Servicing the 

Pool Pilot  

Cell

The

 Pool Pilot  

 

Cell may require removal for periodic visual inspections, or for servicing when debris or calcium mineral deposits develop. The need to inspect and service the cell 

i

indicated by the following display messages:  “Check System” light, and the message, “Check/Clean Cell”, or ”Purifier Off - C

able 

Flow”.

The 

Pool Pilot  

Cell is installed with Unions on each end to allow quick and easy installation and removal.

9.

The DIG-220 should detect a low water flow at the Tri-

s

ensor, and activate the red Check System LE D.

The DIG-220 will also display the message “Purifier Off! Check Flow.”

1.

Turn off circulator pump.

2.

Slightly loosen the union nut just below the cell on the side of the manifold that does not contain the filter

screen.

3.

Completely loosen the manifold union nut that contains the filter screen and pivot the manifold to gain

access to the filter screen.

4.

Remove the screen. Clean the screen if dirty.

5.

If the screen was dirty, then the system may need to be purged to remove excess debris.  Leave the

manifold off and run the pump for a few seconds until clear.

6.

Wrap the strainer screen securely with a small piece of plastic wrap (saran wrap, food wrap or zip lock

bag) as indicated in the diagram, place it back in the union.

7.

Hand tighten the two unions that were loosened.

1.

Turn off pump and shut off all power.

2.

Detach the 

cel

l cable from the 

Pool Pilot  

Cell

3.

Unscrew the unions at both ends of the 

Pool Pilot  

Cell.

4.

Slide the 

Pool Pilot  

Cell out of the Manifold

 

 

 Assembly.

DO NOT operate system with a faulty flow switch

 

The 

following procedure can be used to verify the proper operation of the flow switch, or to flush debris from the 

Bypass

 Valve.

8.

Turn on the pump and the DIG-220. The plastic will stop water flow to the flow switch, which is part

gh

of the Tri-

s

ensor that is located in the upper portion of the manifold. All water will be forced throu

 

the  Bypass  Valve.  This  action  will  normally  flush  out  any  small  bits  of  debris  trapped  in  the 

Byp

a

ss

 

Valve.)

7.

Check the 

T

ri-sensor assembly for any damage to the plastic housing and replace if neede

d.

1.

Disconnect the Tri-

s

ensor cable from the power center. (Place the end of the cable out of the way, where it will stay dry when the Tri-

s

ensor is removed.) 

 

Please note all

 

cautions and warnings!

2.

Remove the two (2) screws retaining the Tri-

s

ensor in the Tee joint of the Manifold.

3.

Note the orientation of the Directional of Flow Tab. The Tri-

s

ensor must be installed in the same orientation when it is reins

t

alled or replaced.

4.

The Tri-

s

ensor can now be pulled out of th

e Tee

. Firmly grip the Tri-S

s

nsor assembly (this is typically done with a large pair of channel lock pliers). Twist the Tri-

s

ensor back-

and-forth while simultaneously pulling the Tri-Sensor straight out of the Tee joint.

„

Do not use any metallic objects to scrape the blade surfaces or you will remove or damage the blade sensor coating.

„

To remove a calcium scale buildup, mix one (1) part Muriatic Acid into four (4) parts water. Mix the solution in a small contai

n

er tall enough to cover the sensor

blades.  

Always add acid to water, never water to acid,  see warnings above.

„

Immerse the salt sensor blades in the solution for up to 15-minutes.  An effervescing action indicates the calcium is being 

d

issolved from the blades.

„

Rinse with fresh water and reinspect. Repeat the acid treatment as necessary until all scale has been eliminated. Use care n

ot to a

llow the pin connection to ge

t

wet.

5.

Inspect the following on the flow switch: Verify the thin metallic paddle is straight and free from erosion; verify the 

long plastic

 post is straight and free of cracks. Do not twist

or bend the paddle or the plastic post. (see fig 30 on page-26 for illustration of Tri-

s

ensor flow paddle.)

6.

Inspect the two salt sensor blades. The blades should not have any mineral deposits (scale) or other debris on them. If the bl

ad

es need to be cleaned, use the following method

:

The flow switch is a critical equipment protection device. When water flow has stopped, to prevent damage to the cell or system, it is important power to the

 To avoid damaging splashes, always add acid to water,

never water to acid. Wear safety glasses and use other appropriate personal

protection equipment.

Failure to heed the following may result in permanent injury or death.

10. If the DIG-220 did not display this warning, then check the Tri-

s

ensor cable connections and inspect  the Tri-

s

ensor as outlined in the previous section. If the warning message

still does not appear, then turn the DIG-220 

   off 

and contact the factory or your local dealer for assistance.

11.

Turn the pump off.

12. Loosen the unions.

13. Remove the plastic wrap and replace the strainer screen. Hand tighten unions.

14. Resume normal operation.
