BIDDER’S RESPONSE:
SCOPE OF WORK
The Contractor must purchase and install material. The
Contractor must refer to the manufacturer’s installation
instructions. All equipment shall be installed per
suggested manufacturer instructions. All demolished and
discarded equipment shall be removed from the
premises.
The Contractor must purchase the following:
Sand disposal units for disposing of hazardous sand.
2 (two) 10 ft cube dumpsters to dispose of hazardous
sand.
3(three) Controllers Chemtrol PC6000 Intergrated
Controller (or equal)
530 bags of Silica Sand 50#CDC
10 (ten) Solenoid valves – PVC 2”inch diameter by 10
inches long (Spark or equal). All laterals need to be
replaced. The Contractor is responsible for replacing the
appropriate lateral in each filter. The small tank which
belongs to the Splash pad may have different lateral size.
The Contractor is responsible for replacing the 8 manway
gaskets and 8 Drain port assembly gaskets.

SWIMMING POOL WATER CHEMISTRY AND
FILTRATION CONTROL
AN INTEGRATED POOL AUTOMATION SYSTEM shall be supplied for
continuous monitoring of water chemistry (ORP, PPM and pH), temperature,
Total Dissolved Solids, Langelier Saturation Index, flow rate, influent and
effluent pressures and for automatic control of the chemical feeders, bleed
and fill valves, heater, main recirculation pump and filter backwash. The
controller shall include a programmable microprocessor with an eight (8)-line
display screen and a sixteen (16)-key keyboard for operator access.
The system shall be a CHEMTROL® PC6000 INTEGRATED CONTROLLER
(or equal) of current design and model manufactured by
SANTA BARBARA CONTROL SYSTEMS of Santa Barbara, California or a
technically equal system certified by the specifying agent as capable of
providing equal performance for all operating functions.
WATER CHEMISTRY CONTROL
1. The controller shall automatically activate the appropriate chemical
feeders in order to maintain the sanitizer level within +/-0. Parts per
million (PPM) or +/- 10 mV (millivolts) of Oxidation-Reduction
Potential (ORP) and the pH within +/- 0.1 pH unit of the set points
selected by the operator. ORP and Sanitizer functions shall include
seven-day, level-based chemical saver programs. All set point and
calibration levels shall be adjustable with a numeric keypad
mounted on the front panel of the unit. Controllers with internal
switches or calibration adjustments will not be considered equal.
2.
The controller shall be capable of actuating all outputs in the
following operator-selectable modes: off, manual, automatic and
timer cycle. In the automatic mode, the operator shall be able to
choose between on/off control with adjustable dead band or
proportional feed control with adjustable dead band and progressive
control zones.
3.
The controller shall include a programmable seven-day shock
program with operator selectable ON and OFF times for each day of
the week and optional separate chemical feeder relay control.
4.
The controller shall include automatic control of a chemical feeder
for Automated Chloramine Treatment (A.C.T.)
5.
The controller shall have the capability to operate an Ozone
generator utilizing an internal spare relay with high ORP lockout.
6.
The controller shall include an electronic temperature sensor and
automatic control of the heater with a seven-day energy saver
program.
7.
The controller shall include a conductivity sensor for control of TDS
in parts per millions or conductivity in microSiemens/cm. It shall
automatically control a water dump valve for automatic purging of
saturated water, or injection of a saline solution for use with salt
chlorine generators.
8.
The controller shall continuously calculate and display the Langelier
Saturation Index using either sensor data and/or manual input for
pH, temperature, total alkalinity and calcium hardness. The water
saturation condition shall be displayed on the main screen as either
"Scaling", "Corrosive" or "OK".
9.
The controller shall be contained in a NEMA Type 4X (rain and
splash proof) lockable fiberglass cabinet with an LCD graphic
display screen of eight (8) lines of twenty two (22) alphanumeric
characters. The main screen shall display current readings, control
modes and operational status for ORP, PPM, pH, temperature, flow
rate, influent and effluent pressures. A 16-key touch pad shall be
provided for direct access to all the menus and submenus and for
entering numerical data. Controllers with smaller displays or
displays that require scrolling through menus will not be considered
equal. All screens shall have the capability of being displayed at any
time in unabbreviated English, French or Spanish and in US or
metric units.
10. The sensor bypass line shall be equipped with an in-line filter, a
flowmeter, a safety flow switch and a sampling spigot. The ORP and
pH sensors shall be mounted in a see-through flow cell with a clear
cover located inside a lockable fiberglass enclosure with a window.
The Temperature and TDS sensors will be mounted on corner Tee
in line with flow cell.
11. The controller shall be factory set to water treatment industry
standards. The operator shall be able at any time to adjust all
programmable functions to preferred settings. The controller shall
have a reset mode to reset all or selected functions to the original
factory standards.

Installation and Operating Instructions for PARA-Pump
Booster System (PBS) (Or Equal).
The PBS is a device that is used to increase the pressure
of clean filtered water from a filter system or a supply
source (non-filtered). For the purpose of supplying
consistent usable pressure for the actuation of the filter
systems backwash valves.
The PBS is designed to operate during the filter systems
backwash cycle only. A pre-set pressure switch allows
the PBS to operate on a “as needed” basis. Upon
initiation of a backwash cycle the PBS is activated
manually (by way of an on/off switch, supplied by others)
or automatically with Stark Automatic Controller (A 24
VAC N/O Relay is required, supplied by others).
PBS Components:
1. ½ HP pump and motor, 115/230 VAC, 1 phase, 60
cycle. The pump is factory wired for 115VAC
operation with pressure switch factory calibrated
for 35 psi shut-off for intermittent operation.
2. Hydro pneumatic tank
3. Check Valve Assembly
4. Tee assembly
5. 100 feet of 3/8” tubing and all necessary tubing
fittings for connection to the filter system.
6. Anchoring Hardware (3/8” x 2-1/2” lag bolts, 3/8”
flat washers and anchor shields, Qty: 2 each).
Solenoid valves:
Series 205T
The series 205T valves are available as standard 2-way
normally closed, normally open or hydraulic operated.
Is a diaphragm type valve constructed of chemical resistant
PVC plastic. Designed to operate at pressures from 10-125 psi.
with an optimum flow range of 3 to
35 GPM. An external manual bleed is offered. The slow close
feature prevents water hammer. Available
