SAFETY
4Seeley International Pty Ltd
EMPLOYER AND EMPLOYEE RESPONSIBILITIES
Installer and Maintenance Contractors
Risk Assessment
Some points to consider:
The installation and maintenance of air conditioning units 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 Australian Standards, which offer practical
guidance on these health and safety issues. Compliance with these regulations will require appropriate work practices,
equipment, training and qualifications of workers.
Seeley International provides the following information as a guide to contractors and employees to assist in minimising
risk whilst working at height.
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.
A risk assessment of all hazardous tasks is required under legislation.
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?
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 difficulty, how can they summon help? (Call some
one 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?
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 firm, 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 influence of drugs
or alcohol?
Are there any special conditions to consider i.e. excessive roof pitch, limited ground area, fragile roof, electrical power
lines?

Cooler location
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.
Always locate the cooler where it will receive a plentiful supply of fresh air; NOT in a recess where it may be starved for air or
where the air is polluted.
Air exiting the exhaust hood is warm and heavily laden with moisture. Ensure the cooler’s exhaust outlet location will not cause
corrosion or damage to other nearby items.
Allow adequate access to and around the cooler for maintenance. Provision must be made for access to electricity, water
supplies and drains. Note: Do you need to discuss the installation of items like safety anchor points with the customer?
• Ensure the location is a minimum of:
3.0m from a solid fuel heater flue,
1.5m from a gas flue,
5.0m from a sewer vent
Rear = Min from a wall, at sides
to allow easy access for maintenance and core replacement.

Industry standard support frames can be used with this cooler.
Recommended steel specification:
50*50*3mm RHS Galvanised or Painted
The cooler will be delivered wrapped in a plastic stretchwrap film which will need to be removed before installation. A
small bag of Installation components along with the exhaust hood sheet metal components can be found under the lid of
the main cabinet of the cooler. The lid will need to be removed and the exhaust transition components assembled and
fitted to the lid before re-installing the lid assembly back onto the cooler. The wall control and communications cable,
along with ancillary mount plates, fasteners and drain adaptors will need to be placed aside for later connection.
The cooler has in-built fork-truck tyne openings in the base for ease of movement. The openings can also be used with
lifting straps or slings (refer diagram & see below)
The cooler may be lifted either by fork-truck or crane with slings. The method for lifting by crane is by lifting straps through
the cooler base fork-truck tyne openings. Do not attempt to lift using any cabinet features or by retro-fitting lifting lugs. The
cabinet may be damaged and/or lift safety compromised.
It is recommended to use a spreader bar on the straps or slings and/or to protect the upper edges of the cooler with a
corner protector beneath the lifting straps to avoid any damage to the cabinet during the lift.
Waffle pads are recommended to be used under each corner of the cooler. Pad size approx. 200 * 200mm. Use industry
standard methods of fixing to the building structure.

Duct Connections
Exhaust Duct requirements
Exhaust Transition Assembly
Vibration absorbing flexible connections are recommended for all duct connections to the cooler, for any ducts that are
attached to the building structure.
All ducts attached to the flexible connection must be independently supported.
Ensure the exhaust discharge opening is located and oriented in such a way as to avoid exhaust air re-entering the cooler
inlet. Exhaust air is warm and heavily laden with moisture.
The exhaust transition is supplied in knock-down form; its components are to be found beneath the lid of the cooler after
shipping. This requires the installer to remove the lid of the cooler, remove the componentry and assemble the Exhaust
Transition and fit it to the lid with the supplied fasteners, fit the Inlet Air Filter or Safety Grille, then refit the Lid/Exhaust
assembly back onto the cooler. The flange of the exhaust transition must be fitted beneath the lid of the cooler. Use a high
quality sealant that is neutral cure, flexible and has good UV and weather resistance between the exhaust transition
flange and the lid. (Fig. 3)

Inlet Air Filter Assembly
Climate Wizard coolers are supplied ex-factory with an Inlet Air Filter assembly. Should the Filter Assembly not be
required an optional Safety Grille is available and must be fitted for safety reasons.
The Inlet Air Filter assembly is supplied in separate cartons when shipped with the Climate Wizard. This requires the
installer to remove the lid of the cooler, remove the filters from their shipping position in the frame, fit the filter frame to the
cooler, secure the cowling top and sides to the filter frame and cooler, slide the filters back into the frame and secure the
cowling front access panel with the supplied fasteners. Refit the Lid/Exhaust assembly back onto the cooler, over the
flange of the Inlet Filter Cowling.
Fit filter frame to inlet of cooler
Fit the Filter Cowling top and sides
to the Filter Frame and Cooler.
The top lip of the filter cowling (shaded, Fig. 3) must locate inside the lid of the cooler (Fig. 4), this may require the lid to
be unfastened (if already assembled) and lifted or, alternately, assemble the lid to the cooler after the filter assembly and
cowling is fitted. Insert the filters to the filter frame. Fit the front panel of the cowling onto the cowling assembly.

