Procedures
Binder Points
Binder points should be tted to both the ow and return pipe work adjacent to the evaporator.
Water Strainer
A water strainer must be tted 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 ow 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 that the pump (if tted) is operating.
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. Check pipework clamps are
secure
●
Inspect for water leakage ●
Check pressure drop of evaporator. If excessive clean evaporator ●
Check condition of Water/Glycol solution to ensure that the system is protected
against corrosion, scale and microbiological fouling, ensuring maximum heat
transfer efciency
