22 ā gForce Ultra User Manual 10-2014
A trap should be built into the drain line to prevent air from backing up into the unit.
Drain lines should be pitched downward not less than 1/4ā (6.35 mm) for each ten (10)
feet (3.1 m) of horizontal run. Do not reduce the size of the drain line.
Some applications have no convenient means of allowing a gravity drain. When
required, an optional condensate pump can be used. Condensate pumps are either
factory mounted or shipped loose. Factory mounted condensate pumps do not require
a separate power source.
Condensate pumps shipped loose (or field provided) typically require a dedicated 110
volt power source. Field pipe connections must be made to the pump discharge
connection. A check valve must be installed to prevent short cycling. See condensate
pump electrical requirements in Section 3.9.
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-floor leak detection equipment
whenever possible.
Note:
Condensation formation and frequent humidifier flushing 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 humidifier makeup water, condenser water, chilled
water 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.
Note:
Clogged or leaking drain lines can cause damage to the equipment
and building.
Drain lines must be inspected regularly and maintenance must be
performed to ensure that drain lines are clear and condensation runs freely
through the drain system. The lines must be clear and free of obstructions
and in good condition with no visible sign of damage or leaks.
