Q1: How to select an appropriate installation location for an ultra-pure water machine before installation?

A1:

• Keep away from vibration sources: Avoid placing the machine near vibrating equipment such as centrifuges and air compressors to prevent damage to precision components.
• Ventilated and dry environment: The ambient humidity should be < 80% to prevent circuit dampness or microbial growth.
• Avoid high temperature/direct sunlight: The recommended ambient temperature is 10-30℃; high temperature will accelerate pipeline aging.
• Reserve maintenance space: Leave a gap of at least 30cm at the back of the equipment to facilitate filter element replacement and maintenance.

Q2: How to correctly connect the water inlet pipeline? What are the key points to avoid problems?

A2:

Water source requirements:

• Municipal tap water (with TDS < 200 ppm) must be used; direct connection to lake water/well water is prohibited.
• The water pressure should be stable between 0.1-0.4 MPa; a booster pump must be installed if the pressure is insufficient.

Pipeline problem - avoiding points:

• Use food-grade PE pipes to prevent plasticizers from leaching out of ordinary hoses.
• Install a Y-type filter (with 100 mesh or above) at the water inlet to block large-particle impurities.
• It is strictly forbidden to connect hot water pipelines to the equipment (the RO membrane can withstand a temperature < 45℃).

Q3: What are the precautions for the installation of the drain pipe?

A3:

• Drain outlet height: The end of the drain pipe must be higher than the floor drain (to prevent siphon backflow pollution).
• Anti-backflow design:
  • Install an Air Gap to prevent sewage backflow.
  • It is forbidden to insert the drain pipe directly into the sewer; a gap of more than 2cm should be reserved.
• Slope requirement: The drain pipe should maintain a slope of 1-3° to prevent water accumulation and bacterial growth.

Q4: How to optimize the layout of the pure water delivery pipeline?

A4:

Material selection:

• PTFE (polytetrafluoroethylene) pipelines are preferred to avoid organic matter leaching from PVC pipes.
• For long-distance transportation (> 5 meters), a circulating pipeline system is recommended.

Layout principles:

• Minimize the length of the pipeline to reduce "dead water areas" (where microorganisms are prone to multiply).
• Avoid right-angle bends in the pipeline; use large - radius elbows (> 120°) to reduce flow resistance.

Q5: Which environmental factors are "invisible pitfalls"?

A5:

Electrical safety:

• The machine must be grounded to prevent static electricity from damaging sensitive components (such as the TOC detection module).
• Avoid sharing sockets with high - power equipment; it is recommended to configure a UPS voltage - stabilizing power supply.

Chemical pollution risks:

• Keep away from volatile reagents (such as formaldehyde and hydrochloric acid) to prevent corrosion of the equipment shell.
• It is not advisable to install the machine near the laboratory fume hood, as air flow disturbance will affect its stability.

Q6: What key checks are required for the first startup?

A6:

Three - level confirmation:

• Water circuit: Check that all interfaces are free of leakage and the drainage is smooth.
• Circuit: The voltage is stable (220V ± 10%) and the ground wire resistance is < 4Ω.
• Air circuit: There are no air bubbles in the system (air can be exhausted through the vent valve).

First flushing:

• Do not connect the terminal filter; flush continuously for more than 2 hours to drain the protective solution completely.
• Test the initial product water resistivity; it can be used only when the resistivity is confirmed to be > 10 MΩ·cm.

Q7: How to verify whether the system operates normally after installation?

A7:

Performance test:

• Product water flow rate: Compare with the nominal value in the manual (e.g., 1.5L/min).
• Water quality test: Resistivity (18.2 MΩ·cm) and TOC (< 5 ppb).

Stability observation:

• Operate continuously for 24 hours and check for abnormal noise/alarm.
• Compare the water quality data in the morning and evening; the fluctuation should be < 5%.
