Maintenance.

Routine check (3 monthly intervals)

1.    Check that the pump seal is not leaking.
2.    Check the pump is not seized and develops the correct pressure.
3.    Check that the pump operates without undue noise or vibration.
4.    Check that the motor runs without overheating.

Routine check (6 monthly intervals)

1.    Check the break tank is clean and that the correct water level has been maintained.
2.    Check that all screws are tight on electrical components.
3.    Check that the earth connections are tight and making good contact.
4.    Check that the set points have been maintained by all pressure switches.
5.    Check that the gas pre charge is at the correct pressure, this should be done by isolating the unit from 

System and draining water from the unit by opening the drain cock. The system pressure will now be

discharged  and a tyre gauge can be connected to the pre charge valve to display the vessel pre charge
pressure. Recharge as necessary with Nitrogen or dry air. All other expansion vessels connected to the
system can be checked in the same manner.

Typical MTHW sealed system max. 120°C.
