Risk of personal injury.
Risk of property damage.
Except as otherwise specified by
the manufacturer, this product
is specifically designed for compressed air service and use with
any other fluid (liquid or gas) is a
misapplication. For example, use
with or injection of certain hazardous gases in the system (such as
oxygen or liquid petroleum gas)
could be harmful to the unit or
result in a combustible condition
that may cause fire or explosion.
Manufacturer's warranties are
void in the event of misapplication
and manufacturer assumes no responsibility for any resulting loss.
INSTALLATION
Risk of injury. Release all air pressure from system before servicing system. Be sure to read and
understand all Service Bulletins on
the separate components before
using the system. Use only specified DeVilbiss parts.
Certain solvents, paints and
chemicals may attack plastic
filter bowl and can cause bowl
failure. Do not use near these
materials.
NOTE
Risk of equipment damage! Do
not install your DAD unit where
it is subjected to sudden depressurization cycles exceedling
20 PSIG. Quick relieving air
solenoid valves, typical in some
spray booths, will eventually fail
pressure gauges and filters, and
produce desiccant "dusting".
To minimize sudden depressurization effect, replace the
existing solenoid with a "slow
closing solenoid valve". (One
source: Automatic Switch Co.)
Or, install an air adjusting valve
at the existing solenoids outlet.
1. See Plumbing Guide on page 6.
Be sure to read all "Warnings" and
"Cautions" in this manual and component manuals on the unit before
installation or using this equipment.
2. Install air drying system as close as
possible to the point where the air is
being used. Use template to position
location of system.
3. Install main air supply shut off valve
and piping union fitting (supplied by
user) upstream of air drying system
to allow maintenance to the unit.
4. Install unit with air flow through filter
in direction of arrow on top of filters.
5. Minimum 1/2" NPT piping is recommended. Avoid using fittings, couplings, etc. that restrict air flow.
6. Maximum inlet pressure and operating
temperature is: 150 PSIG (10.3 bar) and
a150° F (65.6°C)
7. Fill tank with desiccant materials (see
paragraphs 4, 5, 6 under "MAINTENANCE".
8. Two 6' lengths of vinyl tubing are
shipped loose with the system. Slide
over automatic drains which protrude
from bottom of the water/separator
and the oil coalescing filters. Place the
other end of vinyl tubing into appropriate receptacle. Prevent vinyl tubing
from becoming kinked which would
prevent free movement of liquids
discharged from the automatic drain.
9. An optional manual drain (HAF-11) can
be installed in place of the automatic
drains.
OPERATION
After the system is installed and ready to use:
1. Attach air hose(s) to outlet valve.
2. Open main shut-off valve upstream of
system.
3. Adjust regulator to desired setting by
turning "T" handle in or out.
4. Open ball valve to supply air to spray
guns or tool being used. With air
flowing, readjust air pressure at regulator if necessary.
5. After use, shut off ball valve and bleed
off residual air in hose.
MAINTENANCE
Risk of injury. Components under
pressure. Relieve air pressure before
performing any maintenance.
Certain solvents, paints and chemicals may attack plastic bowl and
can cause bowl failure. Do not use
near these materials. When bowl
becomes dirty, wipe only with
a clean, dry cloth. Immediately
replace any crazed, cracked, damaged or deteriorated plastic bowl
with a new plastic bowl. Reinstall
metal bowl guard.
Risk of injury. Do not place unit
in service without metal bowl
guard installed.
1. Check system at least once per shift to
insure proper drainage. Look for water
in the drain tubing.
2. Before performing maintenance on
system, close main shut-off valve
located upstream. Bleed off residual
air in system.
MAINTENANCE - DESICCANT DAD-1
NOTE
The desiccant tank contains an internal filter (DAD-8) at the inlet and
outlet. Be careful not to damage
them when changing desiccant.
1. Replace the desiccant when the hu-
midity indicator changes to a pink or
white color. Remove the pipe plug at the
bottom of the tank. Allow the material
to drain into a two (2) gallon or larger
container.
2. Once all the material has been removed,
replace the pipe plug (see "Note" following) and tighten (do not over tighten)
securely (air tight).
NOTE
Use PTFE tape on pipe plug threads
and all threaded fittings to facilitate
removal in the future. Do not use
loctite or any material that may
bond and make removal difficult.
