REFILL COOLANT
NOTICE
Heater damage
: When mixing coolant, only use deionized
or distilled water and low-silicate antifreeze. Refer to your
engine’s manufacturer recommendations. Do not exceed
60% antifreeze to 40% water ratio.
Never
add unmixed
water and antifreeze to an engine. Do not add anti-leak or
other coolant additives.
11.
Mix coolant according to your engine manufacturer’s
recommendations. Refill cooling system with coolant.
NOTE:
Hotstart recommends using a 50% deionized
or distilled water to 50% low-silicate
antifreeze mixture.
12.
Start engine. Allow engine to run until engine
thermostat opens, purging air from cooling system.
NOTICE!
Engine must be run to eliminate air from
heating system before energizing heater.
13.
When engine has reached operating temperature,
shut engine off and check for coolant leaks.
14.
Allow engine to cool. Check coolant level and top off
as needed.
WIRE HEATER
15.
Connect heater to an appropriately rated power source.
NOTICE!
Terminations in all enclosures require that
wire be rated at a minimum of 60 °C. Selected wire
must be sized in accordance with heater amperage.
16.
Connect user-supplied 24 V DC control signal wire
(typically to ignition system).
NOTICE!
The heating
system must be activated only while the engine is not in
operation. To enable automatic shutdown, the heating
system requires a connected 24 V DC signal.
