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.
