    • The maximum number of pieces of equipment permitted to be stored together will be determined by local regulations.
  6. Information on servicing

    • Checks to the area: Before 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 before conducting work on the system.
    • Work procedure: Work shall be undertaken under a controlled procedure to minimize the risk of flammable gas or vapour being present while the work is being performed.
    • 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 controlling flammable material.
    • Checking for the presence of refrigerant: The area shall be checked with an appropriate refrigerant detector before 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. nonsparking, adequately sealed or intrinsically safe.
    • Presence of fire extinguisher: If any work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available on hand. Have a dry powder or CO2 fire extinguisher adjacent to the work area.
    • No ignition sources: No person carrying out work on a refrigeration system that 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, repair, and disposal, during which flammable refrigerant can be released into the surrounding space. Before work takes 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 opening 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 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 by 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 the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected; Refrigeration pipes or components are installed in a position where they are unlikely to be exposed to any substance that may corrode refrigerant-containing components unless the components are constructed of materials that are inherently resistant to being corroded or are suitably protected against being so corroded. Checks to electrical devices: Repair and maintenance of 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 That capacitors are discharged: this shall be done safely to avoid the possibility of sparking; That no live electrical components and wiring are exposed while charging, recovering, or purging the system; That there is continuity of earth bonding.
  7. 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 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 affected.
    • This shall include damage to cables, excessive number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
    • Ensure that the apparatus is mounted securely.
    • Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose of preventing the ingress of flammable atmospheres.
    • Replacement parts shall be to the manufacturer’s specifications.
      NOTE: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment. Intrinsically safe components do not have to be isolated before working on them.
  8. Repairs 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 living in the presence of a flammable atmosphere. The test apparatus shall be at the correct rating.
    • Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.
  9. Cabling

    • Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects.
    • The check shall a so take into account the effects of aging or continual vibration from sources such as compressors or fans.
  10. Detection of flammable refrigerants

    • Under no circumstances shall potential sources of ignition be used in these arching for or detection of refrigerant leaks.
    • A halide torch (or any other detector using a naked flame) shall not be used.
  11. Leak detection methods

    • The following leak detection methods are deemed acceptable for systems containing flammable refrigerants:

    • Electronic leak detectors shall be used to detect flammable 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 shall be calibrated to the refrigerant employed and the appropriate percentage of gas (25 % maximum) is confirmed.

    • Leak detection fluids 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 pipe-work.

    • If a leak is suspected, all naked flames shall be removed/ extinguished.

    • If a leakage of refrigerant is found that requires brazing, all of the refrigerant shall be recovered from the system, or isolated (using shutoff valves) in a part of the system remote from the leak.

    • Oxygen-free nitrogen (OFN) shall then be purged through the system both before and during the brazing process.

  12. Removal and evacuation

    • When breaking into the refrigerant circuit to make repairs – or for any other purpose

    • conventional procedures shall be used.
      However, for flammable refrigerants, best practices must be followed, since flammability is a consideration.

Cleaning the Exterior

  • Turn off the dehumidifier and unplug the power supply cord.
  • Dust the surface of the unit with a soft cloth or the dusting attachment of your vacuum cleaner.

Cleaning the Water Bucket

  • Every few weeks, rinse the inside of the water bucket with a mild detergent to avoid the growth of mould, mildew and bacteria.

Water level float

  • The dehumidifier’s water bucket (2) has a water level float (1).
  • Do not damage or remove the bucket’s water level float. If the float is not properly in place, the Empty Bucket light will turn on, preventing operation, and could result in leaking.Hisense-HD3524-2-Speed-Dehumidifier-FIG-19
