to obtain values of Suction/Discharge pressures and
Superheat/Subcooling.
Note the Superheat value before disconnecting the
system. All EMI systems are designed to operate at
optimum capacity and efficiency when running 10° F
Superheat (+/- 2° F) at ARI rating condition of 80/67°
F indoors and 95° F outdoors. Since most startups are
not done at these exact conditions, it is critical to follow
the superheat chart values for given outdoor conditions
when fine tuning the system charge. The other values
should be close under most conditions.
REMOTE THERMOSTAT PLACEMENT
EMI systems can be installed with remote mounted
(wall) thermostat control (24v Class-II low voltage circuit).
Use a thermostat that will provide a signal to the G termi-
nal.
NOTE:
A signal must be present at the G
terminal to operate the evaporator fan in heat
mode.
The thermostat should be mounted 60 inches from the
floor on a warm (i.e., INSIDE) or post away from doors,
drafts, or high traffic areas.
FIELD INSTALLED KITS
EMI provides certain kits to modify your existing unit.
We have kits available for widespread use in EMI systems,
including:
Low Ambient Kits (cooling only- ALWAYS field in-
stalled)
Hard Start Kits (ALWAYS field installed)
Condensate Pump Kits (field installed for certain
evaporator models)
Specific Control Changeover Kits (i.e., Unit Mount
to Remote T-stat) for some older model EMI evapo-
rators.
Consult factory technical service representative to
choose the exact kit that you will need for your EMI model
unit. Kits change periodically so a kit that worked in one
model year may not work for a unit manufactured in a dif-
ferent model year.
NOTE:
EMI does not stock or recommend
electric heat add-on kits for field installation.
It is critical that, if you can foresee the need
for electric heat in your EMI evaporator, you
initially order it as a factory installed option.
Adding an electric heater in the field has proved to be
complicated and difficult due to space constraints and/or
the unit being mounted into position already.
EMI will not accept responsibility for the rework per-
formed. EMIs safety approval listing (ETL) becomes void
at the time a field rework that involves an electric heater
takes place since several items, including breaker size, wire
size, and unit rating are immediately effected.
SYSTEM DATA
If, after routine inspection and adjustments, the sys-
tem is not performing up to standards, call EMI Customer
Service for assistance. It is important that the System Data
Form (see following page) be completely filled out and, if
possible, FAXED to our service group at 1-800-232-9364.
With this information in hand, we can prepare to help you
and handle the situation in a timely and effective manner.
Complete parts listings are available from your dis-
tributor or from the EMI factory. All parts orders must be
entered with the distributor who supplied the original equip-
ment order. If assistance is needed for identifying a part num-
ber or description, please call EMI Customer Service.
When calling EMI for service assistance and/or parts
orders, you will need to provide the complete unit model
number and serial number as obtained from the rating plate
attached to the equipment.
