These uncased replacement coils are designed for upflow,
downflow, or horizontal applications.
• Check the coils orifice size and confirm that it’s suitable
for application with the intended outdoor unit. Depending
on application, additional installer supplied orifice or TXV
may be required.
• Verify that the air delivery of the furnace/air handler is
adequate to handle the static pressure drop of the coil,
filter, and duct work.
• If precise forming of refrigerant lines is required, a copper
tubing bender is recommended. Avoid sharp bends and
contact of the refrigerant lines with metal surfaces.
• Refrigerant lines should be wrapped with pressure sensitive
neoprene or other suitable material where they pass against
sharply edged sheet metal.
• Horizontal installations require a horizontal drain pan kit
to be installed. See Table 6 (page 8) for part number.
COil iNStAllAtiON
WArNiNG:
Shut off all electrical power to the furnace and
outdoor condensing unit before performing any
maintenance or service on the system. electric
furnaces may be connected to more than one
supply circuit.
CAUtiON:
the coil must be level to ensure proper
condensate drainage. An unlevel installation
may result in structural damage, premature
equipment failure, or possible personal injury.
1. Disconnect all electrical power to the furnace or air handler.
2. Remove system refrigerant per industry standard practices.
3. Disconnect and remove existing evaporator coil.
System Depressurization
1. Remove the cap (Figure 1) from the end of the liquid line.
2. Verify pressurization by depressing the Schrader valve
on the end of the liquid line. Listen for any escaping gas.
If there is no pressure, test the coil for leakage.
• If leakage is found, clearly mark the location of the leak
and return the coil to the distributor for processing.
