Hose Heat Power Pack
The power pack provides low-voltage electrical power to the heating element embedded
in each section of hose. The output voltage of the power pack is adjusted by changing
the tap settings of the transformer. To ensure proper functioning of the heated hoses, the
transformer tap settings must be adjusted to match the total length of hose to be used.
To connect the power pack and select the correct tap settings, proceed as follows:
1. Turn OFF and lock out incoming electrical power at the source.
2. Plug the tap wire with inline fuse (B) into the Power-Lock hose heat connector on
the end of the console wire (A).
(See Figure 4.)

3. Using Figure 5 and the chart below, connect the power lead (C) and the tap wire (B)
to the transformer taps that match the hose length to be used.
IMPORTANT: The power pack must be set to match the hose length used. Too
much power will cause the hose heat circuit fuse to open; too little power will result
in insufficient hose heating.
