Pay attention to your safety!

1. Safety regulations for paint spraying

The safety precautions provided by the manufacturer of your airless unit are to be observed for safe operation of airless spraying equipment.
The following additional safety regulations must observed when operating the heating hose described in this document:

The heated hose is suitable for processing water-based coating materials. If solvent-based coating materials need to be processed, their flashpoint must be above 55° C.
This value should always be ascertained from the respective material safety data sheet before starting work (available from the material manufacturer/paint supplier). The flash point is the lowest temperature at which vapours develop from the coating material. These vapours are sufficient to produce a flammable mixture with the air surrounding the coating material.

1.2 Explosion protection

Do not use the unit in premises which are covered by the explosion protection regulations. The unit itself is not explosi-on-proof.

1.3 Risk of fire and explosion from sources of ignition during spraying work
There should not be any sources of ignition in the surrounding environment, e.g. open flames, lit cigarettes, sparks, glo-wing wires, hot surfaces, etc.

1.4 Electrostatic charge (spark or flame formation)
Electrostatic charges may develop on the unit due to the flow rate of the coating material in the hose. These charges can result in the formation of sparks or flames. Therefore it is necessary for the airless spraying equipment to be proper-ly earthed at all times (protective earthing conductor on the mains plug).

1.5 Earthing the spray object
The object to be coated must also be earthed in order to prevent an electrostatic charge developing. (As a rule walls are earthed naturally).

1.6 Protective earthing of the heating hose
If an error occurs (defective heating conductor), the protective earthing element of the heating hose ensures the necessary degree of protection against electric shock. This level of protection is established by connecting the mains cable to an earthed socket. It must be ensured that the earthing element of the socket to which the heating hose is con-nected has been properly installed and is functional.

1.7 Heating hose (safety precaution)
An electrostatic charge of the spray gun and the heating hose is dissipated via the hose. Therefore the electrical resi-stance between the connections of the heating hose must be equal to or less than 1 megohm.

1.8 Personal protective equipment
Caution: The heating hose and spray gun become hot during use! Suitable protective gloves must be worn when con-ducting any spraying operation.

1.9 Cleaning the unit
Risk of short circuit as a result of water penetration! Never spray the unit using a pressure washer or steam cleaner.

Cleaning the unit with solvents

When cleaning the unit with solvents the heating element of the heating hose must not be activated,as an explosive air/gas mixture can develop in the hose. The container into which the solvent is pumped must be earthed. The top of the container (bucket) must be completely open due to the risk of explosion (no small opening through which fluid is injected).

1.11 Using the unit on construction sites and in workshops
The mains connection should only be established via a special feed point with a residual current protective device (INF ≤ 30 mA rating).

1.12 Working on or repairing the electrical equipment
No liability shall be assumed for any repair work carried out improperly. Repairs should only be conducted by an author-ised STORCH service centre.

1.13 Working on electrical components
Remove the mains plug from the socket before carrying out any work.

1.14 Max. operating pressure
The permissible operating pressure for the heating hoses is 250 bar. Do not use the heating hoses on paint spraying pumps with a higher operating pressure if they have not been limited to 250 bar.

2. Application overview

2.1 Operational areas
The hot-flow heating hose system has been designed as an accessory for airless paint spraying equipment whose opera-ting pressure does not exceed the nominal pressure of the hoses (250 bar).
The heating hoses are used heat coating materials to 55° C to optimise the atomisation process at the nozzle. In addi-tion to ensuring an optimisedspray pattern this also makes it possible to avoid the additional use of solvents. Further-more, it also reduces material consumption. The heating hose is suitable for both stationary use in workshops or on construction sites.

Caution: The HotFlow 55 7.5 m heating hose system (art. no. 69 15 05) is suitable for STORCH Airless equipment as of date of manufacture 10/2011. If you are using a device supplied by another manufacturer, check whether the device is suitable for 7.5 m hoses.

