Care for the years
after opening.

Paid technical assistance may be available for matters outside the agreed supply scope. Responsibility for the following normally rests with the buyer, its contractors or the relevant local authority:

• Destination-market registration, importer registration, energy-labelling administration and locally required sampling or testing, except where expressly included in the agreed scope.
• Building structures, civil works, levelling, decorative finishes and waterproofing supplied or installed by other contractors. Warranty for Yuanwang-supplied and installed pool waterproofing is described separately below.
• Local electricity, water, drainage or gas infrastructure; voltage fluctuations, inadequate supply pressure, abrupt water-quality changes and utility interruptions.
• Third-party equipment independently procured or installed by the buyer, unless supplied with Yuanwang’s system.
• Installation, wiring or commissioning errors by the buyer or its contractors, including incorrect pipework, omitted flushing or departure from approved drawings.
• Unapproved alterations, dismantling, relocation, software changes, control replacement, misuse, operation beyond design conditions or missed maintenance.

Notify Yuanwang in writing before modifying equipment. A substantial modification can create new conformity-assessment responsibilities for the party making it; the applicable destination rules must be assessed for the specific change.

• Project and customer name; equipment model and serial number.
• The fault, when it began, how often it occurs and actions already attempted.
• Site photographs or video and alarm records.
• Current flow, pressure, temperature and electrical-current readings, with recent water-quality results where relevant.

Requests sent only to a salesperson’s personal WeChat, WhatsApp or private telephone are not formally registered service requests and do not start the agreed response clock. After registration, video calls may be arranged through WeChat, WhatsApp or Teams as appropriate.

• Video inspection, an agreed site evidence checklist and transfer of operating data normally come first.
• Remote control-system access requires the customer’s written permission, a temporary access route and closure of that route after the session.
• Yuanwang can provide technical guidance and parts to a local provider. A written service authorisation defines the work; the provider acts for the customer and cannot make warranty commitments on Yuanwang’s behalf.
• Unless otherwise agreed, the customer contracts with and pays the local provider directly.

Normally the warranty begins on signed commissioning and acceptance at the destination site, after the fifth commissioning checkpoint. If acceptance is delayed by the customer for more than 30 days, the warranty start date moves to the date the equipment arrived on site. This arrangement must be reflected in the project contract.

• Installation, operation or maintenance contrary to the manuals, including omitted flushing, missed backwashing and incorrect electrical connections.
• Water outside the design water-quality schedule attached to the contract, including damaging scaling, corrosion, iron, manganese, sulphur or chloride conditions.
• Overdue maintenance. Where the agreed warranty incorporates this condition, failure to complete required annual maintenance reduces the original warranty period by half.
• Human damage, misuse, unapproved modifications and operation outside the approved conditions.
• Force-majeure events such as earthquake, flood, extreme freezing, lightning, war or epidemic restrictions.
• Normal wear and natural changes in appearance.

Keep dated maintenance and water-quality records so that the cause and applicable cover can be established.

The standard proposal includes one on-site training session lasting 2–3 business days for the customer’s operations and maintenance staff. It covers daily operation, backwashing, dosing, setpoints and common fault diagnosis. A signed training record identifies attendees and topics completed.

Electronic English operation and maintenance manuals are provided, with diagrams for key procedures. Follow-up video training or training in China may be arranged at an agreed cost.

Yuanwang supplies Chinese originals and an English version. Required destination-language translations, their accuracy and cost must be allocated in the contract. English alone may not satisfy destination requirements; this allocation does not displace statutory manufacturer or importer duties.

For machinery covered by Regulation (EU) 2023/1230 when it applies, digital instructions must be downloadable, printable and accessible for the required period. Paper instructions requested at purchase must be supplied free within one month; essential safety information for non-professional users must be supplied on paper. Apply the rules in force when the specific product is placed on the market.

Yuanwang or an authorised service provider prepares a report covering annual operating trends, efficiency change against the first-year baseline, component-life estimates, replacement recommendations and next-year maintenance or upgrade priorities.

The report gives owners a documented condition review that may support operational, insurance or financing discussions. The scope and any third-party acceptance requirements should be agreed separately.

• Create a well record at handover: depth, diameter, aquifer, initial water level, temperature, yield, sand content and mineralisation.
• Define acceptance at an agreed operating point, including yield, temperature and drawdown. Record the actual values rather than leaving these conditions unspecified.
• Compare annual results with the initial baseline. A 15% decline in yield triggers a diagnostic review of screen blockage, scaling, pump wear and regional groundwater changes.
• Assess well-pump replacement after approximately 5–8 years according to condition and duty. Qualified personnel must carry out the work; Yuanwang can assist with selection and supervision.
• Consider online level, temperature and flow monitoring, with an agreed route for returning the data for early assessment.

