GUIDE
Model 1700TM
The patented Model 1700TM was
designed for removing condensate from
compressed air systems. Since it is total-
ly pneumatic, it does not require any
electricity and can be easily installed
using simple piping connections at any
point in a system including remote loca-
tions. It can handle pressures up to 170
PSIG and liquid temperatures up to
170OF. It has 1/2” NPT inlet and outlet
ports and a full 1/2” smoothly contoured
condensate flow path. The industrially
robust, highly reliable Model 1700TM has
few moving parts and at 21 pounds, can
stand up to the most demanding applica-
tions with minimal maintenance.

Before installing the Drain-All, Inc.
Model 1700TM, a review of the following
items will help make the right decision
regarding options which could be used to
ensure long-term maintenance free oper-
ation.
RUST AND SCALE
Even though the Drain-All, Inc. Model
1700TM is designed for handling rust and
scale, it is recommended that the system
be blown down after all piping is
installed and before the Model 1700TM is
connected to the piping. The Model
1700TM, with a large, smooth, liquid flow
path, easily handles contaminates in the
liquid once the system is in operation. If
there is excessive rust and scale on a con-
tinuous basis, consider using the Rust
HandlerTM designed for compressed air
systems that have extremely heavy
amounts of rust and scale.
CONTROL AIR & BALANCE LINE
The control air line provides air through
the sealed center tube to operate the air
cylinder. Clean dry air should be used for
this control air supply. The balance line
provides a means to handle the displaced
air from the reservoir as the liquid enters
the reservoir. The control air line and the
balance line are two separate lines which
have nothing in common with each other
and should never be connected to each
other in any way. Do not tie them togeth-
er with a tee fitting.
CONTROL AIR
Control air pressure requirements vary by
product and must be regulated within
specifications provided in the product’s
Installation Guide. If the specified pres-
sure for control air cannot be supplied in
your application, contact your distributor
for information on control air options
offered by Drain-All, Inc. to accommo-
date your available control air pressure.
BALANCE LINE
The balance line must have either (1)
exactly the same pressure as the vessel
being drained or (2) slightly less pressure
than the vessel being drained.
The same pressure is achieved when the
balance line is tied back into the vessel
being drained, such as connecting the
balance line at a tee fitting on the vessel’s
pressure gage or access port. A slightly
lower pressure may be achieved by locat-
ing the balance line connection on the air
header pipe a few feet downstream from
the vessel being drained. When hooking
the balance line to an air header, connect
it to the header prior to any other vessel
attached to the header.
If there is absolutely no place to connect
the balance line into the air system, or if
a temporary installation is to be made
while waiting for the next shutdown to tie
in the balance line, the balance line can
be vented to atmosphere. Install the nee-
dle valve that comes as a component of
the installation kit into the port on top of
the Model 1700TM where ''Balance Line''
is indicated. Then follow the start-up
instructions for adjusting the opening of
the balance line needle valve. There will
be very little air loss to atmosphere.
NO MANIFOLDS
There cannot be multiple system drains
through a manifold to one Model 1700TM.
This will not work because all system
drains will not be of the same pressure.
Therefore, the liquid from the higher
pressure drain lines will bypass the
Model 1700TM and flow backwards up the
lower pressure drains. Installing check
valves on system drains is not a solution
because pressure variations which inhibit
proper operation will still be present.
Proper installation of the balance line is
not possible with multiple drains hooked
up through a manifold.
CORROSION
There are Drain-All, Inc. products avail-
able which include corrosion resistant
coatings and materials. If the application
environment is highly corrosive, check
these products and options to determine
if they should be specified. Also available
are Drain-All, Inc. products which handle
higher pressures and temperatures.
INSTALLATION STEPS
1. Prior to installing the Model 1700TM,
blow down the vessel being drained to
remove excessive rust, scale, and dirt
knocked loose during piping installation.
2. Remove the Model 1700TM from the
box and set it in an upright position
where it will be connected. Most Drain-
All, Inc. products do not have to be
secured. Larger volume and higher pres-
sure products may require some form of
movement restraint. To ensure proper
operation in all installation layouts, the
top of the Model 1700TM should be lower
than the bottom of the vessel being
drained.
