Start Up / Operation

 

 

 

 

 

 

Preparation

 

Before starting the unit, complete the above 
mentioned INSTALLATION CHECKLIST to 
ensure the proper start-up preparation is 
completed. 

 

Operation

 

Fan coil operation can be controlled by a 
simple motor speed switch or a thermostat 
unit. 

 

The wall-mounted thermostat unit usually 
includes a motor speed switch, an on/off 
switch and a thermostat. The on/off switch 
turns the unit on and off and the motor 
speed switch controls the fan speed. The 
thermostat controls the water valve and 
usually has a dial to select an approximate 
setting temperature. 

 

If the associated thermostat is not used for 
control, the installer should choose other 
type of thermostat which complies with the 
safety codes. 

 

The  simple  motor  speed  switch,  labeled  Off- 
Hi-Med-Low, controls the fan coil by turning the 
switch  to  different  speed  for  adjusting  the  air 
flow. 

 

 

 

 

 

 

 

 

 

 

For the unit with electric heater option, a 
high temperature cutout with automatic reset 
(105

  cutout, 85

  auto reset) is provided 

to de-energize electric heat in 
the event of an overheat condition. In addition 
to the automatic reset cutout, the unit also 
equipped with another high temperature 
cutout with manual reset (130

  cutout). 

These two temp. cutouts provide double 
protection for electric heat operation. 

 

Coil Venting

 

When water is first introduced into a coil, air 
is sometimes trapped in the coil tubing. This 
trapped air has a tendency to collect at the 
highest point in the coil. Therefore, a manual 
air vent is installed at the highest point of the 
header. When there appears to be air trapped 
in the coil, resulting in "bubbling" or 
"clanking" noises within the unit, release air 
from the manual air vent by rotating the knob. 
A pair of pliers can be used if the knob is too 
tight to turn by hand. Turn knob counter 
clockwise 1-2 turns and allow air to flow out 
of the air vent until a steady stream of water 
appears. Then retighten knob. 
 

Coil drainage 
When the coil need to maintenance, or 
protected the water frozen in the low 
temperature condition,  you should turn the 
water vent  for drainage the water in the coil. 
The operator manner just like as the air vent.
