7 RETURN DUCTWORK
Do not locate the return ductwork in an area that can introduce
toxic or objectionable fumes/ordors into the ductwork.
8 REFRIGERANT PIPING WORK
IMPORTANT NOTE: Do not handle coil assembly with manifold
liquid tubes or flowrator tubes. Doing so may result in damage to
the tubing joints. Always use clean gloves for handling coil assem-
blies.
8.1 Tubing Size/Length
Give special consideration to minimizing the length of refrigerant
tubing when installing cased coil. Refer to outdoor unit INSTALLA-
TION & SERVICE REFERENCE for line set configuration guidelines.
If possible, allow adequate length of tubing, so that the coil may be
removed (for inspection or cleaning services) from the cabinet
without disconnecting the tubing.
