FILTER MAINTENANCE INSTRUCTIONS

1. The following simple maintenance procedures will ensure maximum FLO‑DRI filtering efficiency and a longer filter life.
2. FLO‑DRI cartridges should be examined frequently until a pattern of usage is established.
3. Failure to replace cartridges in an expedient fashion may result in excessive pressure drop and the possibility of contaminant carry over. Refer to the FLO‑DRI Cartridge Change-Out Calculator available on Thermon’s website for recommended change out schedules. This calculator allows the user to determine an accurate cartridge replacement schedule based on their specific application. If the calculator is unavailable, replace cartridges every 30 days or when the cartridge appears to be contaminated.
4. Do not subject the unit to vapours or liquids from synthetic solvents, acetone, methanol, esters, lacquer thinners, phosphates, etc.

TO CHANGE FLO-DRI CARTRIDGES

WARNING. Never replace filter cartridge when the unit is under pressure. Always follow safe work procedures when working with high pressure.

1. Close inlet, wait for unit to vent, then close the outlet isolation valve to the FLO-DRI filter.

2. To vent filter, open drain cock. Make certain filter is COMPLETELY VENTED and under NO pressure prior to removing the top end cap.

3. To remove the end cap: depress, turn counter clockwise and pull out. DO NOT LOOSEN CASTLE NUTS.

4. Inspect filter media. Replace when completely saturated, or earlier.
   WARNING. If is essential to positively confirm close of top cap prior to re-pressurizing system.

5. Insert two new FLO-DRI cartridges (sewn end down) into the filter unit.

6. Replace end cap, close drain cock and open isolation valves before returning FLO-DRI unit to service.

CHANGE-OUT SCHEDULE FOR FLO-DRI

Table 5, page 6 shows cartridge change-out frequencies in days for each model heater and gas scrubber for H2S and moisture.
To determine the cartridge change-out frequency in days for other H2S moisture concentrations, use the formulas provided in the examples.

Table 5 – Flo-Dri Cartridge Change Schedule in Days

Example 1: Sour Gas H2S

Your installation has a Cata‑DyneTM heater, model WX 12×24, 10,000 Btu/hr (2.928 kW/hr) natural gas using a model FloDri-10MS cartridge.

• The concentration of H2S in your gas supply is 25 ppm.
• The change-out frequency for 10 ppm is 70 days (derived from Table 5).
• COF = 56 days x (10 ppm/25 ppm) = 22 days
• The FloDri-10MS scrubber cartridge should be changed once every 22 days.

Example 2: Moisture

Your installation has a Cata‑DyneTM heater, model WX 12×24, 10,000 Btu/hr (2.928 kW/hr) natural gas using a model FloDri‑10MS cartridge.

• The concentration of H2S in your gas supply is 25 ppm.
• The change-out frequency for 50 ppm is 45 days (derived from Table 5).
• COF = 45 days x (50 ppm/25 ppm) = 90 days
• The FloDri-10MS scrubber cartridge should be changed once every 90 days.
