Programming Variable Speed Operation - GRE VSG75 Instruction Manual

2. CLOSE VALVES in intake and outlet pipes if part of the pump installation.
3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner's
manual for more detail.
PRIMING PUMP
CAUTION – All suction and discharge valves MUST be OPEN, as well as filter air relief valve (if available) on filter,
when starting the circulating pump system. Failure to do so could result in severe injury.
• Release all pressure from filter, pump, and piping system. See filter owner's manual.
• If water source is higher than the pump as is normal with Above Ground installations, pump will prime itself
when suction and outlet valves are opened.
• If water source is lower than the pump as is normal with In Ground installations, unscrew and remove strainer
cover; fill strainer housing with water.
• Clean and lubricate strainer cover O-ring with high quality O-ring lubricant each time it is removed.
• Inspect O-ring and re-install on strainer cover and replace it if damaged.
• Replace strainer cover on strainer housing; turn clockwise to tighten cover.
• NOTE - Tighten strainer cover by hand only (no wrenches).
Turn on power and wait for pump to prime, which may take up to five (5) minutes. Priming time will depend on
vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within five minutes,
stop motor and determine cause. Be sure all suction and discharge valves are open when pump is running. See
Troubleshooting Guide.
ATTENTION – Wait five (5) seconds before re-starting pump. Failure to do so may cause reverse rotation of mo-
tor and consequent serious pump damage. Close filter manual air relief valve after pump is primed.
5. PROGRAMING VARIABLE TIME & SPEED FUNCTIONS:
Follow the programming setps in this section carefully. Take your time so you complete the programming suc-
cessfully the first time. It is helpful to have a second person to read the programming steps from the manual as
you enter the values with the operation buttons.
OPERATING MODES
These pumps have two operationg modes: Manual and Automatic. You can switch back and forth for your
preferred operating mode. To switch between modes, press the "UP" and "DOWN" buttons at the same time.
1.0 - MANUAL OPERATING MODE:
(Image #1)
In Manual Mode the pump runs at the constant speed set by the user. (See Image #1)
1.1 - Manual mode has 4 default speeds : "LOW", "MEDI", "HIGH" and "FULL"
LOW MEDI HIGH FULL
Speed 1.150 1.700 2.100 2.850
