Useful Tips for Mist System Layout
For the most effective cooling:
1. Mist line is placed around the perimeter of the area to be cooled. This forms a “mist
curtain,” a cooling barrier between the protected area and the outside heat.
2. Place mist nozzles 24 in. apart for mist lines mounted 8 ft. to 10 ft. above the ground.

increments, 10 ft. of feed line, a hose adapter and a threaded end cap
Auto Drain Valve
This is used to automatically drain off excess water from the line when water is turned off.
The drain valve should be threaded into the last fitting of the mist line to reduce calcium
build-up in the nozzles. If there are multiple elevation changes, more than one drain valve
may be needed. These should be installed at the lowest points in your system.
Nozzle Extensions
4 in. Nozzle Extensions, (Item #10056H) can be utilized to extend nozzle away from fitting and
allow easy, versatile direction of mist.
Filters
(1) T Filter attaches directly to 3/4 in. hose faucet and protects nozzles from clogging by
filtering solid sediments before they pass through to the mist line.
(2) A Calcium Inhibitor Filter (Item # 10109) filters solid sediments and reduces mineral
deposit build up. (See Accessory List)
Use and Placement of Mist System Components
Before Mounting Your Mist System
Flush Mist Line
Before screwing nozzles into fittings, connect Hose Adapter to garden hose or faucet. Turn
on the water for a few minutes to flush out any dirt or debris from within the mist line. Turn off
the water and place nozzles in fittings (hand tighten only).
Pressure Test Mist System
With mist line still attached to water source, turn water on to test line pressure and fittings
for proper installation. Water will shoot from the drain valve when the water is turned on.
Do not be alarmed. The valve will shut off when the line is pressurized. Inspect each fitting.
Should any fitting leak, see the section on Troubleshooting for instructions.

Mounting Your Mist System
Make sure your Mist System has been flushed and pressure tested prior to mounting mist line.
Step 1
It is recommended that the system be mounted on the bottom of the supporting
structure. Begin by placing one of the 3/8 in. hanging clamps over the mist line 3 in. from the
first nozzle. The first fitting in your Mist System should begin 2 ft. from the house on a patio
cover. Hammer the clamp into the BOTTOM of the support beam or fascia board.
Step 2
Continue placing a hanging clamp 3 in. on each side of each fitting and hammering
in place. Pull tubing slightly while applying each clamp to avoid sagging in mist line.
Step 3
Connect the T Filter to the water source, then connect the feedline to the T Filter
and turn on the water to operate mist system.
Maintenance
The following recommendations will assist you in maintaining your mist nozzles and
preventing unnecessary clogging.
Draining Water from Mist Line
Whenever the mist system is not in use the residual water should be drained to minimize
nozzle clogging. If your system has had an Auto Drain Valve installed correctly no additional
steps are required after turning off the water. If an Auto Drain Valve has not been installed,
detach system at the water source and allow the water to drain completely.

Nozzle Cleaner (Model #10103)
Periodically clean the nozzles in system. See bottle for instructions.

Filter can also be used to prevent any solid sediments from passing from
the water source to the nozzles and helps reduce calcium build up on nozzles.
Flushing System
Always remove nozzles at the end of the summer season. Before reinstalling your nozzles
flush the system for 5 minutes. To keep the mist line free from debris in the off-season install

Nozzle Plugs (Item #10107) in place of nozzle. You should also flush the
system if it has been idle for longer than a month.
Troubleshooting
Leak in Tubing
If a leak occurs in the actual tubing itself (not the point where the tubing meets the fitting),
the tubing must be replaced where the leak has occurred.
Leak in Nozzle
Make sure the nozzle is sufficiently tightened into place. HAND TIGHTEN ONLY - DO NOT
USE TOOLS. Check to make sure the nozzle O-ring is in place. Also, nozzle may be clogged,
which can give the appearance of leaking or dripping. Clean with nozzle cleaner.
