Compressor Oil Level
The oil level in the compressor should be checked daily. The refrigeration system should never need oil
unless the system is leaking or has been recently repaired. If it is determined that the system needs oil,
do the following:
• Run the dryer for a minimum of 2 minutes, if there is not a visible level of oil in the sight glass,
proceed to the next step, if there is DO NOT add oil to the system.
• Using the appropriate oil pump add the proper oil (POE for R404 refrigerant) using the Schrader
valve on the suction side of the compressor.
• Add oil until there is a visible level in the sight glass with the compressor running.
Section 10.0 – DRAIN SETTING & OPERATION
The drain can be actuated in one of three ways. First, when power is applied to the timer, the timer will
immediately put power to the valve for the amount of time indicated by the “On Time” dial. Removing
and reapplying power will again actuate the timing cycle.
Second, pushing the test button will actuate the valve for as long as the button is pressed.
Third, once the timer is plugged in, the timing cycle will begin. The valve will be actuated at the interval
of time that is indicated by the setting of the knob for the off time.
To set:
1. Fully drain the dryer by opening an auxiliary gate valve, or push the test button on the timer.
2. When all the condensate has drained, set the off time to the maximum 60 minute setting and
the on time to the maximum 15 second setting.
4. Return prior to the time the drain is expected to open and check to see how long
long it takes for the valve to exhaust the liquid. If at the end of the drain opened period,
all the liquid has not been expelled, shorten the off time cycle and repeat steps 3, 4 and 5.
5. The drain should be checked periodically to ensure a proper setting was achieved. In
climates with large changes in humidity, the drain should be checked and reset accordingly.
