II. Installation
A. Setup
Unpack and check the system components for damaged or miss-
ing parts. Make sure that the bypass valve and plumbing yoke are
properly connected to each other and to the control valve with the
mounting clips. Make certain that the drain line flow control fitting
is installed properly on the drain port of the control valve. Systems
that are 13" in diameter and larger are not loaded with media. These
systems must be loaded with media before placing into service. To
load a system follow the below steps.
1. Cap the top open end of the distributor tube with tape and plas-
tic sheeting to keep foreign debris from entering the distributor
tube. This cap must be secure and not come off during media
loading.
2. Place the distributor tube, screen end down, into the mineral
tank and center it in the bottom. The top of the distributor tube
should be flush with the top of the tank.
3. Make sure the plastic and tape cap is secure to the top of the
distributor tube, place a funnel on the top of the tank and load
first the gravel then the Micro Z ® media into the tank. The cap
must not come off of the distributor tube during the loading of
the media.
4. Remove the plastic cap from the distributor tube. DO NOT PULL
UP ON THE DISTRIBUTOR TUBE when removing the cap. The
distributor tube top must remain flush with the top of the tank.
5. Clean any media from the threads and top of the mineral tank
and install the deflector disk. See D. Deflector Installation section
for more details.
6. Lubricate the O-rings on the bottom of the control valve (dis-
tributor pilot O-ring and top of tank O-ring). Use non-petroleum
based silicone lubricant only.
7. Place the control valve on top of the tank. When doing this step,
seat the top of the distributor tube inside the centered O-ring
sealed port on the bottom of the valve first then press the valve
down until the tank threads come in contact with the valve
threads. This ensures that the distributor tube is properly seated
into the bottom of the control valve. Thread the valve on to the
tank clockwise. Be careful not to cross thread the valve or over
tighten it. A hand tight snug fit is appropriate for the control valve
torque. A wrench is not necessary. Do not use thread sealant or
PTFE tape on the threads.
8. The system is now ready for installation.
B. Installation Overview
Install the system after the supply lines to the outside faucets. This
system should be installed before a water softener or any taste/odor
cartridges, if applicable.
Ensure the inlet check valve item #5 is connected as shown in
Figure 2 to the inlet side of the 2510 AIO valve. The drain should be
installed in accordance with plumbing codes. Due to the release of
air during regeneration, the drain line should be anchored throughout
the run, secured at the end of the drain line, and properly vented.
The drain line should be sized for the backwash rate listed under
Drain Requirements taking into account friction loss.

D. Deflector Installation
Put a thin layer of silicone lubricant around inside diameter of the
deflector #7. Slowly slide the deflector over the distributor tube down
about 1". When threading the AIO valve to the tank, the bottom of
the threads will slide the deflector down. As shown in Figure 3.