3. Using 1/2” pipe, connect the vessel
being drained to the 1/2” liquid inlet on
the base of the Model 1700TM. Be sure to
install a shut-off valve and a bypass valve
between the vessel being drained and the
Model 1700TM. This will allow easy
removal of the Model 1700TM "on the
run" during any preventive maintenance
activities. After installing the piping,
close the inlet shut-off valve.
4. Using 1/2” pipe, connect the Model
1700TM discharge outlet to a sealed drain
pipeline or enclosed/covered trough. The
discharged liquid is under pressure and
can splash back if directed downward
toward the bottom of a simple, shallow,
open trough-type floor drain.
5. Connect the balance line from the
Model 1700TM to the appropriate connect-
ing point on the vessel being drained
using the tubing and needle valve provid-
ed in the installation kit. After installing
the balance line, close the balance line
needle valve.
6. Using the tubing and needle valve pro-
vided in the installation kit, connect the
control air supply line to the control air
filter inlet on the Model 1700TM. Always
use the cleanest and driest air possible to
ensure long term maintenance free oper-
ation. After connecting the control air
line, close the control air needle valve.
INSTALLATION
Page 2022802 Model 1700-IG

START-UP
1. Close control air line and balance line
needle valves as well as inlet isolation
shut-off valve.
2. Bring up system pressure.
3. Fully open control air needle valve.
Check for leaks in control air line. Push
the “Push to Test” button on top of the
Model 1700TM to verify the air cylinder
strokes, opening the discharge ball valve.
Leave control air needle valve open.
4a. Applications where the balance line
is connected back to vessel being
drained. Fully open the balance line nee-
dle valve. Check for air leaks on balance
line and fittings. Leave balance line nee-
dle valve fully opened. The needle valve
can be used as an isolation shut-off valve.
4b. Applications where the balance line
needle valve is vented to atmosphere
or connected to a header pipe leaving
the vessel being drained. Open the bal-
ance line needle valve only enough to
ensure a small amount of air can flow
through it. This will be adjusted in a later
step.
5. Gradually open the inlet isolation shut-
off valve to the full open position to
allow liquid to enter the Model 1700TM.
The reservoir will fill until the float is
raised to the upper position actuating the
control circuit extending the air cylinder
and opening the ball valve. Once the dis-
charge starts, the liquid level in the
Drain-All reservoir begins to lower. This
lowers the float back to its original posi-
tion which deactivates the control circuit
closing the ball valve.
6a. Applications where the balance line
needle valve is vented to atmosphere
or connected to a header pipe leaving
the vessel being drained. With liquid in
the reservoir and the liquid discharge ball
valve in the closed position, close the
balance line needle valve. As you slight-
ly open the balance line needle valve,
look into the translucent sleeve just
above the inlet port and look for a trickle
of small bubbles. Continue to open the
needle valve until you see these bubbles
indicating a proper setting for the balance
line needle valve. Remember that bub-
bles will only be seen if there is a pres-
sure differential (when balance line is
vented to atmosphere or to a header leav-
ing the vessel being drained).
6b. When the balance line is connected
back to the vessel being drained, there is
no pressure differential between the inlet
and balance line and there will be no
bubbles in the liquid. In this application
keep the balance line needle valve in this
connection fully open. The top of the
Model 1700TM must be below the bottom
of the vessel being drained.
7. Once properly installed, no further
adjustments to the Model 1700TM are nec-
essary. The Model 1700TM is fully auto-
matic, discharging on demand as needed
when liquid accumulates.
TROUBLESHOOTING
1. Water does not enter.
A. Balance line isolation shutoff valve is
closed which does not allow liquid to
enter the Model 1700TM.
Solution: Adjust balance line needle
valve per installation instructions.
B. Liquid inlet shut-off valve is closed.
Solution: Fully open liquid inlet shut-off
valve.
C. Vessel drain, and/or pipe from vessel
drain to Model 1700TM inlet is plugged.
Solution: Clear obstruction.
D. Location of balance line connection
causes higher balance line pressure than
liquid inlet pressure. Model 1700TM is
“back flowing”.
Solution: Refer to installation instruc-
tions for proper balance line installation.
