Page 17: Maintenance
There are no user serviceable components in the 2230/4430 Temperature sensing Valves. The setpoint is preset by AMOT and it is recommended that the unit is returned to AMOT if the setpoint requires adjustment. To test the setpoint, refer to Section 5.2. - Page 18 Allow the Valve to cool and ensure that it closes when the temperature falls below the setpoint. If the “VENT” port leaks in the ‘cold’ condition or the setpoint requires adjustment, return to AMOT at the address shown on the back cover of this manual. Rev 2 – May 06...
