8.1 Parts List a. Speed Control Gauge Kit
3 1/2' of 1/2" hydraulic hose w/ gauge and fittings Escutcheon plate (3) stainless steel mounting screws
b. Tools Required (supplied by others) (2) Adjustable wrenches (1) Small Phillips head screwdriver 2-1/2" hole saw 1-1/4" hole saw 8.2 Note
The gauge provided is filled with commercial grade glycerin and should not be drained under any circumstance. Do not remove the rubber fill plug. The gauge has been manufactured with an air bubble. That is not a mistake. As the fluid in the system warms up as a result of running the swim current, you will find that the speed of the current (and hence the pressure on the gauge) will diminish somewhat. This is normal for hydraulically operated systems. The actual loss in the current's speed will be no more than 2 to 3 percent.
8.3 Placement Considerations
You can place the speed gauge anywhere on the pool as long as it can attach to the valve assembly. The speed gauge cannot be installed more than 2-1/2’ from the valve assembly due to the length of the 1/2” hose. We have provided pre-cut holes in the front panel of the pool as a suggested place for the controls and gauge. You are not required to use these holes for your installation. If you have selected the Alternate Valve Location Option (Tech Bulletin #3A) and the Retractable Security Cover Option (Tech Bulletin #5), be sure to allow room for the cover to operate. If you did not select the side mounting option for the controls, please call our Customer Service Department at (800) 910-2714 to discuss this option.
8.4 Installation Instructions
1) Once you have selected an appropriate location, lay out the placement of holes according to Figure 1 on page 2. In addition to the hole for the gauge, clearance is needed for the case relief valve (black rubber button) in the side of the gauge. It is very important to drill the holes in the order listed here because the holes overlap. Drilling them in the wrong sequence will leave you no material in which to start the next hole. Also note that the 1-1/4” hole saw will cut into the threads of the top 5/64” hole. This is OK, since little strength is needed to mount the gauge in place. In fact, installing the gauge in a tile coping may be easier by eliminating the mounting screws and simply using silicone adhesive to hold the gauge in place. If this is done, use adhesive sparingly and make sure it does not interfere with the case relief valve. Use hole saws appropriate for the material you are drilling through. For example, tile coping requires diamond-grit hole saws. a. Mark the centers of the gauge, 1-1/4” hole and top 5/64” hole on the coping. b. Drill the top 5/64” hole. Install and remove the screw to cut the threads for the hole now, since doing so will be difficult once the 1-1/4” hole is cut. c. Start the 2-1/2” hole to establish its pilot hole. Do not complete this hole yet! Cut the 1-1/4” hole. d. Finish cutting the 2-1/2” hole. e. Disconnect the gauge from the hose and place the gauge in the hole, aligning it with the top 5/64” hole. Mark the coping for the remaining two 5/64” holes. Remove the gauge and drill the holes.

Figure 1 Swim Gauge Hole Layout 2) If you are placing the gauge in a location other than where we have pre-drilled, drill a 1-1/4" hole in the top flange of the panel in the approximate center of the 2-1/2" hole you just made. 3) Endless Pools® has provided three stainless steel screws for securing the escutcheon plate to the coping. These screws may not be ideal for the coping system that you have selected. You may need to use a more appropriate fastening system when using a tile or rigid coping. Any appropriately sized stainless steel fastener will work. 4) You can now pass the hose up through the hole in the coping and flange and reattach the gauge to the hose after reapplying a small amount of teflon (liquid or tape) to the threads of the gauge. Tighten securely with an adjustable wrench. 5) Place the gauge flush with the coping and secure it using the screws provided or a more appropriate fastener, depending on your installation's coping. 6) Attach the 1/2” hydraulic line from the gauge to the valve assembly on the high pressure side; the right tee of the valve assembly (see attached diagram).
