adversely affect that area, i.e. continued sump
discharge into a flower bed for example, where the
input water contains CaCO3 (lime) will eventually
decrease the pH of the soil.
Sewer Discharge
The quantities of mineral and debris flushed are
actually very small, and do not cause problems when
diluted in normal sewer flow. However, local, state or
federal standards and restrictions must be followed in
any given locality.
Make Up Water Solenoid Valve
This valve is controlled by the UCM based on water
level in the sump, as well as whether a call for
mechanical cooling exists. During low ambient
temperatures, the solenoid valve will be de-energized
preventing water from further filling sump. The sump
drain valve opens to empty sump of water. Operation
can be extended to 10 deg by providing an optional
sump heater.
Drain Valve
The drain valve is shipped to “drain during power loss
conditions”. If “hold during power loss conditions” is
desired, refer to
“Evaporative Condenser Drain Valve
Setup,” p. 94
Gas Heat Units
All internal gas piping is factory-installed and pressure
leak-tested before shipment. Once the unit is set into
place, the gas supply line must be field-connected to
the elbow located inside the gas heat control
compartments.

Access holes are provided on the unit as illustrated in
Figure 52, p. 68 to accommodate a side or bottom pipe
entry.
Following the guidelines listed below will enhance both
the installation and operation of the furnace.
N No otte e:: In the absence of local codes, the installation
must conform with the American National
Standard Z223-1a of the National Fuel Gas Code,
(latest edition).
1. To assure sufficient gas pressure at the unit, use
Table 23, p. 66 as a guide to determine the
appropriate gas pipe size for the unit heating
capacity listed on the unit nameplate.
2. If a gas line already exists, verify that it is sized
large enough to handle the additional furnace
capacity before connecting to it.
3. Take all branch piping from any main gas line from
the top at 90 degrees or at 45 degrees to prevent
moisture from being drawn in with the gas.
4. Ensure that all piping connections are adequately
coated with joint sealant and properly tightened.
Use a piping compound that is resistant to liquid
petroleum gases.
5. Provide a drip leg near the unit.
6. Install a pressure regulator at the unit that is
adequate to maintain 7" w.c. for natural gas while
the furnace is operating at full capacity.
IIm mp po orrtta an ntt:: Gas pressure in excess of 14" w.c. or 0.5
psig will damage the gas train.

Failure to use a pressure regulating device will
result in incorrect gas pressure, which can cause
erratic operation due to gas pressure fluctuations as
