6.1 Assembly
CAUTION: JBL PROTEMP e300 and e500 are in-line heaters to be installed in the water
outlet hose (pressure side) of an external filter or circulating pump outside the aquar-
ium. Never immerse them in water! This unit contains a glass heating element. Please
handle with the necessary caution.
1 Switch off the external filter and empty the outlet hose. Sever the outlet hose so that
there is enough hose length to position the flow heater as vertically or slightly in-
clined as possible. (Fig. A).
2 Select the hose connections that match the hose of your filter and screw them to
both ends of the heater. The connections for hose 12/16 are already installed. Slide
the severed hose ends onto the connections as far as they will go. Turn the lock nuts
counterclockwise until the hose is firmly seated. Pay attention to the flow direction
marked by arrows on the heater housing. Attach the heater to the suspension loop
provided for this purpose in as vertical a position as possible with the flow direction
pointing upwards (Fig. B).
6.2 Electrical connection
1 Put the external filter back into operation and ensure that all air escapes from the
heater. Trapped air bubbles can cause a safety shutdown of the heater.
2 Make sure that the mains voltage matches the voltage indicated on the heater name-
plate. Then connect the heater to the mains.
