building structure in accordance with local codes and good

building practices.

Step 6 — Provide for Condensate Disposal

NOTE: Ensure that condensate--water disposal methods comply
with local codes, restrictions, and practices.
The 50JZ--A units dispose of condensate through a 3/4 in. NPT
female fitting that exits on the compressor end of the unit.

Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground

level installations. Install a field--supplied condensate trap at end of

condensate connection to ensure proper drainage. Make sure that
the outlet of the trap is at least 1 in. (25 mm) lower than the

drain--pan condensate connection to prevent the pan from
overflowing. Prime the trap with water. When using a gravel apron,

make sure it slopes away from the unit.
If the installation requires draining the condensate water away from
the unit, install a field--supplied 2 --in. (51mm) trap at the

condensate connection to ensure proper drainage. Condensate trap
is available as an accessory or is field--supplied. Make sure that the

outlet of the trap is at least 1 in. (25 mm) lower than the unit
drain--pan condensate connection to prevent the pan from

overflowing. Connect a drain tube using a minimum of

field--supplied 3/4--in. PVC or field--supplied 3/4--in. copper pipe
at outlet end of the 2--in. (51 mm) trap. (See Fig. 8.) Do not

undersize the tube. Pitch the drain tube downward at a slope of at
least 1 in. (25 mm) every 10 ft (3 m) of horizontal run. Be sure to

check the drain trough for leaks. Prime the trap at the beginning of

the cooling season start--up.
