INSTRUCTIONS
INSTALLATION PROCEDURE
A. Read and follow all instructions contained in this manual before
installing, operating, and maintaining this equipment. Failure to do so
could void the warranty, damage the equipment, or cause severe injury
or death.
B. Review Figure 2 for NGS 1000 scrubber component nomenclature.
Refer to Figure 3 for mounting dimensions and NGS scrubber general
arrangement. Install scrubber units only in vertical position shown.
C. Install the NGS 1000 scrubber using appropriate mounting hardware.
Optional (factory supplied) universal mounting brackets are available.
D. Relieve and block all pressure before installing, maintaining, or
dismantling the NGS 1000 scrubber.
E. Remove the NGS 1000 scrubber cover (Item 3). Carefully inspect the
spring (item 6), the o-ring (item 8), and the cover/housing threads.
Remove any dirt, contaminants, or residue from the cover/housing
threads prior to final assembly.
F. Read the label on the NGC Natural Gas Cartridge (Item 1) then remove
the cartridge from the factory-sealed bag. Ensure the contents of the
NGC cartridge are never exposed to water.
G. Insert the NGC cartridge (Item 1) into the scrubber housing (Item 2).
To help with this process you may choose to insert a sheet of rolled
paper or transparency into the scrubber housing (Item 2) prior to
inserting the NGC cartridge. Remember to remove the paper or
transparency once the NGC cartridge has been installed.
H. Re-install the NGS cover (Item 3) using a wrench (see Table 3(b) for
hex size) and ensure the cover has completely bottomed out and there
is zero gap between the cover and the housing. CAUTION: DO NOT
OVERTIGHTEN the cover or thread damage may occur. Contact
the factory if threads are damaged, corroded, stripped, or galled.
I. Ensure all fittings are installed and sealed in accordance with the
manufacturer's specifications.
J. Verify that the drain cock (Item 7) is in the fully closed position
(clockwise hand tight) before pressurizing the system.
MAINTENANCE PROCEDURE
I. Refer to Table 4 to determine the suggested change-out
frequency for your Cata-Dyne™ heater application.
II. Relieve and block all pressure before installing, maintaining,
or dismantling the NGS 1000 scrubber.
III. Release and contain any residual water/ contaminates from the
drain bowl by opening the drain cock (Item 7) counterclockwise.
IV. Repeat step E of the Installation Instructions.
V. Remove and properly dispose of used or contaminated cartridges
in accordance with all applicable government regulations.
VI. Repeat steps F through J of the Installation Instructions.

WARRANTY
Table 4 shows cartridge change-out frequencies in days for each model
heater and gas scrubber for H S and moisture.
2
To determine the cartridge change-out frequency in days for other H S or
2
moisture concentrations, use the formulas provided in the following
examples:
Example 1: Sour Gas H S
2
Your installation has a Cata-Dyne™ heater, model
WX 12 x 24, 8,000 BTU/hr (2.343 kW/hr) natural gas using a model NGC-
4 cartridge.
·The concentration of H S in your gas supply is 25 ppm.
2
·The change-out frequency for 10 ppm is 87 days (derived from
Table 4).
·COF = 87 days x 10ppm / 25 ppm = 34.8 days.
·The NGC-4 scrubber cartridge should be changed once every
35 days.
Example 2: Moisture
Your installation has a Cata-Dyne™ heater, model
WX 12 x 24, 8,000 BTU/hr (2.343 kW/hr) natural gas using a model NGC-
4 cartridge.
·The concentration of moisture in your gas supply is 25 ppm.
·The change-out frequency for 50 ppm is 69 days (derived from
Table 4).
·COF = 69 days x 50 ppm / 25 ppm = 138 days.
·The NGC-4 scrubber cartridge should be changed once every
138 days.
