IMPORTANT SAFETY INSTRUCTIONS
READ AND SAVE THESE INSTRUCTIONS FOR
FUTURE REFERENCE.
Means for all pole disconnection must be incorporated in the
xed wiring in accordance with the wiring rules.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualied persons in
order to avoid a hazard.
The following specications for the cooler water supply are
required:
Min Water Pressure: 15psi (100kPa)
Max Water Pressure: 115psi (800kPa)
New hose sets supplied with the appliance are to be used and
old hose-sets should not be re-used.
WARNINGS
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
1.Installation work and electrical wiring must be done by
qualied person(s) in accordance with all applicable codes
and standards, including re-rated construction.
2. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
3. Ducted fans must always be vented to the outdoors.
4.Do not use this fan with any solid-state speed control device.
EMPLOYER AND EMPLOYEE RESPONSIBILITIES
The installation and maintenance of evaporative coolers at
height has the potential to create Occupational Health and
Safety issues for those involved. Installers are advised to
ensure they are familiar with the relevant State and Federal
legislation, such as Acts, Regulations, approved Codes of
Practice and National Standards, which o󰀨er practical guidance
on these health and safety issues. Compliance with these
regulations will require appropriate work practices, equipment,
training and qualications of workers.
Seeley International provides the following information as a
guide to contractors and employees to assist in minimising risk
whilst working at height.
INSTALLER AND MAINTENANCE CONTRACTORS -
RISK ASSESSMENT
A risk assessment of all hazardous tasks is required under
legislation. A risk assessment is an essential element that
should be conducted before the commencement of work, to
identify and eliminate the risk of falls or to minimise these risks
by implementing control measures. There is no need for this to
be a complicated process, it just is a matter of looking at the job
to be done and considering what action(s) are necessary so the
person doing the job does not injure themselves.
This should be considered in terms of:
• What are the chances of an incident happening?
• What could the possible consequence be?
• What can you do to reduce, or better still, completely get rid of
the risk?
SOME POINTS TO CONSIDER
• What is the best and safest access to the roof and working
areas?
• If a worker is alone, who knows they are there and if they get
into di󰀩culty, how can they summon help? (Call someone on
the ground? Mobile phone? Etc.)
• What condition is the roof in? Should the trusses, underside
or surface be checked?
• Does the worker have appropriate foot wear? (Flat sole jogger
type is advisable.)
• Are all power cables / extension leads safe and appropriately
rated?
• Are all ladders, tools and equipment suitable in good
condition?
• Where ladders are to be used, is there a rm, stable base for
them to stand on? Can they be tied or secured in some way
at the top? Is the top of the ladder clear of electricity supply
cables?
• Is there a roof anchor to attach a harness and lanyard to? If
so, instruction should be issued for the use of an approved
harness or only suitably trained people used.
• Are all tools and materials being used, prevented from
slipping and falling onto a person at ground level? Is the area
below the work area suitably protected to prevent persons
walking in this area?
• Does the work schedule take into account weather conditions,
allowing for work to be suspended in high winds, thunder
storms/lightning or other types of weather giving wet, slippery
surfaces?
• Is there an on-going safety check system of harnesses,
ropes, ladders and access/lifting equipment and where they
exist on roofs, anchor points before the commencement of
work?
• Is there a system which prevents employees from working
on roofs if they are unwell or under the inuence of drugs or
alcohol?
• Are there any special conditions to consider i.e. excessive
roof pitch, limited ground area, fragile roof, electrical power
lines?
OTHER IMPORTANT REQUIREMENTS
• Never force parts to t because all parts are designed to t
together easily without undue force.
• Never drill holes in the tank (reservoir) of the cooler.
• Check the proposed cooler location, to ensure that it is
structurally capable of supporting the weight of the cooler, or
provide an adequate alternate load bearing structure.
Ensure the installation complies with all local and national
regulations with regards to electrical, plumbing and bushre/
wildre construction requirements.
