Ideal Meter Window HIU Indirect Unit 177642

The Ideal 177642 is a meter window for the indirect unit of an Ideal heat interface unit (HIU). It sits over the heat meter display so consumption readings can be taken with the casing closed, and it shields the meter face from dust and moisture ingress. Heat interface units are used on communal and district heating schemes to deliver heat and hot water to individual dwellings, and the meter window forms part of the indirect unit assembly. It is supplied as an Ideal Commercial spare.

• The window is cracked, clouded or missing, leaving the meter display unreadable.
• Condensation or moisture is trapped behind the window and obscures the digits.
• Meter readings cannot be taken without opening the unit casing.
• Discolouration or staining on the window makes the display difficult to read.
• The window no longer sits flush in the aperture, allowing dirt onto the meter face.

• Confirm the appliance model and part number 177642 against the unit before ordering.
• Check the alternative number 1783146 if the original number is not listed for your appliance.
• Inspect any seal or gasket around the window aperture for damage and replace it if needed.
