7.Clean your filter when pressure reads between 8-10 psi higher than the original starting pressure. Your filter pressure reading will increase as it removes dirt from your pool. However, this buildup of pressure will vary due to different bathing loads, temperature, weather conditions, etc.

a. MY ORIGINAL STARTING PRESSURE IS ___________ psi (pounds per square inch). I SHOULD BACKWASH (CLEAN) THE FILTER AT __________ psi.

8.Check carton for any evidence of damage due to rough handling in shipment. If carton or any filter components are damaged, notify freight carrier immediately.

9.The filter should be mounted on a level concrete slab. Position the filter so that instructions, warnings and the pressure gauge are visible to the operator. It also should be positioned so that the piping connections, control valve and drain port are convenient and accessible for servicing and winterizing.

10.Provide space and lighting for routine maintenance access. Do not mount electrical controls over filter. Install electrical controls (e.g., on/off switches, timers, control systems, etc.) at least five (5) feet from the filter. This will allow you enough room to stand clear of the filter during

system start up.

11.Allow sufficient clearance around the filter to permit visual verification that the clamp is properly installed around the tank flanges, see Figure 1.

12.Allow sufficient space above the filter to remove the filter lid for cleaning and servicing. This distance will vary with the model of filter you are using. See Table 2 for the required vertical clearance.

How to Operate Filter

WARNING —THIS FILTER OPERATES UNDER HIGH PRESSURE.

When any part of the circulating system, e.g., clamp, pump, filter, valve(s), etc. is serviced, air can enter the system and become pressurized. Pressurized air can cause the lid to be blown off which can result in severe injury, death, or property damage. To avoid this potential hazard, follow these instructions.

1.Set rotary valve handle in the filter position.

2.Open air relief valve on top of filter. STAND CLEAR OF THE FILTER.

3.Start pump and wait until a steady jet of water emerges from air relief valve, then close valve.

4.Introduce the required amount of Diatomaceous Earth into filter, see page 4, Table 1.

5.Filter will operate efficiently until pressure gauge indicates time for backwashing.
