Step 2) The controller will only notify you when there is a failure

mode whereby the solenoid module (and connected solenoid valve)

will be activated. On the BWS5 system, the solenoid module will be

activated (shutting off the flow of water) upon LAMP FAILURE (see

Fig. 5). To remedy this, replace the UV lamp and restart the system as

per the directions outlined in the Owner's Manual.

Step 3) On the BWS6 system where a UV sensor is installed, the solenoid

module will be activated (shutting off the flow of water) upon a LOW

UV condition (less than 50%) (see Fig. 6). To remedy this, you will need

to address the reason for this low UV condition which may be due to a

dirty UV sensor and quartz sleeve, a lamp that is not emitting enough

UV energy, or a change in the water quality. Please refer to the UV

systems Owner's Manual for corrective action procedures.

Step 4) To determine what position the solenoid valve is currently in, the solenoid module

incorporates three lights on the circuit board (see Fig. 7). When the solenoid is in the OPEN

position a green light will appear on the circuit board beside the word "OPEN". When the valve

is CLOSED, a red light will appear on the circuit board beside the word "CLOSED". And when the

solenoid is in an OVERRIDE position, an amber light will appear on the circuit board beside the

word "OVERRIDE ON".

Boil Water Advisory: If any failure occurs on a BLAKE UV system, the water

must not be used for human consumption until the system is returned to a safe operational

mode. If the water is used for human consumption during this period, the water must be

boiled (minimum 20 minutes at a full boil) prior to consumption.

EMERGENCY BYPASS

In a case where the solenoid valve has been activated (valve is closed and no water is allowed

to flow), the solenoid module has the ability to bypass the solenoid valve in case of an

emergency need of water. To initiate this bypass, depress the button labeled "OVERRIDE"

located in the lower left portion of the circuit board (see Fig. 8)
