Piping Work - Samsung AE050RXYDEG Installation Manual

Piping work

Water connections must be made in accordance with the outlook diagram delivered with the unit, respecting the water
in- and outlet . If air, moisture or dust gets in the water circuit, problems may occur . Therefore, always take into account the
following when connecting the water circuit:
f Use clean pipes only . f
f Hold the pipe end downwards when removing burrs .
f
f Cover the pipe end when inserting it through a wall so that no dust and dirt enter . f
f Use a good thread sealant for the sealing of the connections .
f
The sealing must be able to withstand the pressures and temperatures of the system .
f When using non-brass metallic piping, make sure to insulate both materials from each other f
to prevent galvanic corrosion .
f Because brass is a soft material, use appropriate tooling for connecting the water circuit .
f
Inappropriate tooling will cause damage to the pipes .
• Be careful not to deform the unit piping by using excessive force when connecting the piping . Deformation of
the piping can cause the unit to malfunction .
CAUTION
• Always use two wrenches (spanners) for tightening or loosening the water connections, and tighten
connections with a torque wrench as specified in below table . If not, connections and parts can be damaged
and leaks .
• The unit is only to be used in a closed water system . If applications are in open water circuit, it will generate Heat
exchangers fouling, Corrosion, Leak .

Flushing and air-purging
When filling water, the following start-up procedure should be followed .
1 . All system components and pipes must be tested for the presence of leaks .
2 . Preparation of a make-up water assembly or flushing unit is recommended for installation
and service .
3 . Before connecting pipes to the Outdoor Unit, flush water pipes clean to remove
contaminants during hours using a flushing unit or tap water pressure if it is adequate (at
2 to 3 bar)
4 . Fill water into the Outdoor Unit by opening shut-off & drain valve .
5 . Purge the air . (Fill with a flushing unit with sufficient capacity: avoid aerating the water)
6 . Circulate for long enough to ensure that all air has been bled from the complete water
piping system .
• After installations, commissioning should be performed by qualified
representatives . Unless flushing and air-purging works are performed
CAUTION
adequately, it might result in malfunctions .