2. Fills and will not drain.
A. Control air line needle valve is closed,
or not fully open.
Solution: Fully open control air needle
valve to full open.
B. Lack of adequate air pressure on con-
trol air line.
Solution: Provide more than the mini-
mum required PSIG to control air line
connection per the product specification.
If there is not enough control air pressure
available, there are lower control air
pressure options available - contact your
distributor for details.
C. Hole in valve stem clogged.
Solution: Clear obstruction. Do not alter
hole diameter.
D. Filter element clogged or dirty.
Solution: Replace part.
3. Discharge ball valve stays open.
A. Center tube magnet installed upside
down, i.e., north and south poles
reversed.
Solution: Reinstall center tube magnet
rotating it 180 degrees, end for end.
B. Bleed hole for air cylinder clogged.
Solution: Clear bleed hole on side of air
cylinder located on opposite side from
control air connection to the cylinder. Do
not alter hole diameter.
C. Center tube magnet stuck or not prop-
erly sealing against valve stem. This can
result from excessive oil and water con-
taminates allowed to get into the control
air lines and then into the center tube,
thereby coating the center tube magnet
and causing it to stick.
Solution: Clean center tube and center
tube magnet and reassemble. Also, if
possible, connect the control air line to a
clean dry air source which will prevent
reoccurrence.
4. Excessive bubbling action in reser-
voir.
A. Air leak in balance line and/or fittings.
Solution: Refer to installation instruc-
tions and start-up procedures.
B. Balance line needle valve opened too
far.
Solution: Adjust balance line needle
valve per installation instructions.

PRODUCT TECHNOLOGY
HOW IT WORKS
Page 5
FIGURE 1: START OF CYCLE
The float (1) with a magnet molded in (2)
is sitting on the base and is at the lowest
level. The float magnet exerts a magnetic
force repelling the center tube magnet (3)
upward, holding it seated against an ori-
fice in the lower end of the valve stem
(4). This retains the control air coming in
through the control air filter (5) in the
center tube (6). The control air circuit
including the center tube magnet and
valve stem are isolated from the liquid
held in the reservoir (7). The air cylinder
(8) is in the home position and the dis-
charge ball valve (9) is closed.
There is always a residual amount of liq-
uid (10) left in the bottom of the reservoir
after each discharge cycle. The Model
1700TM stops discharging before all accu-
mulated liquid is removed providing a
liquid seal that conserves expensive com-
pressed air. Liquid (11) flows through the
inlet port (12) and into the reservoir to
start the fill cycle. Liquid continues to fill
the reservoir until the float has displaced
enough liquid to become buoyant and the
float pops upward to the upper position
shown in Figure 2.
FIGURE 2: START OF DISCHARGE
The liquid flows in and raises the float to
its highest position as shown. The float
magnet is raised up past the center tube
magnet and repels the center tube magnet
downward opening the orifice in the
valve stem. This allows the control air
held in the center tube to flow through the
control air circuit to the actuating cylin-
der. The actuating cylinder extends and
opens the ball valve starting the discharge
of accumulated liquid.
When the correct amount of liquid has
been discharged, leaving a liquid seal in
the reservoir, the float has been lowered
to a point where the float magnet is below
the center tube magnet. In this position,
the float magnet repels the center tube
magnet back upward against the valve
stem orifice, which seals off the control
air flow to the actuating cylinder. The
cylinder has a spring which then returns
the cylinder to its home position, closing
the discharge ball valve. The discharge is
stopped as shown in Figure 1 and the fill
cycle repeats.
THE BALANCE LINE PORT
The balance line port is a hole through
the head of the Model 1700TM that goes
into the reservoir. This port allows the air
trapped in the top of the reservoir to
move out of the reservoir to allow liquid
to enter the reservoir through the inlet
port. If there were no balance line port, as
liquid entered the reservoir under pres-
sure, the air trapped in the top of the
reservoir would be compressed until it
was the same pressure as the liquid com-
ing in and the unit would stop filling.
There are three methods of connecting to
the balance line port. The most effective
is to connect it back to the vessel being
drained as shown in the illustrations
above. In this configuration, the reservoir
is at the same pressure as the vessel being
drained and the liquid is filling by gravi-
ty. In this case, the top of the Model
1700TM must be lower than the bottom of
the vessel being drained. The balance line
can also be attached to a header pipe
leaving the vessel being drained or vent-
ed to atmosphere using a needle valve.
