Page 3: Chapter 1 - Overview
CHAPTER 1 - OVERVIEW he S Tank Monitor represents a massive leap L II forward in level measurement technology for the Recreational Vehicle industry. The SeeLeveL has a combination of features, accuracy, reliability, and diagnostic capability that have never been available before. -
Page 4: Chapter 2 - System Description
CHAPTER 2 - SYSTEM DESCRIPTION he SeeLeveL consists of a display unit that mounts inside the RV, and sender panels that stick to the side of the holding tank. A single two conductor wire is used to connect all the sender panels to the display. - Page 5 If a sender is operating properly and connected to the display with good wiring, then the display will show the level normally. If the wiring is disconnected, shorted, or cut, or if the sender panel is defective, then the display will indicate an error code. The various error codes are shown in the troubleshooting chapter.

CHAPTER 3 - OPERATING INSTRUCTIONS he display is the only system component that is accessed by the user. All user input to the display is done using the three buttons along the bottom of the display. Operation of the display is as follows To read a water or sewer tank level: 1. -
Page 7: Chapter 4 - Display Calibration
CHAPTER 4 - DISPLAY CALIBRATION To program the LED brightness: 1. If the display is to be used inside the coach, the LED brightness should be low. If it is to be used in the service bay area where sunlight can reach it, the LED brightness should be high. 2. - Page 8 4. When the programming mode is entered, the display will show “FrS” if doing the number of senders for the fresh tank or “GrS” if doing the waste tank. When this occurs release both buttons. 5. The display will now show “1SE” (one sender) or “2SE” (two senders), based on what is currently programmed into the display.

Page 9: Chapter 5 - Sender Programming
CHAPTER 5 - SENDER PROGRAMMING To program the 710ES sender for the correct tank: 1. Since the senders are all connected in parallel to save wiring and to simplify installation, the senders must be programmed so they know which tank they are on. The senders can be programmed for either the fresh, grey, or black tank. - Page 10 2. The senders default to single or bottom operation if the programming is not altered. Consequently, if the sender is for single or bottom operation, nothing further needs to be done to it (beyond programming it for the correct tank). 3.

CHAPTER 6 - INSTALLATION GUIDE (NEW OEM INSTALLATIONS ONLY) 1. Please refer to the “Troubleshooting and Installation Tips” section in Chapter 7 for details on avoiding installation issues. 2. The installation consists of mounting the display inside the RV, cutting and fastening the senders to the sides of the holding tanks, connecting wiring, and programming the display. - Page 14 in length, for example, a system with a tank height of 11.75 inches, cut the sender to be 10.5 inches long, this allows 5/8” at each end when the sender is centered vertically on the tank. The JS sender is cut to the nearest 1.0 inch in length. IMPORTANT: Do not cut the 710ES sender shorter than 4-1/2 inches! The sender will not work if it is cut less than 4-1/2 inches.

- Page 18 buildup in the tank. Note that the system “learns” about the characteristics of the tank with use, so the readings may be inaccurate when the tank is empty or almost empty when the system is first tested. Once the tank has been filled at least 1/4 full the system will be properly “taught”...

Page 20: Chapter 7 - Troubleshooting Guide
CHAPTER 7 - TROUBLESHOOTING GUIDE Display trouble codes: If a sender or its wiring is not operating properly, the following codes are shown on the display: 1. If a sender is unresponsive or there is an open circuit in the wiring so that the sender is not connected, the display will indicate an open circuit by showing “OPn”... - Page 21 The diagnostics can be used to check the wiring and the senders: 1. If a short circuit is showing, disconnect the senders one at a time at the sender location. If the short circuit indication goes away when a sender is removed, then that sender is bad. If all the senders are removed but a short circuit still shows, then the wiring may be shorted.
- Page 22 this diagnostic allows the user to confirm the length and to make sure that the auto calibration is working properly. 3. To check the diagnostics, press and hold the button for the tank to be checked, the display will show the level for that tank.
- Page 23 What to do if the system indicates a residual or non-zero water level even though the tank is drained completely: 1. This can be due to a convex tank bottom or a sloped tank bottom. In the case of the convex bottom tank a ring of water may remain after draining.
- Page 24 metal such as steel, aluminum, copper, or brass can affect the sender reading if it is closer than about 2 inches from the face of the sender. If there are metal frame pieces, brackets, straps, pipes, ducts, etc. close to the sender you may have to move the sender away from them.
- Page 25 9. There may be a buildup on the inside walls of black and grey tanks. We get calls occasionally about older coaches that have been in service for a few years in which the black tank will now indicate a level even though it is empty. The likely cause is that the tank has a significant build-up, probably exceeding ¼...
- Page 26 What to do if sender delamination occurs: 1. We have had reports of the senders literally falling off the tanks or showing serious delamination. This is likely caused by a lack of tank surface preparation. Surface prep is very simple, wipe the area to be adhered to with products like Pro Bond, alcohol, or acetone.
- Page 27 2. When fastening the display to the panel, make sure that it is centered in the hole and not resting on one edge. 3. Non-conductive mounting spacers are available to help prevent damaging the display. Contact Garnet for further details. How to avoid damaging the display or pump switch due to excessive current: 1.
