components are
constructed of materials which
are inherently resistant to being
corroded or are suitably protected
against being so corroded.
9. Checks to electrical devices
• Repair and maintenance to electrical
components should include initial safety
checks and component inspection
procedures. If a fault exists that could
compromise safety, then no electrical
supply shall be connected to the circuit
until it is satisfactorily dealt with. If the
fault cannot be corrected immediately
but it is necessary to continue
operation, an adequate temporary
solution should be used. This should be
reported to the owner of the equipment,
so all parties are advised.
• Initial safety checks should include:
• That capacitors are discharged: this
shall be done in a safe manner to
avoid possibility of sparking.
• That there no live electrical
components and wiring are exposed
while charging, recovering or
purging the system.
• That there is continuity of earth
bonding.
10. Repairs to sealed components
• During repairs to sealed components, all
electrical supplies shall be disconnected
from the equipment being worked upon
prior to any removal of sealed covers,
etc. If it is absolutely necessary to have
an electrical supply to equipment during
servicing, then a permanently operating
form of leak detection shall be located
at the most critical point to warn of a
potentially hazardous situation.
• Particular attention shall be paid to the
following to ensure that by working on
electrical components, the casing is not
altered in such a way that the level of
protection is aected. This shall include
damage to cables, excessive number
of connections, terminals not made to
original specication, damage to seals,
incorrect tting of glands, etc.
(Continued)

9
IMPORTANT SAFETY INSTRUCTION
• Ensure that seals or sealing materials
have not degraded such that they no
longer serve the purpose of preventing
the ingress of ammable atmospheres.
Replacement parts should be in
accordance with the manufacturer’s
specications.
NOTE: The use of silicon sealant may
inhibit the eectiveness of some
types of leak detection equipment.
Intrinsically safe components do not
have to be isolated prior to working
on them.
11. Repair to intrinsically safe components
• Do not apply any permanent inductive
or capacitance loads to the circuit
without ensuring that this will not exceed
the permissible voltage and current
permitted for the equipment in use.
Intrinsically safe components are the
only types that can be worked on while
live in the presence of a ammable
atmosphere. The test apparatus shall
be at the correct rating.
• Replace components only with parts
specied by the manufacturer. Other
parts may result in the ignition of
refrigerant in the atmosphere from a leak.
12. Cabling
• Check that cabling will not be subject
to wear, corrosion, excessive pressure,
vibration, sharp edges or any other
adverse environmental eects. The
check shall also take into account the
eects of aging or continual vibration
from sources such as compressors or
fans.
13. Detection of ammable refrigerants
• Under no circumstances, should
potential sources of ignition be used
in the searching for or detection of
refrigerant leaks. A halide torch (or any
other detector using a naked ame)
should not be used.
14. Leak detection methods
• The following leak detection methods
are deemed acceptable for systems
containing ammable refrigerants.
Electronic leak detectors shall be used
to detect ammable refrigerants, but
the sensitivity may not be adequate,
or may need re-calibration. (Detection
equipment should 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 should
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 conrmed.
• Leak detection uids are suitable for
use with most refrigerants but the use of
detergents containing chlorine shall be
avoided as the chlorine may react with
the refrigerant and corrode the copper
pipework.
• If a leak is suspected, all naked ames
should be removed/ extinguished. If a
leakage of refrigerant is found which
requires brazing, all of the refrigerant
should be recovered from the system,
or isolated (by means of shut o valves)
in a part of the system remote from the
leak. Oxygen free nitrogen (OFN) should
then be purged through the system both
before and during the brazing process.
WARNING
(For using R290/R32 refrigerant only)
(Continued)

IMPORTANT SAFETY INSTRUCTION
15. 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
ammability is a consideration. Opening
of the refrigeration systems should not
be done by brazing.
• 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 should be
recovered into the correct recovery
cylinders. The system should be 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 should be achieved by breaking
the vacuum in the system with OFN
and continuing to ll until the working
pressure is achieved, then venting to
atmosphere, and nally pulling down to a
vacuum. This process shall be repeated
until no refrigerant is within the system.
• When the nal OFN charge is used,
the system shall be vented down to
atmospheric pressure to enable work to
take place. This operation is absolutely
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.
16. Charging procedures
• In addition to conventional charging
procedures, the following requirements
should be followed. Ensure that
contamination of dierent refrigerants
does not occur when using charging
equipment. Hoses or lines should be
as short as possible to minimize the
amount of refrigerant contained in them.
• Cylinders should be kept upright.
• Ensure that the refrigeration system is
earthed prior to charging the system
with refrigerant.
• Label the system when charging is
complete (if not already).
• Extreme care should be taken not to
overll the refrigeration system.
• Prior to recharging the system, it
should be pressure tested with OFN.
The system should be leak tested on
completion of charging but prior to
commissioning. A follow up leak test
should be carried out prior to leaving the
site.
WARNING
(For using R290/R32 refrigerant only)
(Continued)

