NITE Plus ® SECTION 2 ELECTRICAL INSTALLATION...
Electrical Installation NOTE: Bergstrom does not condone putting batteries under the sleeper bunk. The floor is not designed to carry that amount of weight and even deep cycle AGM batteries can emit gas under certain circumstances. Bergstrom can only support batteries being placed in battery boxes or tool boxes designed to support the weight of the batteries outside the cab of the truck.

Checklist 2. System components checklist Follow this table to check that the individual components of the NITE Plus run properly when the unit is ON. Component Function How to check it Blower (evaporator) Blows cold air to the sleeper Switch the NITE Plus control area through the ducting.
Page 44
3.4 Condenser outlet temperature The NITE Plus unit pulls air from outside under the sleeper floor to cool down the condenser coil. The air is then expelled to the outside, also under the sleeper floor. With the NITE Plus running in HIGH, locate the condenser air outlet under sleeper—it is a rectangular opening with a screen.
Page 45
Checklist 4.3 Check voltage with engine OFF First, check that the voltage on the TRUCK batteries is the same as the voltage on the separator (use the ground terminal to check separator voltage). Both voltages should be approximately 12V. Next, check that the voltage on the aux batteries is the same as the voltage on the separator (use the ground terminal to check separator voltage).
