Final (Post) Filter Cartridge
The final (post) filter cartridge reduces possible off characteristics from the system and the storage tank and provides cyst-rated
filtration of all product water, including by-pass and blending water. For steamer operation, a final (post) filter may not be required.
Thus, a by-pass plug is available. Choices of cyst-rated final (post) filters are listed in the table below. Choose a final (post) filter
according to the maximum possible demand flow rate when all downstream equipment is operating simultaneously. The TFS450 RO
filtration system supplied with both pre-filter and final (post) filter includes the HF-90 final (post) filter cartridge listed in the table.

a. Remove the red cap from the (post) filter cartridge.
b. Align the tabs on the cartridge to the openings in the final (post) filter head on the far right side of the TFS450 RO filtration
system and push up to insert the filter.
c. Turn the final (post) filter ¼ turn to the right until a click is heard, indicating that the filter is properly seated.
Reverse Osmosis Cartridges (2)
The two (2) RO membrane filter cartridges are identical. The drain lines to the bottom of each must be assembled properly or
the system will not perform properly.
• Install the left side cartridge first. Align the tabs and turn ¼ turn to the right to secure the cartridge into the head.
Remove the white plug from the bottom port and insert the reject tubing labeled “LEFT”.
• Install the second cartridge into the right-side head using the same procedure. Remove the white plug from the bottom
port and insert the tubing labeled “RIGHT”.
IMPORTANT NOTE: Double check the fittings into the positions labeled “LEFT” and “RIGHT”. Proper operation of the system
depends upon the correct installation of these two connections.
Start-Up Procedure
At startup, the procedures outlined below must be completed in the sequence:
• Measure and Adjust tank Air Charge
• Adjustment of TDS (Total Dissolved Solids) by Setting the Blending Valve
• Automatic Bypass Pressure Adjustment
Tank Air Charge Adjustment
IMPORTANT NOTE: Improper tank precharge pressure will impact system water production. The tank precharge pressure must be
adjusted at start-up. Tank precharge pressure must be then be adjusted annually.
IMPORTANT NOTE: The tank is empty as supplied. If measuring and adjusting the tank pressure after start-up, be sure the tank is empty.
1. If you have booster pump, unplug. Close the inlet water shut-off valve and the outlet (product) water shut-off valve.
2. Open the tank shut-off valve and drain the tank. If conducting the re-adjustment after start-up, the tank may be emptied through either the
tank sample valve or the sample valve on the outlet line. Leave one or both of these open during the measurement and adjustment.
3. Locate the Schrader Air Valve on the tank. Using a standard bicycle or automobile pressure gauge that is capable of reading pressure
accurately from 0-40 psi (0-276 kPa), connect the air pressure gauge to the Schrader Air Valve and read the tank’s air pressure.
4. The pressure as shipped is about 26 psi (179 kPa). The air pressure for proper system operation should be 28-32 psi (193-221 kPa). If the
air pressure is below 28 psi (193 kPa) or above 32 psi (221 kPa), complete the following steps.
• Using a standard bicycle pump, add or release air pressure in the tank.
• Repeat until the pressure is 28-32 psi (193-221 kPa).
5. Close the tank sample valve and the sample valve on the outlet line. Open inlet and outlet valves. If you have booster pump, plug
in. Allow sufficient time for the tank to refill before operating equipment. Approximate tank fill times are given in the table on next
page.
