BEFORE YOU BEGIN

1.1 PRODUCT DESCRIPTION
The dehumidifier is used to remove excess 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) and a negligible greenhouse effect (GWP), and is available worldwide. Because of its energy-efficient properties, R290 is highly suitable as a refrigerant for this application. Special precautions must be taken into consideration due to the refrigerant’s high level of flammability.

1.2 SYMBOLS FROM THE UNIT AND USER MANUAL

2.2 SAFETY PRECAUTIONS FOR SERVICING
Please follow these warnings when servicing a dehumidifier with R290.
2.2.1 Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For any repair to the refrigerating system, the following precautions should be complied with prior to conducting work on the system.
2.2.2 Work procedures
Work should 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.
2.2.3 General work area
All maintenance staff and others working in the local area should be informed of the nature of the work being carried out. Working in confined spaces should be avoided, and the area around the workspace should be sectioned off. Ensure that the conditions within the area have been made safe by checking for flammable material.
2.2.4 Checking for presence of refrigerant
The area should be checked with an appropriate refrigerant detector prior to and during work, ensuring the technician is aware of potentially flammable properties. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e., nonspeaking, adequately sealed or intrinsically safe.
2.2.5 Presence of fire extinguisher
If any work involving heat is to be conducted on the refrigeration equipment or any associated parts, the appropriate fire extinguishing equipment should be available to hand.  Have a dry powder or Co2 fire extinguisher adjacent to the charging area.
2.2.6 No sources of ignition
No person carrying out work in relation to a refrigeration system which involves exposing any pipework that contains or has contained flammable refrigerant should use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible sources of ignition, including cigarette smoking, should be kept sufficiently far away from the site of installation, repair, removal and disposal, during which the flammable refrigerant has the potential to be released into the surrounding area. 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 should be displayed.
2.2.7 Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before opening up the system or conducting any work that involves heat. A certain amount of ventilation should be maintained during the time in which the work is being carried out. This ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
2.2.8 Checks to the refrigeration equipment
Where electrical components are changed, they should be fit for purpose and meet the correct specifications. The manufacturer’s maintenance and service guidelines should be followed at all times. If in doubt, consult the manufacturer’s technical department for
assistance.
The following checks should be applied to installations using flammable refrigerants:
– The charge size should be in accordance with the room size within which the refrigerant containing parts are installed;
– The ventilation machinery and outlets should be operating adequately, without any obstruction;
– If an indirect refrigerating circuit is being used, the secondary circuit should be checked for the presence of refrigerant;
– Markings on the equipment should be kept visible and legible. Markings and signs that are illegible should be corrected;
– the refrigeration pipe or components should be 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 such corrosion.
2.2.9 Checks to electrical components
Repair and maintenance to electrical components should include initial safety checks and component inspection procedures. If a fault exists that could compromise one’s safety, then no electrical supply should be connected to the circuit until the fault 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 informed.
Initial safety checks should include:
-those capacitors are discharged: this should be done in a safe manner to avoid the possibility of sparking;
-ensuring that there are no live electrical components or wiring exposed while charging, recovering or purging the system;
-checking that there is continuity of earth bonding.