The following specifications for water supply are required:
The installer must provide a manual 1/4 turn ball type shut off valve (do not use a stop cock) in the water supply line adjacent to
the cooler, subject to local plumbing regulations. This allows the water supply to be isolated whenever work needs to be done
on the cooler.
Climate Wizard requires a permanent water supply to be connected. 1/2 inch BSP male connection point provided on the
cooler (see diagram), suitable for compression fitting. Pressure range required - 100 kPa - 800kPa at flow rate of 20 L/min.
Water Connections : ½” BSP Female threaded fitting required
Water Supply :100 - 800 kPa @ 20L/min (115 psi) MAXIMUM
Water Supply Temperature : 40°C MAXIMUM

Control Schemes
Climate Wizard coolers are supplied from the factory with one (1) Wall Control and a 20m control cable. This makes it
possible for the Cooler to be controlled independently and automatically from the zone to which it is delivering cool air. No
additional equipment is required. The Wall Control incorporates a thermostat that regulates fan speed to maintain indoor
temperature within 0.5 C of the set temperature. Climate Wizard Coolers are also supplied with an interface to enable
the cooler to be controlled from an external location, using a BMS system.
Whatever control option is being used, the inbuilt Climate Wizard water management and fault monitoring features are
fully operational. The Climate Wizard control scheme incorporates some Parameters that can be altered to other settings
if the default settings are not suitable.
Individual coolers can be controlled completely from within their cooling zone using the Wall Control-thermostat supplied.
A 20m connecting cable, plugged each end is supplied. 40m cables are also available on request. - p/n 833897.
Maximum permissible cable length between the Wall Control and the cooler is 40m.
No interconnection between coolers to achieve ‘Group control’ is possible.
Climate Wizard Coolers are supplied with an ‘Interface PCB’.

valve opens to refill the reservoir.
Will sense conductivity down to 9 uS (about 4ppm) (ie: rain water)
Water Usage sensing:
Number of times that reservoir is filled from bottom probe to top probe is counted. When this count reaches 8, a
drain cycle is initiated.
Drain valve opens until water level falls below bottom probe, then valve closes immediately, and inlet solenoid
valve opens to refill the reservoir.
Pumps enabled to run at any time during the salinity drain cycle.
The Chlorinator is a pair of specially treated plates. When energised and submerged in water, electrical current flows
between them, generating chlorine. There are two (2) sets of Chlorinator plates in the Climate Wizard. Chlorine is known
to kill bacteria in water supplies and the Climate Wizard Chlorination system is designed to minimise bacteria levels within
the cooler.
Chlorinators are active at all times that the cooler is in COOL mode, AND the water level is above the bottom
probe, AND the pumps are not running (8 minutes in every 9 minutes), AND the salinity control is not sensing (50
seconds in every 60 seconds).

Control Schemes
To enter Parameter mode using a Wall Control, the following process must be carried out within Four (4) minutes
of mains power being applied to the cooler. If unsure of time since the last Mains Power “ON”, remove Mains
Power to the cooler (Isolator Switch or Circuit Breaker) for a minimum of six (6) seconds so the mode can be
entered.

Whilst wall ontrol is OFF, push and hold “ ” for minimum three (3) seconds. After three (3) seconds whilst still holding
“ ” button press the “ ” button. (If “ ” button is pressed before three (3) seconds, nothing will be on the display.
If “ ” button, is continued to be held subsequent presses of “ ” button will allow access).
When parameter mode has been entered, screen will display “A1” and “Param”. Pressing “ ” or “ ” buttons will
scroll through parameters “A1” to “B3” (Refer to table below for factory settings).
To view parameter number set in wall control press “ ” momentarily. Figure “A#” on screen will change to number set,
and “Param” will change to “value”.
To alter “value” of selected parameter press “ ” or “ ”. Numbers will change to show different values parameter
can be set to.
To store the selected value, press “ ”. Screen will go blank momentarily as wall control stores parameter change, and
returns screen to “A#” and “Param”.
To exit parameter mode or escape from an alteration without storing a change press “ ” button instead of “ ”
button. Remember, once step five (5) has been carried out, new parameter change is permanent until again altered.
If no buttons are pushed on wall control, after three (3) minutes screen will reset to “OFF” state. Procedure to enter
parameter mode must be re-initiated.

