1. Zero Energy State
NOTE: ZERO ENERGY STATE
To perform service, maintenance and repairs you must disconnect the RigMaster
from its battery source. In the recommended installation configuration the
RigMaster shares the battery bank with the vehicle's main engine.
Unplug the J1 harness at the power module before disconnecting the battery
cables. After disconnecting the battery cables, check the battery posts inside the
RigMaster engine cabinet to confirm there is no voltage to the auxiliary power
unit (APU).
2. Safety Cover Switch
WARNING!: SAFETY COVER SWITCH
It is critical that this safety cover switch is never bypassed; failure to comply may
result in serious injury.
The safety cover switch (Figure 1)
is designed to prevent the
RigMaster Power APU from starting
when the engine cover is loose or
has been removed. When the
cover is down, the switch is in the
closed position. When the cover is
open or loose, the switch is in the
open position. The switch is
located at the very top of the unit
enclosure on the surge tank
bracket.
Figure 1 –Safety Cover Switch
3. AutoStart Automatic Start/Stop Feature
CAUTION: AUTOSTART FEATURE
Remember that a properly functioning RigMaster is capable of starting
independently of its operator. If the AutoStart feature is enabled, battery voltage,
temperature, and time of day can all cause the RigMaster’s engine to start.
Please see the cabin controllers operating instructions for further information on
the AutoStart feature. You must deactivate this feature prior to refueling.

4. Engine Hoist Points
NOTE: ENGINE HOIST POINTS
The Kohler engine has hoist points that are useful for removal and reinstallation
of the engine. It is advised that these hoist points should only be used if no other
means of lifting the unit are available.
5. Starting Aids
WARNING!
Do not use any type of starting aids such as ether. Such use could result in an
explosion and personal injury, and will render the APU warranty null and void.
6. Starting with the Cover Off
CAUTION
Some installation or repair/diagnostic procedures require that the APU is started
with the engine cover off. Do not deactivate or bypass the safety cover switch.
Instead, have another individual assist by manually holding the safety cover
switch down in the closed position for the duration of the procedure.
7. Inspection of the Safety Systems
The safety systems on the RigMaster APU should be examined and tested prior
to performing any service work and at 50 hour intervals to ensure that they are in
good condition and proper working order.
8. Safe Working Practices
Safe working practices are your responsibility. The use of protective safety
equipment is mandatory when performing inspections, service, diagnostics and
repairs on the RigMaster APU. Follow your local regulations and guidelines
regarding occupational health and safety.
9. Contact Us
If you do not fully understand this safety information contact RigMaster’s
Technical Support Department toll free at (888) 208 –3101 before proceeding

Heater
NOTE
This section is only applicable to those models WITH heat.
The RigMaster heating system is fully automatic. A constant comfort zone is
maintained with the temperature selector (see Cabin Controller Operation –
Page 11). The bunk heating system is a complete stand alone system that is not
integrated into the vehicle's cooling system. When heat is selected, and the
RigMaster is in operation, the hot coolant flows through the heater core (installed
under the bunk –see Figure 2).
The heater/air conditioner blower motor (fan) circulates the cab air through the
heater core pushing warm air into the bunk area. The coolant is then re-
circulated back to the RigMaster Unit.
This system is designed to maximize the bunk heating efficiency.

Heating System
For heating, the APU’s coolant flow is directed into the HVAC box mounted
inside the bunk. A water valve mounted to the HVAC box regulates the flow of
coolant through the heater core.
Voltage at the J2 Connector Pin-1 on the power module will indicate if the water
valve is open or closed. (Closed=0 volts / Open=12.4 volts).
Figure 3 –Heating System
NOTE
Notice the coolant flow when the valve is open. The coolant will travel to the
HVAC box and then return on the opposite pipe.
Electronic Coolant Control Valve
The electronic coolant control valve motor shaft is a good indication if the valve is
opening when changing temperature modes. Marking the shaft with a black
marker which will make the shaft rotation more visible. When the valve is closed
coolant will loop back to the engine.
