Check the height of the waterline on AquaVac:
- Ensure that the filter is clean.
- Put the cleaner in the water and observe the height of the waterline on the cleaner. For this purpose,
let it perform several cleaning cycles in order to determine an average height.
- Once the waterline is settled, if the cleaner regularly makes excessive rattling noises, takes air in through
the bottom cover, climbs up the edge of the wall instead of going back the other way, or if it tends to stagnate
in the same zone of the pool, it is probable that AquaVac is climbing too high: install the reducer kit.
Optimum waterline height
Installing the Thrust Restrictor Plate
If your units' average climbing height is incorrect, it can be corrected by installing a Thrust Restrictor Plate.
Install the restrictor plate as show in Figure 2 by placing restrictor plate in the slot and rotate clockwise to
lock in place.
Restrictor insert may be needed if cleaner is still climbing too high.

For the cleaner to operate properly...
The best water temperature for optimum operation of AquaVac lies in the range 10°C to 35°C. However,
AquaVac can be used in water at a different temperature.
Regular cleaning of the filter cartridge after use, every time the cleaner is used, epitomizes performance of
the appliance. If AquaVac is struggling to climb up the walls of the pool, wash the filter and then resume pool
cleaning.
Replace the brushes (12) when they are worn to maintain effective cleaning.
If granulated chemical products are used on a daily basis in the pool, we recommend using a floating or
automatic metering feeder because such a feeder retains the calcium sediment that is sometimes contained
in that type of product.
It is recommended not to use AquaVac before all of the chemical powders are not dissolved because they
could clog the filter.
In a hard-water pool, more frequent cleaning of the filter is advised. Keep the AquaVac packaging for storing
it or transporting it (in case any repairs are necessary).
The motor unit (13) and the power supply box (1) do not contain any parts that are of use to the user. If they
are opened the warranty automatically becomes NULL AND vOID.
