Руководство По Обслуживанию для Sigma Force Flow Heaters

All units are shipped fully assembled. If the 
unit is a fully or semi-recessed model type 
then a wall seal trim will be included and 
must be installed as per the provided 
instructions. 

Remove front panel, line up roughed in 
piping  and position the unit in the desired 
wall or ceiling location. 

Attach unit to wall or ceiling using the 
provided holes in the back panel of the unit. 

Piping should always be installed and 
connected using good practice and in 
accordance with applicable codes. 

Wiring should be completed in accordance 
with applicable codes. All models are 
furnished with a fan control box in the 
desired location on the unit. If the speed or 
temperature control are to be remote 
mounted the junction box must be supplied 
by an other. 

Once the unit is completely installed a test 
run should be performed. If operational 
difficulties are experienced, recheck all 
wiring connections and power source. 

Motors. Motors are a permanent split 
capacitor type fitted with self lubricating 
sleeve bearings. In order to extend motor life 
the bearing should be "recharged" with an 
annual lubrication. Use an SAE 10 non 
detergent oil applied only in the oiling holes 
provided. 

Coils.    Coils are to be kept clean in order 
for proper heat transfer to exist. The 
conditions of each operating environment 
will change the frequency of cleaning. The 
coils can be vacuumed or alternately use the 
following methods. Brush the fins on the air 
intake side and then place a bag or damp 
cloth over the unit discharge. Activate the 
unit and the dirt will be trapped in the bag or 
cloth. The coil can also be cleaned with high 
pressure air which should be blown on the 
outlet side of the coil (blowing air on the inlet 
will force dirt deeper into the coil).  

Blowers.  Blowers can be cleaned using 
high pressure air. 

Filters.   Filters should be kept clean to 
ensure the proper circulation of air volume 
through the unit. The frequency of the 
cleaning varies and is dependant upon the 
operating environment. As a guide they 
should be washed in mild detergent or blown 
clean with compressed air every 3 months.
