Haws Corporation Tempered Water Nevada USA, Singapore: Care and Repair

Here at Haws we are frequently asked if there are any periodic maintenance tips that we can offer for installed products. All Emergency Equipment is required to be activated weekly by ANSI. Purging the standing water out of the lines reduces buildup of stagnate water and helps remove rust from pipes in galvanized units.

In addition, purging helps guarantee that the water supply has not been inadvertently turned off, that there are not any missing or broken parts and most importantly that the units are working properly. Eyewash maintenance is especially important. In most units there is a SP509 inline screen strainer between the eyewash valve and bowl that must be periodically cleaned. The strainer cap must be removed by a 3/8” hex wrench and the screen can then be accessed and cleaned. During the weekly testing it is also crucial to check pathways leading to the unit to make sure there are not any obstructions that would hinder the access and use of the unit.

Drinking Fountains from 2003 to now have a front access 5874 push button valve which has a screen strainer under the cartridge that should be periodically cleaned depending on site conditions. In order to clean the strainer, water must be shut off to the unit and using the spanner wrench that comes with the unit, remove the push button, the inside ring nut and cartridge. The gasket screen should come out with the cartridge and should be cleaned thoroughly.

Water coolers also need periodic cleaning. The fan blows air over the condenser fins, so the condenser should be vacuumed every 6 months to remove lint and dust that builds up (cleaning may be need to occur more often if the unit is in a dirty environment). This is crucial to the proper functioning of the unit, because lint and dirt buildup causes the unit to overheat due to the restricted air flow. This overheating can lead to shortening the life of the unit, and even to damaging the compressor.

For all products it is important to rinse and wipe off the unit regularly to prevent dirt build-up that could potentially hinder the effectiveness of the unit.

Fraud Labs Pro Fraud Detection and Fraud Detection Solutions: How is the sequence of execution of fraud validation rules?

FraudLabs Pro allows user to configure multiple fraud validation rules with multiple actions, such as Approve, Manual Review, and Reject. But, how is the sequence of execution if I had configured multiple validation rules with different actions? Below are the explanations of the execution logic.

FraudLabs Pro adopts an easy-to-understand sequential checking for the validation rules. It basically checks the validation rules starting from the 1st rule to the last one in the sequence. If the system found the match during the sequential check, it will stop the checking process and flag the transaction based on the action defined. However, if the system completed the sequential check with no match found, it will flag the transaction as Approve. It’s as simple as explained. Below is the summary of the validation logic:

  • If match found during the sequential check, stop the checking process and flag the transaction based on the action defined, such as Approve, Manual Reviewor Reject.
  • If sequential check completed with no match found, flag the transaction as Approve.

Example of validation scenarios.

Example of the fraud validation rules

Assuming you created 3 validation rules for Free Email, Email in Blacklist and Anonymous Proxy as above. (Note: to ease the explanation, this tutorial will not display the exact rule name but a short representation)

Scenario 1: User’s email address is a yahoo email.

The validation process will be stopped at Rule #1 and the transaction will be flagged as Manual Review.

Scenario 2: User’s email address is a company email but had been previously blacklisted by FraudLabs Pro.

Rule #1 pass the validation. However, the validation process will be stopped at Rule #2 and the transaction will be flagged as Reject.

Scenario 3: User’s email address is a company email with clean record, and not using Anonymous Proxy.

The validation process completed successfully and the transaction will be flagged as Approve.
