At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

Zodiac pH Perfect W500702: High-Fidelity Automatic Regulation

The Zodiac pH Perfect W500702 is an autonomous monitoring and dosing system for pH corrector. This equipment uses proportional dosing technology to maintain the chemical balance of the water continuously, optimizing the efficiency of saline disinfection.

The cost of inaction when ignoring pH instability includes eye irritation, water turbidity, and irreversible degradation of the electrolysis cell. The Zodiac pH Perfect resolves these operational risks through precise IT/OT control that stabilizes the pH at the ideal set point.

Technical Opportunity: Final Stock Clearance

The Zodiac pH Perfect W500702 is a discontinued model by the manufacturer. This unit represents one of the last opportunities to acquire original hardware compatible with existing installations that require "Plug and Play" replacement without modifying the hydraulic infrastructure.

  • Intelligent Proportional Dosing: The microprocessor adjusts injection time according to the detected deviation, avoiding chemical overdosing and abrupt oscillations.

  • Exclusive Overdosing Safety: The system includes the OFA function, which stops dosing if the set point is not reached within a specific time, protecting the pool shell.

  • Standard Compatibility: Designed to integrate with any filtration system or salt chlorinator on the market, regardless of the main equipment's brand.

  • Zodiac Electronic Robustness: Manufactured to industrial standards that ensure a long service life in corrosive technical room environments.

Technical Specifications

  • Product Reference: W500702.

  • Dosing Type: Proportional peristaltic.

  • Pump Flow Rate: 1.5 l/h.

  • Measurement Range: From 0.0 pH to 14.0 pH.

  • Protection Rating: IP65.

  • Supply Status: Discontinued model in clearance until stock runs out.

  • Power Supply: 230V AC.

Installation Protocols and Technical Compatibility

The Zodiac pH Perfect W500702 must be installed on the return circuit after the filtration system. To ensure analytical accuracy, the pH probe must be placed before the chemical injection point or the electrolysis cell.

TECHNICAL RESTRICTION: This equipment is in the Final Clearance phase. Future replacement is not guaranteed once current stock is depleted. It is recommended for technicians who need to maintain systems compatible with the W500702 platform without performing comprehensive renovations.

Frequently Asked Questions

  • Is this equipment new despite being discontinued? Yes. The Zodiac pH Perfect W500702 is a brand-new unit in its original packaging. Its "discontinued" status refers exclusively to the cessation of manufacturing by Zodiac, which allows for its acquisition at a competitive clearance price.

  • What is the warranty for a product on clearance due to end of stock? Like all technical products sold at Q-tech.es, it carries the current legal warranty. However, because it is a clearance model, in the event of an irreparable failure, an equivalent solution would be managed as there is no replacement stock from the manufacturer.

  • Can I use it to dose both pH reducer and pH increaser? The equipment comes factory-configured for dosing pH reducer (acid), which is the standard requirement in residential pools. Its software allows the control logic to be reversed to act as a pH increaser doser if the installation requires it.
