water supplied too hot, reduce temperature.
2. If after fill phase, faulty HTR or SSR1 – replace.
(Refer to Figure 5-5.)

5.1.12 UV Lamp Problem
Description - SYSTEM 1E Processor detects a UV
intensity of less than 14.5mA.
Action:
1. Fouled (dirty) quartz sleeve – clean.
2. UV monitor harness not connected – plug into

5.1.13 MaxPure™ Filter Test Failed (a. without
and b. with numbers)
Description – a. (without numbers) The housing of the
MaxPure Filter is pressurized. The pressure must reach
>55 psi in three minutes or the alarm occurs. If this
portion passes, the housing pressure is maintained for
three minutes. After this three-minute stabilization
period, the pressure must be >52.83 psi or the alarm
occurs. If this portion passes the control waits
15 seconds and checks the housing of the MaxPure
Filter pressure again. The pressure must be >51.73 psi
and <58.75 psi or the alarm occurs.
Action:
1. Air leak – repair.
2. Faulty COMP1 – replace. (Refer to Figure 5-5.)
3. PT1 out of calibration – recalibrate.
4. PT1 – replace. (Refer to Figures 5-1 and 5-2.)
5. Faulty FLT1 – replace.
6. Faulty CK4 – replace.
7. Faulty CK6 – replace.
8. Faulty housing of the MaxPure Filter – repair or
replace.
9. Faulty CK11 – replace.
Description – b. (with numbers) A two-minute hold
test is performed. The pressure in the housing of the
MaxPure Filter is monitored for two minutes. During
this two-minute hold period, if the pressure drop
exceeds 4.4 psi, an alarm occurs. Three numbers are
printed; start pressure, finish pressure and the elapsed
time of the failure (seconds). Pressure prints are in psi.
Action:
1. Faulty FLT1– replace and rerun test.
2. Air leak – repair.
3. Faulty SOL8 – replace. (Refer to Figure 5-5.)
4. Faulty housing of the MaxPure Filter – replace.
5. PT1 out of calibration – recalibrate.
6. Faulty PT1 – replace. (Refer to Figures 5-1 and 5-2.)
7. Faulty CK11 – replace.
5.1.14 Temperature Problem
Description – Sensor on control board sees
temperature < 13°C or > 65°C.
Action:
1. Correct room temperature if out of specification.
2. Replace control board if room temperature OK.
