ThermaHeat™ manufactures Heater Pads for the winter convenience of today’s
RV’er. The Model SL-ST725 works efficiently up to 40 gallon holding tanks and
steps. The step/tank heater pads are thermostatically controlled, designed to
turn on at 45° F (5° C) and to turn off at 67° F (20° C).
Apply ThermaHeat™ step/tank heater pads to smooth and clean surfaces. When
installing on tanks: identify the lowest point on the holding tank, closest to
the drain. Clean the surface of the holding tank with isopropyl alcohol and
let dry. Peel back the paper from the adhesive, and then press firmly and
smoothly over the intended placement area. When installing on steps: clean the
surface of the step with isopropyl alcohol and let dry. Peel back the paper
from the adhesive, and then press firmly and smoothly over the intended
placement area. DO NOT STRETCH THE PAD.
The SL-ST725 requires 13.5 V DC to operate at maximum efficiency. Please
ensure the connection to the proper voltage and the proper “on — off” switch
is used. The connection must be fused with the correct amperage. If two or
more tank heater pads are to be used they must be connected in parallel.
Please ensure after installation the lead wires are securely located and will
not hang below the surface of the tank.
