Moving on from the backpack or pre-pressurised sprayer marks an important step for maintaining structures and plots of land. Carrying a load of several kilos while pumping by hand generates unnecessary fatigue that undermines the consistency of the application. The Pro Sprayer EVO Phoenix 35L addresses this issue by moving the load to the ground on a mobile trolley and entrusting pressurisation to an electric motor. Fitted with a pump capable of reaching 7 bar, this equipment is designed to project fluid solutions over large surfaces or at significant heights.

A successful commissioning allows for no approximation. A misaligned fitting, an O-ring bitten during tightening, or forgetting the basic safety instructions when handling chemical products can damage the equipment or expose the operator to dangerous splashes. This technical document details the assembly steps, the adjustment protocols and the maintenance operations essential to extend the life of the machine.

1. What's in the Pro Sprayer EVO Phoenix 35L pack: inventory and inspection

Open the box on a stable, flat surface. Before starting assembly, carry out a visual inspection of each component to make sure the threads and structures are intact. The EVO Phoenix 35L pack brings together the items needed for immediate commissioning:

• The main high-density polyethylene tank, with a nominal capacity of 35 litres, firmly attached to its frame.
• The rolling components and the trolley's transport axle.
• The reinforced 8-metre hose, designed to withstand high pressures and common chemical formulations.
• The control handle fitted with seals resistant to aggressive agents.
• The 40 cm fibreglass lance, chosen for its light weight and its inertia against corrosive products.
• A set of 4 interchangeable nozzles allowing you to adapt the spray pattern (flat jet, mirror jet, mist jet, straight jet).
• The removable 18V Lithium-ion battery and its mains charging unit.
• The top storage box for small spare accessories.

Absolute safety rule: Mechanical or electrical components must be handled with the power off. Do not insert the battery into its housing before the hydraulic assembly is fully completed.

2. Assembling the Pro Sprayer Phoenix 35L: frame, hose and lance

Assembly does not require heavy tools. A flat spanner or a standard adjustable wrench is enough to secure the threaded connections without damaging the materials.

2.1 Fitting the running gear and the handle

Position the wheel axle at the base of the metal frame. Slide the wheels onto their respective axles, insert the friction washers and lock the assembly by inserting the split pins into the holes provided. Using pliers, firmly bend back the legs of the pins to prevent any axial play during movement. Raise the trolley's transport handle and lock it in the raised position using the locking knobs. The machine must sit level on its wheels and front stand. Fix the hose supports and the lance retaining clip onto the threaded inserts on the tank.

2.2 Connecting the high-pressure hose

The 8-metre hose undergoes repeated pressure cycles. Its tightness depends on how well it is aligned during tightening.

1. Identify the threaded pump outlet located on the lower part of the technical unit.
2. Present the hose's swivel fitting perfectly in line with the thread.
3. Start the first turns by hand. If you feel resistance from the start, unscrew and realign. Forcing it would destroy the brass thread.
4. Once the fitting is hand-tightened all the way, apply a moderate final tightening with the wrench (a quarter turn is enough to compress the seal without shearing it).
5. Connect the other end of the hose to the inlet of the control handle following the same protocol.

2.3 Fitting the lance and selecting the nozzle

Screw the fibreglass lance onto the front outlet of the control handle. First check that the internal O-ring is correctly positioned at the bottom of the female thread.

Then select the nozzle suited to your application. The fixing system at the end of the lance allows for quick locking. Cap the end with the nozzle nut containing the chosen insert and tighten firmly by hand. Unused nozzles find their place in the storage box built into the frame.

3. 18V battery and pressure adjustment: commissioning the Phoenix 35L

Optimal operation of the diaphragm pump depends on a stable power supply and correct priming of the fluid circuit.

3.1 Managing the 18V Lithium-ion battery

Before first use, connect the battery to its mains charger until the battery's charge indicators stabilise. Open the watertight access flap located at the rear of the machine. Insert the battery into its guides until it locks mechanically.

The Lithium-ion battery provides the energy needed for continuous operation of the diaphragm pump under heavy load. Carefully close the protective cover: the ingress of liquid or chemical vapours into the electrical compartment can cause short circuits or oxidise the connectors.

3.2 Priming and adjusting the flow controller

Never run the pump dry for a prolonged period. For the first commissioning, carry out a compliance test with clean water:

1. Pour about 5 litres of clean water into the 35-litre tank.
2. Turn the pressure controller potentiometer to minimum.
3. Switch the main switch to the on position.
4. Point the lance towards a neutral area and squeeze the gun trigger.
5. Gradually increase the pressure using the controller until you obtain a uniform jet, a sign that the air trapped in the pump and the 8 metres of hose has been completely expelled.

Pressure adjustment is done continuously up to the maximum of 7 bar, allowing you to vary the flow rate and the fineness of the droplets according to the nozzle fitted.

4. Use on roofs, facades and green spaces: reach and safety

The Pro Sprayer EVO Phoenix 35L adapts to a variety of configurations, but each environment imposes strict physical and safety constraints.

For the detailed ground-based application technique, see our complete guide to removing roof moss without a ladder.

4.1 Treating structures: roofs and facades

Using the straight jet lets you project fluids to considerable heights, reaching up to 13 metres of range in optimal conditions (no wind, lance tilted at 45°). This is particularly useful for applying moss-removal or water-repellent solutions.

However, the actual range depends directly on air movements. Stop all work if the wind exceeds 15 km/h to avoid drift of the chemical mist towards the operator, neighbouring properties or sensitive vegetation. Using a compatible telescopic pole makes it possible to secure the application on high points without resorting to unstable elevation setups.

