The Ecosoft CROSS MAX is a high-capacity, tankless reverse osmosis water filtration system designed to deliver purified drinking water directly to your tap. With an 800 GPD reverse osmosis membrane and a rated flow of up to 2 litres per minute, it provides fast, convenient water purification without the need for a conventional storage tank.

Designed for under-sink installation, CROSS MAX combines a compact housing, integrated booster pump and advanced reverse osmosis filtration. Its four-stage purification process reduces dissolved impurities and mineral content, while the prefiltration cartridge helps protect the membrane from sediment and residual chlorine.

Automatic membrane flushing, electronic filter-life indicators and a leak sensor make CROSS MAX a convenient solution for households looking for high-output drinking water filtration.

How the Ecosoft CROSS MAX Filtration System Works

CROSS MAX uses a four-stage purification process delivered through two replaceable cartridges.

Stage 1 – Sediment Prefiltration

The first filtration stage reduces suspended particles such as sand, rust, silt and other sediment. This helps protect the downstream filtration components.

Stage 2 – Activated Carbon Prefiltration

The prefilter also contains activated carbon to reduce residual chlorine and selected organic compounds that may affect water taste and odour or damage the reverse osmosis membrane.

Stages 1 and 2 are incorporated into the combined CPVCBDFRO prefilter cartridge.

Stage 3 – Reverse Osmosis Membrane

The 800 GPD reverse osmosis membrane is the principal purification stage. It reduces dissolved salts, mineral impurities and other dissolved substances as water passes through its semipermeable membrane.

Stage 4 – Activated Carbon Treatment

The system's final carbon filtration stage helps improve the taste and odour of the purified water. This is incorporated into the membrane cartridge assembly.

The two replaceable cartridges are:

• CPVCBDFRO – combined sediment and carbon prefilter.

• CSVPDRO800 – 800 GPD reverse osmosis membrane cartridge with carbon filtration.

High-Flow Tankless Reverse Osmosis

Traditional domestic reverse osmosis systems generally use a pressurised storage tank to hold purified water before it reaches the drinking water tap.

CROSS MAX takes a different approach. It produces purified water directly when the tap is opened, allowing customers to benefit from a high-flow RO system without allocating cupboard space to a separate storage tank.

Its rated performance includes:

Performance parameter	Specification
RO membrane capacity	800 GPD
Rated direct-flow capacity	120 L/hour
Rated flow rate	2 L/min
Approximate 200 ml glass filling time	6 seconds
Water recovery rate	Up to 67%
Purified-water TDS	Typically 5–15 mg/L under specified conditions
Storage tank	None

Actual output depends on inlet pressure, water temperature, feed-water quality and cartridge condition.

Compact Under-Sink Installation

CROSS MAX is designed to fit beneath a kitchen sink, making it suitable for modern kitchens where storage space is valuable.

Its approximate dimensions are:

304 × 198 × 191 mm (H × W × D)

The system has an integrated pump and requires an electrical connection. It also needs a cold-water feed, a connection to the household drain and a dedicated purified-water tap.

The installation should include a pressure reducer at the inlet, as required by the manufacturer.

Water Quality and Operating Requirements

CROSS MAX is intended for use with suitable cold municipal tap water.

The manufacturer's published feed-water limits include:

Parameter	Maximum / acceptable value
Feed-water pH	6.5–8.5
Total dissolved solids (TDS)	1,500 mg/L
Total hardness	500 mg/L as CaCO₃
Free chlorine	0.5 mg/L
Total iron	0.3 mg/L
Manganese	0.1 mg/L
Feed-water temperature	+5 to +30°C
Inlet pressure	Check current model documentation; published materials vary

A pressure reducer is mandatory. The manufacturer identifies 3.5 bar as the optimal operating pressure in its installation and warranty guidance.

Water outside the manufacturer's quality limits may require additional pre-treatment. The system should not be used to treat microbiologically unsafe water or water of unknown quality without appropriate prior disinfection.

Purified Water Characteristics

The manufacturer's published specifications indicate a typical purified-water TDS range of approximately 5–15 mg/L under specified conditions.

Reverse osmosis reduces dissolved mineral content as part of its purification process. CROSS MAX does not include a mineralisation stage.

If you want purified water with added calcium and magnesium, consider an Ecosoft PURE Balance system instead.

Smart Operation and Automatic Flushing

CROSS MAX includes electronic features designed to simplify everyday operation and maintenance.

Automatic membrane flushing

The system automatically flushes the membrane as part of its operating cycle. Manual flushing can also be initiated using the control panel.

Cartridge replacement reminder

The filter-life indicator tracks the remaining cartridge capacity and alerts the user when replacement is approaching.

Leak detection

The supplied leak sensor helps detect water leakage around the installation.

Continuous-operation protection

The system includes an overtime protection function. If it operates continuously for more than 10 minutes, it automatically stops water supply. The operating mode must be reset in accordance with the manufacturer's instructions.

Replacement Cartridge Schedule

CROSS MAX uses two dedicated replacement cartridges.

Replacement cartridge	Function	Recommended replacement
CPVCBDFRO	Sediment and activated carbon prefilter	Up to 2,000 L or approximately 12 months
CSVPDRO800	800 GPD RO membrane cartridge with carbon filtration	Up to 2,000 L or approximately 12 months

Actual cartridge life depends on incoming water quality, daily water consumption and operating conditions.

The electronic indicator helps monitor remaining filter capacity. After replacing cartridges, the system must be reset and flushed according to the installation manual.
