TEST PROGRAM
(FOR SOFTWARE VERSIONS 2.0 AND LATER)
PRELIMINARY:
To test a new installation, first check that all necessary connections for electrical,
water, gas and drain are made. Standard 3-phase electrical power supplies are
480VAC 60 HZ, 415VAC 50 HZ, or 380VAC 50 HZ.
With electrical power off, prepare to purge the gas line of debris and air by closing
off the gas supply valve before the Gas Pressure Regulator (GPR) and having the
main gas supply on. Open the pipe cap on the end of the short pipe debris trap nipple
under the regulator and quickly open/close the gas supply valve several times. Debris
in the pipe will blast out. Keep doing this until gas is noticeable. Make sure good
ventilation is present and no one is smoking.
Check that power on terminals 1 and 3 on the electrical panel is between 103 and 125
VAC.
Check the spray chamber for any packing material, debris or extra parts that may
have accumulated there. Close the 2-inch drain valve and verify that the small drain
on the bottom of the water pump is closed. Begin filling the tank with water.
Now set the air gate valve in the piping that regulates the air volume from the
Humidaire Unit’s outlet for the application. (This volume will vary depending on
whether the application is a lint slide grid, conditioning hoppers, a moisture
conditioning condenser, a Steamroller, or some combination of those devices.) When
the air volume is satisfactory, the operator will need to adjust the air shutters on the
Humidaire Unit to maintain the correct air velocity across the burner head.
