START UP
The following procedure must be followed to start your air dryer. Failure to follow this start up
procedure will void your warranty. If problems occur during start up, contact your distributor.
1. Turn off the On/Off switch.
2. Verify the main electrical supply voltage matches the voltage specified on the data label.
3. Check the proper connection and support of the compressed air lines to the dryer: check dryer
bypass and isolation valve system.
4. Confirm that the inlet and ambient air temperature, pressure and flow to the dryer meet the
specified requirements.
5. Confirm that the condensate drain lines from the separator are properly piped to an environ-
mentally approved disposal system
INITIAL RUN PROCEDURE
After start up and checks are complete and after the main electrical power to the dryer has been
turned on for at least 6 hours (only for 460-3-60 & 230-3-60 dryers), follow the procedure below to
put the dryer in operation:
1. Turn ON the dryer ON/OFF switch.
2. Let the dryer run for 15 minutes. (For 460-3-60 & 230-3-60 dryers After 15 seconds observe the
refrigerant suction pressure gage. It should start to pull down immediately. (This will indicate
that L1,L2,L3 is connected for proper rotation. If the pressure does not pull down switch 2 of
the L1,L2,L3 leads.)
3. Check the refrigerant suction pressure gage:
Should read: On R134a dryers. (28 psig to 34 psig)
Only: MHT75, MHT100,MHT130
4. Check the DEWPOINT TEMP INDICATOR . After about 15 minutes This should read
35 F to 39 F.
5. Verify that the condenser fan motor is operating. The fan will cycle on and off.
6. Confirm that condensate is discharging from the condensate drain. This may take 30 -60
minutes.
