IT Cooling LogiCool™ OnRak Installation IMPORTANT If the unit is dropped, it should immediately be checked for damage and reported to Airedale. Positioning The mating frame is attached to the customers rack. An air tight seal must be placed between the mating frame and the data enclosure. The OnRak is then lifted onto the hinges and as it’s closed will produce an air tight seal. CAUTION Airedale will accept no responsibility for mishandling during the positioning of the equipment.
LogiCool™ OnRak Fitting Hinges IT Cooling The OnRak needs to be lifted vertically to ensure that the assembly fits onto the hinges. must be taken whilst locating the lift-off hinges together prior to lowering into place. Active CabinetCareExhaust Illustrations for guidance only Data Rack Feet 24 The data rack feet must be used prior to the unit being mounted to the rack. This takes the weight off the castors.
IT Cooling Rack Support Wheel LogiCool™ OnRak A support wheel is provided for fitment under the Onrak door. This is to be at the same level as the door rack feet. The wheel is to be fitted ensuring that it has free movement.
LogiCool™ OnRak IT Cooling Door Latch Mechanism Active Cabinet Exhaust CAUTION 26 Ensure that the door latch mechanism does not snag on the sheet metal. Distortion of the door can occur if the latch is forced IT Cooling Technical, Installation and Maintenance Manual :6912497 V1.5.
IT Cooling Floor Cut Outs LogiCool™ OnRak To enable the flexible pipework installation the following minimum cut out is required in the floor tile below the unit. Contact your grommet supplier for exact sizes. This ensures that the pipework does not get obstructed causing additional strain on the fittings. Floor Tile Cut Out Dimension (Minimum) Mating Frame Cut Out IMPORTANT Ensure that the mating frame and floor is sealed for correct unit operation.
LogiCool™ OnRak Water Connections IT Cooling Two flexible, stainless steel braided hoses connect the coil to the chilled water supply. flexibility of the hoses allows the OnRak door to be easily opened for accessing Active CabinetThe Exhaust hardware within the server cabinet, without the need to disconnect services or disrupt cooling..

Apply small amount of oil to top of olive. 4 3 Insert into fitting (remove any excess sealant with a cloth). Undo and remove pipe from fitting. Apply small amount of pipe sealant to leading edge of olive that will be inserted into fitting. 5 6 Mark two alignment marks on fitting.
IT Cooling Chilled Water Valve (3 Way) LogiCool™ OnRak The chilled water valve has an indication of flow on the stem. The actuator is securely attached to the top of the valve so that when there is a demand for cooling the valve opens allowing water to flow through the coil. No demand, the water goes through the bypass (0 VDC no demand, 10 VDC 100% demand).
LogiCool™ OnRak Chilled Water Valve (2 Way) IT Cooling The chilled water valve has an indication of flow on the stem. actuator is securely attached to the top of the valve so that when there is a demand Active CabinetThe Exhaust for cooling the valve opens allowing water to flow through the coil. No demand, the water is shut off allowing no water to enter the coil (0 VDC no demand, 10 VDC 100% demand).

Mass 1kG a 105 CAUTION b 85 c 106 f 71 g 46 l 28 s 42 The solenoid valve electrical connection must be a maximum of 3m away from the customer terminal box. This is to ensure EMC Compatibility. Coil Water Connections Swivel pipework connection to coil Coil connections are brazed at Airedale. Full pressure testing to 20Barg is carried out prior to unit despatch.
LogiCool™ OnRak Customer Terminal Box IT Cooling The customer terminal box is attached to the coil guard during shipment. Carefully remove this and feed the box through the hole in the mating frame. This must be done after the door is fitted to the mating frame. Active Cabinet Exhaust Dual Power Supply The dual power supply can be either fitted into a rack or fitted in the floor void under the server rack. The following procedures apply.
IT Cooling IMPORTANT LED Indicators LogiCool™ OnRak Attach the earth strap to the rear of the power supply unit. Locate the Dual power supply between the cable support guides of the server rack. Secure the unit with screws supplied by your rack manufacturer. Attach the incoming fused power supplies. Fit power supply retaining clips. Attach the outgoing power supply to the customer terminal box. Do not route the outgoing cable through the area occupied by the pipework.
LogiCool™ OnRak Under Floor Dual Power Supply IT Cooling The under floor Dual Power supply is located under the floor void. The supply is to be mounted securely. Provision is made for fixing to the floor or associated supports. Attach relevant earth bonding to the power supply. Active Cabinet Exhaust Attach the incoming fused power supplies. (The Primary supply for this supply is always “A”.) Fit power supply retaining clips. Attach the outgoing power supply to the customer terminal box.
IT Cooling Uninterrupted Power Supply LogiCool™ OnRak The UPS shall fit within the server cabinet and shall be the same dimension as 1U/ 2U rack. Various capacities are available. Installation of the UPS is rack mounted. Full information of the installation is supplied with the UPS. The UPS can be personalised to the application (response times etc) through a computer. This connection can be either RS232 or USB.
LogiCool™ OnRak Rack Pressure Management IT Cooling The rack pressure management comes in two parts for onsite fitment. Part one A static pressure ring (-ve negative pressure) is fitted behind the coil guard. An airflow tube comes out from the controller and is then routed around the drip tray.
IT Cooling Rack Sealing LogiCool™ OnRak The rack must be sealed so that air does not bypass the servers. The racks must not have any ventilation holes such as a perforated roof. Any space within the server racks that are redundant must be sealed with blanking panel (usually supplied in 1U and 2U). Figure 1 Wrong Cabinet not sealed CAUTION OnRak OnRak The heat leaving the servers must be sensed by the OnRak to ensure correct operation.

LogiCool™ OnRak IT Cooling Rack Pressure Management The fans will operate to maintain the “air off” temperature as long as the pressure remains within the normal operating range. However, if the pressure within the server space changes beyond the high or low differential set-points, the fans prioritise pressure control to bring the server pressure back within limits, at which point normal temperature control resumes.
IT Cooling LogiCool™ OnRak Commissioning Procedure General To be read in conjunction with the commissioning sheets provided. CAUTION Please ensure all documents have been completed correctly and returned to Airedale technical support to validate warranty. CAUTION All work MUST be carried out by Technically Trained and competent personnel. The equipment contains live electrical and moving parts, Isolate prior to maintenance or repair work.
LogiCool™ OnRak IT Cooling Commissioning Procedure Active Cabinet Exhaust Fan Removal Alarm Check alarm state when a fan goes offline. Differential Pressure The differential pressure switch should cause the OnRak fans to increase / decrease when the server fans are active. One of the fans can be removed to allow the differential pressure to be recognised if the server load is low.
IT Cooling LogiCool™ OnRak Maintenance Changing EC Fans The fans are designed as plug and play “hot swap” enabling the fans to be changed without the need to disconnect the power from the entire unit. Removing the 4 security fixings enable the fan to be removed The unit has automatic disconnect sockets to the fan motors. The remaining fans will increase speed to compensate for the fan being serviced (only in N+1 configuration) CAUTION The unit will remain live up to the fan disconnect socket.
LogiCool™ OnRak IT Cooling Operational Maintenance checks Active Cabinet Exhaust Owners Responsibility To ensure that the unit can be maintained correctly the following requirements are required. Maintain a safe working environment around the unit, free from obstructions and debris. The unit shall follow the following maintenance regime as a minimum.