• Circulation-pump mechanical seals: 2 sets for each installed model.
• Filter-system O-rings and differential-pressure gauges.
• Dosing-pump diaphragms and non-return valves.
• Heat-exchanger gaskets: 1 set for each model.
• Critical control-cabinet relays and fuses.
• Underwater lights: 2 spares of the same model.

First orders normally use full prepayment; terms for established customers can be agreed. Report packaging or visible damage within 48 hours. Under this policy, absence of such a report is treated as confirmation of external condition; it does not by itself determine a latent-defect claim.

Record which legal entity is the importer of record. Possible arrangements are the buyer or its local company; an EU authorised representative for specified manufacturer duties together with the buyer as importer; or an agreed local partner under a separate three-party arrangement.

An authorised representative is not automatically the importer. Each role retains its legal duties. Relevant importer checks can include conformity assessment, marking and accompanying documents, destination-language instructions, traceability and cooperation with market-surveillance authorities. Required document-retention periods must be recorded.

The current policy assumes project-specific arrangements; it does not claim that Yuanwang already operates a European service organisation.

CE marking is the manufacturer’s indication that the applicable requirements have been met. It is not a blanket third-party approval; some product categories require notified-body involvement. Confirm the correct assessment route, declaration, technical records, markings and manuals for each model.

Pump energy-efficiency obligations depend on product scope and the rules in force. Confirm current ecodesign applicability for the particular pump rather than treating a general swimming-pool-pump exemption as a performance claim.

Great Britain means England, Scotland and Wales. Official guidance provides for continued recognition of CE marking for relevant regulated product groups, including machinery, alongside UKCA. Check the specific product route and current GB requirements before placing equipment on the market, especially around changes to EU machinery rules.

Northern Ireland follows a distinct route under the Windsor Framework. CE is used where applicable; CE with UKNI is relevant where a UK body performs mandatory third-party assessment. UKNI is not a standalone mark and UKCA alone is not accepted for EU market access.

• Commercial invoice, packing list and bill of lading or air waybill.
• Applicable conformity declaration identifying legislation, standards, model and authorised signatory; the required technical file is retained and made available to authorities as required.
• Original instructions and any required translations, clearly identified as such where applicable.
• Nameplate verification: manufacturer details, model, serial number, manufacturing year and required conformity markings.
• Compliant solid-wood packaging / ISPM 15 treatment evidence where applicable.
• Export and inspection documents matched to the actual HS code and current regulatory requirements. Confirm any statutory inspection before booking shipment.

Responsibility is assessed in the following order:

1. Contract and attachments, including design duty, water-quality conditions and acceptance criteria.
2. The five installation and commissioning checkpoint records.
3. Operating and maintenance logs.
4. Examination of the failed part and any independent test report.
5. Relevant industry practice and original manufacturer standards.

This policy proposes notice within 30 days after discovering, or being expected to discover, a defect. This is a proposed contractual notification period, not a fixed deadline imposed by CISG Article 39. Where the CISG applies, Article 39 uses a reasonable-time requirement and generally a two-year outer limit from actual handover, subject to the contractual guarantee period and applicable exceptions.

Yuanwang’s response follows the priority table above. The target for a written responsibility assessment is 30 business days after complete claim materials are received.

Official CISG text and resources ↗

The recommended contract arrangement is a project aggregate liability cap equal to the contract value and exclusion of indirect loss, lost profit, business interruption and third-party claims, except for deliberate misconduct, gross negligence and personal injury. These are proposed B2B contract terms; they apply only as agreed and to the extent legally enforceable.

The proposed governing law is the law of the People’s Republic of China, excluding Hong Kong, Macao and Taiwan for this choice of law. The proposed forum is CIETAC arbitration in Beijing, with Chinese and/or English as agreed. Confirm governing law, seat, institution and language when signing; undisputed obligations continue during a dispute.

• Services and spare parts normally use agreed prepayment. Allow for cross-border payment processing and intermediary charges; allow approximately 3–7 business days, with actual timing dependent on banks.
• USD or EUR pricing is suggested. Specify who bears exchange-rate movements and which rate is used.
• Destination duties and VAT normally fall to the buyer / importer, except under an agreed DDP allocation. Quotations should state whether destination taxes are excluded.
• For an on-site visit, the suggested arrangement is a 50% advance against estimated travel expenses, followed by settlement against actual agreed costs.

Relevant events can include war, civil disorder, terrorism, government restrictions, natural disasters, epidemic or quarantine restrictions, visa refusals or entry restrictions, shipping disruption, port strikes, export controls, sanctions, embargoes and destination-law changes preventing lawful supply.

The suggested contract arrangement provides for written notice and supporting evidence within 15 days; the parties then agree a revised plan. If the event continues for more than 6 months, either party may terminate the unperformed portion, with completed work settled on an actual basis. Any relief depends on the signed terms and applicable law.
