Dear Mike

Further to your email dated 17th September 2008, please see below for the
additonal information you requested.

The Trust undertakes a 16 week planned preventative maintenance programme
for each of the Air Handling Units. If anything abnormal is identified
during the formal visual inspection such as water ponding in the AHU;
leaking heater or chiller batteries; mould growth; abnormal discoloration
of water in the traps (see table 3), etc. then comprehensive
microbiological tests will be undertaken.

The filters are replaced in accordance with the manufacturer's service
instructions. The actual date for filter replacement is adjusted to fit in
with the 16 week planned maintenance programme (i.e. a manufacturer
recommends 52 week filter replacement so we may choose to replace the
filter at a 48 week interval).

Full details regarding inspection and testing are available in Health
Technical Memorandum 03-01 Specialised Ventilation for Healthcare Premises
Part B: Operational Management and Performance Verification.

Health Technical Memorandum 03-01 supersedes all previous versions of
Health Technical Memorandum 2025 - `Ventilation in healthcare premises'.
