PHM-SM-500Wireless Water Level Control Device

INSTRUCTIONS & INFORMATION U.S. AND FOREIGN PATENTS PENDING Congratulations on your Smartmiser purchase. To ensure proper installation, please read these instructions completely before installing your Smartmiser. 1.0 Mounting and Connecting the Receiver: While the Receiver unit is weather resistant, it is not waterproof. Therefore, you should choose a flat surface in a weather-protected area to install the Receiver. Depending on obstructions between the units, the Receiver is designed to receive a radio transmission up to 40 feet from the Transmitter. As the most common installation location for the Transmitter is in the pool skimmer, (See Section 3) you will get optimum performance from the Smartmiser if the Receiver is located within 35 feet of your skimmer and is at least 4.5 feet above the ground. Higher placement will improve reception. Remove the cover of the Receiver. Using the at- tachment screws provided, mount the Receiver on to the protected flat surface using the two openings on the top and bottom of the Receiver. Bend the dipole antennae down towards the ground.

Using a portion of the 30 feet of 2 conductor wire provided, attach 2 wires to the connections on the Transformer and attach those 2 wires to the terminals on the Receiver marked 24 VAC as shown in Figure 1. Plug in the Transformer. Press the wires into the wire slots in the Receiver as shown in Figure 1. The LED light on the Receiver will flash in a series of 4 short bursts which means the Receiver will automatically shut off the water to the pool after 2 hours. See Section 5.3 for more details. 2.0 Hooking up the Gate Valve: It is now time to hook up the Receiver to a valve to fill the pool. For this function, you will need to purchase a standard 24-volt sprinkler valve that can be purchased at most plumbing and hardware stores, directly from Poolmiser, or your local Poolmiser distributor. If your pool is already plumbed with water, install the valve per manufacturer’s instructions into the existing water line. Using the wire provided, connect two of the wires to the terminals in the Receiver marked “valve” as shown in Figure 1. Press the 2 wires into the wire slots as shown. Use the wire nuts to attach the wires to the valve. If you need additional wire, make sure to use 18-gauge wire rated for exterior and underground use, which can be purchased from Poolmiser. If water is not plumbed to your pool, you will need to have a water line installed. (See Figure 5) 3.0 Positioning the Transmitter: The Transmitter has two easily identifiable ledges which will help you position the Transmitter in your pool. The top ledge is the approximate high water PAGE 2COPYRIGHT 2000 POOLMISERCOPYRIGHT 2000 POOLMISERPAGE 7 Figure 2 Top Ledge High Water Mark Low Water Mark Bottom Ledge mark and the bottom ledge is the approximate low water mark. (See Figure 2) Depending on the water level of your pool, you will attach the Transmitter either higher or lower in the water between these 2 ledges. If the water level is at or near its low point at time of installation, then the Transmitter should be installed with the bottom ledge slightly out of the water. If the water level is at or near its high point at the time of installation, the Transmitter should be installed with the top ledge slightly below the water. 4. The signal is sent and received butPossibly a problem with the valve. Re- the water does not turn on.check wiring and connections from the Receiver unit to the valve. Check the solenoid on the top of the valve and replace if necessary. 5. Water shuts off before the poolPossible that automatic shut off function is level reaches the high waterset for a smaller pool. Reset the automatic indicator on the Transmitter.shut off function in the Receiver to a longer time interval per Section 5.0. For all other problems, either contact your pool installer or contact Poolmiser directly and speak to one of our technicians. 307 Sixth Street Petaluma, CA 94952 Tel. (707) 763-7613 Fax (707) 763-0353 8.0 FCC Information: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not in- stalled and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ∑Reorient or relocate the receiving antenna. ∑Increase the separation between the equipment and receiver. ∑Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio technician for help.

Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Gentlemen: This letter is to comply with Section 0.457(d)(2) pertaining to confidential material. Cazden Enterprises, LLC would like the following documents regarding this submission for FCC ID: PHM-SM-500 to be kept confidential. 1.

Page 1 of 1 of Masterwork Electronics Schematics titled: Smart Miser (Transmitter Part) 3. Pages 2 of 2 of “Description of Smartmiser Transmitter RF Circuit”. The above material contains trade secrets or technical data, which would customarily be guarded from competitors. We do not want these documents to be accessible to the general public.

April 9, 2001 Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Re:Cazden Enterprises, LLC FCC ID: PHM-SM-500 Dear Sir or Madam: We are manufacturers of a water-leveling device which utilizes a radio transmission regulated under Part 15 of FCC Regulations. As part of the submittal of our application, we request an exemption from Part 15.19(a)(3) with regard to the labeling requirements on the transmitter device. We request authority to include the mandatory language in the instructions instead of placing the same information on a label and affixing that label to the transmitter. We make this request pursuant to Section 15.19(a)(5) on the following grounds: 1. The transmitter device is partially submerged in chlorinated water. Therefore, the only place to affix a label which would include the mandatory language would be on top of the device. The top of the device is too small to include all of the mandatory language in a readable form. 2. While there are larger flat surfaces on the portion of the transmitter which are submerged, we are concerned that we will not be able to find a label which will stay affixed under continuously saturated conditions with chlorinated water. 3. Because the plastic component is made on an injected plastic mold, it is not possible to engrave the mandatory language into the sides of the mold itself as that would preclude the plastic parts from being ejected properly. Re: Cazden Enterprises, LLC April 9, 2001 Page 2 We would propose to have engraved and/or labeled on the top of the transmitter the following information: Manufacturer: Cazden Enterprises, LLC The Smartmiser Model No. SM-500 FCC ID: PHM-SM-500 We will then include the required FCC language in our instructions under a separate section clearly marked FCC Information. A copy of our instructions is enclosed herewith for your review. We believe that good cause exists to allow us an exemption under Section 15.19(a)(3) based on the physical constraints of labeling the transmitter in any other way. Sincerely, ROBERT P. OLIKER RPO/cas
