Never install or remove the HYDROCAL1005 without opening first the
aeration screw.
Never use galvanized fittings or valves to mount the HYDROCAL1005
unit.
Galvanized fittings or valves can react with oil; this will produce incorrect
measuring values.
Never clean the HYDROCAL1005 unit with high pressure cleaning
equipment.
High pressure cleaning equipment used to clean transformers can seriously
damage the HYDROCAL1005 unit.
Never use a chaining key tool for mounting.
Use of such tools can damage the surface of the measuring head and the
threads. Please use an adjustable thin spanner for 1 ½“.
Attention!!!
Faulty or inappropriate handling of the sensor head like malfunction by
negative pressure, paint or solvent liquids make the warranty invalid.
