SECTION 1 USER INTERFACES
The Cooling Units have their own independent controllers. These are used to change the settings of the units such as the temperature setpoint.
If there is an issue with the unit the display on the controller will display a message/ code highlighting the issue. Check the manual for a description of this code.
NOTE: Only a competent individual should change the setting or attempt repairs on these units. Changing the setting will affect the products performance and may result in damage to items stored in the product.
A Dixell Display forms part of the High-Low Alarm and the Supervisor Panel. (Please refer to the drawing to determine which items your product has.) The temperature displayed is the temperature detected by the probe connected to it, not from the cooling unit. This controller cannot directly control the cooling units.
It can be used to set temperature alarms on the High Low Alarm & Supervisor Panel. It can be used to setup duty standby/assist on the Supervisor Panels.
NOTE: If changing alarms ensure they do not conflict with the setpoint of the cooling units.

SECTION 3
COMMON ISSUES
Thank you for taking one of our products. We hope it meets your expectations. Below we have outlined some of the common issues we have encountered regarding incorrect use of our products.
NOTE: It is vitally important that regular preventative maintenance (PM) is conducted on this product by a competent person and that the product is kept clean and free from excessive ice buildup.
•Please ensure the door is tied open before bringing a load up the ramp. This will ensure that the door will not accidentally close when entering/exiting the product which could cause damage to the door, the user and the items being loaded into the unit.
•Please ensure the ramp is clear from debris before opening the door as items such as stones, bolts etc. can catch and tear the sweeper gasket. Never open the door with a pallet truck or trolly already on the ramp.
•The doors on our product are large so please conduct a risk assessment before opening the product in high winds.
•Because there is a temperature difference between the space inside our product and the ambient surrounding the product there will be a pressure difference. This can make it hard to open the door. There is a pressure release valve installed to minimise this, but please ensure you open the door with the black pull handle as oppose the safety locking handle. This is to prevent damage to the locking handle and to make it easier and safer for the user to open the door.
•If the door is excessively hard to open it could be that the product is no longer level, this can be checked with a spirit level and should be checked as part of the PM. If the product is not level, please give us a call and we can advise on how to rectify.
• It is the customer’s responsibility to regularly check alarms and emergency lights to ensure they are in proper working order and providing a safe working envirnment for the product users.
• If the emergency button has been activated, it must be depressed for the alarm to stop and the refrigeration units to restart.
•On low temperature products there will be a trace heater in the door to prevent ice build-up. This will make the door hot to the touch. If the trace heater is damaged it can result in ice build-up of the door making it difficult to open.
•Ice build-up inside the unit is almost, always due to excessive door openings. It is important that door openings are kept to a minimum and installed curtains are left in place. Ice build-up can damage internal components such as the lights and can create a health and safety risk. Excessive door opening also affect the efficiency of the product and puts the load in the product at risk. We recommend that a thaw is conducted at least once a quarter to remove ice build-up with best practice being a weekly thaw. This can be simply done by turning off the product and leaving the door opened. The process can be quickened with the Thermo King product by changing the set point to a positive temperature (+30°C) and keeping the door closed. Please refer to the cooling unit manual for details on how to turn on the defrost heaters.
•Air flow within the product is perhaps the most important factor to consider when loading it with goods. If air is able to flow sufficiently, your container will function optimally, and your load will reach temperature quicker and more evenly. When loading the product make sure the supply and return air of the cooling units are not blocked and that items are not stored above the load limit line. We recommend that you store your items in such a way so as not to limit the airflow e.g., using egg crate spacers.
•The product will work harder, and make the most noise, when getting to temperature. This will occur after the product is turned on, after door openings and after loading with new items. We recommend developing a procedure of best practice for loading your goods e.g., first in first out for goods.
•It is important that the area around the product is kept clear from clutter and the unit is kept clean. The cooling units need space to work correctly and to prevent issues such as short cycling occurring. Organic growth on the units can cause paint damage as can bumps and scrapes from loading items against the product. It is important that if you have an issue with the product that the engineers can access all areas of the product easily to make the repair.

SECTION 4
CLEANING & MAINTENANCE
Note: Stop cooling/heating unit before cleaning!
Use only alkaline cleaning fluid that is designed for aluminium.
The door gaskets will need to be clean to provide a tight seal.
When necessary, use a soft brush for additional cleaning.
The maximum water temperature for cleaning inside and outside the container is 80°C [176 °F].
When using high pressure or steam purifiers, maintain a minimum distance of 300mm (12.0in) to the cleaning surface with the spray nozzle. (Maximum pressure 100 bar [1,450 psi] and maximum spray time on same spot 30 seconds).
Making sure your condenser coils are spotless will ensure the unit chills appropriately, hitting the mark in terms of optimal energy efficiency.
NOTE: We recommend you conduct your own risk assessment before starting to clean the product.
Our product needs to be checked regularly to ensure the correct functioning of the units. Make sure you don’t miss your maintenance appointments as these are a critical preventive measure in keeping the product working correctly. At CRS, we operate a 24-hour emergency call out service to all units that are on hire and under service contracts. Please check your contract before contacting CRS to see if you have a plan in place.
Check for temperature fluctuations. If you spot something strange in the way your unit operates, check this with an engineer as soon as possible to avoid damage to your load. If a malfunction occurs:
1.Do not open the doors.
2.If the product temperature is critical you can telephone our 24hr Breakdown Service stating:
•The fleet number: Large black number prefixed with a letter C, M, L or CT.
•The company name, address and location of product.
•The site contact name and telephone number (to be be used to ring you back).
•Details of breakdown.
Please note that the temperature will rise in coldrooms when on defrost or when fresh product has been loaded into them. Try to avoid loading warm products into the coldstore (this is not an issue with blast freezers).
The customer should regularly check safety devices to ensure they are working properly: temperature alarm, emergency light, personnel alarm, safety locking handle.
NOTE: We recommend you implement a schedule for checking the units regularly, especially if the unit is in a remote location.
