Version 2.2, 18/06/2020
2.2. UNPACKING THE GOODS
The method of packing is for products to be loaded onto crates or pallets and secured with bolts. A protective
film is added to minimize any potential water and dust ingress.
If the product is not delivered in a pallet the integral base frame of the equipment should be used for handling.
Ensure any safety bolts are unfastened before attempting to remove the equipment from the pallet otherwise
permanent damage might occur.
If the equipment was transported at temperatures below 0°C it is recommended to leave it in the operating
environment for at least 2 hours after unpacking for temperature compensation to take place.
After unpacking the equipment check whether the unit and other parts have been supplied in good condition.
All claims for damage or missing goods must be reported to Barkell immediately and confirmed in writing within
2 working days upon receipt of the goods otherwise the right to claim will be lost.
IMPORTANT: Never attempt to put a damaged ventilation unit into operation.
IMPORTANT: Small items such as controllers and sensors are packaged either together with the product
packaging or inside the product.
Do not dispose of the packaging before verifying all items have been removed from it.
Do not put the product into operation before verifying there are no loose items inside it.

2.3. HANDLING THE GOODS
Before off-loading the goods please ensure that a suitable means of transport/lifting to accommodate the
weight and size of the equipment is available.
The weight of the equipment is displayed on the manufacturing label fitted on the outside of the packaging, on
the equipment control panel door and on the documentation provided at the time of order confirmation. Please
check the weight of the unit before attempting to handle it.
For products delivered in pallets or with integral base frame the use of a fork-lift or pallet truck is recommended.
If the equipment needs to be lifted with straps it is recommended to use spreaders to avoid damage to the
casing.
Manual lifting between floor and shoulder level is acceptable only up to a maximum weight of 20kg
(89/391/CEE).
Take care when handling the equipment to ensure that damage to coil pipe work connections, spigots, drain
trays, etc. is avoided.
3. STORAGE
Should it be required to store the products on site for any period of time prior to installation they should be
stored in a clean, dry and secure area with an ambient temperature between 5°C and 35°C.
Inlet and discharge openings, pipe connections and filters should be sealed to avoid moisture ingress.
The equipment should be inspected on a regular basis and its packaging repaired if damaged.
The equipment should not be stored in areas where there is excessive vibration as this could damage fan
motor bearings.
If access panels are removed for inspection purposes or to carry out work on site they should be refitted and
made secure.
Small items delivered with the equipment such as sensors, controllers, etc… shall be stored safely from
unauthorized access, damage and the weather.
Crated or palletized horizontal mounting ceiling products (HRFL2) can be stacked on top of each other for
transport up to a maximum of 2 units high. For long term storage the maximum allowable stacking will depend
on the size of the unit, please contact our offices for more information.
Free standing units (HR85, HR95) cannot be stacked.
