Maintenance
ALL work MUST be carried out by technically trained competent personnel.
General Maintenance
The maintenance schedule indicates the time period between maintenance operations. Access to the various
components is via the doors to the front and panels to the side of the unit.
Coil Bleed/Drain
The chilled water coil headers have air bleed and drain valves fitted at the top and bottom of the headers respectively.
Side access for filter maintenance is required for the SO09 and SO12 single slab coil case sizes as well as all A-frame
variants. The air bleed for the coil headers can also be accessed from the sides of the casework. For all other single
slab coil variants the air bleed for the coil headers can be accessed from the sides of the casework if access is possible
or from the front of the unit.
Flood Detection Rope Sensor
If a leak has been detected by the rope sensor, check that all retaining clips are still secure and replace any that have
come loose with a plastic retaining clip with adhesive backing of an equal specification. Ensure the rope sensor has
been wiped dry before resetting.
Working At Height Considerations
The installation of some units may require working at height. A risk assessment should be completed before carrying
out any installation or maintenance work to assess the risks involved. Working at height should be avoided wherever
reasonably practicable and, when it is required, should always utilise either an existing place of work that is safe or
the right type of equipment to carry out the task. The height from which work is carried out should always be kept to a
minimum and all necessary steps should be taken to minimise the risk and consequences of a fall.
Always follow local working from height practices and regulations.
Filters
It is good practice to check filters at each maintenance visit. Unit filter condition is monitored via the microprocessor.
The operational time is indicated along with the operational setpoint. This can be obtained through the maintenance sub
menu of the controller.
No Filter Option
The unit application shall ensure a pre conditioned, filtered supply of air to the data hall to allow the unit to operate
efficiently and prevent contaminants from damaging the unit or data hall equipment. No filtration increases unit
efficiency and cooling performance; with this option selected it is the responsibility of the customer to maintain a clean
environment.
Filter Access
On single slab coil units, for the SO09 & SO12 case sizes, adequate access must be provided from the side to allow
filter maintenance and from the front on the remaining case sizes. For A-frame coil units, adequate access must be
provided from the front and side to allow filter maintenance.
On A-frame units the filter frames are fastened together with a metal clip. When replacing filters, the metal clip must
be fastened between filter frames to allow all filters to be removed from the side of the unit. The supplied filter panel
fastening clips must be correctly fitted when installing filter panels to ensure each filter is connected to the adjacent filter.
This is critical for filter removal from the side of the unit.
The equipment contains live electrical and moving parts, ISOLATE remotely prior to maintenance
or repair work. Ensure electrical lock-off procedures are carried out.
