6.3-2 Electrical accessories
6.3.-2.1 Speed regulation
The supply voltage determining the speed of the fan of the SAVANA Heat unit can be regulated.
Minimum permitted voltage is 125 V.
• -to regulate the fan speed of SAVANA Heat units, no frequency converter may be used!
• -- In case of ceiling installation, take heat radiation from the water exchanger to the motor into account, and
ensure that regulation enables cooling of the water exchanger rst followed by motor turn o, when the
unit is switched o.
• -Failing that, there is a risk of reduced service life of the motor or its damage. Should this procedure not be
observed, a claim regarding possible motor damage will not be admitted.
• -For detail description of fan regulation see manuals of individual regulators.
6.3.-2.2 Water exchanger regulation
If the fan is o, it is recommended to stop the hot water supply to the exchanger. High temperatures inside the
unit may reduce the service life of the fan!

8.1 PERIODIC CLEANING OF HEATER UNIT
During maintenance of the heater unit, main el. power supply must be o. It is necessary to let the unit cool
down prior to maintenance works!
For any manipulation with the unit, it is necessary to wear protective gloves to avoid injury from sharp edges!
• -spanner, size 10 mm
• -vacuum cleaner
• -hand brush
• -rag
• -non-aggressive cleaning agent (soap water)
It is recommended to carry out periodic checks of unit and lter condition after each 500 hours of operation,
and also before and after the heating season.
If the heater unit is not in operation for extended time, we suggest turning the unit on for at least one hour
once every six months.
Adapt lter checks to local conditions.

During maintenance of the heater unit, the main power supply must be o. It is necessary to let the unit cool
down before maintenance works!
For any manipulation with the heater unit, protective gloves must be used to avoid injury from sharp edges!
If you are not sure by correctness of your steps, do not start any repairs and call the professional service!!!
Possible problems …
If you cannot nd, remove the defect or if it requires intervention to the device, please call an authorised
service!
9. TROUBLESHOOTING
Device behaviour Anticipated problem Solution
The device is noisy
Air in the device. De-aerate the device by increased pres-
sure and ow of the heating medium.
Stop valves on the device are not
fully open. Open fully the stop valves.
Damaged fan bearings.
Impeller shows clearance or cannot
rotate freely.
It is necessary to dismantle the fan and
replace bearings in an authorised
service, or replace the complete fan.
Unbalanced impeller of the fan
rotates freely, but vibrates shortly
when the fan is turned on.
Dismantle the fan and give it to
a professional service for balancing.
Insucient heat capacity
of the heater unit
Air in the unit exchanger.
De-aerate the exchanger using
air release screws
The exchanger is chocked strongly.
Dismantle the fan and clean the ex-
changer. Use preferably hot water or
steam for cleaning. Do not use aggres-
sive detergents.
Stop or regulation valves on the
device are not fully open.
Open fully the stop valves, and check
whether the regulation valve is open.
Incorrect rotation direction of the
mixing valve.
Correct el. connections on the terminal
board of the regulation.
Clogged lter. Replace or clean the lter thoroughly.
