Product Instructions
Safety Instructions
The dehumidifier is used to remove excessive moisture from the air. The resulting reduction in relative
humidity protects buildings and their contents from the adverse effects of excess humidity.
The environmentally friendly R290 is used as the refrigerant. R290 has no damaging influence on the
ozone layer (ODP), a negligible greenhouse effect (GWP) and is available worldwide. Because of its
efficient energy properties, R290 is highly suitable as a coolant for this application. Special precautions
must be taken into consideration due to the coolant's high flammability.
This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made
by children without supervision.
The unit is designed only for use with R-290(propane) gas as the designated refrigerant.
THE REFRIGERANT LOOP IS SEALED. ONLY A QUALIFIED TECHNICIAN SHOULD ATTEMPT
TO SERVICE!
Do not discharge the refrigerant into the atmosphere.
R-290 (propane) is flammable and heavier than air.
It collects first in low areas but can be circulated by the fans.
If propane gas is present or even suspected, do not allow untrained personnel to attempt to find the
cause.
The propane gas used in the unit has no odor.
The lack of smell does not indicate a lack of escaped gas.
If a leak is detected, immediately evacuate all persons from the store, ventilate the room and contact
the local fire department to advise them that a propane leak has occurred.
Do not let any persons back into the store until the qualified service technician has arrived and that
technician advises that it is safe to return to the store.
No open flames, cigarettes or other possible sources of ignition should be used inside or in the vicinity
of the units.
Component parts are designed for propane and non-incentive and non-sparking. Component parts
shall only be replaced with identical repair parts.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
The appliance shall be disconnected from its power source during maintenance.
Ensure the unit is far away from fire, inflammable, or explosive objects.
Do not use means to accelerate the defrosting process or to clean, other than those recommended
by the manufacture.

Checking for presence of refrigerant
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.
Presence of fire extinguisher
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 CO²fire extinguisher
adjacent to the charging area.
No ignition sources
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.
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.

Checks to electrical devices
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.
Initial safety checks shall include:
-those 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.
Releasing refrigerant into atmosphere is strictly forbidden!
Checks to the refrigeration equipment
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.
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;
– 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
shall 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
