STAGE 4 - POOL MAINTENANCE & OPERATING GUIDE
STEP BY STEP THROUGH THE EQUIPMENT
Surface Skimmer-
This will be found at the top side of the pool wall just under the top rail, the skimmer draws water
and surface debris off the pool over a floating weir; debris is caught in the skimmer basket with
the water being filtered. The skimmer basket will need to be checked and cleaned of debris
on a regular basis. With the pump switched off; remove the skimmer lid and lift out the
basket.
The water level must be maintained at least half way up the skimmer opening. Be aware
that when the pool is in good use and heated evaporation can account for water loss of
between 2” to 3” per week, even with the summer ‘bubble’ cover in place when the pool is
not in use!
Return Inlet- Found in the wall about 12” underwater. This returns filtered water back to
the pool.
Circulation Pump- A self-priming continuous rated pump with a pre-filter strainer pot draws
the pool water from the skimmer and delivers it to the filter. The strainer pot basket will need
cleaning on a regular basis. To carry this out, ensure the pump is switched off, close the
suction valve in front of the pump and turn the multiport valve to ‘closed’, remove the pump
lid, usually held on with two thumb knobs or a clamp band. Remove the basket and clean
out, replace basket, top strainer pot up with water if required, replace lid ensuring that lid
‘O’ ring is in place and tighten, open valve and return multiport valve handle to ‘filter’ and
switch pump on.
A pump is ‘primed’ when the strainer pot is full of water. If the water level in the pool drops
below the skimmer opening or you take an attached vacuum head out of the water you will
loose prime.
To ‘prime’ the pump. Ensure the pump is switched off, close the suction valve in front of the pump
and turn the multiport valve to ‘closed’, remove the pump lid, fill strainer pot up with water, replace lid ensuring that lid ‘O’
ring is in place and tighten, open valve and return multiport valve handle to ‘filter’ and switch the pump on. The pump
should prime within a few minutes, if not- repeat the above process, if this still fails call your pool supplier.
Filter & 6-Way Multiport Valve- The filter (silica sand unit) is placed by the side of the
circulation pump. The multiport valve will found on top of the filter, easily identified by a black selector
valve ‘handle’.
The sand filter takes soiled water from the pump and under pressure enters the top of the filter, this is
then forced down through the sand, the sand traps debris and fine particles within it, allowing clean
filtered water out of the bottom of the filter back to the pool - see dia.1 below.
The pressure gauge found on the multiport valve records the back pressure on the sand thus,as the sand becomes dirty
the pressure will increase. When the pressure gauge has increased by approximately 20-30% a backwash cycle is required
see dia. 2 below.
REGARDLESS WHETHER YOUR FILTER IS DIRTY OR CLEAN IT IS IMPERATIVE THAT YOU BACKWASH AT LEAST
ONCE A WEEK TO REMOVE CHEMICAL RESIDUE.
