NB001-04 - Product Change Notification - MCU+, MHPUE, MHPUL, CKC
22nd January 2004
The position of the Fan / Motor assembly is being changed in order to increase the distance between the fan blade and the grille. This follows a recommendation made by an external consultant.
Unit performance is not affected.
With immediate effect all Marstair 22 series MCU+ 15-80, MHPUE / L 15-60 and CKC 20-80 will become 23 series units.
Example, 55022005 ( MCU+40 1ph ) will become 55023005.
Prices remain unchanged and revised price lists with the new part numbers will be issued shortly.
The spare Fan / Motor assembly for the 23 series unit is 55023950S.
List price is the same as the 22 series equivalent £126.
The 22 series Fan/Motor spare, 55021005S, and the 23 series Fan/Motor spare are NOT interchangeable.
Similar changes to MCU+ 90-200 and MHPUE / L 80-180 will be introduced as a running change when material stocks of 22 series have been used.