11
17. Decommissioning
• Before carrying out this procedure,
it is essential that the technician is
completely familiar with the equipment
and all its detail. It is recommended
good practice that all refrigerants
are recovered safely. Prior to the task
being carried out, an oil and refrigerant
sample should be taken in case analysis
is required prior to re-use of reclaimed
refrigerant. It is essential that electrical
power is available before the task is
commenced.
• Become familiar with the equipment
and its operation.
• Isolate the system electrically.
• Before attempting the procedure
ensure that:
• When breaking into the
refrigerant circuit to make
repairs or for any other
purpose, conventional
procedures should be used.
• Mechanical handling equipment
is available, if required, for
handling refrigerant cylinders.
• Personal protective equipment
is available and being used
correctly.
• The recovery process is
supervised at all times by a
competent person.
• Recovery equipment and
cylinders conform to the
appropriate standards.
• Pump down refrigerant system, if
possible.
• If a vacuum is not possible, make a
manifold so that refrigerant can be
removed from various parts of the
system.
• Make sure that cylinder is situated
on the scales before recovery takes
place.
• Start the recovery machine
and operate in accordance with
manufacturer’s instructions.
Do not overll cylinders. (No more
than 80 % volume liquid charge).
• Do not exceed the maximum
working pressure of the cylinder,
even temporarily.
• When the cylinders have been
lled correctly and the process
is completed, make sure that the
cylinders and the equipment are
removed from the site promptly and
all isolation valves on the equipment
are closed o.
• Recovered refrigerant should not be
charged into another refrigeration
system unless it has been cleaned
and checked.
WARNING
(For using R290/R32 refrigerant only)
(Continued)
IMPORTANT SAFETY INSTRUCTION

12
18. Labelling
• Equipment should be labelled stating
that it has been de-commissioned and
emptied of refrigerant. The label should
be dated and signed. Ensure that there
are labels on the equipment stating
the equipment contains ammable
refrigerant.
19. Recovery
• When removing refrigerant from
a system, either for servicing or
decommissioning, it is recommended
good practice that all refrigerants are
removed safely.
• When transferring refrigerant into
cylinders, ensure that only appropriate
refrigerant recovery cylinders are
employed. Ensure that the correct
number of cylinders for holding the total
system charge is available. All cylinders
to be used are designated for the
recovered refrigerant and labelled for
that refrigerant (i.e. special cylinders for
the recovery of refrigerant). Cylinders
shall be complete with pressure relief
valve and associated shut-o valves in
good working order. Empty recovery
cylinders are evacuated and, if possible,
cooled before recovery occurs.
• The recovery equipment shall be
in good working order with a set of
instructions concerning the equipment
that is at hand and shall be suitable for
the recovery of ammable refrigerants.
In addition, a set of calibrated weighing
scales shall be available and in good
working order.
• Hoses shall be complete with leak-
free disconnect couplings and in
good condition. Before using the
recovery machine, check that it is in
satisfactory working order, has been
properly maintained and that any
associated electrical components
are sealed to prevent ignition in the
event of a refrigerant release. Consult
manufacturer if in doubt.
• The recovered refrigerant shall be
returned to the refrigerant supplier in
the correct recovery cylinder, and the
relevant Waste Transfer Note arranged.
Do not mix refrigerants in recovery
units and especially not in cylinders. If
compressors or compressor oils are to
be removed, ensure that they have been
evacuated to an acceptable level to
make certain that ammable refrigerant
does not remain within the lubricant. The
evacuation process shall be carried out
prior to returning the compressor to the
suppliers. Only electric heating to the
compressor body should be employed
to accelerate this process. When oil
is drained from a system, it should be
carried out safely.

