Frequently Asked Questions - Astrapool VICTORIA PLUS SILENT VS Manuel

FREQUENTLY ASKED QUESTIONS

1. Can the suction vacuum heads work at low speed?
The range of suction vacuum heads available is very large, and the flow-pressure needs for each of them vary greatly.
In most cases the vacuum head start-up makes it necessary to balance the skimmers, suction and pool bottom inlets.
According to this, it is very likely that your suction vacuum head could work at low speeds, after adjusting the
aforementioned inlets. However, if this is not possible, you can always configure additional time at high speed for the
use of the suction vacuum head.
2. Could my heating system work at low speed?
Generally yes, as long as your system is flow controlled (with a flow switch). Most heat exchange systems require a
minimum flow of 6 m
/h to work correctly. This minimum flow is guaranteed at low speeds (except when the filter
3
needs a backwash).
When your heat exchange system is controlled by pressure (with a pressure switch), you should take into account that
the installation may not have sufficient pressure when working at low speeds, meaning that the heat exchange system
will only work when the TURBO mode is used.
3. Can my chemical dosing system work at low speed?
In most cases, yes. Most chemical dosing systems require a minimum flow rate of between 3 and 5 m /h in the case
3
of salt electrolysis equipment. This flow rate is guaranteed at low speeds under all conditions.
However, you should check the minimum operating flow rate of your dosing system to ensure that it is lower than when
the unit is working in low speeds.
4. Should I install a specific electrical box to operate the Victoria Plus Silent VS pump?
No. The pump only require a convention voltage supply. A specific control junction box is not necessary for the pump
operation.
5. Is it necessary to change the hydraulic installation and piping to install the Victoria Plus Silent VS pump?
Installing a dual-speed pump does not involve any special dimensioning or any changes to the design of the installation.
When dimensioning, the operating characteristics of the pump at TURBO speed should be taken into account.
6. Should any precautions be taken if I only want to use the ECO low-speed mode?
If you do not wish to use the high speeds at any time, it must be taken into account that the pressure in the filter will
always be lower than that marked as "filter washing needed". In this case, it is recommended that this level is reduced
to that appropriate to the installation, alongside a visual check of the cleanliness of the filter.
Nevertheless, it is recommended that one high speed cycle per day is programmed.
7. Might there be problems with priming the pump?
The self-suction capacity when using the low speed is lower than when using the high speeds. If you suspect that the
pump has become unprimed, programme the high speed cycle at the start-up in order to ensure fast priming of the pump.
8. Could the lighting system be affected by a Victoria Plus Silent pump?
No, the electrical circuits are independent.
