Do not dispose of materials such as paint thinner or other
chemicals down drains. Doing so could chemically attack and
damage pump system components and cause product
malfunction or failure.
Do not use pumps with fluid over 150°F (65°C). Operating the
pump in fluid above this temperature can overheat the pump,
resulting in pump failure.
Do not use pump system with mud, sand, cement,
hydrocarbons, grease, or chemicals. Pump and system
components can be damaged from these items causing
product malfunction or failure. Additionally, flooding can
occur if these items jam the impeller or piping.
Do not allow pump to freeze.
General Information
Before Installation, read the following instructions carefully. Each
Liberty Pumps product is individually factory tested to assure
proper performance. By closely following these instructions,
potential operating problems should be eliminated, providing
years of trouble-free service.
Installation
A.
Select a location that is level and below the condensate pan
drain. The unit may be mounted on a wall by using the
mounting tabs on the tank, which are 17.6” apart.
B.
Connect the drain pan. Use vinyl tubing, PVC, or any other
suitable material. Be sure the tubing or pipe extends into the
inlet of the tank by at least 1".
Connect as follows:
STANDARD
condensate (dehumidifiers, A/C, etc.) can be
connected to any of the three intake holes (1), (2), (3).
ACIDIC
condensate (high-efficiency boilers and furnaces)
must be installed in inlet (4) or (5).
C.
The discharge connection to the check valve may be made
with 3/8” vinyl tubing secured by a hose clamp (not included),
or the barb may be removed by sawing so that threaded
fittings may be attached. The thread is 1/4” NPT.
Connect discharge hose or pipe to the pump.
Only
hand-tighten discharge fasteners.
Over-tightening may cause
the discharge housing to crack and leak. Once the discharge
tubing has been extended to the required height it should be
slanted downward, if possible, to assist in drainage.
Note
: For
best results, do not extend discharge tubing beyond 17'
vertically.
D.
The safety switch leads should be connected to a Class 2 low
voltage circuit (not to exceed 30 volts). Using this feature may
prevent damage from condensation overflowing if the
discharge becomes blocked or if the pump fails. The leads
may be connected in series with the low voltage thermostat
circuit so as to shut down the heating/air-conditioning
system if the water level in the pump tank rises beyond
normal, or they may be connected to an external alarm.
E.
If necessary, the pump unit may be removed and rotated 180°
to make access to the plumbing inlet and discharge lines
easier. To rotate the pump:
1. Remove the clear neutralization chamber cover by
inserting a screwdriver in the slot and prying the tank
outward.
2. Remove the pump unit using the same process.
3. Rotate the pump, and snap it back into place.
4. Snap the neutralization chamber cover back in its initial
position.
F.
When all mounting and water connections are secure,
connect the unit to an electrical supply. Disconnect electrical
power at fuse or circuit breaker box before making any
connections. The power cord must be connected to a
constant source of power (not a fan or other device that runs
intermittently) matching the voltage specified on the pump
nameplate.
If connecting a pump with a stripped wire cord end, power
connections must be made within a junction box or
appropriate enclosure and must comply with the NEC and
any applicable codes. Wiring is as follows: GREEN is ground,
BLACK is line, and WHITE is neutral (115V) or line2 (230V).
G.
To ensure proper installation, energize power and test the
unit by adding water to the tank until the pump activates. Be
sure the water discharges properly. Finally, check the
connections for leakage and proper discharge pipe routing.
Maintenance and Troubleshooting
Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.
Always disconnect the pump from power source before
attempting to service the pump. Fatal electrical shock could
occur.
Maintenance
Pump models have sealed permanently lubricated bearings and
require no additional lubrication.
Quarterly
Check the outlet pH level using a pH strip or electronic pH meter.
The cartridge kit must be replaced the sooner of (1) annually or (2)
if the pH at the outlet drops below 5.0 (or the minimum level of
the local water authority). Use
only
Liberty Pumps replacement
cartridge kit #K001898. To replace the neutralization cartridge,
remove the neutralization chamber cover, exchange the cartridge
and replace cover.
Inspect the condensate pump tank to ensure it is free of
accumulated dirt or sludge.
Do not
use solvent cleaners. Clean
tank with mild soap and warm water only. Clean inlet and outlet
piping. Reassemble system and check for correct operation.
Pour enough water into the tank to activate the pump when not
normally in use.
As Needed
If unit is mounted in an unheated area that is exposed to
temperatures below freezing, the unit and lines must be drained
to prevent damage to the pump.
