HFCF-SVX01A-EN
Page 12
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.
12
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.

before hoisting.
Coil Cleaning
Clogged or dirty coil will reduce the cooling
capacity. Followings are the cleaning steps:
1. Disconnect the power and motor wire and
stop the fan.
2. Remove the whole fan seat and clean from
the air inlet.
3. Clean the coil fin using rigid nylon brush.
4. Clean it with dust collector.
