Attaching a Hose For External Pump-Out
The Professional Sous Vide Circulator pump features two outlets that can be fitted with a suitable hose to allow
water to be pumped out of the bath, either for external re-circulation purposes or to assist in emptying large water
baths. For most applications, only one hose should be fitted, allowing the other outlet to circulate water in the bath
to maintain temperature uniformity within the tank. If both outlets are used, temperature uniformity in the bath will
be reduced and should be considered as part of your application.
Before attaching a hose, ensure the equipment is disconnected from the mains power supply and the element is cold.
The diameter of the pump outlet fitting is 9.5mm. Use a suitable hose with an internal diameter of approximately 9 to
9.5mm to maintain a snug fit on the outlet, with an outer diameter no larger than 15mm. Silicon hose is
recommended for most applications. Simply push the hose over either outlet until it touches the guard, a hose clamp
may be used if required however this is not normally necessary if using the correct size hose.

Power
CAUTION
The equipment must only be used with a protective earth power socket. The earth contact provides protection to
the user and the equipment. If you do not have a protective earth power socket, or you are unsure as to whether
you have a protective earth power socket,
do not
connect the equipment. In such cases you should consult your
workplace administrator or electrical maintenance staff to determine if a protective earth power socket is available.
The mains power supply must be rated to match the power requirement as identified on the product identification
label on the rear panel. This is normally expressed in the format of Voltage Range and Frequency.
A surge protected
power outlet is strongly recommended as it provides some protection for the equipment in areas of poor
electrical quality as well as providing some protection against lightning strikes. The equipment should be
operated on a good, reliable supply of power at all times.
Note: The Professional Sous Vide Circulator should not be operated on the same electrical circuit as other high
voltage household appliances such as fridges, clothes dryers, washing machines or other continuous operation high
voltage devices. These types of devices can create power fluctuations that are undesirable for electrically sensitive
equipment. Consult your workplace administrator or electrical maintenance staff if you are unsure.
IMPORTANT : Use of an incorrect power supply will void the product warranty. If you are unsure about the
rating of your power supply, consult your workplace administrator or electrical maintenance staff to
determine if your power supply is suitable for use with this product before connecting the power lead.
