Water Treatment

The use of untreated or improperly
treated water in the unit may result in
the formation of scale, algae, or slime.
It may also cause erosion or corrosion.
It is recommended that a qualified
water treatment specialist provide
recommendations for proper water
treatment. The Trane Company
assumes no responsibility for
equipment failure caused by the use of
untreated or improperly treated water.
Oil Separator Level
Check
Follow the steps listed below and refer
to the notes listed in Figure 60.

2. Attach the hoses and sight glass to
the oil separator charging Schrader

It is advisable to use Schrader
quickcoupler isolation valves at the
ends of the hoses. These will aid in
the installation and removal of the
hoses and minimize oil and
refrigerant spray.
3. After the unit has been off for 10
minutes, move the sight glass up
and down until the level can be seen.
4. After the level has been determined,
remove the sight glass and hoses.
Note: Routine changing of the oil or
the oil filter is not recommended. The
oil filter is oversized for this application
and should not require replacement.
The oil and filter should be replaced
only if analysis reveals that the oil is
contaminated. Oil type and system
capacities are shown in Table 1.