CAUTION! Always make sure there are no electrical cables, gas or water pipes, or the like, behind where
you intend to drill.
INSTALLATION
Wall Control Installation
Locating the wall control
(Stand Alone & Supplementary Cooling)
The wall control should be placed approximately 1.5 metres above the floor, in the general area of the cooled zone.
:
•Avoid direct sunlight exposure.
•Avoid mounting on external walls.
•Avoid mounting the wall control near heat sources such as room heaters, stoves and TV’s.
• Do not locate in the direct airflow from the duct outlets.
• Do not locate in strong drafts or in dead spots such as corners and confined spaces.
• Always seal the cable entry hole in the wall. Hot air coming through the wall may interfere with the temperature
measurement.
Placement of the Wall Control is critical for correct functioning of the inbuilt thermostat (incorporated in the wall control). The
following points must be taken into consideration
Fixing the wall control bracket
to a plasterboard wall
Use the bracket as a template.
1. Drill the 16mm hole for the wall
control cable
2. Drill the 5mm holes for the wall
plugs.
3. Insert the wall plugs into the
holes. Align and screw the
bracket into position using the
supplied screws.
Fixing the wall control bracket to
a brick wall
To mount the wall control bracket
on a brick wall, follow the previous
instructions (Fig 1) using the wall
plugs and screws provided.
Note that the wall plugs require
6mm holes. Mount the wall
following the procedure in Fig 3.
control
1.Pull the wall control cable through
the larger hole and plug it into the
wall control.
2. Feed the excess cable back into
the hole and seal. Slide the wall
control over the protruding bracket
tabs.
3. Pull the wall control down so the
bracket tabs engage and locate
with the keyway slots on the rear.

Running the wall control cable to the wall control
!
Using the loop on the end, draw the cable through the wall cavity to the hole made at the wall bracket. Carefully remove the
tape from the cable loops and check that the plug has not been damaged. Connect the cable to the wall control and mount the
wall control onto its bracket.
Important Take care not to damage the cable or plug during this process. Always seal the cable entry hole.

Setting the Air Discharge Damper
AIR FLOW BALANCING
THIS PROPORTION IS CRITICAL TO ACHIEVING SATISFACTORY PERFORMANCE.
In order for the Climate Wizard to produce cool air it is mandatory that some of the inlet air is forced to return through the
heat exchanger and be exhausted to atmosphere. Therefore only a proportion of the total inlet air is delivered into the
cooled zone; it's about 50/50.
The supply air transition is equipped with a set of dampers that can be adjusted to 'balance' the proportion of supply and
exhaust air streams. The damper is factory set, but may need to be re-adjusted during Commissioning depending on the
resistance of the duct system.
Underneath the supply air transition is a manual quadrant damper lever with locking screw (see photo below). There is
also a hole in the right hand side of the supply air transition suitable for manometer tubes for measuring pressure (see
diagram below). Pressure measuring should be carried out using an accurate instrument, either electronic or
“inclined tube manometer”.
a. Connect all external ductwork to the Climate Wizard in preparation for balancing the system.
b. Open fully all supply air outlets in the entire ductwork system.
c. Start the Climate Wizard in MANUAL and VENT modes on full speed.
d. Adjust the Climate Wizard damper until the pressure in the transition stabilises as follows:
CW-H10 240 Pa
CW-H15 215 Pa
e. Proceed to balance the external duct and outlets in your usual manner.
f. Check and if necessary re-adjust the Climate Wizard damper back to the above values.
g. Lock the damper in its final position
NOTE:
DO NOT GUESS.

Climate Wizard Cooling Applications
Climate Wizard is designed to be used in 3 different types of applications:
- in cases where the Climate Wizard is the primary source ofAir Conditioning for the building.
- in cases where the Climate Wizard is used to augment the capacity of the existing air
conditioning system, or to extend its reach into the building, or to greatly reduce the energy consumption of the Air
Conditioning plant.
- in cases where the Climate Wizard is used to pre-cool the fresh air supply to new or existing
refrigerated air conditioning plants in order to prolong the life of the plants, to save significant energy, and to greatly reduce
demand on existing infrastructure which becomes over-stressed in heat-wave conditions.
In each application type, remarkable energy savings can be achieved compared with conventional Refrigerated Air
Conditioning.
