Pipe lengths calculated for Indoor unit with Airedale Outdoor Unit match.
IMPORTANT
Tandem Compressor and suction throttle valve applications: In part load, gas velocity should be taken into account
when selecting and commissioning pipework to ensure full oil return.
IMPORTANT
REMEMBER excessive pressure loss in interconnecting pipework will impair system performance; this should be
factored in during the design of the system and where necessary oil separators employed.
