1.2 Cylinder unit
* When powered from independent source.
*2 If the water flow rate exceeds maximum, the flow speed will be greater than .5 m/s, which could corrode the pipes.
*3 If the water flow is less than minimum, the flow switch will be activated.
*4 Tested under BS7206 conditions (Primary flow to cylinder coil 80-82 deg C). Conducted by WRc.
*5 Calculated from 24h temperature decay at top of the tank from 65degC (ambient temperature approx. 20degC). Tested by WRc.
*6 Refrigerant of outdoor unit connected to cylinder unit.
*7 The environment must be frost-free.

* When powered from independent source.
*2 If the water flow rate exceeds maximum, the flow speed will be greater than .5 m/s, which could corrode the pipes.
*3 If the water flow is less than minimum, the flow switch will be activated.
*4 Tested under BS7206 conditions (Primary flow to cylinder coil 80-82 deg C). Conducted by WRc.
*5 Calculated from 24h temperature decay at top of the tank from 65degC (ambient temperature approx. 20degC). Tested by WRc.
*6 Refrigerant of outdoor unit connected to cylinder unit.
*7 The environment must be frost-free.
