GENERAL SAFETY INFORMATION RECEIVING, MOVING, AND UNPACKING 1. PRESSURIZED DEVICES: A. RECEIVING This equipment is a pressure containing device. • Do not exceed maximum operating pressure as shown on equipment serial number tag. • Make sure equipment is depressurized before working on or disassembling it for service. This shipment has been thoroughly checked, packed and inspected before leaving our plant. It was received in good condition by the carrier and was so acknowledged.

D. Standard units are designed to operate in ambients: Air-cooled: 45 to 110°F (7 to 43°C). Water-cooled: 45 to 130°F (7 to 54°C). IMPORTANT: READ PRIOR TO STARTING THIS EQUIPMENT 1.0 INSTALLATION 1.1 Location E. A. For typical placement in a compressed air system, see drawing. B. Air compressor intake–Locate air compressor so that contaminants potentially harmful to the dryer (e.g. ammonia) are not drawn into the air system. C.

1.2 Mounting 1.6 Electronic Demand Drain Mount on floor or shelf free from vibration. Installation 1.3 Piping connections 1. A. Air Inlet—Connect compressed air line from air source to air inlet. 2. 3. 4. Refer to Serial Number Tag for maximum working pressure. Do not exceed dryer’s Maximum Working Pressure. NOTE: Install dryer in air system at highest pressure possible (e.g. before pressure reducing valves). NOTE: Install dryer at coolest compressed air temperature possible.

For Sales & Service Call: 705-722-5747 Ext.1 2.2 Start-up A. Energize dryer. Green power on light will illuminate. IMPORTANT: Energize dryer disconnect switch 24 hours before refrigeration compressor is started! Never use the disconnect switch to shut-down the dryer for an extended period of time (except for repair). Failure to follow these instructions may result in a non-warrantable compressor failure. B. 1. 2. Program monitor.

D. Operating check points 1. Check that green Power-on light is illuminated 2. Check that green Compressor-on light is illuminated if dryer is on in the manual mode or it is a scheduled on time IMPORTANT: Refrigeration compressor must be restarted after power interruption. 3. Check interface panel NOTE: Interface panel will switch between Current Time/ Operating Status screen and Hours to Service/Total Operating Hours (HRS TO SVC/TOTAL) screen.

Dryer Driven Mode- the contacts will be energized and de-energized in parallel with the refrigeration compressor of the dryer. Therefore, if the refrigerationcompressor is on, the contacts are energized; if the refrigeration compressor is off (manually or by a system fault condition), the contacts will be deenergized. NOTE: It is the responsibility of the end-user to properly design the system control circuitry when using the auxiliary contact feature. To select Schedule Driven or Dryer Driven modes: 1.

TROUBLESHOOTING GUIDE SYMPTOM A) Water downstream of dryer B) High pressure drop across dryer C) Checkpoint faults 1. Power on/off light 2. Compressor on light off 3. Alarm/Service alert light on check Display for active conditions SERVICE DRYER POSSIBLE CAUSE(S) 1. Residual free moisture remaining in downstream pipelines 2. Air by-pass system is open 3. Inlet and Outlet connections are reversed 4. Air lines downstream of dryer are exposed to temperatures below the dew point. 5.
