- Page 4 Section 2.0 - Getting Started Before unpacking/uncrating your new dryer, inspect the carton/crate for damage. Note any damage on the freight bill. File notice of concealed damage if: there are any dents in the cabinets the air and drain pipes are not straight there is any sign of oil on the skid or floor the refrigerant gauges show NO pressure File these claims with the carrier immediately!
- Page 5 Section 3.0 – DRYER INSTALLATION NEVER work on unit under pressure NEVER work on unit when power is connected. DO NOT over pressurize unit. DO NOT pass air through the unit until it has been stabilized (operating 2 - 15 minutes). The larger the dryer, the longer it takes to stabilize. The dryer is considered stabilized when the refrigeration suction gauge reads between 28 to 35 PSI.
- Page 6 Install a bypass line and gate valve to permit isolation of the dryer from the air system. This is done to provide easy service and/or removal of the dryer without interruption of air to the system. Fig. 2 (Models 80- 300)
- Page 7 USE TWO (2) WRENCHES WHEN CONNECTING DRYER TO PIPING. THIS WILL PREVENT DAMAGE TO INTERNAL AIR LINES. Electrical Connections To be performed by a qualified person only. Risk of serious injury or death. Before connecting electrical power to the dryer check for correct voltage and phase at the connection box.

During Actual display mode, displays the dew point temperature from 20ºF to 99ºF or -6ºC to 37ºC. During DP SET mode, the unit displays dew point set points from 36ºF to 50ºF in 2º...
- Page 10 (9) Drain Control Settings. The DP5050-L series control panel will operate by either a “Level Float” or “Timed” interval. If the dryer is equipped with a Level Float (electrical connections to terminal J9), the drain will respond to the float signal on demand to operate the drain.
- Page 11 Panel C (12) High Ambient Temp Display. Should not be above 100ºF. High ambient temperature can cause head pressure tripping of refrigeration system and could result in non-warranty damage to refrigeration compressor. This display is used for water temperature in water cooled units. (13) High Inlet Temp Display.
- Page 12 Section 5.0 – Sensors, Controls and Relays Drain Relay (K1) Opens the drain valve according to drain controls. Suction Relay (K2) Turns on according to the mode and dew point conditions and opens the suction or liquid line valve when opened. Unloader Relay (K3) Turns on according to the modes and dew point and opens the unloader valve when active.
- Page 13 Section 6.0 – START UP PROCEDURE There should be NO air flow through the dryer before or during start up. It is recommended that the dryer be installed with bypass piping to better service the unit. SC/CT 80-100 1. Plug in unit. 2.
