8 The device is not designed for use by persons of reduced mental, physical or sensory
capacity (including children) or persons lacking experience, unless they are supervised or
instructed in use of the device by a person responsible for their personal safety.
SAFETY INSTRUCTIONS / NOTES:
1 Install water hammer arrester devices to compensate for any overpressure in the domestic
hot water circuit;
2 In the presence of hot water recirculation or if a check valve is fitted at the domestic cold
water inlet, suitable devices must be used to accommodate the expansion of the medium
contained within the system and the heat interface unit;
3 All hydraulic connections must be visually checked during pressurisation. Vibration during
transport may cause the connections to become loose. If a fitting needs to be tightened apply
a proper tightening torque, otherwise the components may be damaged by overtightening.
