Repairs To Sealed Components - Gree GUD35P/A-T Manuel D'utilisateur

(5) 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.
5.4.1.9 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:
(1) That capacitors are discharged: this shall be done in a safe manner to avoid
possibility of sparking;
(2) That no live electrical components and wiring are exposed while charging,
recovering or purging the system;
(3) That there is continuity of earth bonding.

5.4.2 Repairs to Sealed Components

5.4.2.1 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.
5.4.2.2 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 notmade to original specification, damage to seals,
incorrect fitting of glands, etc.
