E.
Prior to routing the refrigerant lines to the unit,
install the supplied flare nuts onto the refridgerant
lines. Using a 450 flaring tool, flare the refrigerant
lines. Remove the caps attached to the ends of
the refrigerant line connections at the cassette. A
nitrogen charge will leak out.
Using a torque wrench, torque the fittings to the
proper specifications. (See outdoor Unit Section
for flare torque settings.)
F.
Connect the grey flexible drain hose supplied with
the cassette unit to the condensate pump discharge
pipe of the cassette. Tighten the clamp securely.
Using the 3/4" PVC, connect the flexible hose to the
building's condensate drain system.
