1 Section 1 Introduction Aqua-Clear™ Fiberglass Sand Filter Overview The Aqua-Clear™ fiberglass sand filter provides years of dependable, low maintenance operation. Aqua-Clear superior filtration performance delivers a level of dependability and ease of operation and maintenance. AquaClear features a special internal design that keeps the sand bed level, ensuring even water flow, and resulting in the most efficient filtration possible.
2 Section 2 Installation Note: Before installing this product, read and follow all warning and safety notices and instructions starting on page ii. Installing the Aqua-Clear Fiberglass Sand Filter Only a qualified service person should install the Aqua-Clear Fiberglass Sand Filter. This filter is designed and intended for use to filter water. Introduction The following general information describes how to install the Aqua-Clear fiberglass sand filter.
3 The pressure will rise and the flow to the irrigation system will be lowered as the dirt is collected in the filter. Eventually, the filter will become so plugged with dirt that it will be necessary to perform the backwash procedure. It is important to know when to backwash the filter. Backwashing is discussed further under the subsequent sections of this guide. Please note that a filter removes suspended matter and does not sanitize the irrigation water.
4 WARNING — Failure to position the Automatic Air Vent inside of the Closure will allow excessive trapped air to accumulate in the filter. If the Closure is properly closed, trapped air can cause the Closure to separate and could cause severe bodily injury and/or property damage. 7. Pivot the diffuser out of the center of the tank by rotating the diffuser assembly counter clockwise. Fill the tank about half full of water.
5 Construction of the manifold system To construct the manifold system seen here, use only schedule 40 PVC pipe and fittings to construct it. Shown below is an illustration of the manifold setup in filter position. Always support the long runs of PVC pipe to prevent any added stresses on the filter bulkheads and glue joints and use as short of runs of PVC pipe as possible. Minimize the number of fittings and elbows used in the system. This will reduce pressure drop in your system and improve efficiency.
6 Initial Start-up 1. Connect the water source to the filter, but do not connect the filter to the downstream irrigation system until the filter sand has been adequately cleaned. Always backflush the filter immediately upon start up to remove out the small particles that are in the sand. If you start the system without cleaning the sand, the initial flow of these small particles into the irrigation system can cause clogging. WARNING — Wash the pea gravel before it is inserted into the tank. 2.
7 Section 3 Maintenance This section describes how to maintain your Aqua-Clear Fiberglass Sand Filter. Filter Care The filter is a very important part of the system equipment and installation. Proper care and maintenance will add many years of service to the system. Follow these suggestions for long trouble-free operations: 1. To clean the exterior of the filter of dust and dirt, wash with a mild detergent and water then hose off. Do not use solvents. 2.
8 CAUTION — NEVER PUMP WATER WHEN BOTH 3-WAY VALVE HANDLES ARE HORIZONTAL! Backwash Procedure NOTE: The following Backwash instructions only apply for the manifold setup for two filters. For a single filter setup, refer to your valve instruction manual. 1. Turn pump OFF before turning valve handle. 2. Close the outlet of the manifold using a plug or a gate valve in your irritation plumbing (if installed). 3. Turn the left 3-way valve. The valve will only turn in one direction.
9 Section 4 Troubleshooting Use the following troubleshooting information to resolve possible problems with your filter. WARNING — THIS FILTER OPERATES UNDER HIGH PRESSURE When any part of the circulating system, (e.g., closure, pump, filter, valve(s), etc.), is serviced, air can enter the system and become pressurized. Pressurized air can cause the top closure to separate which can result in severe injury, death, or property damage. To avoid this potential hazard, follow these instructions: 1.
10 PROBLEM CAUSE REMEDY Flow to system diminished. 1. Break in line. Repair line and flush the system before restart. 2. Filter needs to be cleaned Backflush filter according to directions 3. Valve is closed Check pressures and valve settings. Sand in irrigation lines 1. Broken under drain lateral. Replace broken or damaged laterals. Sand loss to waste 1. Backwash rate too high. Reduce backwash flow rate. 2. Improper sand size. Change to proper sand. 3. Air strainer is damaged or missing.
