INITIAL STARTING AND PRIMING: -
On a pebbled pool, it is suggested that all loose stones be swept to a point at the bottom of the pool and removed prior to initial filling. This will prevent an abnormal load on the filter cartridge and pump causing damage to either unit.

First, remove the wing nuts, bolts and clamps from the lid. Grip the lid "wings", twisting quarter turn anti clockwise with a light downward pressure until it stops. Lift Lid.

Grip knob on cartridge top and lift out with a slight rocking, twisting motion. Make sure rubber lid gasket is well greased. Leave cartridge out of tank until pump priming procedure is completed. Replace lid, pushing downward, and rotate quarter turn clockwise in one gentle motion until it stops.

It is not necessary that the lid be extremely tight as the rise in internal pressure when the filter is operating causes the lid to tighten. Position ring halves in relation to lid "wings" and push together, making sure underside is engaged. Insert bolts and secure with wing nuts. Open Air Release valve in lid located next to pressure gauge and leave open until pump is primed.

To prime the pump for the first time, remove the pump's hair and lint pot lid, insert a garden hose in the pump hair and lint pot and allow to flow for several minutes to make sure pump line is full. Replace pump lid.

NOTE: If pump does not prime within three minutes, turn off and repeat the priming procedure. Permanent damage can result by running the pump dry (in an unprimed condition) for prolonged periods. Should the pump not prime after repeating the procedure several times, you may have a blocked suction line, requiring correction before continuing the start-up process. Should the pump fail to re-prime when turned on, a leak in the suction piping or a poorly sealed pump hair and lint pot lid is indicated.

When priming of the pump is finished, water will surge from air release valve when the tank is full of water, when this occurs, close off air relief valve. Allow the pump to run a couple of minutes to clear the pipe lines.

Then, switch off pump. Replace the cartridge, making sure bottom outlet on cartridge is in full engagement in the bottom outlet of the filter tank. Do not drop cartridge into tank, locate hole by spinning cartridge when in the tank until the cartridge drops in place. Replace the lid, centring the "spring hold down" in the lid with the centre located in the cartridge handle. Push lid downward, rotating clockwise as previously described, securing lid and clamp rings, making sure clamp rings are in full engagement under tank neck ring. Open air release valve on lid. Now switch on the pump to commence the filtering process. Tighten air valve after all air has been expelled from the tank.

It may require a few days to clear the pool water due to excessive particles found in the water and loose dust during construction (cloudy appearance).

Inspect the pressure gauge periodically for increases in pressure. This is normal the first week of filtering, and it is suggested that the cartridge be removed and cleaned as needed until the water clears up.

Frequency of cleaning the cartridge will depend upon bathing load use and local conditions of airborne debris and weather. A manual air release valve is furnished with the Hydroflo to remove entrapped air within the system. The air must be removed after every cleaning and whenever the pump hair and lint basket is cleaned.
