WARNING
Read warnings, pages
• 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
•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.
Installation
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 FIG. 2 shows a heat loss curve for 3 com- mon types of tubing.
Chart Notes:
•The greater the flow rate, the less the heat loss.
•
•Locate heater close to spray area to minimize heat loss through plumbing.
