    FOCKE MELER GLUING SOLUTIONS SAFETY GUIDELINES Mechanical components The hot-melt installation, which is installed to this device, requires moving parts that can cause damage. Use the equipment correctly, and do not remove the safety guards while the equipment is in operation; prevent the risk of possible entrapment due to moving mechanical parts.

  • Page 9: Thermal Components

    Safety Information Sheet of the adhesive. Materials Meler systems are designed for use with hot-melt adhesives. They should not be used with any other type of material, and especially not with solvents, which may cause personal injury or damage to internal system components.

  • Page 10: Intended Use

    The hot-melt melters in the Macro Foam series are designed to be used in the following conditions: • Hot-melt adhesive fusion and pumping at temperatures up to 180 °C (356 ºF). Consult with Meler technical service to operate with higher working temperatures. • Use of hot-melt melters with Meler accessories.

  • Page 11: Introduction

    2. INTRODUCTION Description The Meler adhesive automatic feeder ensures a continuous level of adhesive inside the melting tanks, eliminating the task of manually refilling by the user. Each time the tank sensor detects a low adhesive level it sends a signal to the suction system which, from the container adhesive (or directly from the adhesive bag), transferred a load of adhesive to the melting tank.

  • Page 12: Operation Modes

    FOCKE MELER GLUING SOLUTIONS INTRODUCTION The unit can be installed in the range of Meler hot-melt tanks, as well as other units on request. It supplies the unit load (control, filter, sensors and aspiration mouth suction), together with some specific adaptation to the requested unit.

    INSTALLATION MA-5048-ENG ADHESIVE AUTOMATIC FEEDER 3. INSTALLATION Warning: The vacuum feeders are installed in equipment with updated technology with foreseeable risks. Therefore, you should allow only the access to skilled people, with sufficient training and experience in handling, installation or repair of such equipment. Preliminaries The feeder is normally supplied together with the melter unit, with the elements necessary for installation and use.

  • Page 18: Electrical Consumption

    The power associated with this protection is indicated on the nameplate of the feeder. Compressed air To install ‘meler’ vacuum feeder, it is necessary to have a dry, non-lubricated compressed air system with a maximum pressure of 6 bars. The air inlet pipe is installed to 10 mm outer diameter.
