3. Installation & Commissioning
3.1 Unit site location
• In order to achieve maximum cooling capacity, the
installation location for condensing unit should be
carefully selected.
• Install the condensing unit in such a way so that hot air
distributed by the condensing unit cannot be drawn in
again (as in the case of short circuit of hot discharge
air). Allow sufficient 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 intake 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, the condenser
coil must be cleaned at regular intervals.
3.2 Installation Clearance
• The installation location should allow sufficient space
for air flow and maintenance around the unit.
• To allow sufficient space for doing service or
installation.
3.3 Compressor handling
To ensure compressor reliability, the condensing unit and
the compressor must not be tilt greater than an angle of 45°.
Otherwise, the compressor can fall from its 3 compressor
housing spring, which results in noisy vibrations during
operation and possible to breakdown.
3.4 Field Piping
To ensure satisfactory operation and performance, the
following points should be noted for field piping
arrangements,
• Couples one indoor unit with one outdoor condensing
unit only.
• Release all the pre-charged nitrogen before pipework
connection.
• Connecting pipe size for suction and liquid line must
same as attaches to the condensing unit. Correct line
sizing will minimize the pressure drop and maintain
sufficient gas velocity for proper oil return.
• Pipework routes must be as simple and as short as
possible. Avoid low points on pipework where oil can
accumulate.
• Use only clean, dehydrated refrigeration grade copper
tube with large radius elbows. The piping shall be kept
with enough bending radius.
• Braze without over filling to ensure there is no excess
solder into the tube.
• To prevent oxidation, blow nitrogen through pipework
when brazing.
• Install insulation on all suction lines after pressure test.
• Adequately support all pipe work at a maximum of 2
meter intervals.
• For the condition where the outdoor condensing unit is
above the indoor unit, the height difference 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 difference between
units shall be less than 4 m. Pipe trap shall be installed
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
Important Note
Line sizing should only be determined by qualified
personnel. All local codes of practice must be observed
in the installation of refrigerant piping
