shared electric motor. Several different types of electric
systems are used on HEARTLAND RECREATIONAL
VEHICLES, LLC products, depending on the model.
But each is able to be operated by a hand crank in the
event of a motor or power failure.
Slide Out Circuit Breakers
If attempting to move the slide and it is perceived that
the electric motor has no power, inspect the breakers
and fuses. If a fuse is blown you may need to replace it.
Slide Out Weather Seals
Frequently check all seals and gaskets on the slide
out walls for proper fit and operation. The seals and
gaskets should be coated with a silicone spray for easier
operation and weather protection.
Inspect the condition of the slide tubes (not the hydraulic
ram) under the slide out, and if needed, use bearing
grease for ease of operation.
Although every attempt is made to have 100% air-tight
seal, you will find that the best seal possible can be
achieved with proactive maintenance and proper use.
Hydraulic Slide Out System
The hydraulic slide out system uses a 12-volt DC
power motor to drive a hydraulic pump, which moves
fluid through a system of hoses into a dual directional
hydraulic actuator to extend and retract the room(s).
Electricity for the pump motor and assembly is supplied
by the RV Battery. A simple press and release wall
mounted switch provides normal operation to extend
and retract the slide out room(s).
Typical maintenance for the pump would be to verify
and add an automotive type a fluid for the pump. The
pump has a see thru reservoir that makes checking for
proper level easy. For best performance, the fluid level
should be within ½ inch of the top of the reservoir with all
room(s) retracted (closed). It is recommended to check
the fluid level every month.
The Hydraulic pump is wired to an auto reset breaker
that is mounted within 18 inches of the RV battery. If
an electrical overload would occur, this breaker would
interrupt the operation of the slide out room temporarily.
Causes for this to occur could be a low battery, loose
or corroded battery terminals or ground wire. The slide
room may be binding (unit may not be level, sticks,
leaves, or other wedged items between the room and
the wall). The slide room and system may be out of
adjustment. Something may be blocking the extension
or retraction of the slide room.
The hydraulic system can be manually overridden in case
of failure or when electrical power is either interrupted or
not available. For proper operation, please refer to the
manufacturer’s instructions supplied with your unit.
Please refer to the manufacturer’s instructions supplied
with your unit for proper care and operation of the
