2 Introduction
2.1 Description
duty machine used for melting and pumping a variety of hot melt
materials. The melt unit consists of a heated melt tank and a motor-
driven, positive displacement gear pump.
This all-electric melt unit accepts granular, pillow, pellet or block
forms of adhesive. The LS Melt Unit is equipped with a flow
control valve for fluid pressure and flow regulation. The melt unit
is available in 10 and 20 lb tank capacities and supports 1 or 2
automatic or manual applicators and hoses.
The tank temperature ranges from ambient temperature to 205 °C
(400 °F), adjustable by a bimetallic tank temperature controller. An
internal melt grid transfers heat efficiently from the tank heaters to
the hot melt material. The melt grid is standard on the 20 lb melt
unit and an optional feature on the 10 lb tank.
Electrical power to the melt unit is controlled by a circuit breaker
located on the front panel. The electrical panel contains a terminal
block to make connections to the power-in supply circuit. See
Section 4.3: Electrical Circuits and Wiring.
