Use and Care Manual

28
1. Due to its efcient design, the appliance produces condensate (water) as a normal by-product. This condensate is acidic, with a pH level between
3 and 4. This condensate must be drained away from the appliance and disposed in accordance with all local regulations.
2. Use corrosion-resistant materials approved by the Authority Having Jurisdiction (AHJ) to drain condensate. In the absence of an AHJ, the included
exible plastic hose, or eld supplied ½" PVC and CPVC drain pipe complying with ASTM D1785, F441, or D2665 may be used. Cement must
comply with ASTM D2564 for PVC or F493 for CPVC. For Canadian applications, use CSA or ULC certied PVC or CPVC pipe, ttings, and
cement.
3. Local building codes may require an in-line neutralizer to be installed (not included) to treat the condensate. Follow all the installation instructions
included with the neutralizer. If a neutralizer is installed, periodic replacement of the limestone (or neutralizing agent) will be required. The rate of
depletion of the limestone varies with usage of the appliance. During the rst year of appliance operation, check the neutralizer every few months
for depletion.
4. Route the drain line to a nearby oor drain, laundry tub, or condensate pump.
1. Condensate line must be pitched at least 1/4" per foot to properly drain. If this cannot be done, or a very long length of condensate hose is used,
you must increase the condensate line to a minimum of 1" ID and place a tee in the line after the condensate neutralizer to properly reduce
vacuum lock in the drain line.
2. Plastic pipe should be the only material used for the condensate line. Steel, brass, copper, or other materials will be subject to corrosion or
deterioration.
3. NEVER install condensate lines outside. It is very important that the condensate line is not exposed to freezing temperatures or any type of
blockage. Damages due to frozen or blocked condensate lines ARE NOT covered by warranty.
4. Support of the condensate line may be necessary to avoid blockage of the condensate ow.
5. An error will appear on the appliance display if condensate line is blocked. The appliance will not operate with a blocked condensate line. It is
extremely important to have this condition repaired by a qualied service technician.
PART 6 – INSTALL THE CONDENSATE DRAIN
NOTE: If a nearby laundry tub is used as a disposal for waste water from the washing machine, draining the condensate into this tub allows the
soapy water discharge to neutralize the acidic condensate.
NOTE: This appliance has an internal condensate trap that must be cleaned and maintained. See Maintenance section of this manual for instructions
on maintaining the trap.

CAUTION
CAUTION
CAUTION
If using a condensate pump, select one approved for use with condensing appliances and furnaces. The pump should have an overow switch to
prevent property damage from condensate spillage.
It is very important that the condensate piping be no smaller than ½". To prevent sagging and maintain pitch, condensate piping should be
supported with pipe supports, and pitched ¼" per foot to allow for proper drainage.
The condensate line must remain unobstructed, allowing free ow of condensate. If condensate freezes in the line, or if line is obstructed in any
other manner, condensate can exit from the tee, resulting in potential water damage to property.
