- Page 8 5. LOADING AND HANDLING Appropriate equipment should be used to load, un-load and locate the unit in its operational location. Considera- tion of the products size and weight should be taken ensuring that any equipment (such as fork lifts) meets relevant national standards.
- Page 9 Loading and handling min PL +30 min PL +30 KEC 80/95 KEC 80/95 All large units have recommended points for use when fork or strop lifting, both are clearly marked. Care should be taken to protect the unit against mechanical damage while unloading. Extreme care must be taken to protect coil connections and fins.
- Page 10 LOCATION GUIDANCE AND INSTALLATION Unpacking KEC and KMe Remove the box/crate packaging On most KEC units remove the draintray by removing the four fixings and then fit the hexagonal drain connection and gasket into the hexagonal well inside the draintray. Hand tighten this assembly using the knurled nut on the outside. When the cooler is in position ensure that the drainpan is dropped down into the operating position before tightening its fixings.
- Page 11 Location guidance and installation Unpacking DSR and LSR Remove crate packaging/plastic wrapping On all DSR and LSR units the draintray is already fitted, remove the four fixings securing the unit to the wooden pallet and place into position using the location guidance.
- Page 12 Unpacking SM Remove plastic wrapping On all SM units the draintray is already fitted, remove the fixings/metel brackets securing the unit to the wooden pallet. Place into position using the location guidance Unpacking TEC Searle Air Cooler...
- Page 13 Location guidance and installation The location of the unit should be carefully selected to ensure that: Air distribution from the cooler is not adversely affected by obstructions and is appropriate for the size and shape of the room, optimum air distribution should be targeted. Product loading must be in accordance with good refrigeration practice.
- Page 14 Mounting the unit Warning In case of improper installation, leak of working fluid can occur during operation of the cooling equipment, this can lead to injuries or damage to yourself or property. On all coolers mounting slots are provided, make sure the location guide is observed before you hang the unit Only fix the unit using the mounting slots provided (refer to unit dimension drawings for slot measure- ments)
- Page 15 Installation and Location guidance Mounting a TEC TEC’s that are wall mounted an additional drainpan needs to be fixed to the cooler (a kit is available separately). This is achieved by removing the panel fixing screws around three sides of the air-off face, offering up the verti- cal drainpan and replacing the screws through the holes in the drainpan, securing it in place.
- Page 16 7. PIPEWORK Pipework to and from the cooler should be suitable for: • Working fluid (guidance can be provided by Kelvion representative or pipe suppler) • Atmospheric conditions • Maximum operating pressure including relevant safety factor Damage caused by incorrect installation will invalidate the manufacturer’s warranty obligations.
- Page 17 Condensate drainage 8. CONDENSATE DRAINAGE & CONDENSATE PUMP KIT OPTIONS In most cooler units once the unit is in place the drain tray MUST slope downwards towards the drain connection. Ensure that drainline size is equivalent to that of the drain connection and that it has an adequate fall. It is essential that the drain- line includes a trap, fitted outside the coldroom.
- Page 18 1.0 bar On models TEC1, TEC2 and TEC3 an internally equalised TEV may be used. On units TEC3.5 to TEC8 an externally equalised TEV must be used and an allowance of 1 bar for R134A and 1.5 bar for R404A, R407C, R410A and R507A should be made for the pressure drop across the distribution system.

EVACUATION Fluid coolers using water or water-based solutions must be protected by adding anti-freeze in sufficient concentration, as it is not possible to drain the system completely. Note: The heat transfer properties of a fluid vary with the concentration of additives.
- Page 22 Kelvion would recommend as general rule that each cable or group of cables will be supported at no greater than 500mm intervals; but if national legislation recommends otherwise this should be followed. Cable size is determined by the motor current, with the necessary duration for unit operating temperature.

- Page 34 15. DEFROST Air cooling evaporators whose surface temperature is lower than the dew point of the air they are cooling will accumulate moisture from the air. When the surface temperature is below freezing, this moisture will be deposited in the form of frost and eventually, if left, will restrict heat transfer and air flow.
