4.0kW, 240V, 3/4" barbs, Low Flow Trombone Heater (26"x6" dual element w/26" 3-wire pigtail cord, & built in TCO).
Common in Jacuzzi & Sundance Spas.
This heater is also used to replace the discontinued heater used by Pacific Spas. Pacific used a heater that was bolted directly to a unique Laing 74359 circulation pump (also discontinued) with a flange style connection. If you are using an older Laing flange style pump (that bolted directly to your heater) and you are replacing your heater, you will also need to purchase an adapter kit. The adapter kit (P/N RPL5-6300K) will convert your old flange style pump to a 3/4" barb.
The adapter kit is not needed if you are replacing with a new 3/4" barbed Laing pump to use with this barbed heater. Simply connect the two with a short piece of 3/4" tubing.
