Davey POOL AND SPA GAS HEATERS - Manual (Page 18)

Part No: 96131430D 18 Rev: 2
WARNING! Ensure that each valve operated by the actuator is not able to pass through a position that will close supply from the
pump and result in pressurisation of the pool system. Failure to observe this may result in severe damage to the pool system
piping, equipment and or cause personal injury and property damage. Correct installation is the responsibility of the system
installer.
WARNING! Do not attempt to connect 240V equipment to the 24VAC relay.
Note: For models, 131, 127 and 167 a 24VAC relay can be added to enable operation of actuators as previously described. This
component must be installed and connected by a licensed electrician.
