PLACEMENT CONSIDERATIONS
Seasonal Wind and Winter Installation Precautions
To ensure the chiller operates properly, certain measures are required in locations where strong cold winds, heavy snowfall, and freezing
temperatures could occur.
Consider chiller fan operation when installing in snow-prone areas. If the chiller fan is installed below a certain level, it could trigger a high pressure
error within the circuit and cause operation malfunction.
1. Snow could access the air discharge outlet of the condenser and
freeze inside the chiller; in areas with potentially high snowfall
amounts, install a cover over the chiller to prevent snow accumu-
lation on its top.
2. The interior of the chiller could freeze if the air inlet becomes
clogged with snow. Install the chiller in such a way that snow
drifts do not blow into the air inlet, and install a hood to block the
unit from heavy snow. Clear the area of snow around the chiller
heat exchanger.
3. Install the concrete slab or base materials (plus spring isolation)
so that the chiller is 4 inches (102 mm) higher than the accumu-
lated snow (the chiller is to be installed 4 inches [102 mm] above the average accumulated snowfall for the geographical area).
4. If more than 4 inches (102 mm) of snow has accumulated on top of the chiller, remove the snow, and then operate the unit.
5.
The height of the concrete slab or base materials (plus spring isolation) should not exceed the width of the chiller.
6.
Do not install the chiller in an area where heavy snow accumulation could negatively impact chiller operation. Position the chiller in
such a way that the side with the air heat exchanger does not face the direction of the snow (ensure the side with the air heat exchanger
is parallel to snowfall direction). Add a wall high enough to prevent any snow accumulation from being drawn up into the coil side of the
chiller (field installed).
7. If seasonal winds are strong and blow predominately from one direction, chiller capacity could be reduced or load imbalance could occur;
therefore, install the chiller so that the product cycle is not impacted. If that isn’t possible, install a windbreaker, hood, etc. In locations with
strong seasonal winter winds (especially near coastal areas), install a hood, taking into consideration wind direction, that doesn’t block the
suction inlet of the chiller. If the chiller will be directly exposed to seasonal winter winds, field-install a wind baffle (in addition to the hood).
8.
Do not install the chiller near an edge of a rooftop or overhang. Snow can fall off the roof or overhang and into the chiller.
Do not
allow snow to accumulate between the outside wall and the
chiller. If snow accumulates in this location, chiller operation will
malfunction due to reduced airflow.
