PASTEURISATION

If a pasteurisation cycle is to be used at a temperature raised above the standard set-point this can be achieved in one of three ways,
the method chosen will depend on the frequency and monitoring required. Contact Lochinvar Technical Support for further guidance.
1 Use the BMS 0-10v output to raise the temperature, for example 8v could be set at 60°C while 10v will set the water heater
temperature to 70°C.
2 Manually raise the temperature via the SMART SYSTEM CONTROL see Section 17.5.1 Use the DHW Night set back
facility to automatically raise the temperature either daily or weekly.
17.8

PASTEURISATION USING THE NIGHT SET BACK FACILITY

The procedure below assumes a DHW set point of 60°C is required with a pasteurisation temperature of 70°C required.
1 Set the DHW tank setpoint to 70°C see Section 21.4.1
2 Set the Night set back offset to 10°C see Section 21.1.5
3 Set the Night set back times for each day to start at 01.00AM and end at 11.55PM see Section 21.1.6
This will set the water heater to operate each day between 1AM and 11.55 PM at 60°C and then the temperature will raise to 70°C
between 12AM and 1AM.
Using this function the EcoKnight™ SMART DISPLAY will show the heater is in Night set back mode
during normal working hours.

INSTALLATION NOISE

If care has been taken to follow the manufacturer's instructions, there should be no discernible noise from the equipment. The allied
pump motor may have a level of sound that could lead to consideration for acoustic insulation, but care must be taken not to impede
ventilation or airflow to the pump motor.

18.0 LPG FUEL

Note! It is strongly recommended that, on LPG installations, gas detection equipment is
fitted. This equipment should be positioned near the appliance and at low level. It is also
important that the space housing the appliance is adequately ventilated at high and low
level. This appliance must not be located below ground e.g. in a cellar.
