Step-by-Step Installation Guide

Step 1: Verify Spa Compatibility

Before installation, ensure your Sundance spa falls within the 400-1,000 gallon capacity range. Check your spa's specifications:

• Standard Sundance Models: Confirm your model number matches unit specifications
• Water Capacity: Verify gallon capacity falls within 400-1,000 gallons
• Filtration System: Ensure proper filter operation for optimal mineral distribution
• Sanitizer Type: PoolRx works with chlorine, bromine, and salt systems

Step 2: Prepare Your Spa

Proper preparation ensures optimal performance:

1. Drain and Clean: Start with a fresh water fill if possible
2. Clean Filter: Ensure spa filter is clean and functioning properly
3. Check Equipment: Verify pump, heater, and circulation systems are operational
4. Test Existing Water: If not draining, test current water chemistry
5. Remove Old Treatment: If switching systems, ensure previous treatment is removed

Step 3: Install the PoolRx Unit

The installation process is straightforward:

1. Remove Unit from Packaging: Carefully unpack the PoolRx unit
2. Locate Filter Compartment: Access your spa's filter area
3. Place in Filter Canister: Drop the unit directly into the filter canister
4. Alternative Placement: If filter placement isn't possible, place in skimmer basket or directly in spa near return jet
5. Ensure Water Flow: Position so water flows through or around the unit
6. Secure if Necessary: Use provided attachment if needed to prevent movement

Avoid common maintenance mistakes during installation.

Step 4: Initial System Start-Up

Once installed, activate the system:

1. Run Circulation System: Turn on spa pump to circulate water
2. Monitor for 24 Hours: Allow initial mineral release period
3. Check Water Flow: Ensure proper circulation through filter system
4. Initial Chemical Adjustment: Add minimal sanitizer as directed
5. Temperature Consideration: Higher spa temperatures may accelerate initial mineral release

Initial Setup and Chemical Balancing

Water Chemistry Preparation

For optimal PoolRx performance, establish proper water balance:

• pH Level: Adjust to 7.2-7.6 before adding unit
• Total Alkalinity: Maintain 80-120 ppm for stability
• Calcium Hardness: Keep at 150-250 ppm for plaster spas
• Initial Sanitizer: Add chlorine or bromine to recommended level (1-3 ppm chlorine, 3-5 ppm bromine)
• Water Temperature: Note that higher temperatures increase chemical reactions

Reduced Chemical Protocol

With PoolRx installed, adjust your chemical routine:

• Chlorine Reduction: Reduce chlorine usage by 50-80% from manufacturer recommendations
• Testing Frequency: Test sanitizer levels 2-3 times weekly initially
• Shock Treatment: Shock only when needed, not on regular schedule
• Oxidizer Use: Use non-chlorine oxidizer weekly for organic breakdown
• Mineral Monitoring: Note water clarity and user comfort as indicators

First Week Adjustment Period

The initial week establishes system effectiveness:

1. Days 1-2: Monitor water clarity and adjust filtration as needed
2. Days 3-4: Test sanitizer levels and adjust minimally
3. Days 5-7: Observe bather comfort and water quality
4. Week 2 Onward: Establish reduced chemical maintenance routine

Ongoing Maintenance and Monitoring

Weekly Maintenance Tasks

• Test Sanitizer Levels: Check chlorine/bromine 2-3 times weekly
• Monitor pH: Test and adjust pH as needed to maintain 7.2-7.6
• Check Water Clarity: Visually inspect for sparkle and transparency
• Clean Filter: Rinse or clean filter weekly depending on usage
• Surface Skimming: Remove debris from water surface
• Waterline Cleaning: Wipe waterline to prevent buildup
• Cover Maintenance: Clean and condition spa cover regularly

Monthly Maintenance Tasks

• Deep Filter Cleaning: Thoroughly clean or replace filter cartridge
• Test Total Alkalinity: Check and adjust if outside 80-120 ppm range
• Check Calcium Hardness: Test and adjust as needed
• Inspect PoolRx Unit: Check mineral unit for proper placement and condition
• System Flush: Consider flushing circulation lines if needed
• Equipment Check: Inspect pump, heater, and control systems

Seasonal Considerations

• High Usage Periods: Increase testing frequency during heavy use
• Temperature Changes: Adjust chemical dosing with seasonal temperature variations
• Vacation Periods: Set spa to maintenance mode when away
• Winter Operation: Maintain regular schedule if spa is used year-round
• Seasonal Opening/Closing: Follow proper procedures for seasonal operation

Water Testing Protocol

Essential Testing Parameters

With PoolRx, focus on these key water quality indicators:

• Free Sanitizer: Chlorine 0.5-1.5 ppm or Bromine 2-4 ppm (reduced levels)
• pH Level: 7.2-7.6 (critical for mineral effectiveness)
• Total Alkalinity: 80-120 ppm (stabilizes pH)
• Water Clarity: Visual assessment of sparkle and transparency
• User Comfort: Monitor for skin and eye irritation
• Odor: Check for chemical or musty smells

Testing Frequency Guidelines

• Daily During Initial Week: Test sanitizer and pH
• Weekly Established Use: Test sanitizer 2-3 times, pH weekly
• After Heavy Use: Test following multiple users or extended soaking
• After Adding Water: Test following water addition or replacement
• When Issues Arise: Test immediately if water appears cloudy or odors develop

Interpreting Test Results

Understanding what your tests indicate:

• Low Sanitizer: Add minimal amount to reach 0.5-1.5 ppm chlorine or 2-4 ppm bromine
• High pH: Use pH decreaser to reach 7.2-7.6 range
• Cloudy Water: May indicate need for oxidizer or filter cleaning
• Eye Irritation: Usually indicates pH imbalance, not sanitizer level
• Musty Odor: Suggests need for shock treatment or increased circulation

Troubleshooting Common Issues
