Congratulations on purchasing
a misting system for your plants! They will show their appreciation!
Your misting system will also help cool your greenhouse during hot weather. Heat is
absorbed in the process of evaporation of the mist. However, shading from excessive sun,
and adequate ventilation are also necessary. Provide 24-hour air circulation to minimize
plant disease, and during colder months, maintain lower humidity.
INSTALLATION:
Install the Control Assembly where the Filter is accessible for cleaning, and where the
Pressure Gauge is visible.
The Control Assembly comes ready to connect to ½" I.D. PVC pipe.* To connect to a garden
hose, remove the 1/2" PVC inlet adapter and replace with brass garden hose adapter,
included. To connect to ½" metal pipe, remove the ½" PVC adapter.
Complete the pipe system for the mist nozzles using ½" I.D. PVC pipe and pipe cement* (not
included) and PVC Tees. Install the nozzles approximately 30 inches apart. When installing
PVC pipe in the Clic Pipe Hangers, press very firmly to snap the pipe into the hanger.
Be sure to flush the water lines before installing the nozzles.
*PLEASE NOTE:
Clic PVC Pipe Hangers fit rigid Schedule 40 PVC pipe with
1/2" ID (inside diameter) and 3/4" OD (outside diameter).
Clic Hangers do not fit Schedule 80 PVC pipe.

Tips on Pipe & Nozzle Location:
Install the PVC pipe under the benches along the aisle, and mount the nozzles to
direct the mist under the bench and away from the aisle. Nozzles may be
installed overhead for propagation areas, or where there is no danger of water
damage to flower blooms or sensitive foliage, as well as equipment. Space
overhead nozzles 36" to 48" apart.
MIST TIMER:
When installing the Short-Cycle Misting Timer be careful to protect the Timer
from any direct water, mist or spray.
To operate, plug the Solenoid (water valve) extension cord into the plug on
the Timer. Next, plug the Timer into a standard 110-120 volt outlet. The Timer
will now control the system automatically to maintain the misting level you
select.
SYSTEM OPERATION:
Use a humidity meter to check the humidity level in various parts of the
greenhouse. If you have an exhaust fan, you will probably find a higher level
of humidity near the fan when it is on, and a lower level near the intake
vents. Keep this difference in mind when selecting a location for your
particular plants.
You will notice a significant rise in relative humidity when the sun goes down
and the greenhouse temperature drops. If this presents a problem for your
plants, install a 24-hour timer to turn the misting system off well in advance
of sundown. This will allow the greenhouse to dry somewhat and will avoid
excessive condensation.
IMPORTANT: Drain system to prevent damage if the system will be exposed to
freezing temperatures.
SYSTEM MAINTENANCE:
Periodically clean the main filter: turn off the water, remove bottom cap,
and flush the filter screen. Also clean the mist nozzle filters.
For cooling, watering and humidity control, order the 2.7 gph nozzles #M6032-2.
