UNPACKING
UNPACKING ON ALL KEC AND KME MODELS
1. Remove the box/crate packaging.
2. On KEC units remove the drain tray by removing the four xings and then t the hexagonal drain connection and gasket into the hexagonal well inside the
drain tray. Hand tighten this assembly using the knurled nut on the outside. When the cooler is in position ensure that the drain pan is dropped down into the
operating position before tightening its xings. The KME units will have a cable tie xing the drain tray along the side of the unit.
3. Place into position using the location guidance.
UNPACKING ON ALLTEC MODELS
The location of the unit should be carefully selected to ensure that:
4. Air distribution from the cooler is not adversely eected 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.
5. Air entering the cooler is not obstructed.
6. The unit must be installed level in both directions.
7. Maintenance access should be considered when locating the product, including adequate space for heater withdrawal when appropriate.
8. The unit is not subjected to physical loads.

• Do not mount evaporators above or adjacent to door.
• Do not restrict the air inlet (‘A’) to the evaporator .
• Air stream should be unobstructed by beams, lights or other store products (generally down aisles towards the door).
• Evaporators are designed to be ush and level ceiling mounted. Mounting rods and support structure should be designed to take the full operation weight
including tted accessories, refrigerant charge, ice and condensate .

PIPEWORK
Pipework to and from the cooler should be suitable for:
• Working uid (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.
Pipework to and from the coolers should be selected to suit the application and not the connection size of the unit. Pipework sizes should be selected to ensure
pressure drop does not exceed an equivalent of 2K at full load conditions.
Pipework should be supported independently from the cooler unit in a way that prevents the transmission of vibration to the units. A qualied engineer should
install the refrigerant pipework to a high standard of refrigeration practice. All pipework used must be clean and to refrigeration quality, all cuts should be made
using a pipe cutter, never a hacksaw, and care must be taken to remove all burrs and swarf.
Braze using silver bearing brazing rod and ensure that all joints are cleaned before brazing. During brazing care should be taken to ensure that all components
near joints should not be excessively overheated, a wet cloth should be applied where necessary. Dry nitrogen should be passed through the pipework during
brazing to minimise oxidisation.
WARNING!
Use appropriate PPE (personal protection equipment) during pipework, refrigerant charging and commissioning. During brazing ensure
the temperature of coils with vinyl coated ns does not exceed 300°F as toxic fumes would be produced . When brazing and leak testing
are complete the suction line should be insulated with 3/4” thick Class ‘O’ insulation. The unit has been thoroughly tested during
manufacture however after on site brazing is complete all pipework should be pressure tested for leaks to maximum of 1.3 capacity pressure
Be aware of the below hazards during pipework and refrigerant charging:
IN THE EVENT OF INJURY, SEEK MEDICAL ATTENTION IMMEDIATELY.
It is the responsibility of the installer to ensure piping to and from the condenser is suitable for the application, although guidance from your Kelvion
representative can be provided.
Unless otherwise specied, twin section units should be connected in parallel to each other, not in series; failure to do so will result in excessive uid pressure
drop and a corresponding loss in performance.
All pipework and ttings should be pressure tested upon installation completion in accordance with relevant regulations or legislations. Any pressure test should
not exceed the unit’s maximum operating pressure or the pressure rating of any safety devices.

STORAGE
• To avoid contamination and corrosion, the units must be stored in dry and clean area.
• Storing for long periods is not recommended, but where this cannot be avoided the fan motors must run for a minimum of 2 hours per month. Failure to do
so will invalidate manufacturer’s warranty.
GENERAL
Upon receipt, the units should be visually inspected, any transport damage and / or missing parts must be recorded on the delivery note and the manufacturer
notied in writing within seven days. Please ensure:
• The pipework shows no signs of damage.
• The fan set / motor terminals box lids are not cracked or showing signs of obvious damage.
• The electrical screw terminals in control panels and motor mountings should be checked for security.
• Units are not portable and are only for permanent installation.
THE UNITS ARE DELIVERED WITH 0.35 BAR HOLDING CHARGE (N2) WHICH SHOULD BE SAFELY RELEASED THROUGH THE SCHRAEDER VALVE
ON THE SUCTION HEADER BEFORE REMOVING THE BRAZED HEADER / MANIFOLD CAPS.
• If the holding charge is not present the manufacturer should be contacted immediately.
• Units that have been packed in cardboard must be stored in a dry environment to prevent any water damage.
DAMAGE CAUSED BY INCORRECT INSTALLATION / UNIT MIS-HANDLING WILL INVALIDATE THE MANUFACTURERS WARRANTY
TEV SELECTION
It is important that the TEV is correctly sized and, for maximum performance, located within 100 mm of the distributor inlet. The TEV size should be determined
from manufacturer’s data using the maximum operational capacity and the minimum TEV pressure drop.
Externally equalised TEV must be used.
The minimum TEV pressure drop is the minimum condensing pressure minus the evaporator pressure and the distributor assembly pressure drop.
If the TEV is undersized or the condensing heat pressure fall below the minimum selected the evaporator pressure will drop causing ice build-up on the
evaporator coil.

ELECTRICAL INSTALLATION
TERMINAL BOX
Each unit is tted with a terminal box (es), tted on the right hand side when looking at the air discharge. Refrigeration connections are at the opposite end to
terminal box. Access to terminal box is via the unit end cover secured with four screws.
All eld wiring should be Copper and correctly sizes for the name plate current. Cable entry should be via knockouts provided and protected with a bush or
grommet.
Unit electrical schematic is secured to the inside of the terminal box or end cover.
MOTORS
All motors are EC (elec tronically commutated) and wired to the terminal box. Wires are xed to a screw or ‘cage clamp’ terminal strip.
DEFROST HEATERS
Defrost heaters, when tted, are stainless steel outer sheath terminated with a sealed black cable at the cold end. Depending on the model defrost heater will
the straight (linked pair) or ‘U’ shape. Heater are either secured to the inner drain tray or mounted in the evaporator coil and locked with a spring or retaining
clamp to prevent heater creep.
Heater withdrawal is via the connection end and requires a minimum 609mm clearance on KEC and 1219mm on UKME.
CLEANING - DANGER
Water or foam spray should not be directly sprayed at the motors or terminal box. Moisture ingress can result in failure or electrical short circuit.
CONTROL BOX
Remote control boxes (not supplied) should be located outside the cold room. Connecting wire should be adequately protected and sealed to prevent moisture
ingress.
