Dry Contact Operation
External relays or switches can be used with the dry
contacts if a Zodiac controller is not connected to the
RS-485 line. By creating a circuit that runs between the
dry contact, the external switch/relay, and the common
on the dry contact, when the circuit is closed the pump
will turn on, prime, and go to a pre-determined speed
indefinitely until the short is broken.
If no inputs are jumped to common, the RPM is zero.
When any Zodiac controller is connected through RS-
485, all dry contact commands will be ignored. Refer to
Figures 10 and 11 for dry contact wiring. Refer to table 4
for dry contact speed settings.
3.6.1
Dry Contact Speed Settings
Dry contact speeds settings were adjusted with motor
serial numbers beginning with the letter B.
1.
Please refer to the motor rating label to find the
motor serial number. Example is shown in Fig. 12.
2.
Refer to table 4 to determine the dry contact speeds
for the motor.

Conduct Pressure Test
IMPORTANT:
VSSHP220DV2A and VSSHP-
270DV2A come with an additional disposable o-ring for
pressure testing. This is the blue pressure test o-ring (See
Figures 13 and 14). If you opened the pump lid before
conducting the pressure test, the blue o-ring may fall out.
If the blue o-ring falls out, it must be re-installed on the
lid before beginning the pressure test (See 3.6.2).

Installation & Operation Manual
When pressure testing a system with water, air is often
trapped in the system during the filling process. This air
will compress when the system is pressurized. Should the
system fail, this trapped air can propel debris at a high
speed and cause injury. Every effort to remove trapped air
must be taken, including opening the valve on the filter and
loosening the pump basket lid while filling the pump.
Trapped air in the system can cause the filter lid to be
blown off, which can result in death, serious injury, or
property damage. Be sure all air is properly purged out of
the system before operating. DO NOT USE COMPRESSED
AIR TO PRESSURE TEST OR CHECK FOR LEAKS.
ELECTRICAL SHOCK HAZARD
Do not pressure test above 35 PSI. Pressure testing
must be done by a trained pool professional. Circulation
equipment that is not tested properly might fail, which could
result in severe injury or property damage.
When pressure testing the system with water, it is very
important to make sure that the pump basket lid is
completely secure.
1.
Before pressurizing the system, ensure the lock
ring "locked" indicators align with the suction and
pressure side ports on the pump.
2.
Fill the system with water to eliminate trapped air.
3.
Pressurize the system with water to no more than
35 PSI.
4.
Close the valve to seal the water in the system.
5.
Observe the system for any leaks or pressure decay.
6.
If there are lid leaks, repeat this procedure. For
Zodiac Technical Support, call 800.822.7933
Do not open the pump lid before pressure testing as the
blue pressure test o-ring may fall out. If this happens, you
will need to place it back on the lid.
