Deltech Fitness 8000 instruction manual Shutdown

Danger Label: Parts of Circuit May Be Energized

Part No. 58DE27A

Do not turn power switch to ON until the end of the 4-hour warm-up period. This 4-hour period is essential. It heats up the refrigerant compres- sor oil and boils off liquid refrigerant to pre- vent compressor failure. The warm-up period can be shortened or skipped only if the purifier had been operated and supply power has been interrupted for less than two hours.

3.During the warm-up period review the installation instructions to make sure the purifier is properly installed.

For all purifier models:

4.Turn the front-panel power switch to ON; allow a 4-hour warm-up period. For models 8DM75, 8DM100 and 8DM150, this warm-up period is in addition to the warm-up period required to heat the crankcase.

Do not allow air to flow through the purifier dur- ing the second warm-up period. This warm-up is essential to drive moisture out of the catalyst ves- sel. Moisture in the catalyst reduces carbon mon- oxide conversion efficiency and may result in inadequately purified air.

When the power switch is turned on, the POWER ON light will light. It is normal for the fans to cy- cle on and off or to run continuously in warm am-

bient air temperatures. It is also normal if some of the red indicating lights flash.

5.After the power switch has been on for one hour, check the control panel. The red indicating lights should signal in sequence. If any red indicating light flashes call the Deltech Product Service De- partment for instructions.

6.Supply compressed air up to the inlet valve.

7.Slowly open the inlet valve and allow the purifier to reach operating pressure. If no pressure gauge is installed in the air line, wait three minutes.

8.Slowly open the outlet valve to let purified air flow downstream.

Once this start-up procedure is complete, purifier op- eration is continuous.

Shutdown

8DM Series purifiers are designed to run continuously. Do not turn the purifier off unless maintenance is needed. Restarting the purifier involves a significant warm-up period (see Start- up).

To shut down the purifier:

1.Stop using the outlet air for breathing.

2.Close customer-supplied inlet and outlet shutoff valves.

3.Turn the power switch on the front panel to OFF.

4.Open customer-supplied depressurization valve to vent internal purifier pressure to the atmosphere.