Risk of injury. Only use a socket
wrench to remove the DAD-400
humidity indicator from the desiccant tank. Immediately replace
the DAD-400 humidity indicator
if damaged.
3. Replace the humidity indicator paper
(supplied with DAD-1 Dessiccant) by
removing the DAD-400 humidity indicator. Pry out the old paper and push
in the new paper (printed side facing
away from the glass).
4. Remove the pipe plug on top of the
unit.
5. Replace desiccant material, DAD-1
(19-0831). Two bags are supplied.
Hold bag pointed upward and cut bag
on dotted line. Grasp and hold bag
where cut and rotate over opening on
top of tank. Empty both bags into tank.
("Note" tank must be filled completely
to prevent damage to desiccant.)
6. Wrap pipe plug with 2 wraps of PTFE
tape. Replace the pipe plug and tighten
until air tight (do not over tighten).
7. The humidity indicator will return to a
blue color within five minutes.
8. The desiccant material should be disposed of properly.

HAF-18 Automatic Drain
NOTE
The automatic drain includes a float. If water gets
into the float, the automatic drain may not function
properly. Under normal conditions, water will not enter
the float. However, water can get in the float if the filter
bowl is washed with the drain installed or if air line
contamination causes the drain mechanism to stick.
A Properly Piped Shop Of Prime Importance for a
Premium Finish.
The bottom line in finishing is a quality paint job. Though on the
surface it may not seem a significant factor in your being able to
turn out a quality paint job, the plumbing of your shop air lines
is very important. Correct installation is necessary for the proper
performance of your equipment - for an uncontaminated air
supply and for sufficient pressure to your spray gun.
Correct airline piping is so important that this one factor alone
can reduce contaminates in your air supply up to 75%*. Reducing contaminates to the filter also reduces the frequency of filter
replacement, maintenance, and of course, reduces the risk of
contaminates to the paint supply.
Even the size of the pipe is critical. Did you ever have only 60 or
70 pounds of pressure at your spray gun when your compressor
should deliver 100 pounds? Using pipe that is too small in diameter
can cause this pressure drop.
For example, if an air compressor delivers 100 psi through a 100 ft.
pipe, 1/2" in diameter, there’s greater pressure drop than if a 3/4"
diameter pipe were used.
The following chart will help reduce pipe pressure drop.
You can confirm the automatic drain is not operating if the water
level in the plastic bowl is higher than the top of the automatic drain.
If the drain does not work properly, replace. It is not repairable.
Body Shop Air Line Plumbing Guide:
1
After leaving the air compressor, air line pipe goes straight up
the shop wall as high as possible. This helps prevent any water
from leaving the compressor and traveling through the pipe.
2
Horizontal pipes should slope back towards the compressor at
least 4” per 50 ft. As warm air leaves the compressor, it cools
and thereby condenses as it travels through the pipe. This wa ter vapor, a problem in itself, also can cause scaling and rust
inside the piping. The backward sloping of the pipe helps push
these contaminates toward the compressor drain.
3
Take-off comes from the top of the main air supply line at each
air drop. This reduces the risk of water and other contaminates
from traveling down the drop into the water separator.
4
Pipe diameter must be of sufficient size for the volume of air
being passed as well as the length of pipe used. This will
minimize pressure drop.
5
First air drop should be at least 25 ft. from the compressor
although 50 ft. is optimum. This allows the compressed air to
cool to room temperature so any condensation can occur
before it gets to the water separator.

Shut-off valve is installed before the point of use filter. This
allows air to be shut off for filter maintenance.
7
Pipe union installed before DAD-500 allows easy installation
and removal of the air drying system.
8
Point-of use filter (not shown) attaches to spray gun, order
HAF-507. Strongly recommended for eliminating any remain ing contaminates.
9
Drain Valves - The daily draining of the system at each outlet
disposes of the contaminants that build up in the air supply.
10
Drain the compressor trap daily if equipped with a manual drain.
Proper maintenance of the air compressor can reduce airborne
contaminants such as particules and oils, and reduce heat and
|operating cost. Check air filters, oil level and perform regular
maintenance per operators manuals.
Guidelines To Piping Your Shop
• Pipe slopes upward - recommend 4” rise in 50 ft.
9
• Minimum 25 ft. to first outlet (50 ft. optimum)
• Pipe size (see chart)
• Shut off valve before filter
• Drain daily
