Install the air heater near the applicator, but in an
area outside of the hazardous location. The unit
should be located so that it is not exposed to water,
paints or solvents, and high temperatures. (The
ambient temperature should not exceed 120
°
F.)
INPUT POWER INPUT POWER

Input supply voltage connection should be made
from a fused disconnect. Route the input power
wires through the side of the cabinet. Generally,
conduit should be used for the input power.

CONNECTIONS CONNECTIONS CONNECTIONS CONNECTIONS CONNECTIONS
Use appropriate size piping to connect the air
heater to a filtered inlet source. The air heater
compressed air input is at the bottom of the unit
and is identified as "IN". Connect the heated air
output located at the top of the unit identified as "hot
outlet pipe" to the coating applicator(s) using 1/2-
inch OD, nylon 11/12-inch tubing, with proper
pressure rating.
A secondary sensing air supply must be connected
to the pressure switch [8] through 1/4-inch OD
tube fitting [29].
If the unit is being wired directly to the PLC
electrical connections, the pressure switch must
be by-passed. (Refer to "Figure 1: Installation
Options" for assistance.)
