Polyethylene Water-Oil Separator

57.500 - 60 SCFM

Before Getting Started

57.500 is a single-use product.
It should be replaced as directed to ensure its vital environmental and legally protective functions are performed correctly.
The 57.500 water/oil separator is designed to clean condensates from a compressor operating at less than 60 CFM (1.7 m³/min) and less than 10 ppm oil-water, making it suitable for discharge into a sanitary drain.

NOTE : This is generally well below the accepted level, but it is the users responsibility to ensure compliance with local regulations.

Make sure you have the correct fittings for your unit before installation.

Grey ports : Compatible with imperial sizes

Black ports : Compatible with metric sizes

Installation

	1.Fix the wall plate vertically on a suitable wall or the compressor cabinet. Isolate the compressor and look out for cables and pipes when drilling.		2. Slide the 57.500 onto the wall plate, ensuring that the vent flute is at the top.
	3. Connect all drain points, insert tube into push fitting in the inlet (top). 1/4” tube for imperial 6 mm tube for metric		4.Connect tube into outlet fitting and feed to drain (side). Ensure a steady fall from outlet point to drain with no kinks or tight bends. 3/8” tube for imperial 10 mm tube for metric

Important

Always use an automatic drain. Set timers to short open periods of one second or less. NEVER use manual drains which could flood the separator, forcing partially treated or untreated condensate to be discharged.

Maintenance

Replacement

1.Ensure the condensate drain(s) are switched “OFF”. Disconnect inlet and outlet tubes from their quick fittings.

2. Lift the 57.500 from the wall plate.

4. Insert transit plug into outlet (this comes with each kit). Please note this is designed
to create a tight seal and cannot be removed once inserted.

Service Indicator Assembly and Attachment

Insert the button on the back of the bracket (c) into the pre-drilled hole of the separator cover.
Peel off the backing of the time strip (a) and attach it to the plastic card (b) between the dotted lines.
Bend or Flex the card, passing the ends through the slots on the upper surface of the bracket (c).

S57_57.502-manuels-instructions_FR-EN_2025-03_figure00

To activate, firmly press the Timestrip label at the indicated point.
After a few minutes, a red line will appear, indicating “service time” for up to 12 months.
A replacement card and time strip is provided with each maintenance kit.

Installation

Ensure a consistent downward slope in the pipe between the outlet point and the sanitary drain.
When using a timed solenoid drain, set the drain opening duration to a minimum (1-2 seconds).
When used with a motorized ball valve or high-capacity drain, a depressurization chamber must be installed between the drain and the TOPRING unit.
Never discharge condensate into a stormwater system or surface water; always connect to a sanitary drain or sewer.
Remember, it is the user’s responsibility to check with local authorities for permitted discharges in their area.
