2.1 POWER AND CONTROL
The Habanero’s resistive heating elements are designed to be powered by 100-120 VAC, 50/60
Hz, 3.6 A and have a heating power of 425 W under these conditions. Reducing the voltage
results in a slower heating rate and reduced maximum temperature.
Power is supplied to the furnace via a permanently attached power cord with a standard NEMA
5-15 plug. The power plug must be connected to a power regulating device, such as our PID
heater controller (p. 16), a variable transformer (Variac), or another user supplied controller.
Direct connection to an unregulated power source (such as the wall or a power strip) will result in
overheating and permanent damage to the furnace.
For temperature monitoring, the Habanero is equipped with a type K thermocouple with a miniature
male straight blade connector.
2. BASIC INSTALLATION
2.2 MOUNTING
For adequate ventilation, at least 3” of clearance on each side and 12” above the furnace is
required. It must be placed on or mounted to a non-combustible working surface. We recommend
elevating it at least 3” above the surface to improve air flow.
The base of the Habanero has eight 8-32 tapped holes for mounting legs or posts.
When the furnace’s internal temperature is high, the furnace’s
exterior surface temperature can reach as much as 130°C (266°F).
Do not touch the furnace when it is heating. Do not put anything
on top of the furnace. Remove all combustibles from the furnace
vicinity (i.e., paper). Do not operate in a fully enclosed space.
