Introduction
Thank you for purchasing the cyclone separator.
This product has been thoroughly inspected before being shipped from the
factory. When the product is delivered, before doing anything else, check the
specifications and external appearance to make sure nothing is out of the
ordinary. Also be sure to read this manual carefully before use and follow the
instructions to be sure of using the product properly.
This separator is a welded-unit construction cyclone separator that uses
centrifugal force to separate condensate from air, steam or inert gases in
piping lines.
If detailed instructions for special order specifications or options not
contained in this manual are required, please contact for full details.
This instruction manual is intended for use with the model(s) listed on the
front cover. It is necessary not only for installation but for subsequent
maintenance and troubleshooting. Please keep it in a safe place for future

CAUTION
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
1. Before installation, be sure to remove all protective seals.
2. Before installing the product, blow out the inlet piping to remove any piping
scraps, dirt and oil. Close the inlet valve after blowdown.
3. Install the product at the point on the piping where the separation of condensate
will have the greatest effect on efficiency. For example, on a air, steam or inert
gas main or branch at the inlet of equipment requiring high-quality dry air, steam
or inert gases.
4. Install the product so the arrow on the product is pointing in the direction of air,
steam or inert gas flow.
5. The product should be inclined no more than 10° horizontally and front-to-back.
6. Install an air trap, steam trap or drain trap at the
condensate outlet. Use of the TLV free float type
trap is advised.
7. To facilitate inspection and maintenance, install
a union at the condensate outlet if threaded
connections are used, and ensure that there is
sufficient space for maintenance.
8. Open the inlet valve and outlet valves and check
to make sure that the product functions properly.
If there is a problem, determine the cause using the
“Troubleshooting” section in this manual.
Troubleshooting
When the product fails to operate properly, use the following table to locate the
cause and remedy.
Problem
Cause
Remedy
Water is mixed in with the
air, steam or inert gases
from the separator outlet
Air, steam or inert gas
flow velocity is too high
Take steps necessary to lower the
air, steam or inert gas flow velocity
Improper installation
Correct the installation
Tolerance Angle for Installation: 10°
Make sure the product is installed
with the raised lettering on
the body horizontal.
