We also recommend that all tanks are used with a RCD power break device such as the unit featured on page 55. This tank contains two spray wash bars at the top, driven from a single mains water inlet, between which the developed, etched stripped or tinned board can be suspended to be rinsed. A bottom tube permits used water to be run off to waste. Width 180mm, Depth 525mm, Height 380mm. This, the most popular of single tanks, includes the heater and thermostat sensor as described above and has a pump fitted which forces air through two bubble bars to provide efficient and even etching.
Illuminated switches control mains power and the pump whilst a neon indicates heater operation.
The switches and neon have splash proof covers. The temperature is set by adjusting the variable thermostat control knob. The tank is supplied with a syphon, IEC socket and 2 metres mains lead with moulded 13amp plug. Width 180mm, Depth 525mm, Height 380mm. Neons indicate when the mains heater is operative.
