The Reefdoser EVO 4 doser is designed in such a way that it can independently control up to four dosing pumps included in the device.
Feed or additive dispensing can be done in 2 ways , manually or automatically
All pumps can be individually calibrated. Interval control allows adjustment of the on/off cycle length for each pump over a wide period of time, from seconds to days.
Functions
Periodic dispensing of level elements and fertilizers in salt and fresh water aquariums
Controlled calcium and bicarbonate addition for the coral reef aquarium
Exact dosage of Kalkwasser
Automatic feeding with live zooplankton
The external controller can be placed in a position away from the pumps for ease of use and allows for very simple programming.
Technical data
Expandable to eight dosing pumps using reefdoser add 4
Dimensions reefdoser EVO 4: approx. 25 x 13 x 6.4 cm (lxwxh)
Controller dimensions: approx. 14 x 6.5 x 3.6 cm (lxwxh)
It includes 4 m of pipe (can be adjusted individually) to connect the dosing pumps with the containers of liquids to be dosed.
Functioning
Insert the controller into the socket on the right side panel and the power plug into the
back of the Reefdoser.
On the back, there is another connector where the reefdoser add 4 (available as an accessory) can be inserted and controlled.
The pumps (1) are self-priming and must always be positioned according to Fig. 1. This is the only way to avoid total emptying of the container (2). It is recommended to keep the hoses as short as possible (max water height 2 m = 0.2 bar), however, the tube on the suction side must reach the bottom of the container (2). To avoid backflow, be careful that the
dosing hose does not remain in the aquarium water (4). The water level in the container (6) must always be below the end of the dosing tube (5). The water level in the filter / aquarium (3) is not important when these instructions are followed.
Dosing tubes can leak due to wear and tear over the years and then fluids can leak out. Therefore, the dosing pumps, if possible, should be mounted on a drip tray (7), the aquarium or the tank filter. The tubes should be checked regularly for clogging, otherwise leakage could occur due to overpressure.
Protect the dosing unit against splashing water and moisture! Water
fresh, salt water or high humidity as sometimes occurs , for example, inside a
cabinet with filter, could damage the unit.
