Preventive Maintenance Overview
Britannia canopies and their components are designed to be easy to clean providing that cleaning
intervals are not left too long. When too long a period is left between cleans, grease will become
baked-on and require special attention. An enhanced aesthetic appearance will be achieved if the
cleaned surface is finally wiped dry.
No grease filtration is 100% efficient and therefore there will always be a certain amount of grease
carried through the filters and deposited on the internal surfaces of the filter housings, plenums and
ductwork.
The amount of grease carried through any filtration system will depend very much on the type of
cooking and ingredients used. If left unattended, this layer of grease on the non-visible surfaces of
the Refresh Unit creates both hygiene and fire risks.
Regular inspections are recommended and should cover both the internal and external Refresh
Unit surfaces, especially non-visible ones.
We strongly recommend that the end user should carry-out detailed in-house risk assessments for
all aspects of maintaining Refresh Units.
When handling any components of a canopy, it is imperative that operatives wear proper, gripping,
cut-resistant work-gloves for protection against metal edges, as well as the detergents and
cleaning agents used. No matter how well finished a fabrication may be, it is easy to cut soft water-
soaked skin during the cleaning process.
Canopies and their components by their very nature will have a coating of grease and therefore will
be slippery and difficult to handle. Suitable gloves can be obtained easily through most suppliers of
personal protective equipment. Access to filters for removal & replacement will often mean
reaching above head height and as such, suitable access equipment and or safe working
procedures may be required.
The life expectancy and efficiency of each component part of the Refresh Unit, relies upon careful
maintenance of the entire system. If the maintenance of one component is neglected, then it can
have a serious knock-on effect to other parts of the system rendering them useless or creating
permanent damage.
In essence, good maintenance costs time and money and must be budgeted for. However, a lack
of maintenance will inevitably cost many times as much in the longer term; due to repair bills,
replacement parts, operator discomfort and occupational health risks.
A properly controlled and planned maintenance schedule must be implemented immediately in
order that maximum system efficiency is achieved at all times so minimising occupational health
risks to operatives. This will also reduce the likelihood of nuisance odours and fumes occurring.