Venting to atmosphere uses very little air
if the needle valve is adjusted properly.

Where should a Drain-All be installed?
At liquid accumulation points within a
system at compressors, air receiver tanks,
intercoolers, aftercoolers, dryers, separa-
tors, filters and drip legs.
Is this an oil-water separator?
No. Drain-All is a liquid drain and it will
drain oil, water, and particulates from the
compressed air system. Once this is
accomplished, the discharge should be
piped to an oil-water separator for final
processing.
Does this replace a dryer?
No. Drain-All works in conjunction with
a dryer. Dryers typically convert water
vapor in the compressed air into liquid
which is usually discharged through a
small automatic drain device integral to
the dryer. These small automatic drains
are often prone to clogging and failure.
When this occurs, such drains are nor-
mally replaced with Drain-All units
which do not clog. A dryer prepares the
moisture for removal from the system by
condensing it. It is the job of the reliable
Drain-All to ensure that the liquid is
actually discharged from the air system.
Is it mandatory to use a balance line?
Yes. The balance line provides a means to
handle the displaced air from the reser-
voir as the liquid enters the reservoir.
What is the capacity?
In each application, based on pressures
and piping layout for that application, a
Drain-All model will eject a specific
amount of liquid on each cycle. This
varies by model and application.
What size compressor can it handle?
There are Drain-All models that will
function effectively on any size compres-
sor, compressed air system, atmospheric,
or vacuum system. Provide your distrib-
utor with specifications on the pressure
and capacity of liquid you need to handle
and an appropriately sized Drain-All can
be selected for your application.
Can one Drain-All be used to drain
multiple tanks and/or compressor sys-
tems?
No. They will not all be of precisely the
same pressure level and the liquid would
accumulate in the lowest pressure drain
or system thereby bypassing the Drain-
All. Also, the use of check valves in mul-
tiple drains to one Drain-All installation
will not make this work properly.
Always install one Drain-All for each
item of equipment to be drained.
Can a Drain-All be used in systems
with pressure greater than 170 PSIG?
Yes. Higher pressure models are avail-
able. If the control air comes from higher
pressure systems, a pressure regulator on
the control air line may be used and set at
the proper control air pressure or option-
al control air components can be ordered
to accommodate higher pressures.
Can the balance line and the control
air line be hooked together via a tee
connection?
No. Do not do this. Each of these air
lines has its own specific purpose and
should never be tied together. The con-
trol air should be the cleanest driest air
available since it supplies air to the con-
trol circuit to operate the pneumatic actu-
ating cylinder which functions best and
lasts longer if clean dry air is used.
The balance line allows the air in the
reservoir to move out leaving room in the
reservoir for the incoming liquid. This air
contains moisture that would be drawn
across a tee fitting tied to the control air
line and be pulled directly into the con-
trol air circuit, which can damage control
air pathways and the air cylinder.
Is there only one model Drain-All?
No. There are models for a wide range of
special applications. Dimensional alter-
ations, design changes, component
options and special materials or coatings
are used in models to withstand high tem-
peratures and highly corrosive environ-
ments as well as accommodate high vol-
ume discharge requirements.
What if the system has an abundance
of metallic trash?
Before installing the Drain-All, blow
down the system being drained to elimi-
nate as much existing loose scale as pos-
sible. The large, smoothly contoured flow
paths in Drain-All units handle normal
levels of debris found in most applica-
tions. Should there be an excessive
amount of debris such as heavy rust, ask
your distributor about Drain-All’s Rust
HandlerTM Model designed for that kind
of severe duty.
How can the Drain-All be used as an
instrument to gather data on conden-
sation in a compressed air system?
