MOUNTING
CAUTION
!
Lifting hazard:
Use proper lifting equipment and
rigging to move this equipment. Create a plan before
attempting to move. Heating systems with flanges have
marked lift points. When lifting, use soft straps and
avoid placing side-loads on heating system plumbing
components, including fluid pumps.
Overheating hazard:
When mounting the heating tank,
position the tank so that it is completely full of fluid while
in operation.
NOTICE
Heating system damage:
Engine vibration will
damage the heating system; isolate the heating system
from vibration. Never mount the heating system or
components directly to the engine.
Improper mounting hazard:
Reference heating
system component drawings before mounting the
system. Unless mounted properly, the heating system
will be unstable.
2.3.1 TANK AND PUMP
Mount the heater below the fluid level in the engine on
a level surface in a vertical orientation with pump motor
assembly directly above tank. Reference drawings for
mounting position.
When installing the heating system, ensure sufficient
clearance for the following components:
•
Control box
Ensure the control box is accessible and the
lid may be opened.
•
Pump motor cooling fan
Ensure the cooling fan is not obstructed.
•
Heating element
Note the tank may require up to 30 inches
(762 mm) of clearance to remove element
for maintenance. The clearance required
for specific part numbers will be shown on
system drawings.

ELECTRICAL CONNECTIONS
WARNING
!
Hazardous voltage:
Before wiring, servicing or
cleaning the heating system, turn off the power
and follow your organization’s lockout and tagout
procedure. Failure to do so could allow others to turn
on the power unexpectedly, resulting in harmful or fatal
electrical shock. Install in accordance with any applicable
local codes based on the installation location.
Electrical hazard:
The heating system must be
connected to a suitable protective earthing conductor.
The heating system’s power supply must be connected
to a suitable overcurrent limiting device. A means of
disconnection from power supply is required. Hotstart
recommends that a power switch or circuit breaker be
located near the heating system for safety and ease of
use. Reference markings on heating system for specific
ratings.
2.4.1 MAIN POWER SUPPLY
1.
Connect the specified power from the customer-
supplied circuit breaker to the terminal blocks
located in the main control box.
See Figure 6 on
following page.
NOTE:
The specified power source must be within
plus or minus 10% of the rated voltage.
NOTE:
The circuit breaker must be near the
heating system and easily accessible.
Hotstart recommends connecting the
heating system to a circuit breaker rated for
125% of the system’s maximum load.
