INSTALLATION INSTRUCTIONS

The thermostat must be attached to the face of the heater as noted. Pentair DAHHL

finned heaters are equipped with slotted mounting rails in the fins. Slightly loosen the

mounting bolt included in the thermostat.

Insert the head of the bolt into one of the slotted mounting rails of the finned profile.

The PTFE spacer must remain outside, as this provides the right gap from the

thermostat to the surface of the heater fins. Carefully tighten the bolt by turning the

thermostat. DO NOT OVERTIGHTEN.

The thermostat is equipped with a ground terminal. Use a cable gland or a ½ NPT

conduit depending on the application.

Be careful not to bend or exert any load on the connection cable during unpacking and

transport.

Before entering the customer-supplied Ex junction box, the connection cable must be

firmly installed and mechanically protected observing the permissible bending radius of

5 times the outside cable diameter.

If the connection is made in a hazardous area, the connection cable must be connected

in a housing that meets the requirements of one of the types of ignition protection

mentioned in EN 50014 Section 1.2.

When determining the operating temperature, the maximum permissible ambient

temperature, self-heating and, possibly, heat transfer (medium) must be considered.

In dust hazardous areas, the applicable requirements of the EN 60079-14 have to be

observed.

CAUTION! Remove the RED protection cap only for ½ NPT conduit installation. Never

remove the adapter. See Figure 3 on page 6

The components must only be connected and secured by certified technical personnel

in accordance with the label specifications rated voltage and rated current. Circuit

breakers suitable for up to 16 A can be used for short circuit and line protection.

A ground terminal is provided for the purpose of ensuring potential equalization; see

Figure 1 on page 5. The terminal is marked as such.
