ENGLISH
Refrigerants
R22, R134A, Propane, Butane, R500 and R502.
If the moisture indicator is removed the MLI can alternatively be used as a normal sight glass, for R717 (ammonia) also.
Installation
The MLI may be installed anywhere in the liquid line. If the Main liquid line is larger than 40 mm (1½”) we recommend the MLI to be installed in by-pass (Fig. 1).
Welding / Soldering
MLI must be disassembled during welding/ soldering (Fig. 2).
Assembling
Remove dirt and weld slag, if any, from tubes and housing.
Lubricate the seal face (Fig. 3) before the indicator element is mounted and tightend (Fig. 4).
Colour
From factory the MLI-housing is painted in a reddish brown primer.
Indicator element
When received the indicator may not indicate dry. This phenomenon does not affect operation or calibration of the
indicator due to the fact that action of the indicator element is completely reversible. As a result the indicator element will change colour whenever the moisture content of the system changes.
Time of colour change might differ from plant to plant. We recommend that the plant operates for at least 12 hours to
allow the system to reach equilibrium before deciding if the drier should be changed.
The drying of the system should be continued until the indicator element stays dark green (Table 1).
Do not pressure test the MLI by means of water, too much water is liable to damage the indicator.
The indicator element are not suitable for
R717 (ammonia).
In case of doubt please contact Danfoss A/S or distributor.
Errors and omissions excepted. Subject to change without notice.
