MK Series Portable Chiller : Air-Cooled : HE INSTRUMENT
D. At full load, the chiller will
discharge approximately
15,000 BTU's per hour per ton
of cooling.
E. On blower units, air discharge
duct work should be sized by
a qualified HVAC engineer.
Sizing shall be according to
rated CFM at the static
pressure of .90 inches of
water. See figure 2.4C
at right.
F. On blower units, a
damper control
assembly is required
in low ambient
temperature areas or
when outdoor air
make-up is used. The
assembly works in
conjunction with
refrigerant head
pressure to regulate
air flow to maintain
proper refrigerant
head pressure when
condenser intake air
temperature will be
less than 60°F. See figure 2.4D to the right.
G. All air cooled units must have all enclosure panels in place before
operating compressor. Air will not be drawn through the condenser
coil if they are not in place. This will cause the compressor to
lockout on the high pressure safety fault.

Electrical power supply requirements for Nema 1 units are
identified on the equipment data plate. Determine the
plant's voltage supply is the same as the unit's voltage
requirements.
WARNING: Do not connect the unit to a voltage supply
not equal to the unit's voltage requirements as specified
on the unit's data plate. Use of incorrect voltage will
void the unit's warranty and cause a significant hazard
that may result in serious personal injury and unit
damage.
