starts, stops, or during continued operation. The piping on most systems will expand and contract
with temperature changes and these changes in lengths will pass directly to the pump as applied
torque, possibly damaging the wet end if a pump saver is not used.
Pump- The pumps used in CHC systems are centrifugal pumps that may consist of a single stage
or multiple stages depending upon the requirements of the system. Pumps are normally identified
by being horizontal or vertical in construction, its HP (horse power rating) and size of its impeller.
These identifications are used to determine the exact GPM (gallon per minute) flow rate and head
pressure. Most pumps if they are leaking can be reworked in the field. Identify the type of pump
kit needed and request the kit from EcoWater CHC before proceeding to the customer site.
Purchases- A customer who decides to purchase our system will be responsible for all installation
costs as well as the cost of the system. All of our systems are warranted against defects in parts for
a period of one year and labor for 90 days. During the first year after installation, EcoWater CHC
will support the system by completing maintenance visits to check up on the system’s operation.
Purge Valve- The purge valve is an actuated valve that is placed on the drain line of a centrifugal
separator. It is opened to purge any solids out of the separator. Normally CHC systems cycle this
actuator on for 18 seconds at least once every 8 hours. Also known as a blow down valve.
Quarterly Maintenance- The quarterly maintenance is a more extensive service that is conducted
once a quarter and consists of the standard maintenance, but includes a more detailed operational
verification, system verification, and maintenance. During the quarterly Maintenance, the motor’s
amperage should be read and compared to the motor’s rating. You should also grease the motor
with the required lubricant. And clean and paint any rusty CHC system surfaces. And review the
condition of the towers. The customer will receive a copy of the Customer Service Report for their
records. This service will only be conducted by a qualified EcoWater CHC Service personnel with
few exceptions.
Relay- a relay is an automated switch that when a control signal is present to its coil, it will
energize and close the contacts found within the relay allowing power to pass through the contacts.
When specifying a replacement for a relay, you must specify the control voltage, number of
contacts and any other information shown on the relay itself.
Roof Types- There are many roof types from tin, to rubber, to concrete, to composite, to what ever
you might find. You need to understand what type of roof the customer has so you can design an
appropriate mounting system. If the customer has a rubber roof, EcoWater CHC utilizes PHP type
feet to mount the equipment directly onto the roof. Refer to
www.PHP.com for further information
on these pedestal feet. Other surfaces may require the use of a platform to support the CHC skids.
Routine Maintenance - Routine Maintenance consists of verifying the operation of a CHC system,
basic care and water analysis. Bacteria testing via a Dip Strip Test is conducted during a Routine
Maintenance visit. The customer is given a copy of the Customer Service Report that details the
findings of the maintenance. The Routine Maintenance can be conducted by a qualified
Manufacturing Representative if available. The customer will receive a copy of the Customer
Service Report for their records. This service will only be conducted by qualified EcoWater CHC
Service personnel who have been trained on the function of the system with few exceptions.
