Daily Shutdown
1. Set control switch to “Pump” pump running, burner off .
2. Allow the fl uid to circulate for approximately 20-30
minutes and then set the control switch to the “Off ”
position.
3. When using fl uid cooled pump, continue to circulate
cooling water to pumps for 30 minutes after stopping
circulation.
4. Open power supply switches.
5. Units switched off by an automatic time switch should
have an extra relay fi tted to allow 20-30 minutes of fl uid
circulation after stoppage in order to prevent localized
over heating of fl uid.
6. Close fuel valves if required. Closing of system valves
is not generally necessary unless maintenance of
components requires a partial draining of the system.
7. Because of the high temperatures usually applied, leaks
are not expected to occur when cool down is achieved,
provided pipework is free to contract naturally when
cold.
Before Leaving the Installation
1. Check all controls to insure they are operating properly.
Cycle the heater several times by raising and lowering
operating temperature on the thermostat.
2. Make sure the installation complies with all applicable
codes.
