INSTALLATION INSTRUCTIONS AND OWNER’S MANUAL FOR THE PLAY IT SAFE TECHNOLOGIES, LLC AUTOMATIC PUMP SHUT OFF SYSTEM (patent pending) DISCLAIMER The Play-It-Safe Technologies, LLC Model APS120-240 is tested and produced under the ASME A112.19.17-2010 standard for installation in a commercial pool or spa with a single functioning suction outlet. These instructions are for a 240v ac electric pump motor with 120v ac control voltage up to 4hp or 25 full load amp current draw. The APS 120-240 is designed to release body entrapment. It may mitigate evisceration or limb entrapment. It does not prevent hair or mechanical entrapment. It is designed and tested for pools and spas with a single functioning suction outlet. The Automatic pump shutoff system is designed to serve as an integral part of a multi-layered system intended to help protect against potential life-threatening suction and entrapment type accidents in pools and spas. It should be installed with a suction outlet meeting the ASME A112.19.8 standard. If, in the opinion of the installer, an installation requires even a slight modification the factory should be contacted and the proposed modification approved in writing. Installation must be completed by a licensed, competent electrician according to provisions of the National Electrical Code and any applicable local codes or by a factory representative. The warranty becomes effective when the warranty card is returned showing the name of the installer accompanied by a paid invoice to the installer. The APS 120-240 is designed and tested to be operated in normal operating temperatures for pools and spas. It is not to be used in freezing conditions. The pressure sensor operates between 40 and 150 degrees Fahrenheit. Operating pressures are between 5-30 psi. It will operate with all flow rates produced by pumps up to 4 hp. Check valves should not be installed between the sensor and pump or the pump and the suction outlet. UNPACKING INSTRUCTIONS Your APS 120-240 is shipped with two major components, the enclosure containing the prewired electrical components and the pressure sensor with brass “T”. Inside the electrical enclosure you will find the pressure sensor screwed into a brass “T” wrapped in bubble wrap. Remove the pressure sensor and “T” from the enclosure. Separate the sensor from the “T”. INSTALLATION INSTRUCTIONS
When installing, refer to the attached figures 1-4. Before beginning the installation shut off the pool or spa pump and lock out and tag out the service disconnect for the pool or spa. 1. On the discharge side of the pool there should be a filter with a pressure gauge. Unscrew the pressure gauge and replace it with the enclosed T fitting. Screw the existing pressure gauge back into the top fitting of the T. Screw the pressure detector into the side fitting of the T using the 1/8” x ¼” reducing bushing. The existing pressure gauge and the T have ¼” NPT threads. The pressure detector has 1/8” NPT threads. Use at least 2 full turns of Teflon tape on the threads when installing the T, bushing, pressure gauge and pressure detector to prevent leakage. Hand tighten fittings. See Figure 3.

Examine the existing electrical enclosure for the pool timer and/or start-stop switch. There should be a ground wire of at least 12 ga. and a neutral wire from the service. If there is not a neutral wire one needs to be pulled from the service to the existing enclosure. Make sure that the neutral is bonded to the ground at the service. 3. Mount the new enclosure adjacent to the existing enclosure. The new enclosure is a Hoffman HJ1008HWLG fiberglass Nema 3R/4X enclosure with top and bottom mounting tabs. All conduit attachments should be in Sealtite or equivalent. 4. Disconnect the pump electric motor leads from the existing enclosure. They will be run to the LO1 and LO2 terminals in the new enclosure. Using Sealtite or equivalent, connect the existing enclosure to the new enclosure. For simplicity use the knockout on the existing enclosure where the motor leads entered the existing enclosure. Pull the 4 wires (ground, neutral, L1 and L2) from the existing enclosure to the new enclosure through the new conduit. Attach the wires to their respective terminals on the terminal strip in the new enclosure. 5. Using an electrician’s hole saw add a knockout to the new enclosure for the pressure detector leads. Two wires are used, one to the “C” and one to the “NO3” terminal on the pressure detector. In the new enclosure one is attached to PS1 and the other to PS2. There is no polarity. 6. Make a similar knockout for the LO1, LO2 and ground wires to the pump electric motor. Attach the wires respectively to the marked terminals on the terminal strip. Attach the ground wire to the ground bonding screw. The system is now wired and ready for testing. APS 120-240 OPERATION The APS 120-240 is designed to operate automatically in the background. It does not have an “onoff” switch. It operates with the existing pool or spa controls. When the pool is turned on, the two time delay relays are activated. They complete the circuit to the line side of the power relay coil which turns on the power relay controlling the pool pump. The pressure sensor is wired parallel with the second time delay relay. It enters the circuit and controls the neutral wire to the power relay coil after the system pressure exceeds the pressure threshold in the sensor. After 15 seconds, the first time delay relay, which controls the line side of the power relay coil, turns off. A latching circuit is produced which powers the line side of the coil from the L1 terminal of the power relay. After 90 seconds, the second timing relay, which controls the neutral line to the coil of the power relay, times out. The neutral line to the power relay coil is now being controlled by the pressure sensor. If the suction inlet of the pool is blocked the flow and pressure to the pump is reduced. When the pressure drops below the threshold of the pressure sensor, the neutral line to the power relay coil is interrupted and the power relay turns off the pump. Because of the latching circuit the pump will not turn back on, allowing the trapped swimmer to free himself or herself. The system must be turned back on before the pump will turn back on.
NOTE! ANY TIME THE SYSTEM IS STARTING UP THERE IS A 90 SECOND DELAY BEFORE THE DETECTION SYSTEM IS READY. THE POOL OR SPA SHOULD NOT BE USED UNTIL THE 90 SECOND DELAY IS PAST.
INSTALLATION INSTRUCTIONS AND OWNER’S MANUAL FOR THE PLAY IT SAFE TECHNOLOGIES, LLC AUTOMATIC PUMP SHUT OFF SYSTEM (patent pending) PHYSICAL TEST. A PHYSICAL TEST SHOULD BE PERFORMED ON A WEEKLY BASIS. A SHUT OFF VALVE MUST BE INSTALLED WITHIN 2 FEET OF THE PUMP INTAKE TO PERFORM A SIMULATED ENTRAPMENT. AFTER THE 90 SECOND DELAY, CLOSE THE VALVE SIMULATING A BLOCKAGE. THE PUMP MOTOR SHOULD SHUT OFF WITHIN 4.5 SECONDS. IF THE PUMP MOTOR DOES NOT SHUT OFF WITHIN 4.5 SECONDS CALL THE FACTORY AND CONSULT WITH A SERVICE TECHNICIAN. NO COMPONENTS ARE FIELD ADJUSTABLE. ELECTRICAL COMPONENTS MAY BE REPLACED WITH IDENTICAL MODELS BY A COMPETENT ELECTRICIAN IF DEFECTIVE. THE PRESSURE SENSOR MUST BE REPLACED WITH A FACTORY SUPPLIED REPLACEMENT IF DEFECTIVE. These instructions should be retained by operating and service personnel.