REMOVING THE COLLECTED WATER
There are three ways to remove collected water:
1
USING THE BUCKET
• If the unit is OFF, and the bucket is full, the
FULL indicator light will illuminate.
• If the unit is ON, and the bucket is full, the
compressor and fan will turn o.
Then, the full indicator light will illuminate and
the LED display will show code P2.
EMPTY AND REINSERT THE BUCKET...
• Grip the left and right bucket handles securely,
and carefully pull out straight so water does
not spill. Do not place the bucket on the oor
because the bottom of the bucket is uneven
and the water may spill. Code EB will show on
the display panel when the bucket is removed.
Empty the water from bucket into a drain.
• The bucket must be replaced carefully and
securely for the dehumidier to operate. The
code EB will disappear from the display panel
and unit will re-start with the last used settings
after the bucket is returned to its correct
position.
1. Partially remove the bucket
2. Hold both sides of the bucket with even strength,
and completely remove from the unit and pour
out the water.
NOTE:
For 3PFDP50 model only, before
reinserting the bucket, the pump arm on
the right-side of the bucket area will need
to be lifted back up into position.
NOTE:
• When you remove the bucket, do not touch
any parts inside the unit. Doing so may
damage the product.
• Be sure to push the bucket gently all the
way into the unit. Banging the bucket
against anything or failing to push it in
securely may cause the unit not to operate.
• If the pump hose drops when you remove
the bucket, you must reinstall the pump
hose properly to the unit before replacing
the bucket into the unit.
• If there is some water in the unit after
you remove the unit after you remove the
bucket, you must dry it.
• If the bucket is removed while the unit is
running, the compressor and the fan will
turn o, the unit will beep 8 times and the
digital display will show P2.
• If the bucket is removed while the unit is
turn o, the unit will beep 8 times and the
digital display will show P2.
3PFDP50 MODELS ONLY:
Pump arm needs to be pushed back up into place
before reinserting the bucket:
Pump arm drops
Reinstall pump
arm properly

CONTINUOUS DRAINING
Continuous drainage uses gravity to pull the water
out of the unit through a hose. A white screw cap
covers the continuous drain outlet; Unscrew it to
attach the continuous drain hose. The drainage
outlet hose must be sealed with the provided cap
when not in use. Failure to tightly seal the cap if
drain is not in use will cause leaking water.
• A maximum 6ft length garden hose
(ld≥Φ5/16′′, not included) with a female
threaded end (ID:M=1′′, not included) can be
used for the continuous drainage option. The
unit is not designed to secure a vinyl hose and
can cause leaking water.
• The continuous drain hose must be placed in
a downward angle at all time. A maximum 6ft
length will prevent backups on days of extra
humidity. Any upward angles or sharp bends
will cause the water to either become stuck
inside the hose or backup into the unit.
• A small water pan inside of the unit is
already installed on the optional angle to
route water out as soon as the unit creates
it. Dehumidiers are designed to be used
on leveled oors. If the unit is placed on an
unleveled or even slightly forward angle the
water will run into the bucket as a backup.
• Basement oors will always have a slight
downward slope towards the oor drain.
Place the unit so the back panel is facing
the oor drain.
3
PUMP DRAINAGE (3PFDP50 ONLY)
Water pumps provide much more exibility for
drainage options. It can pump water vertically
(straight up) a maximum height of 16FT and as far
as 16FT length; This is ideal for routing water out
a window, to a distant oor drain, or into a sink so
the unit can stay on a secure oor. The pump turns
on when the water bucket is completely full and
will expel 32oz of water, about half of the bucket,
before stopping.
• A maximum 16FT length hose (ΦOD=1/4”,
included) can be used for the pump option.
• To install the hose, make sure it is pushed into
the pump drain outlet to a depth of at least 1/2
inch (approx. 15 mm). Once the hose is installed
to the proper depth, the holder will lock it in
place. The other end of the hose is placed in a
oor drain or the location water will drain.
• Then, press the PUMP button on the display
panel to turn on the water pump feature.
The pump will activate only when the pump
light indicator on the display is on and the
water bucket is full. It will expel 32oz of water,
about half the bucket, and then turn o.
Recommend to completely empty the water
bucket and clean it every week to prevent
stagnant water and mold growth.
• The hose should always be removed when the
pump feature is not being used. To remove the
hose, rmly press on the plastic ring around
the pump hose outlet and gently pull on the
hose. Do NOT force the hose to detach from
the holder by only pulling on it; This will cause
permanent damage to the unit. Be aware,
residual water may expell from the unit when
removing the hose.
