Visually inspect all port connections monthly for liquid weeping, staining, or corrosion. Perform pressure test at rated working pressure annually to detect internal joint failure. Check for signs of seepage at solder joints.

Monitor return temperatures - smaller-than-specified temperature differences indicate fouling. Use SWEP's pressure drop calculation tool: 30% pressure drop increase from clean baseline indicates cleaning is needed. Compare measured vs. expected performance quarterly.

Check for excessive pulsations or cyclic pressure/temperature changes. Verify vibration isolators are installed and functioning. Inspect plates for deformation or cracking under UV/bright light. Avoid pressure spikes exceeding 10% of rated maximum.

Inspect external surfaces monthly for pitting, discoloration, or rust deposits. For All-Stainless units, verify Sealix protective layer integrity. Check fluids for metal leaching particles using optical inspection or ICP-OES testing annually.

Verify inlet/outlet flow rates match design specification (compare to pressure drop). Listen for unusual fluid noise indicating turbulence or cavitation. Perform CIP (Cleaning in Place) if flows decrease unexpectedly. Check inlet strainer condition.