With the use of Drain-All’s optional
cycle counter, the Drain-All can provide
accurate data on the amount of liquid that
a compressed air system generates. This
is very useful when buying new com-
pressed air system equipment because a
Drain-All with a cycle counter is a
benchmarking instrument. Since the
Drain-All discharges the same amount of
liquid on every cycle, knowing the num-
ber of cycles over a specific period of
time under specific temperature and
humidity conditions provides the ability
to track liquid production. This bench-
marking can be correlated to ongoing
changes in ambient temperature and
humidity conditions to identify variances
in liquid production indicating changes
which need investigation. Too few cycles
would mean not enough liquid is reach-
ing the Drain-All and should be investi-
gated. Too many cycles would mean too
much liquid is being made or too much
liquid from somewhere is reaching the
Drain-All and should be investigated.
Knowing the amount of liquid a system
produces is also essential for properly
sizing oil-water separators.

CLOGGED DRAINS
Other drain devices with small orifices
and poppet style valves are prone to clog
when solid debris is present. Each Drain-
All has a large, smooth liquid flow path
and discharge port as well as a heavy
duty shear action ball valve designed to
alleviate this problem.
ELECTRICITY
Timer valves require electricity. There is
a cost for installing and maintaining the
electric outlets they require as well an
ongoing operating cost of electricity year
after year. Drain-All requires no electric-
ity to operate since it is totally pneumatic
and can be easily installed at any point
along the compressed air system provid-
ing low cost installation and ongoing
operation.
RELIABILITY
Drain-All’s cycling is controlled by a
patented magnetic interaction with a
totally pneumatic control circuit. While
other pneumatic drains have a complex
lever action “toilet bowl” type internal
float with many parts, there are few mov-
ing parts in the Drain-All. Since the
Drain-All is totally pneumatic, it is not
affected by power outages or the other
vulnerabilities of electrical devices such
as timer solenoid valves, motorized ball
valves or electrically operated float traps.
BYPASSED DRAINS
Smaller drains become plugged so often
that cleaning them out becomes a very
labor intensive operation. To avoid con-
stant cleaning, there is a temptation to
bypass the inadequate drain and crack
open a manual bypass valve causing it to
drain constantly thus causing a constant
flow of wasted compressed air. Drain-
All’s anti-clog design eliminates the
temptation to bypass the drain.
SYSTEM BLOW DOWN
Manually operated drains, timer solenoid
valves, motorized ball valves or electri-
cally operated float traps blow away large
quantities of expensive compressed air.
Manually operated drains waste consid-
erable compressed air because most oper-
ators feel it is necessary to have the drain
open an extended period of time in order
to get all the liquid out. Timer valves are
almost always set to be open longer than
necessary in order to get all of the liquid
out and this also passes large quantities of
compressed air down the drain. Drain-
All avoids this waste of compressed air
and the resulting pressure drop in the
compressed air system by maintaining a
liquid seal in the bottom of the Drain-
All’s reservoir between each cycle.
AMOUNT OF LIQUID
Manual draining and timer valve draining
do not provide any information on the
quantity of liquid being produced in the
compressed air system.
Each Drain-All model discharges a spe-
cific amount of liquid on each cycle in a
given application. With the addition of a
Drain-All cycle counter on the Drain-All
unit, it is easy to track how much liquid is
produced over any period of time. This is
particularly important for benchmarking
system equipment performance and per-
forming trend analysis. For example, it is
essential to know the quantity of liquid
produced by a compressed air system to
properly size oil-water separators.
The counter coupled with a Drain-All
unit is an instrument. Once installed, it
provides tracking of the number of cycles
for periods of time at different ambient
temperature and humidity conditions.
This data can be plotted on a chart.
During operations thereafter, a check on
the number of cycles per time period of
actual operation compared to the chart
for a given temperature and humidity will
show if the correct amount of liquid is
being received by the Drain-All. Too
many cycles compared to the chart indi-
cates excessive liquid is being produced
somehow and should be investigated.
Too few cycles indicates that not enough
liquid is being produced and this too
should be investigated.
OVER-DRAINING
Manual drain valve operation and timer
valves are usually set for overkill in fre-
quency and duration of drainage times in
order to be certain that no liquid accumu-
lates in the system. This results in waste
of expensive compressed air. Drain-All is
demand activated and drains only when
the liquid reaches the predetermined trig-
ger point. The Drain-All does not over-
drain or blow down the system.
UNDER-DRAINING
Timer drains must be preset to establish
the frequency and duration of drainage.
