- These General Delivery and Warranty Terms and Conditions pertain to the fulfillment of the contract, or sale of the products specified in the contract, and the conditions under which the terms of the contractual agreement are to be met.
The following terms are to be understood as follows:
- Seller refers to the purchase contract seller
- Buyer refers to the purchase contract buyer
- Product refers to the goods sold in the purchase contract.
- The Seller will supply products of type and quantity to match the description of the goods outlined in the contract.
- The Seller will use quality materials and workmanship in the manufacture of the product.
- The Seller will dispatch the product in a state that is suited to the use outlined in the contract and to the standard uses of such a product, including those not expressly stated in the contract.
- Unless otherwise stated in the contract, the warranty period for service work (in contracts for work) is set at 6 months, and the warranty period for products (in contracts for products) is set at 24 months from receipt.
- All claims regarding defects in the product must be immediately submitted to the Seller in written format. Upon receipt of the written warranty claim, the Seller will assess the validity of such and a decision will be made if the claim is to be accepted, or for any reason, is to be rejected. The warranty period will be automatically extended for the period of time during which any warranty repair takes place. If specifically requested by the buyer, the Seller will issue a certificate of warranty repair and extension of the warranty period. In all cases, a record of warranty repairs will be kept by the seller. All issues regarding liability for such defects in work or product will be determined by the warranty period and the terms and conditions outlined below.
- Products that are equipped with a metal retort or a belt conveyor are given warranty for the period of 6 months from the date of commissioning, or maximum of 9 months from the date of delivery.
- The place of service is the buyer's place of business, unless otherwise agreed.
- If warranty repair is required that cannot be done in the buyer's place of business, the seller will arrange and cover the full cost of transport. It is necessary to have written agreement and confirmation of the method of transport before shipping. Any costs associated with the transport of the buyer's representative to the point of repair without the prior written agreement of the seller will not be compensated.
- All costs connected with the warranty repair (including materials, service technician, and the technician's travel costs, room and board) will be covered by the seller.
- The buyer is required to have the seller handle all repair claims. If the buyer has an unauthorised third party do any repairs or maintenance during the warranty period, the buyer loses all claim to compensation for any costs associated with the defect. If anyone other that the seller's authorised service personnel does any work or repairs on the product within the warranty period, the buyer loses all rights accorded him by the warranty and the warranty will be considered invalid.
- Only the seller's authorised service contractor is authorised to do any work on the product's construction, electrical or regulatory system. In the case of violation of this point, the buyer will lose all rights accorded him by the warranty and the warranty will be considered invalid.
- It is not permitted to use the product for any other use or technology, or in any other manner than the one for which it was intended without the express written permission of the seller. Violation of this point will lead to the loss of all rights accorded to the buyer by the warranty and the warranty will be considered invalid.
- Standardly the furnaces are designed to operate with an air in the furnace chamber. The contractor points out that aggressive chemicals have a negative effect on lining, insulation and furnace equipment. These are the main substances:
- Oxidising and corrosive compounds (eg acids such as HCl / HF and acid gases such as SO2 / SO3)
- Alkali metals (Na, Li, K), their salts, oxides and hydroxides
- Phosphoric acid and phosphates
- Toxic and otherwise hazardous gases (eg Cl2, F, H2S)
If the customer is aware that the substances may be released from the batch or that such batch is processed in a targeted manner, the customer is obliged to inform the contractor of this fact already at the request stage. If the contractor is not aware of this fact within the framework of the request, he can not be held responsible for any damage to the furnace or the buyer's property, including security risks.
- The buyer is responsible for ensuring that the room in which the product is installed meets the following operating conditions complying with the definition of HD 60364-5-51:
Ambient temperature, relative humidity AB5 (from +5 °C to +40 °C, 5 %-80 %)
Altitude above sea level AC1 (£ 2000m)
Water presence AD1 (negligible)
Corrosive substance presence AF1 (negligible)
Mechanical stress AG1 (none)
Vibrations AH1 (slight)
Zero contact BC4 (permanent)
Operator skill BA4 (instructed persons)
The buyer is responsible for ensuring the initial verification of the power supply to the equipment supplied.
- Non-warranty service is billed according to the seller's standard price list. An estimated service cost quotation will be issued on request.
- The contractor confirms the temperature for controlled areas fulfills the following norms EN 746-1 and EN ISO 13732. There may be elevated surface temperature in parts that do not need to be touched, especially around the door, flaps, and other inlet and outlet openings. The requirements of the customer over and above the thermal requirements for contact with hot surfaces laid down in EN 746-1 and EN ISO 13732-1 must be governed by a contractual relationship between the customer and the contractor. The customer further states that he controls the general physical principles of heat transfer and is aware that the temperature distribution is completely different at temperature rise than maintaining the temperature at a constant value, and also depends on distribution of burning aids and charge, charge type, charge amount, shape of the required temperature curve, technical condition, network voltage and other influences.
- In the case of unjustified warranty claims, the seller will be compensated for all costs related to the processing of the claim (i.e. service technicians' working time, materials, kilometers and travel time, etc.).
- In the case that a trial firing is agreed upon as part of the purchase contract, the buyer will supply the test charge at his own cost and prepare the charge strictly according to the directions given by the seller. The seller takes no responsibility for any damage to the test charge during a test firing.
- When changing out a crucible, it is recommended to also change out damaged concrete slabs and the crucible base at the same time.
- The warranty does not cover:
- silicon door sealing and gaskets
- heating elements, considered consumable material
- crucibles, and crucible bases for furnaces
- protective iron collar for melting furnaces, considered consumable material
- concrete or ceramic plates for the furnace, considered consumable material
- crucible side supports for tilting melting furnaces, considered consumable material
- protective metal floor plates, considered consumable material
- so-called hairline cracks in the brick furnace lining which are a standard feature and do not affect the functionality of the furnace
- sectional deformations up to several millimeters (up to 30 mm according to furnace type and size) caused by thermal expansion in the steel circulatory plates and muffles do not have any influence on the functionality and operation of the product.
This also applies to the metal retort.
- gaps between the isoblock thermal insulation that can sometimes occur after furnace commissioning and that can be filled in using the spare insulation that is delivered with the furnace.
- consumable materials and parts and wear and tear occurring in the standard operation of the product
- defects resulting from the buyer's incorrect or inappropriate handling of the product or improper manipulation
- defects caused by electrical mains deviations or power failure
- defects caused by a natural disaster or other force majeure events
- defects caused by failure to heed or respect installation, service and/or operating instructions for the product
- damage to the product resulting from use for a purpose or technology other the intended
- damage resulting from failure to heed work or safety regulations
- damage (especially to the insulation or heating elements) caused by release of aggressive substances see point 14.
- Likewise, the seller is not responsible for:
- damage to or defects in the buyer's produced or heat-treated charge
- damage to the health or property of the operator or other persons
- damage or loss of profits due to product failure and repair, maintenance during the warranty period assuming the seller has not done anything to breach the contractual relationship and after the warranty period has expired
- accessories to the product which are not considered a part of the product as a whole unless otherwise so specified in the purchase contract.
- If not agreed otherwise, the furnace working space is considered to be the space where its width, height and depth is always 80 % of the furnace dimensions of inner space. There must be a gap of 10 % but not less than 100 mm between the working space and furnace interior.
- The colour design of the furnace in standard is RAL 3020 (red) and RAL 9005 (black).