[Max range: 13m] --> Sensitive to wind drift

[Pressure: 7 bar] --> Ideal for anti-moss and water-repellent solutions

For a complete methodology on the spraying technique, see our detailed guide to removing roof moss without a ladder.

4.2 Horticultural applications and green spaces

To treat plots, vines or the vegetable garden, favour low to medium pressures combined with the mist or mirror-jet nozzle. This ensures uniform coverage of leaf surfaces without damaging plant tissue through overly violent mechanical impact. The 35-litre capacity offers considerable working autonomy, limiting the tedious refilling and dosing phases.

4.3 Mandatory Personal Protective Equipment (PPE)

The integration of premium Viton-type seals ensures excellent compatibility with common treatment products (facade cleaners, disinfection solutions, horticultural treatments). However, the machine's resistance does not exempt the user from protecting themselves.

Before handling chemical concentrates and filling the tank, you must put on the required PPE: nitrile or neoprene protective gloves, sealed safety goggles with side shields, category 3 protective coveralls and a respirator fitted with suitable filters (A2P3 minimum) against aerosols and organic vapours.

5. Rinsing and cleaning the Pro Sprayer Phoenix after the job

Premature ageing of electric sprayers is almost always linked to the crystallisation of chemical products inside the pump. Moss-removal solutions, whether acidic or alkaline, leave deposits that block the valves or destroy the diaphragms if the circuit is not purged after use.

The Pro Sprayer EVO Phoenix incorporates a dedicated bypass valve for quick rinsing. This device makes it possible to clean the entire hydraulic circuit (pump, hose, handle, lance) without having to drain the product still present in the main 35-litre tank.

Cleaning protocol after each job:

1. Put clean water into a separate external container or bucket.
2. Dip the machine's secondary suction hose into this bucket of clean water.
3. Switch the selection valve (located under the technical cover) from the "Tank" position to the "Rinse" position.
4. Start the pump and spray the clean water towards a retention area or a collection container until the liquid expelled by the nozzle is perfectly clear.
5. Return the valve to its initial position to isolate the main tank.

6. Winterisation and storage of the Phoenix 35L electric sprayer

Frost is the main cause of destruction of pump bodies and brass fittings during the cold season. Residual water, by increasing in volume as it freezes, causes irreversible internal cracks.

To prepare the machine for long-term storage:

• Open the lower drain plug of the 35-litre tank and empty out any remaining fluid.
• Run the pump dry for a maximum of ten seconds or so to expel the standing water trapped in the diaphragm.
• Disconnect the 8-metre hose, coil it without pinching the material and hang it vertically to drain it completely.
• Store the sprayer in an insulated, guaranteed frost-free technical room.

Lithium-ion battery maintenance: Do not leave the battery in the machine or in a room subject to sub-zero temperatures. Remove it and store it in a dry, temperate space (ideally between 15°C and 20°C). To avoid the deep-discharge phenomenon that destroys Lithium chemistry, recharge the battery to around 60-80% before storage, and carry out a maintenance charge every two months during periods of inactivity.

Conclusion & field checklist

Regular maintenance and adherence to mechanical tightening torques determine the longevity of your Pro Sprayer EVO Phoenix 35L. Get into the habit of validating the following key points before each intervention.

• [ ] Storage: The circuit pressure has been released by squeezing the trigger after switching off the pump.
• [ ] Power: The battery is removed from its housing if the machine is not to be reused within the week.

• The Pro Sprayer EVO Phoenix 35L is a trolley-mounted electric sprayer, fitted with a 7 bar pump powered by a removable 18V Lithium-ion battery.
• Initial assembly requires particular attention to the alignment of the brass threaded fittings and the fitting of the pins that retain the frame's wheels.
• The theoretical range of the straight jet can reach 13 metres, but remains dependent on weather conditions. Application is prohibited when the wind exceeds 15 km/h.
• The innovation of the EVO version lies in its bypass valve, allowing the pump and accessories to be rinsed with clean water from an external container without draining the tank.
• Winterisation requires the complete purging of residual water to avoid the pump freezing, as well as storage of the Lithium battery in a temperate room at half charge.

FAQ - Pro Sprayer EVO Phoenix 35L: your frequently asked questions

Which products are prohibited in the Phoenix 35L tank?

Pure solvents, flammable products (petrol, kerosene), highly concentrated acids and mixtures based on undiluted pure chlorine are strictly prohibited. They destroy the internal components (including Viton seals) and create a risk of accident.

How long does it take to recharge the 18V battery?

The supplied fast charger restores the Lithium-ion battery's nominal capacity in about 1h30 to 2 hours, depending on the ambient temperature and the initial level of discharge.

The pump runs but no liquid comes out of the lance, what should I do?

Check that the selection valve is set to "Tank". Unscrew the nozzle at the end of the lance to reduce back-pressure, then briefly push the controller to maximum to expel the air pocket trapped in the circuit.

Can competitor-brand poles be used on this machine?

Compatibility depends solely on the thread of the fittings. The Pro Sprayer EVO uses standard thread pitches. To avoid pressure losses or leaks at 7 bar, the EVO telescopic poles developed specifically for this model remain strongly recommended.

How do I maintain the Viton seals to prevent them from drying out?

The best maintenance is rinsing with clean water after each use. For long-term storage, apply a thin film of silicone grease or neutral petroleum jelly to the accessible O-rings of the lance and handle.
