4. Important
do’s & don’ts
4.1.
Do’s
▪
Be aware and make note of the filter pressure when the sand is clean. Backwash when you see an
increase of 0,3
– 0,6 bar on the pressure gauge.
▪
Backwash long enough to get the job done right. Let the system backwash until the water leaving the
waste line is clear
.
Note that backwashing can remove 200
– 1100 liter of water from your pool so pay
attention
.
▪
P
rotect bottom strainer while replacing or adding sand. Fill the tank with 20
– 30 cm of water and cover
the water chamber to avoid getting sand inside.
▪
Start filter in Backwash mode for approx. 3 minutes and then for about 1 minute in the rinse mode before
initial startup or after adding new sand
.
By doing this you can avoid blowing small particles and impurities
from the new sand into your pool
.
If some debris from the new sand does go into your pool, vacuum it up
with the system in purge mode, otherwise you may keep sending it back to the pool.
4.2.
Don’ts
▪
Do not move the valve handle while the pump is running. It will damage the valve and possibly other
equipment as well.
▪
Do not backwash excessively. Sand filters operate more efficiently during mid-cycle. Some level of
debris in the sand bed helps filtration and makes the filter more effective. Too much backwashing will
reduce efficiency.
▪
Do not vacuum the pool in backwash mode. You can plug up the strain-er at the bottom of the filter
which will result in inefficient operation. Plus, you may have to remove all the sand to get it unclogged.
▪
Do not let the filter system run dry (without water)! The filter pump may never run dry, and damage to
the system caused by running it dry is NOT covered by warranty.
5. Winterizing and storage
1. Unplug the pump from the power source.
2. Clos the shut of valves or block the flow of water at the pool inlet and outlet return ports.
3. Disconnect the filtration system from the pool, drain the tank and hoses. All water MUST be emptied from
the pump as well and it must be placed in a dry place, where it cannot be damaged by the cold. Dry all
parts of the filter pump and hoses, and make sure the interior is completely dry as well. Storing the filter
pump or parts of it while still damp can cause mold and damage the appliance or its components. If this is
the case, the warranty will void. The pump and filter tank cannot endure frost
— frost will damage the
materiel and the warranty is no longer valid.
