Operating instructions

Installation and General Maintenance Manual – Viron eVo Pool Pump 18
If using a compatible AstralPool Gas Heater you can automatically increase the speed of your Viron eVo pump
to ensure the water pressure switch is activated and the heater obtains enough water flow to operate
correctly.
A RJ12 (6 wire flat cable) specifically wired and obtained from AstralPool will connect your pump and heater.
Refer to Heater Instruction Manual for data cable connection details.
