SAFETY The main safety aspects concerned with your unit cover two main areas, the operation of the equipment and the applications for which it will be used.

1.1

Equipment Operation . As with any thermal device you must take precautions not to burn yourself on any of the potentially hot surfaces that it is possible to touch when the door of the unit is open during any period of operation. Always wear hand and arm protection when loading or unloading the equipment and take care not to touch any hot surfaces with any unprotected part of your body. Always set the over temperature safety limiter to the correct level as described in section 4.2.7. This will help to protect both the equipment and possibly any loads that are inside the unit.

1.2

Applications . Think very carefully about how anything you will place inside the unit is going to react when subjected to the temperatures that you are going to use. Obviously the flammability of any substances you will place inside the unit is one major concern, together with any dangerous vapours that the substance may release into the local environment when heated.

PRODUCT OVERVIEW

2.1

General The term Kingfisher covers a range of Solution Warming Cabinets and Blanket Warming Cabinets. All models are electronically controlled and have chambers manufactured from stainless steel. Solution Warming Cabinets are fan circulated while the Blanket Warming Cabinets are natural convection. The temperature is controlled by an electronic controller which has an easy read illuminated digital display. The Warming Cabinets are simple to operate. All controls are housed in the top mounted control panel. Samples are protected by means of an adjustable, over-temperature limiting device, which can be set at any desired temperature above the primary set point. To further protect the product and its surroundings, all Kingfisher models are fitted with a thermal fuse. NOTE - Blankets must never be stored in a Solution Warming Cabinet.

INSTALLATION INSTRUCTIONS

3.1

General Checks Upon receipt of the equipment unpack it carefully and check that no damage has occurred in transit. Remove any packing from the inside of the unit. Check the identity plate on the rear of the equipment adjacent to the power inlet and make sure that the machine operating voltage matches the supply to which it will be connected.

3.2

Positioning

3.2.1 Check the weight of the unit in the Product Overview section and use a careful and thoughtful approach when moving the unit to its location. 3.2.2 Prepare a level area large enough to accommodate the unit adjacent to a power supply connection and using great care to avoid the risk of an accident, position it in this area. 3.2.3 Take care not to obstruct any of the ventilation slots or louvers in the casework of the equipment. 3.2.4 Check when positioning the unit that the power input lead is not pressing against any wall or partition that may be adjacent to the rear of the case, as this may damage the cable. 3.2.5 A clearance of at least 50mm is recommended from the rear of the unit to any adjacent walls or surfaces for adequate fan ventilation.

10

3.3

ELECTRICAL CONNECTION

3.3.1 Double check the machine identity plate and ensure the operating voltage matches the supply to which it is to be connected. 3.3.2 The power supply must have a protective earth, which is known to be in good working condition and of the correct current carrying capacity.

This product is fitted with a moulded plug to BS1363/A. If a different type of plug needs to be fitted, this can be done without affecting warranty. We recommend a suitably qualified person to carry out this work.

OPERATING THE EQUIPMENT - INTRODUCTION

4.1

Controls The controls are mounted on the front of the units, above the door. Apart from the power switch, which is mounted at the rear to prevent accidental switching. The controls are:

4.1.1 Power Switch This is the main power on off switch. The switch indicates the power on position when the side of the switch marked with the number 1 is pressed in. Similarly the power is switched off when the side of the switch identified with a 0 is pressed in. 4.1.2 Power Indicator The green indicator illuminates when power is on. 4.1.3 Heater Indicator The amber indicator illuminates when heater is receiving power. When the system is controlling the indicator it will cycle on/off. 4.1.4 Temperature The temperature is controlled by an electronic controller indicator, which has an easy read illuminated digital display. The actual running temperature is shown on the L.E.D. display and a button on the controller provides visual indication of the set point. The controller switches the heaters via a solid-state relay. The control sensor is a 100 ohm P.R.T. 4.1.5 Over Temperature Safety Limiter Indicator A red indicator is provided to indicate that the over temperature limiter has gone into operation. 4.1.6 Over Temperature Limiter A control knob is provided for setting the required over-ride temperature. This will take control in the event of an over temperature. The knob is fitted with a slot for adjustment to prevent inadvertent turning.

4.2

Operation

4.2.1 Place the power switch to the ‘On’ position. 4.2.2 Press the button marked * on the temperature controller. The digital display will now read ‘Set Temperature’. Adjustment of the temperature can now be made by pressing either of the buttons marked with the arrows to either increase or decrease the set temperature, (the * button must be kept depressed during this process). On releasing the * button the controller will indicate actual chamber temperature and this will rise to achieve the set value. 4.2.3 Ensure that the Over Temperature Limiter control is set to the maximum scale number. 4.2.4 Allow the unit to stabilise at set temperature, ie. When the heater indicator light starts to cycle on-off. 4.2.5 Reduce the operation limiter control slowly until the red lamp illuminates. 4.2.6 Increase the limiter by ½ - 1 division. The red lamp will go out. 4.2.7 The unit is now operational. 4.2.8 For alternative means of temperature measurement (e.g. thermocouple, resistance bulb), probe leads may be fed into the cabinet interior via the top tubular.

OPERATOR MAINTENANCE

5.1

The main duty for operators is to keep the inside of the chamber clean. Ensure that any spillages are cleaned up quickly.

5.2

Should the door latching arrangement ever need adjusting, this may be achieved as follows: With the door open, the door locking striker can be seen in the right hand oven style. Release the striker locking nut and screw the striker in or out as required in order to attain a good door seal. Re-tighten the locking nut.

5.3

Fault Finding No display on controller Check if power on light is lit, if it isn’t check main switch at rear of cabinet is on. Check mains supply to cabinet. If power on light is lit, Check for mains volts between terminals 7 and 8 on controller. If there is mains volts then controller is faulty and should be replaced. If there is no mains volts check terminal fuse and fuse F2. Before replacing either fuse reason for failure must be checked. Over Temp light cycling on/off Check set point on controller hasn’t been increased above temp limiter setting. Check SPI output LED on controller is cycling, 6 volts D.C between terminals 3 and 4 on controller. Check that when LED on SSR is off there is no mains volts between wire no’s 8 and 5. If there is SSR is faulty and should be replaced. Circulating fan not working (if fitted) check for mains voltage at fan. No Heat Check fuse FI hasn’t blown. Reason for failure must be checked and rectified before replacing fuse check when LED on SSR is lit there is mains volts between wire no’s 8 and 5. Check heater for continuity.
