Before attempting to move the dehumidifier, empty the contents of the collection tank.
9
Use top carrying handle when moving unit.
9
Switch off and disconnect it from the mains before attempting any cleaning or other maintenance work.
9
Ensure that the dehumidifier is correctly turned off when not in use, and stored in a safe, dry area, out of reach of children.

NOTE: This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities or lack
of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person
responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

SAFETY PRECAUTIONS ON SERVICING
WARNING: Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate from
‰
an industry-accredited assessment authority, which authorizes their competence to handle refrigerants safely in accordance with an
industry, recognized assessment specification.
WARNING: Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring
‰
the assistance of other skilled personnel shall be carried out under the supervision of the person competent in the use of flammable
refrigerants.
WARNING: If you don't understand something or need help, please contact Sealey.

1.3.1.
Checks to the area
1.3.1.1. Prior to beginning work on systems containing flammable 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.
1.3.2.
Work procedure
1.3.2.1. Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapour being present while
the work is being performed.
1.3.3.
General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined
spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been
made safe by control of flammable material.
1.3.4.
Checking for presence of refrigerant
1.3.4.1.
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of
potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable
refrigerants, i.e. no sparking, adequately sealed or intrinsically safe.
1.3.5.
Presence of fire extinguisher
1.3.5.1. If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment
shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
1.3.6.
No ignition sources
1.3.6.1.
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has
contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or
explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of
installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding
space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable
hazards or ignition risks. "No Smoking" signs shall be displayed.
1.3.7.
Ventilated area
1.3.7.1.
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.
1.3.8.
Checks to the refrigeration equipment
1.3.8.1. Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the
manufacturer's maintenance and service guidelines shall be followed. If in doubt consult the manufacturer's technical department
for assistance.
1.3.8.2. The following checks shall be applied to installations using flammable refrigerants:
The charge size is in accordance with the room size within which the refrigerant containing parts are installed.
9
The ventilation machinery and outlets are operating adequately and are not obstructed.
9
If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant.
9
Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected.
9
Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may
9
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.
Checks to electrical devices
1.3.9.
1.3.9.1.
Repair and maintenance to electrical components shall 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 shall be used. This
shall be reported to the owner of the equipment so all parties are advised.
1.3.9.2.
Initial safety checks shall include:
those capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
9
that there no live electrical components and wiring are exposed while charging, recovering or purging the system.
9
that there is continuity of earth bonding.
