g b r
Dear Customer,
Thank you for choosing this Atlas Filtri product, made in Italy. Carefully read the in-
formation in this manual before installing the filter. Failure to observe the indicated
instruction null and voids all warrantees. Keep this manual, containing the warranty
conditions, and proof of purchase.
INTRODUCTION
HYDRA RAINMASTER was designed to filter and treat rain water collected in accumulation tanks and
thus used for various domestic, civil and industrial uses.
Use HYDRA RAINMASTER to filter water of all impurities and remove all odours and colours that can
reduce rain water quality and prevent its convenient and satisfying use. Rain water treated with Hydra
Rainmaster must only be used for technical, non-drinking purposes.
HYDRA RAINMASTER is a valid filtering and treatment system for all cases that require filtering and
treatment to obtain clear, odourless and tasteless water, free of pesticides, insecticides and organic
chloride compounds in general.
WARNING
HYDRA RAINMASTER is not a purifier: do not use to filter water intended for drinking if inlet water
quality is not guaranteed for this use or if its origin and quality are unknown.
The HYDRA RAINMASTER range is made up of registered and patented double filters (DUO models)
and triple filters (TRIO models). All filters come with an exclusive self-cleaning pre-filter and active
carbon cartridge for final water treatment. Active carbon cartridges can be carbon block type (CB-EC)
to provide improved flow capacity, or granular carbon type (LA) to provide improved treatment perfor-
mance. HYDRA RAINMASTER TRIO triple filters also come with a fine post-filtration cartridge (FA) up-
stream from the active carbon cartridge to guarantee improved efficiency.

GENERAL REQUIREMENTS

Observe the use limits indicated on the filter label.
If pressure exceeds use limits, protect with a pressure reducer.
Install an "anti-water hammer" system to protect the filter.
Keep away from light sources.
Keep away from excessive heat and cold (min. 4°C, max 45°C).
Only use original Atlas Filtri cartridges. The use of non-original cartridges null and voids the warranty.

TECHNICAL SPECIFICATIONS

HYDRA RAINMASTER filters have been designed and constructed with innovative technical solutions
concerning self-cleaning pre-filter cartridge cleaning system efficiency by washing in counter-current
to remove more substances deposited on the cartridge surface.
The self-cleaning filter has a nominal filtration of 90 micron in the RAH version with stainless steel net
cartridges and RLH version with plastic net cartridge, or 50 micron nominal filtration in the RSH ver-
sions with pleated plastic mesh cartridges.
When the filtering element is clogged, it is simply cleaned by opening the valve on the bottom of the
cup (see figure 1).
This operations generates a depression in the filter that pushes the cartridge down, automatically re-
versing water flow from the inside (in counter-current) out of the cartridge (see figure 2).
This water flow in counter-current carries particles and substances deposited on the cartridge to the
drain. Closing the valve after a couple of seconds returns pressure distribution to its initial conditions
and the internal spring returns the cartridge to its service position (se figure 3).
The HYDRA RAINMASTER filter features a drain funnel, which is a device designed to protect potable
water in water installations against pollution, to prevent pollution by backflow, in accordance with Eu-
ropean standard UNI EN 1717 of November 2002. This device prevents backflow by making all ele-
ments downstream from the solenoid drain valve vent to atmosphere (protection unit symbol: DC).
WARNING: the above described operating modes and cleaning in counter-current
occur in excellent conditions with minimum 1.8 BAR supply pressure. Make sure
supply pressure is not under this value, installing a pressure gauge upstream from
the hydraulic system.

INSTALLATION

CONIC
Before installing the filter it is recommended to install a by-pass and cut-off valve,
keeping both the filter inlet and outlet closed.
Mount the filter on the wall using the support with screws (standard supply).
Connect the filter inlet and outlet connections (NB: outlet indicated by an arrow on
the head) only to pipes with BSP type connections (cylindrical, GAS type) as indi-
cated in the drawing. Use flexible tubes to connect the filter to the pipes if neces-
sary.
CYLINDRICAL(GAS)
WARNING: only use TEFLON
of sealing material or the warranty shall be null and void.
CONNECTING THE FILTER DISCHARGE TO DRAIN
Connect a rubber tube reinforced with canvas to the drain funnel or hose fitting at
SEALANTS
the base of the filter, secure with a clamp and have it discharge into the drain (see
figures 4A and 4B). The drain point must be lower than the drain funnel or hose fit-
ting. The rubber tube reinforced with canvas must not be more than 2 metres long.
WARNING: avoid bending or pinching the rubber tube: this could generate counter-
pressure against the drain with consequent malfunctions.
PASTE
FIRST USE
Proceed as follows after installation and self-cleaning pre-filter drain connections:
- make sure there are no water leaks by gradually opening water supply to the fil-
CANAPA
- gradually fill the filter to about full and then release air in the filter by opening
TEFLON ® TAPE
ter;
the breather screw on the head of the device, making sure all air is released and
the filter filled with water. Close the breather screw when finished. Let a few litres
of water flow from the filter before use. The filter is now ready for correct use.
