Installation

Equipment Inspection
Inspect all cartons and packages upon receipt for damage in transit. Remove cartons and check for
concealed damage. Important: Keep the unit upright at all times. Inspect refrigerant circuit for fractures
or breaks. The presence of refrigerant oil usually indicates a rupture. If damage is apparent, immediately
file a claim with the freight carrier.
Units that have been turned on their sides or tops may have concealed damage to compressor motor
mounts or to the oil system. If the unit is not upright, immediately file a claim for concealed damages
and follow these steps:
1. Set unit upright and allow to stand for 24 hours with primary power turned on.
2. Attempt to start the compressor after 24 hours.
3. If the compressor will not start, makes excessive noise or will not pump, return the unit to the freight
carrier.
Installation Requirements
1. Inspect unit for completeness. Check for missing parts (e.g. hardware).
2. Remove access panels and check for loose wires. Tighten screw connections.
3. Complete and mail the warranty registration card.
1.6

Pre-Installation Testing

The ECU may be operated prior to mounting on the cabinet.
1. The ECU must be upright in the proper mounting position for at least 24 hours prior to starting.
Failure to do this will cause permanent damage to the refrigerant system.
2. Turn power off. Attach 208/230V, 1 phase, 60 Hz power to the L1 and L2 terminals in the Control
Box. Jump terminals 10 to 1 on Low Voltage Terminal Strip. Set Compressor Time Delay to
minimum position. Turn power on to the unit. The evaporator blowers should be blowing air and
the compressor should be operating. However, the condenser blower will not turn on until there is
sufficient refrigerant pressure. The evaporator coil air should be approximately 15°F to 20°F (8°C
to 11°C) cooler than the ambient air. If the unit does not come on, check to make sure that unit has
power.
After unit has operated for five to ten minutes, remove power and jumpers, and proceed to mounting
of the ECU.
1.7 Mounting of the ECU
1. The unit has internal mounting holes and a bottom bracket. See drawing for location of all holes
and cutouts for return and supply air. The return air opening must be at least one square foot.
2. Making sure that cutouts do not interfere with components inside your cabinet, cut the holes in the
cabinet door or wall for the return and supply air. Proper alignment of return and supply openings
is essential for proper cooling of the ECU.