The settings are vastly different in peri-
ods of high humidity from what they
would be in periods of low humidity. It is
common for this adjustment to be over-
looked in the transition from winter to
summer. Therefore, the settings are inad-
equate to handle the high summer quanti-
ties of liquid which results in excess liq-
uid accumulation in the compressed air
system. This liquid often backs up and
can cause damage to dryers, compressors
and hand tools that is expensive to repair.
The Drain-All is designed to cycle as
needed when liquid accumulates and
requires no adjustments from season to
season.
LIQUID REMOVAL
The air pressure in the system being
drained forces the liquid out of the Drain-
All reservoir. Because the power of the
air system is behind it, the discharge can
be directed upward, to a containment
vessel, oil-water separator or an overhead
discharge piping system.

Automatic
No timers, work on demand
Pneumatic
Totally air operated
Energy Efficient
Save valuable system pressure
Reliable
Robust, with few moving parts
Easily Installed
Simple pipe connection
Adaptable
Special models for all applications

In the drawing below, there is a dotted line
indicating the level of the trigger level of the
trap. This is the height the condensate must
reach in the trap to start the discharge cycle.
When the balance line port is connected
back to the vessel or header pipe, as
shown in the drawing above, the trap is
filling by gravity. In these applications the
bottom of the vessel must be higher than
the top of the trap so that the condensate
flows by gravity down and out of the ves-
sel into the trap.
When the bottom of a vessel being
drained is lower than the trigger point in
the trap, as shown in the drawing to the
right, do not connect the balance line port
to the vessel or header pipe.
In the drawing to the right, if the balance
line were connected to the vessel or head-
er pipe, the condensate would be filling
the trap by gravity. With the bottom of the
vessel being lower than the top of the trap,
this would result in condensate backing up in
the vessel to the same height of the conden-
sate in the trap. When the condensate reached
the trigger level in the trap, shown by the dot-
ted line, the condensate would also reach the
same height in the vessel (the same dotted
line).
In an application where the bottom of the
vessel is lower than the top of the trap, the
balance line must be vented to atmos-
phere. Venting a small amount of air from
the trap reservoir to atmosphere results in
a pressure differential in the trap reser-
voir. This allows the pressure in the ves-
sel to push the condensate downward, out
of the vessel, and up into the trap. This
achieves proper filling of the trap while
removing all condensate from the vessel.

INSTALLATION LOCATIONS
Method -1
Connect the balance line port to the vessel
producing the condensate. This is the pref-
ered method since it is a closed-loop arrange-
ment. In the first four applications above, the
balance line is connected back to the vessel
that is producing the condensate. The pres-
sure on the incoming condensate to the trap
and the pressure in the balance line are the
same and the trap is filling by gravity. For this
method, the top of the trap must be below the
bottom of the vessel being drained.
Method -2
Connect the balance line port to the head-
er pipe leaving the vessel producing the
condensate. This is an alternate method to
Method-1 when there is no convenient loca-
tion to connect the balance line to the vessel.
This is shown above in the drip leg applica-
tion. In the case of a dryer, however, connect-
ing the balance line to the header pipe leaving
the dryer essentially results in a bypass of the
dryer function. The condensate from the
dryer would have a path up the balance line
and back into the flow of dry air leaving the
dryer. That would not be desirable.
Method -3
Vent the balance line port to atmosphere
using a needle valve inserted in the balance
line port and slightly opened. This can be
used on any application but must be used
when the bottom of the vessel is lower than
the top of the trap. The needle valve should
be opened slightly to a point where only a
small amount of air can be felt leaving the
needle valve. This method provides a pres-
sure differential in the trap reservoir and con-
densate is blown into the reservoir instead of
filling by gravity.
VESSELS WITH BOTTOM LOWER THAN THE TRAP’S TRIGGER LEVEL
THERE ARE THREE METHODS USED TO CONNECT THE BALANCE LINE PORT
1. Connect balance line to vessel being drained, to header leaving vesssel being drained, or vent to atmposphere - do not manifold balance lines together.
3. Bring control air from clean dry source downstream of dryer if possible, can manifold control air lines together.
2. Balance line balances reservoir of trap to vessel being drained. Control air operates air cyclinder. These two should not be connected together.
