Installing
Thermoswitch
(BA–310 Only)
The Bird BA–310 requires a control thermoswitch, P/N 2450-085, for
automatic operation. It is normally open, closing at 155 °C (311 °F),
with a rating of 10A @ 120Vac and 5A @ 230Vac.
To install the thermoswitch on the load, proceed as follows:
1. Replace the vent plug in the load with the shipping plug.
2. Stand the load on its back with the connector end up. In this
position there is no danger of the coolant pouring out through the
socket plug hole.
3. Remove the top socket plug using a 9 ⁄
16
" hex wrench.
4. Replace the plug with the thermoswitch. Sparingly apply pipe
sealing compound to the external threads, only, of the
thermoswitch. Do not contaminate the coolant with pipe sealant.
5. Check for coolant leaks upon completion.
WARNING
Disconnect the unit from all power sources before servicing.
The unit may be energized from multiple sources.
The potential for electric shock exists.
WARNING
The vent plug must be used at all times when the load is
operating or cooling. Failure to do so could result in an
explosion or severe burns.
