WARNING
Read warnings, pages 4-5.
•
Select system components that meet temper-
ature and pressure ratings listed in Technical
Data, page 28. The heater's normal output
range is adjustable from 84-220°F
(29-104°C).
•
Locate heater away from all flammable mate-
rials and where operators will not come in
contact with hot metal surfaces.
•
Insulate and/or label lines and components
exiting heater that may become hot.

Flow Rate
Selecting Tubing
Fluid loses some heat through the tubing or hose
between the heater and spray gun. Locate heater close
to the spray area to minimize heat loss through plumb-
ing.
The chart in F
. 2 shows a heat loss curve for 3 com-
IG
mon types of tubing.
Chart Notes:
•
The greater the flow rate, the less the heat
loss.
•
Foam-insulated steel tubing and high pres-
sure airless paint hose retain heat best. Insu-
lated tubing and hose are more expensive,
but higher costs are commonly offset by lower
operating costs.
•
Locate heater close to spray area to minimize
heat loss through plumbing.
