Waterside
Procedures
Binder Points
Binder points should be fitted to both the flow and return pipe work adjacent to the cooling coil.
Water Strainer
A water strainer must be fitted to the inlet side of the evaporator.
Failure to do so may result in severe damage and will void the AIREDALE warranty.
Water Flow Rate
Check that the design water flow rate is available to the unit. If not available do not turn unit on.
Waterside Pressure Drop
Measure the waterside pressure drop of the unit ensuring control valves are operating satisfactory.
Glycol Strength
Check and record the glycol type and strength. Low levels of glycol can cause freeze up problems when operating at
low temperatures or during the unit off state during cold ambient conditions.
Glycol concentration is measured by use of a Refractometer.

Check pressure drop of water strainer. If
excessive clean the strainer. ●
Visually inspect pipe and pipework insulation.
Pipework clamps are secure. ●
Inspect for water leakage. ●
Check condition of Water / Glycol solution to ensure that the
system is protected against corrosion, scale and microbiological
fouling, ensuring maximum heat transfer efficiency. ●
