3. Installa ti on & Comm iss ioning
3.1 Unit site location
• In order to achieve maximum cooling capacity, the
installation location for condensing unit should be
carefully selected.
• Install the condensi ng unit in such a way so that hot air
distri buted by the condensing unit cannot be drawn in
again (as in the case of short circuit of hot discharge
air). Allow suffic i ent space for maintenance around the
unit.
• Ensure that there is no obstruction of air flow into or out
of the unit. Remove obstacles which block air intak e or
discharge.
• The location must be well ventilated, so the unit can
draw in and distribute plenty of air thus lowering the
condensing temperature.
• To optimize the unit running conditions, t he condens er
coil must be cleaned at regular intervals.
3.2 Installation Clearan ce
• The installation l ocat i on should allow suffici ent s pace
for air flow and maintenance around the unit.
• To allow sufficient space for doing servic e or
installation.
3.3 Compressor handling
To ensure compressor reliabili ty, the condensing unit and
the compressor must not be tilt greater than an angle of 45°.
Otherwise, the compressor c an fall from its 3 compressor
housing spring, which results in noisy vibrati ons during
operation and possibl e to breakdown.
3.4 Field Piping
To ensure satisfactory operati on and performance, the
following points s houl d be noted for field piping
arrangements,
• Couples one indoor unit with one outdoor condens i ng
unit only.
• Release all the pre-charged nitrogen before pi pework
connection.
• Connecting pipe si ze for suction and liquid li ne must
same as attaches to the condensing unit. Correct line
sizing will minim i ze the pressure drop and maintai n
sufficient gas velocit y for proper oil return.
• Pipework routes must be as simple and as short as
possibl e. Avoid low points on pipework where oil can
accumulate.
• Use only clean, dehydrated refrigeration grade c opper
tube with large radius elbows. The piping shall be kept
with enough bending radius.
• Braze without over filling t o ensure there is no excess
solder int o the tube.
• To prevent oxidation, blow nitrogen t hrough pi pework
when brazing.
• Install i nsulation on all sucti on lines after press ure test.
• Adequately support al l pipe work at a maximum of 2
meter intervals.
• For the condition where the outdoor condensing unit is
above the indoor unit, the height differenc e between
units shall be less than 25 m and install oil trap on
suction pipe every 4 m height. The suction pipe must
always be fitted with U-trap at the bottom.
• For the condition where the outdoor condensing unit is
below the indoor unit, the height diff erence between
units shall be less than 4 m. Pipe trap shall be install ed
upward on outlet of indoor unit (suction pipe).
• The recommended piping length is 25 m or less.
• Additional oil might be required in case field piping is
long or with many oil traps. Check the oil level of the
