Embraco Sliding unit Series, Руководство по установке

Страница: 8 / 48

We sometimes recommend isolating material be inserted between the unit feet and the base or between
the wall mounting brackets and the wall. This can be either an isolating pad or anti vibration mounts (not
supplied) conforming to the manufacturer’s recommendations for their selection and installation.
The selection of any anti-vibration products and their potential for absorbing vibration is not the
responsibility of Embraco.
3.5 Mounting. Ensure the unit is securely fixed to the type of floor or wall surface upon which it is
mounted using the appropriated fixings (not supplied).
Warning: do not fix the housed unit to a wall by the rear of the casing as it is not designed for this purpose.
Warning: do not open housed unit before fixing, the sliding front panel should be open only when the unit
is properly fixed to avoid the unit will fall down.
3.6 Access to connections. (See picture 3 )
3.7 Refrigeration connections. To ensure the quality of our products, the condensing unit has been
evacuated and charged with nitrogen.
WARNING: To maintain the quality of a EMBRACO condensing unit and to ensure it functions correctly,
the following precautions must be taken:
• check that the pipe work to be connected is clean and dry,
• protect the casing whilst brazing pipe work,
• purge the system with nitrogen whilst brazing and ensure the flame is held well away from electrical
equipment,
• insulate the suction line up to the valve compressor inlet to limit the suction superheat,
• only use the designated refrigerant for which the compressor is designed (see identification label),
• do not add any additives or colorings,
• ensure the pipe work is well supported and as short as possible between supports to prevent oil trapping
and to aid the absorption of vibration and pulsations,
• do not use longer suction pipes then 10 m,
• do not add oil inside the system.
In installations with vertical pipe risers, it may be necessary to create U traps and reduce the diameter of
the pipe work to ensure adequate speed for oil circulation.
• Ensure that any pressure relief connections are directed away from users to prevent them being exposed
to any danger.
• Cut and shape piping carefully to prevent dust and metallic particles getting into the system. Never use
a saw. Use the correctly sized bending tool for the pipe diameter to prevent the pipe being compressed.
EMBRACO recommends using brazed instead of flared connections to reduce the possibility of any leaks.
Flared connections using a connector and washer are acceptable.
• Tape the pipes together with self-adhesive vinyl tape and attach them to the wall with clips.
Warning: it is important to prevent damage to electrical cable insulation when using clips. A cable track
installed in compliance with NF C15-100 and separate from the refrigerant pipe work is preferred.
3.8 Electrical connections . The unit is fitted with a electrical box to which the factory installed
compressor, fan assembly, and main electrical box where pressure switch, crankcase heater and
main switch or contactor are connected via terminal block mounted on a DIN rail.
Ensure the electrical supply is disconnected before carrying out any wiring or repairs of the unit.
All cabling on site must conform with NF C15-100 in France or with the current legislation in the
country in question (NF EN 60204 /60335 in the EC).
