of the product.
3-1 Check points before operation
Before trial run, check the following points:
- Installed Conditions:
By visual inspection check that the product is level.
Make sure the product is fixed down with anchor bolts.
Do not place heavy objects on the top of the product.
Ensure the piping does not apply load to the unit.
- Power cord, and the ground should be connected firmly.
- Drain tube should be connected correctly.
- Make sure the piping for compressed air is connected correctly.
- Make sure the ball valve located next to the auto drain opened.
3-2
Operation
Start operation according to the procedure below.
- Turn on the breaker of the main power supply. Then, turn ON the Switch with lamp.
- The lamp will light up. Few minutes later, the cooling fan will rotate and hot air will be exhausted from the
ventilation grille.
Location of the ventilation grille: Right Side
- Open the IN/OUT side valve slowly. Make sure the bypass valve is completely closed. Confirm there are
no air leaks.
- Depending on the condition of compressed air or ambient temperature, the cooling fan sometimes
alternates between start/stop at the beginning. Then, the refrigerant compressor will start and the
pointer of the evaporating temperature will indicate in the green zone. If the pointer indicates higher than
the green zone, refer to
“Chapter 5 Troubleshooting.”
- After running for a while, moisture will be discharging from the drain tube automatically.
Caution
Avoid frequent On/Off operation, which may cause problems.
The auto drain used for the product has a structure that closes the valve with air
pressure higher than 0.15MPa. Therefore, until the pressure increase, air will be emitting
from the drain outlet at the start of opening the
“IN” valve. Keep in mind that sometimes
the pressure cannot increase due to under-sized air compressor.
Avoid using this product under the condition which has sudden pressure/flow rate
changes. Otherwise, drain (condensed water) may flow out to the secondary piping.
