I. GENERAL SAFETY INFORMATION
CAUTION
A. Pressurized devices
This equipment is a pressure containing device.
• Donotexceedmaximumoperatingpressureasshownon
equipment serial number tag.
• Makesureequipmentisdepressurizedbeforeworkingonor
disassembling it for servicing.
B. During each operation of the drain a small amount of system
gas is discharged to atmosphere through the bleed hole in the
piston cylinder.
• Wherehazardousorexplosivegasesarepresentinthe
system, provisions for safe disposal of the discharge must be
provided.

III. INSTALLATION
IMPORTANT:
DO NOT use a wrench on the valve body of
the drain. Tighten using wrench flats on top
of drain only. The valve body should never be
turned once it is installed. If it is turned, the
float arm may become restricted and will not
operate.
B. Install drain vertically to ensure proper float
operation.
C. Connections:
1. Inlet line
a. Inlet line should slope downwardly
to drain inlet to allow condensate to
flow into the drain by gravity.
b. Strainers to protect the drain from
undue particulate contamination
andisolationvalvestopermitquick
and easy drain servicing are useful
additions to the inlet line.
c. The inlet pipe to the drain should
not be smaller than the inlet con-
nection so that drainage is not
restricted(avoidpiping“pockets”).
A. Preparation:
1. All Models: Remove inlet and drain
thread protectors.
2. Bottom Connection Models: Bushing
and compression fitting are shipped
loose in carton. Install these items
in fitting on top of drain before
installation. Refer to Figure 2.
2. Drain Line
While it is not always necessary, a drain
line is normally recommended in order
tokeepcondensatefromsprayinginto
the area in front of the discharge port.
NOTE: In many cases condensate
containsoil.Checkregulationsinyour
area for proper disposal methods for
oil contaminated condensate

adequate sump or floor drain,
preferably below the level of the
drain.
b. Do not put a valve in the drain line
or obstruct the discharge of the
condensate in any way (such as
withseverebendingofdrainline).
c. Drain discharges condensate at
system pressure; the drain line
should be anchored to prevent
movement.
3. Vent Line
Vent lines are required on all bottom
connection drains and on top connec-
tion drains only where upward sloping
inlet lines form a water trap.
a. Bottom connection drains: Bottom
inlet connection drains must be
vented by running 1/4" O.D. tubing
from the compression fitting on
the top of the drain to a place in
the system where there is pressure
equal to the pressure in the device
being drained. See Figure 3.
b. Top connection drains: It is
normally not necessary to vent
top connection drains. See Figure
4. However, if an upward sloping
drain line is unavoidable, a vent line
is necessary. See Figure 5.

*Drains are designed to operate at one discharge per minute for one year before servicing is required. Operation at more than one discharge per
minute may require more frequent servicing.
V. OPERATION
Positive discharge of condensate without loss of air.
LEVEL ACTUATED, PILOT CONTROLLED. . .
As condensate collects in the drain housing, a float (1) is held firmly in place
by a magnet (2). When the condensate level rises sufficiently, the buoyancy of
the float overcomes the holding force of the magnet and the pilot valve (3) trips
open.
POWER OPERATED. . .
When the pilot valve opens, compressed air enters air cylinder (4), forcefully
moving piston (5), which opens a large discharge port (6). Condensate is then
forced out of the discharge port. After the condensate has been discharged,
the float drops and pilot valve (3) closes. Compressed air in piston cylinder (4)
bleeds off through bleed hole (7). Air pressure in the housing then moves
piston (5) the opposite way, closing the discharge port and holding it securely
shutuntilthenextoperation.
Allmodelscanbemanuallydrainedanddepressurizedthroughmanual
drain (8).

VI. MAINTENANCE
A. Regular maintenance of the condensate
discharge drain is recommended. Flush
out accumulated sludge and dirt by
opening manual drain valve about once a
month.
B. Disassemble and service at least once a
year. Drains are designed to operate at one
discharge per minute for one year before
servicing is required. Operation at more
that one discharge per minute may require
more frequent servicing. (NOTE: Before
startingtheservicingprocedure,makesure

AUTHORIZATION FROM THE SERVICE DEPARTMENT IS NECESSARY BEFORE MATERIAL
IS RETURNED TO THE FACTORY OR IN-WARRANTY REPAIRS ARE MADE.
WARRANTY
The manufacturer warrants the product manufactured by it, when properly installed, operated, applied, and maintained in
accordance with procedures and recommendations outlined in manufacturer’s instruction manuals, to be free from defects in
material or workmanship for a period of one (1) year from the date of shipment to the buyer by the manufacturer or manufac-
turer’s authorized distributor, or eighteen months from the date of shipment from the factory, whichever occurs first, provided
such defect is discovered and brought to the manufacturer’s attention within the aforesaid warranty period. The manufacturer
will repair or replace any product or part determined to be defective by the manufacturer within the warranty period, provided
such defect occurred in normal service and not as a result of misuse, abuse, neglect or accident.
The warranty covers parts and labor for the warranty period. Repair or replacement shall be made at the factory or the instal-
lation site, at the sole option of the manufacturer. Any service performed on the product by anyone other than the manufactur-
er must first be authorized by the manufacturer. Normal maintenance items requiring routine replacement are not warranted.
Unauthorized service voids the warranty and any resulting charge or subsequent claim will not be paid. Products repaired
