CONNECTING REFRIGERANT PIPING LINES
17-3 INSTRUCTIONS OF CONNECTIING REFRIGERANT PIPING LINES
 Avoid excessive height difference between
indoor and outdoor units.
 Keep the height difference to a strict minimum
to avoid alteration on system cooling
performance.
 Avoid excessive length of refrigerant piping
lines between outdoor and indoor units.
 Keep the height difference to a strict minimum
to avoid alteration on system cooling
performance.
 Avoid excessive number of turns and bends in
refrigerant piping lines during connections
with both the indoor and outdoor units.
 Keep the number of turns and bends to a strict
minimum to avoid alteration on system
cooling performance.
 Piping must be performed by qualified
installer according to good refrigeration
systems practices.
 Piping materials and insulation materials must
be of refrigerant quality.
- Select the pipe diameters to the size of system
to be installed.
- All bends must be considered when connecting
indoor unit with outdoor unit by required length
of refrigerant piping lines.
- Do not remove the protective caps from the
couplings until the refrigerant piping lines are
ready for connection with both indoor and
outdoor units. This is to keep piping clean.
- The installer must carefully unroll the tubing and
run it between the indoor and outdoor units.
● Do not bend the pipe more than three times
at one place.
● When extending the rolled pipe, straighten
the pipe by unwinding it.
When forming the pipe. Be careful not to crush it.
- Avoid pipes flattering or kinking.
- The minimum radius of bending must not be
less than 100 mm to avoid damage of piping.
