1 Weda Poolcleaner AB and Pool Vacuums
Weda Poolcleaner AB has produced pool vacuums for public pools since the mid-1970´s. Today the
products are distributed world wide through own subsidiaries and a distributor network.
The product program consists of fully-automatic or semi-automatic pool vacuums (pool cleaners) for all
kinds of public pools.
Today’s market puts a great demand on the pool vacuums since pools are nowadays designed and built
in various shapes and forms and in a wide variety of sizes and depths. Pool types vary from regular
swimming pools to wave pools, lazy rivers etc.
Since there is a strong connection between chlorination levels in the pool water and the efficiency of the
pool vacuuming it is very important to optimise the pool vacuum for each individual pool. This is not only
based on the pool size but factors like the number of users and environmental issues in and around the
pool play an important role.
Since there is a common demand to decrease the usage of chlorine in pools Weda strives to design
better and more flexible pool vacuums so that we can optimize the vacuum for each pool and meet the
customers’ high demands.
The latest product in the Weda range is the W50. W50 is the smallest fully-automatic and semi-auto-
matic pool vacuum in the Weda range. It is still designed to meet the needs of large public pools with
a large amount of users. And it includes the Weda reliability and more then 30 years experience from
pool-vacuum-design, usage and servicing.
The automatic function is reached by using the latest laser detection system and the most up-to-date
PLC technology available. The W50 uses no moving parts for wall detection.
The fully-automatic function is combined with a remote control option that allows for fast and reliable
movement control all over the pool bottoms.
The W50 is offered in two various basic models: The standard version and the “Super Auto” version with
the possibility to select a number of various cleaning programs. The two models are described in detail
below.
We wish you many good years of reliable pool cleaning with your new W50.

Weda Poollcleaner AB

WEDA W50
Description
The W50 Standard is designed to clean bottoms in rectangular shaped pools.
The user has the option to choose between manual drive with a remote radio control or fully
automatic “one-way” cleaning. “One way” cleaning makes the cleaner clean the bottom in parallel
runs making a U-type turn as it hits the wall. This is a most efficient way to clean most regular pools.
A built-in timer allows for setting of the start time from 0-9 hours and the running time also
up to 9 hours.

4 Installation
The vacuum cleaner must be connected via a Ground Fault Circuit Interruptor (GFCI) or an
Earth Leakage Circuit Breaker (ELCB) or a Recidual Carrent Device (RCD) having a rated residual
operating current not exceeding 30 mA in accordance with Standard EN 60335-2-41 or for the market
valid laws and regulations
Before connecting to power make sure that the wall outlet has:
The correct voltage
The correct fuses
The correct frequency (50 or 60 Hz) and
A GFCI, ELCB or RCD with correct setting (see above)
The power cable (the cable between the control box and the wall outlet) shall be connected so that the
control box cannot be pulled closer to the water than 2 meters (7 ft). This is normally achieved by
cutting the power cable to the desired length before connecting the power plug (see also any local
restrictions since this may vary from location to location).
Read the manual and note the warning signs on the cleaner and the control box.

5.3 Running the vacuum in the pool
First make sure that nobody is in the pool.
If a trolley with the control box is used leave the trolley at a minimum of 2 meters (7 ft)
from the edge of the pool (Check any local regulations that may apply).
Roll out the floating cable (umbilical) and straighten it out as much as possible.
Check the outlet to make sure that the voltage that will be used corresponds to that of the pool vacuum.
Make sure that the outlet is equipped with a GFCI,ELCB or RCD (See above). Contact a local electri-
cian if you have any hesitations about this prior to connecting the power cable!
Fit the filter on the vacuum.
Connect the power cable
Turn the power on and drive the cleaner carefully into the pool. It is important to place the floating cable
into the pool since it is cooled by the pool water.
To avoid over heating do not drive the pool vacuum out of the pool for more than 5 minutes per hour.
5.4 Manual Cleaning
Start by driving the pool vacuum around the walls in the pool and clean thereafter the entire pool bot-
tom at any pattern you may prefer.

One-way
WEDA W50
5.5 Automatic Cleaning
Use the radio remote control to drive the pool vacuum to the selected starting position in the pool along
the right hand shorter wall side. The pool vacuum is set from the factory to work from the right to the left
side of the pool bottom. The turning time is set at the factory and does not normally need to be chan-
ged. If however this is necessary there are two (2) potentiometers inside the controlbox for this purpose.
Please contact Weda or an authorized service centre for assistance set the desired delay time and run-
ning time using the buttons on the control box.Set the program selector in position AUTO.
The W50 is equipped with multiple laser sensors to detect the oncoming wall and initiate a turn and to
detect the side wall at the far end of the pool.
5.6 Recovering the W50 from the pool
Set the program selector in position MANUAL.
Drive the vacuum towards the wall where it will be taken out of the pool.
Put down the radio remote control.
Pull the pool vacuum in the floating cable slowly upwards towards you until you can reach and grab it in
the handle bar. Pull the W50 onto the pool side.
Drive the cleaner to its storage or onto the trolley.
Turn off the power and disconnect the power cable from the outlet.
Remove the filter bag and flush it with clean water. Allow it to dry off before next cleaning if possible.
Flush the cleaner with fresh water (also under the cover)
Look into the suction intake to make sure that no larger particles are caught in the pump

6. Service and Maintenance
6.1. Routine maintenance after use
Check that the drive tracks are free from obstacles like hair, chewing gum, rubber bands
or whatever else that may have got stuck there during cleaning.
Flush the cleaner with fresh water. Make sure to reach also under the cover.
Check the lenses in front of the sensors to make sure that they are clean.
Roll up the floating cable.
Clean the filter bag by turning it inside out. Flush with fresh water.
Allow the filter to dry off completely.
If the cleaning has been performed deeper than 5 meters (15 ft) add grease in the shaft seal
after approximately every 10th hour of cleaning.
6.2 Monthly service and maintenance (after approximately 200 hours)
Greasing of the shaft seal.
For vacuums working no deeper than 5 meters (15 ft) depths the shaft seal should be greased after
every 200 hours of cleaning. Use only food approved white grease Weda Part No WP 740388. Use the
grease gun supplied with the cleaner. Remove the side plate an the left side to reach the nozzle on the
vacuum. Remove the grease nozzle cap, fix the gun to the nozzle and give approx 5 pushes with the
gun to add the correct amount of grease. Avoid overfilling.
Dry off eventual grease that has leaked out and put the nozzle cap back on.
Check:
Drive track tension (see figure)
Brush drive belts (see figure)
General appearance of tracks and belts.
Make sure that there is no damage to the floating cable (umbilical)
6.3 Annual service and maintenance
Must be performed by Weda authorized service personnel only.
For details please refer to the Service Manual for Authorized Weda Service personnel.
