Sieve Bed Removal
To remove sieve beds, follow the steps below:
1. Set the unit’s I/ 0 switch to the “0” position and disconnect the power cord.
2. Remove the side and back panels.
3. Cut the tie-wrap and disconnect green tubing at each elbow fitting located
on the top of the sieve beds.
4. Remove the 9/16-inch compression fitting from the bottom of each sieve
bed.
5. Cut the tie-wraps securing the sieve beds to the superstructure and remove
the sieve beds.
Sieve Bed Installation
To install the sieve beds, follow the sieve bed removal procedure in reverse order.
Do not over tighten fittings.
To check for leaks, take the following steps:
1. Connect the unit to power, and set the unit’s I/ 0 switch to the “ I” position.
2. Allow unit to run for three minutes.
3. Apply soapy water solution around tubing connections on both sieve beds,
and check for leaks.
5.6 Cabinet Fan
The cabinet fan pulls ambient air into the NewLife Intensity unit. As this air is drawn in,
the air cools internal components (including the compressor) and exits out the bottom of
the unit.
The cabinet fan for NewLife Intensity is located in the back of the unit. Refer to the
troubleshooting chart in Section 6.0 of this manual for instances where replacement of the
fan may be required.
5.6.1 Cabinet Fan Replacement
To replace the cabinet fan, follow the steps below
1.
Set the unit’s I/ 0 switch to the “0” position and disconnect the power cord.
2. Remove the side and back panels.
3. Remove the two screws that hold the fan to the superstructure, and remove the fan.
4. Disconnect the fan leads.
5. Position the new cabinet fan so that the air flow arrow points toward the
compressor and the electrical connections are in the bottom right corner.
6. Connect the fan leads, and install the cabinet fan screws.
7. Reconnect the back and side panels.
5.7 Circuit Board
The solid-state printed circuit board controls the timing operation of the five solenoid
valves and the alarm system functions. The five-green-light matrix corresponds to the
valve configuration of the NewLife Intensity unit. Two green lights should always
illuminate and rotate (cycle) during normal operation.
A green light that fails to illuminate indicates a disconnected or faulty solenoid coil or an
electrical malfunction in that valve circuit. The two vertical red lights indicate high and
low pressure.
