Ideal Pressure Gauge Solar 176730

The Ideal Solar Pressure Gauge (part 176730) is a replacement gauge for Ideal solar thermal equipment. It displays the pressure held in the sealed solar circuit, so the engineer or homeowner can see at a glance whether the loop is holding its charge. Gauges of this type are normally mounted on the solar pump station or manifold, where they are read during commissioning and again at annual service.

• The needle rests at zero or does not move when the circuit is pressurised.
• The reading drifts, sticks or jumps, so the system pressure cannot be trusted.
• The dial face is misted, discoloured or the glass is cracked.
• Fluid weeps from the gauge body or from its threaded connection.
• Corrosion or scale has built up around the stem or bezel.

• Match part number 176730 against the appliance documentation, or cross-check the alternative number 1783120.
• Confirm the model and serial details on the solar thermal unit against the compatibility list below.
• Inspect the sealing washer or connection seal at the gauge port and renew it if it is perished.
• Isolate and depressurise the solar loop before removing the old gauge.
