Dear Customer!
Thank you for choosing this heater! We have done everything possible to make this
product meet your requirements, while its quality satisfies the best world standards.
Introduction .
The PLANAR heaters are designed to be used:
to keep the operator cabin warm;
to provide heating for various limited volume interior spaces in vehicles;
to maintain comfortable room temperatures for a long time.
The heater operates independently of the vehicle engine. The principle of
operation is based on forcing heated air through the heat exchanger system of the
heater.
Please read these instructions carefully to learn about all the functions of the heater.
Safety Instructions .
Installation of the heater and its component parts must be
carried out by specialized organizations approved by the
manufacturer. Installation of the heater must be carried out only
by specialists in accordance with the installation instructions.
Health hazard
The heater may only be used for the purposes specified in this
manual.
Due to the risk of poisoning by exhaust fumes when the heater
is operating, the heater shall NOT be used in vehicles located in
closed and poorly ventilated premises (garages, shops, etc.).
Danger of property
damage
When refuelling the car, the heater shall be switched off.
The heater power shall not be disconnected until the end of
the purge cycle.
Any electrical connections or disconnections of the heater
shall NOT be carried out while the power is ON.
Do not step or put any items on the heater.
Do not put any garments, pieces of fabric, etc., on the heater,
nor place them in front of the intake or output of heated air.
After turning off the heater, reconnection should be made at
least after 5-10 seconds.
For safe operation of the heater, the customer service should
be contacted to identify and repair malfunction after two
consecutive failed start-ups.

Responsibility .
Failure to follow these instructions and the requirements
contained therein results in the exclusion of any liability on the part
of the manufacturer. The same applies to the repair specialist who
does not have the necessary qualifications, or uses non-original parts
without obtaining a permission of the manufacturer.
If you have any problems, we strongly recommend that you contact authorized service
centers, addresses and telephone numbers of which you can find out from the company, the
seller or on the website www.autoterm.ru.
Automatic Control Features .
1) if for some reason the heater did not start, the start-up process will be automatically
repeated. After two failed attempts the heater will be switched off;
2) if during the heater's operation burning is interrupted, the heater automaticallyre-starts.
Restarts after consecutive flameouts are performed up to three times;
3) in case of overheating of the heater coil (for example, due to blocked intake or output
of the heating unit), the heater is automatically switched off;
4) if the maximum temperature of the heated air is exceeded (for example, due to closed
outlet of the heating unit), the heater is automatically switched off;
5) if voltage drops below 20V (10V) or increases to more than 30V (16V), the heater
automatically switches off. The numbers in parentheses are for the heaters with the
nominal voltage of 12V;
6) in case of emergency shutdown, the appropriate fault code is displayed on the
Controller display and a LED starts flashing;
7) *if any of the temperature sensors is faulty, the heater does not start and displays a fault
code 32 or 11;
* - only for the heaters of the PLANAR-8D type.
Maintenance .
It is recommended to send the heater for regular maintenance and testing to specialized
service centers.
Many types of repairs and maintenance works on the heater
require professional knowledge and special tools. Improper
maintenance can result in damage to the heater.

5
We recommend to independently conduct the following services:
For optimum performance, the heater should be taken to a specialized service center
for inspection and maintenance at least once a year.
If the heater is not in use, it is necessary to operate it once a month for 5-10 minutes,
including the warm season, to ensure reliable operation of the heater .
Regularly check the battery charge.
Before the start of the heating season, check the fuel tank. If the tank stored fuel for a
long time (for example from the past heating season), it is necessary to drain it! Rinse
the tank with gasoline or kerosene and fill it with fresh diesel fuel. This procedure is
designed to remove sediment formed in the fuel during prolonged storage. Failure to
follow this procedure can lead to clogging or failure of the fuel pump and increased
sooting in the combustion chamber.
In case of a long parking or storing the vehicle, disconnect the heater from the power
source (battery) to prevent it from discharging (current consumption of the heater out
of service is (30 ÷40) mA).
Reliable operation of the heater depends on the grade of fuel used. Fuel grade is
selected depending on ambient temperature.
Malfunctions .
Actions in the event of a malfunction.
check for the presence of fuel in the tank and the fuel line downstream of the fuel
pump;
check the 25A fuses;
check for loose connections in connectors and fuse holders (possible oxidation of
contacts);
disconnect the power connector for 1-2 minutes and re-connect it again.
All other problems can be identified by the fault code, which is displayed on the
Controller.
Attention! If, during start-up and operation of the heater the error message
"Overheating" is repeated 3 times in a row, the heater will be locked. Locking is made
upon actual overheating, regardless of input from the sensors that produced errors. In case
of locking, the controller display will show code 33. To unlock the heater you need to
contact a service center.
We recommend not to wait for the lock of the heater, and immediately after the first
overheating start troubleshooting causes of failure.
Check intake and output of the heating unit for free passage of heated air.
