Output Capacity
Increasing or decreasing the nozzle size or
water pressure to the humidifier can vary the
output capacity of this humidifier. It is
recommended that the humidifier not be
used at water pressures below 40 PSI,
otherwise, the mist may be affected.
The following chart illustrates the capacity of
different nozzles at varying water pressures.
The output capacities shown are for water,
and are 1/2 the output capacity of the rated
oil nozzles. 1.00 oil = .50 water

WATER PRESSURE
This humidifier comes standard with a hollow
cone pattern .75 GPH nozzle, however,
additional nozzles may be purchased from
your local plumbing distributor or hardware
store. If the water pressure fluctuates or is
excessive, a small pressure regulator should
be installed in the water line supplying the
humidifier.
Output Capacity
Note:
Due to the operation cycle of the
furnace and humidifier, it may take
anywhere from 2 to 5 days to reach
the proper humidification level.
