GRE AR119 Manual De Instalación Y Mantenimiento página 4

• Disconnect the ø25 mm. 4.5 m. length hose from the feedback valve and use the adapter to connect the garden
hose to the filter on the end opposite the tap.
• Disconnect the ø25 mm. 1 m. length hose from the pump discharge and put this end in a drainpipe.
• Open the tap of the garden hose (the water pressure should not be too high, so that the silica sand will not be
ejected) and let the water circulate until you can see that the water which enters the drainpipe is clean. This operation
may take approximately 1 minute, and during this process the connections may leak. This does not mean there is
damage.
• Return the hoses to their original connections and leave the filter idle for a few minutes to prevent the silica sand
from being released into the pool. The filter is ready to begin a new filtration cycle.
7 CLEANING THE BOTTOM AND SURFACE
This pump can not be used with suction bottom cleaners. It must only be used with Ventury bottom cleaners. This filter
is not equipped with a skimmer. Use a leaf collector to clean the surface and a floating chlorine feeder for the chemical
product. See the pool manual for the accessories mentioned.
8 CABLE REPLACEMENT
• Disconnect the unit from the power point.
• Close the suction and discharge valves.
• Disconnect the filter suction hose. Lift the terminal quickly and place it in the pool.
• Disconnect the filter discharge hose. Lift the terminal quickly and place it in the pool.
• Disconnect the ø25 mm. 1 m. length hose from the pump discharge.
• Carefully tilt the monobloc unit and release the pump and its base support (unscrew the four screws with a
screwdriver).
• Disconnect the motor terminals, taking note of their position.
• Remove the cable, replace it, and reassemble the unit by performing the actions described in reverse order.
9 WINTER SEASON - MAINTENANCE WHILE NOT IN USE
During the winter, the water should be drained from the filter and the entire unit (pump, hoses, etc.) For this reason,
after performing a final automatic backwash to clean the silica sand, close the suction valves and discharge valves in
the pool, disconnect the hoses from their filter connections (pump suction, pump discharge, filter cover), and drain the
water which may have remained inside. Wait until all of the water has drained, and make sure that the water pump is
completely dry. Then, store it in a dry place. This operation should also be performed whenever you do not plan to use
the filter for extended periods of time. It is recommendable to take advantage of this opportunity to visually check the
condition of the cable and replace it if necessary. For cable replacement, follow the instructions in the cable
replacement section.
The silica sand need not be removed from the carboy. After the winter season, we will reinstall the filter as though it
were new.
PROBLEM
The motor will not start up.
After connection, there is no flow to the
discharge valve.
The flow rate of the filter is limited.
The filter leaks through the hose terminals.
Water comes out through the upper filter
opening.
If this problem can not be solved, contact the pool manufacturer at the telephone and hours indicated in the instructions.
HOSE D.25 / D.32
CAUSE
No power in the electric line.
Loose terminals on the motor.
The suction valve is closed.
The silica sand is dirty.
The hoses are loose or are not properly
inserted in the terminals.
There is dirt in the coupling on the upper filter
opening.
4
SOLUTION
Check that there is power in the electric line.
Turn on the motor and check the terminals.
Open the valve.
Automatic backwash.
Insert the terminals until they reach the bottom
of the hoses and tighten the clamps.
Remove the silica sand from the opening. Insert
the coupling correctly and retighten.
