LEAKING- 2.0.0 DISABLE THE DEAERATION PUMP (PRIMARY SIDE LEAK?)
Turn the machine off. Dry the leak site and allow 30 seconds. Does the leak remain active?
Yes See procedure number
No See procedure number
LEAKING- 2.0.1 PRIMARY SIDE LEAK
Read the list below (not inclusive) and proceed accordingly:
Leak from heat exchanger #77 tubing: 1) Check Inlet Water Pressure Regulator per Calibration
Procedures (18 – 20 psi); 2) Check tie wraps or replace tubing
Leak from heat exchanger #77 seal or screws: 1) Assure incoming water pressure is no greater than
105 psi; 2) Check Inlet Water Pressure Regulator per Calibration Procedures (18 – 20 psi); 3) Repair or
replace the heat exchanger
Leak from valve #39 (mounted on the bottom of the hydro block or hydro chamber): 1) Check
tubing connection; 2) Tie wrap or replace tubing; 3) Check o-ring; 4) The valve body may be leaking
Leak at reinforced tubing attached to hydro block/ hydro chamber: Tie wrap or replace the tubing.
Leak between regulator #61 and valve #41 (not including the heat exchanger): 1) Assure incoming
water pressure is not exceeding 105 psi; 2) Check Inlet Water Pressure Regulator per Calibration
Procedures (18 – 20 psi); 3) If 1 and 2 are okay, check tubing connections tie wraps or replace tubing; 4)
If valve #41 is leaking check the tubing connection, o-ring, or the valve body may be leaking
LEAKING- 2.0.2 PRIMARY SIDE LEAK
Read the list below (not inclusive) and proceed accordingly:
Leak from heat exchanger #77 tubing: Check tie wraps or replace tubing
Leak from heat exchanger #77 seal or screws: Repair or replace the heat exchanger
Leak from the acid and/or bicarbonate pump reinforced tubing. Tubing may be 'blowing' off: Tie
wrap or replace the tubing
Leak from RINSE PORT tubing connections (inside the machine): Check tubing connections tie
wraps or replace the tubing
'Spraying' from either RINSE PORT: The internal, spring loaded, poppet valve is not sealing. Insert a
dull probe and press the valve back and forth a few times to clear possible debris (possibly from a
concentrate connector o-ring)*. If spraying continues, replace the port. *Recurring debris see procedure
number LEAKING- 4.0.0
Leak between the deaeration pump #20 and the hydro chamber (including the mixing chambers
#82): Check tubing connection tie wraps or replace the tubing
Referring to Figure 105
Leak is between the BOTTOM BALANCING CHAMBER VALVES, #35 and #37 and the hydro
chamber: 1) Check tubing connections and tie wraps
be leaking
Leak is between the TOP BALANCING CHAMBER (BC) VALVES #32 and #34 and DRAIN
VALVE #30: 1) Check tubing connections and tie wrap or replace the tubing; 2) Possible bad o-ring
seal on BC valves 3) The valve body may be leaking