2.2 Processable coating material:
Water and solvent-based paint (observe the flash point of > 55° C), two- component coatings (observe the pot life), emulsion paint and latex paint. If you wish to use a different coating material please contact us first as it could adver-sely affect the functionality and safety of the unit. Only use coating materials that are suitable for airless units and observe the information provided by the respective manufacturer (technical data sheets): The properties of some coating material are destroyed through excessive heating. Some material can become highly viscous when heated and damage the heating conductor in the hose.

2.2.1 Coating material with sharp-edged aggregates
These aggregates have a high wearing effect on the heating wire located in the hose and also on the hose itself. This adversely affects the service life of the unit.

3. Unit description

The heating hose is heated by an electrical heating conductor located inside the hose. The coating material is heated by electric current flowing through the heating conductor. The material‘s viscosity level is reduced as a result of the hea-ting process. The electronic components in the temperature regulator continuously monitor the preset heating tempera-ture. The heating capacity of the hot-flow heating system is technically limited.

An excessively high volume flow rate (nozzles too large) or very low temperatures of the coating material prior to use can be the reason for the temperature of the coating material not being reached. The ambient temperature also has an influence on the heating capacity of the heating hose.

4. Initial operation

4.1 Connecting the heating hose to the airless unit and spray gun
The HotFlow 55 7.5 m heating hose system (art. no. 69 15 05) is suitable for STORCH Airless equipment as of date of manufacture 10/2011. The heating element on the hose is connected to the airless unit (note: the maximum operating pressure is 250 bar). If the heating hose is mounted on the hose reel, connect it to the airless unit using the connecting hose supplied. The spray gun is to be connected to the other end. Firmly tighten all of the hose connections using the corresponding tool. Attach the nozzle holder and selected nozzle onto the spray gun and screw it firmly in place. Depen-ding on the connection thread, use the enclosed connection adapters on the device and gun sides.

4.2 Connecting the heating element to the mains supply and the heating hose
Before connecting to the mains supply make sure that the mains voltage matches the details on the unit‘s type plate. Unroll the heating element connecting cable before plugging into a 230 V socket.

4.3 Setting the temperature
The temperature is set automatically. The max. temperature is 55° C. The system detects the max. temperature and keeps this autonomously through the thermostat switching on and off. Reaching the max. temperature depends on various factors: the lower the ambient temperature and/er the temperature of the coating material, the longer the heat-up period will be. It can be between around 5 minutes and 20 minutes. If the nozzle you use is too large, the coating material may not reach the desired temperature as the flow speed in the hose is too high. The coating material dwell time in the hose is too short. Use a smaller nozzle and adapt your working speed as needed.

5. General handling of the heating hose

The heating hose is to be handled carefully. Avoid excessive bending or kinking of the hose; the smallest bending radius is around 20 cm. Do not run over the heating hose and protect it from sharp objects and edges. Risk of injury from a leaking hose. Replace damaged hoses immediately. Never repair a defective hose! The heating hose cannot be discon-nected from the heating element / thermostat. Do not open this screw connection. Always unroll heating hoses comple-tely. When working on scaffolding guide the heating hose along the outside of the scaffolding.

6. Interruption of work

During prolonged breaks from work relieve the pressure on the airless unit and unplug the heating hose plug connector from the mains. When using quick-drying or two-component coating material it is essential that the unit is flushed with a suitable cleaning agent within the processing time/open time of the material, otherwise it could result in damage to the unit or require significant expense for cleaning.

7. Cleaning the unit

Cleanliness is the best guarantee for trouble-free operation. Under no circumstances should any material residues be allowed to dry and set in the unit. When the spraying process has been completed flush the unit using a suitable sol-vent in accordance with the manufacturer‘s instructions.

When cleaning with solvents (except water) always switch off the heating element!
The solvent containers (except for water) must be earthed!
Caution!. Do not pump or spray into containers with a small opening (bung hole)!
Refer to the safety regulations. Warm water facilitates the cleaning process for water-soluble coating materials. The heating hose can be switched on for this.

Cleaning the unit from outside

First remove the mains plug from the socket. Risk of short circuit as a result of water penetration! Never spray the unit using a pressure washer or steam cleaner. Wipe the outside of the unit using a cloth soaked in a suitable cleaning agent.
