How to Winterize Your Ionic Window Cleaning Systems: A Complete Guide for Cleaning Business Owners

Posted by Gisela Moreira Bozeli on Nov 05, 2024

Winter can be a challenging season for cleaning businesses that rely on specialized equipment like Ionic window cleaning systems. For those operating in colder climates, where service demand drops during winter, preparing your system for storage is essential. Alternatively, some business owners may choose to run their systems periodically to avoid full winterization. In this guide, we’ll explore both approaches so you can make the right decision for your business.

Why Is Winterization Critical?

If water remains inside your system during freezing conditions, it can cause damage by expanding in filters, membranes, and pumps. Neglecting to winterize can lead to costly repairs, system downtime, or even the need for complete replacements. Taking preventative action ensures your equipment is ready to function properly when the busy season resumes.

Option 1

Full Winterization Process

If your Ionic system will remain idle throughout the winter, follow these steps to prevent freeze damage and maintain the efficiency of your machine.

1. Drain and Dry the Pumps

Run the 12v Pumps Until Dry
Completely drain the water tank, and switch on the 12v pumps to pump out any remaining water. Let the pumps run until no more water comes through, ensuring the system is free of residual moisture that could freeze and damage internal components.

2. Replace the Sediment Filter

Remove and Discard the Filter Element
Sediment filters trap organic debris that can degrade over time. Remove the element and retain the spacer at the top for future use. Install a new filter when you resume operations.
Annual Filter Change
Use the winter downtime to replace the sediment filter, keeping your system in top shape for spring.

3. Dispose of the Carbon Filter

Prevent Organic Matter Buildup
Carbon filters capture organic material, which can break down and contaminate the system. Remove and discard the used filter before storage, and install a fresh cartridge before your first job in the spring.
Maintenance Tip
Plan to replace the carbon filter every 1,000 hours of use or annually—whichever comes first.

4. Flush and Seal the RO Membrane

The reverse osmosis (RO) membrane requires special care during storage.

Flushing and Storage
1. Remove the RO membrane housing and flush it with pure water for 10 minutes.
2. Seal the housing by fitting blanks into the John Guest (JG) fittings to keep the membrane submerged in pure water.
3. Store the membrane housing vertically to prevent damage.
Avoid Freezing Conditions
Store the RO membrane in a controlled environment, as freezing temperatures can cause irreversible damage.
Preparation for Spring
When it’s time to resume work, remove the blanks, drain the housing, and flush with pure water for 3 minutes.

5. Store the DI Filter with Care

Remove the Snap Ring for Ventilation
If your DI filter is still in good condition, leave it installed but remove the snap ring for ventilation. This step helps prevent internal pressure buildup during storage.
Keep the System Above Freezing Temperatures
Like the RO membrane, the DI filter must be stored in a temperature-controlled area to prevent freezing.

Option 2

Running the System Periodically to Avoid Winterization

For cleaning businesses that want to skip the full winterization process, there is an alternative—running your Ionic system periodically throughout the winter.

Run the System Once or Twice a Month
Operating the system at least once or twice per month keeps the pumps, membranes, and filters active, preventing water from stagnating or damaging components.
Temperature Precautions
Make sure the system is only run when temperatures are above freezing. If there’s a risk of freezing, delay operation until the weather improves.
When to Choose This Option
This approach is ideal if your business operates in a region with mild winters or if you anticipate using the system occasionally during the season. However, regular monitoring is essential to avoid accidental freeze damage.

💡Additional Tips

If your business continues to operate in cold weather, follow these recommendations to protect your system:

Use Insulation and Heaters
Insulate your machine’s tanks, hoses, and pumps to prevent freezing. Portable heaters can help maintain functionality in extreme cold.
Non-Toxic Antifreeze
In freezing conditions, some operators add non-toxic antifreeze to their systems. Always consult your system's manual or manufacturer to confirm compatibility.
Monitor Battery Health
If your system has battery-powered components, disconnect the battery during downtime and store it in a cool, dry place. Recharge periodically to maintain capacity.

Planning for Spring Startup

Before resuming operations in the spring, conduct a test run to ensure everything functions smoothly. This includes flushing the filters, reconnecting hoses, and running the pumps to verify performance. Identifying issues early allows for timely repairs and avoids unexpected downtime during peak seasons.

Winterizing your Ionic window cleaning system—or periodically running it during winter—ensures that your business is prepared to hit the ground running when demand returns. Proper care during the off-season protects your investment, reduces maintenance costs, and ensures consistent performance year-round.

Whether you choose to winterize fully or run the system periodically, the key is to prevent freezing and keep the components in good working order. For more expert advice on maintaining professional cleaning systems, visit clean.direct.
