Do not expose drain line to freezing temperatures. Drain line may contain boiling water therefore use
copper or other suitable material. Drain line must comply with local building codes. It is recommended
to install under-oor leak detection equipment whenever possible.
Note: Condensation formation and frequent humidier ushing are normal functions
of this equipment. Proper drain connections must be made to ensure proper removal.
Unit will require water connections for condensate removal and possibly for humidier
makeup water, condenser water, water/glycol and/or hot water. Installation of units above
equipment that could sustain water damage should be avoided.
WARNING: The condensate drain MUST be connected to an external drain line (provided
by others) before unit start up.
2.9 Humidier Piping
2.9.1 Steam Generator Humidier
The standard humidier in the systems is a steam generator humidier type with disposable cylinder.
The humidier makeup water should be brought to the humidier through the eld connection opening
using 1/4” (6.4 mm) copper tubing. A compression tting is provided at the humidier.
A shuto󰀨 valve should be provided outside the air conditioner to allow disconnection for service. An in-
line water pressure regulator and strainer should be installed. Water pressure should be set between
20 and 80 PSI (128 and 552 kPa).
The humidier has a drain at the bottom which is factory piped to the main condensate drain line. The
dispersion tube also has a drain line. No additional eld piping is required.
Note: Do not supply steam generating humidier with softened water. Also, do not use
hot water source.
2.9.2 Dry Steam Humidier
2.0.1 The optional dry steam humidier requires a strainer on the inlet steam line. An outlet connection
with eld-provided steam trap is also required. Steam pressure is typical 10 to 15 PSI (69 to 103 kPa).
2.10 Leak Testing
WARNING: No installation is complete until the entire system has been thoroughly
checked for leaks. This includes checking the refrigerant tubing, are ttings, pressure
controls, Schrader ttings and compressor roto-lock service valves. Check both the
eld and factory connections,
In addition to refrigeration system, check all condenser water lines, humidier water makeup lines,
condensate lines, condensate pumps, chilled water lines, centrifugal pumps and uid cooler (where
applicable).
