Warning: The warnings, cautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator. Unpacking When unpacking, check to make sure the parts listed on page 9 are included.
Installation (continued) Note: We recommend that a bypass valve (not included) be added between the Air Inlet (#6) and the Air Outlet (#7) for applications when the Air Dryer is not needed. The bypass valve must be installed by a plumber or an authorized service technician. See FIGURE 1.
Electrical Installation (continued) Refer to FIGURE 2 on page 5. Note: Wiring must be done by a professionally certified electrician. 1. Remove the side panel. 2. The top three wires of the electrical box are pre-wired at the factory. 3. The wires from the electrical cord (not included) must be rated for a minimum of 10-1/2 load rated amps, and the plug on the electrical cord must be three pronged (recommended 12 gauge, 3 conductor electrical cord).
Operation (continued) Note: The Air Dryer works using “Refrigerant 134A”. The refrigerant system does not need to be serviced unless the unit begins to leak. If the unit leaks refrigerant, take it to an authorized service technician. Note: Decide whether you want to use the Air Dryer or bypass the unit. Follow the instructions for using or not using the bypass valve on page 5. If you set the valves for “Using the Air Dryer”, follow the instructions below. 1.
Troubleshooting Continued Problem 7: Ice accumulating in the dryer, and/or a pressure loss through the unit. Reason: Solution: This may be caused by the formation of ice inside. The Hot Gas Bypass Valve (not shown in the Parts List or Assembly Diagram) needs to be adjusted. This adjustment should only be done after consultation with our technical support service at: 1-800-444-3353. Maintenance Note: Maintenance must be performed by an authorized service technician.
