Instruction Manual

MADE IN KOREA
The unit does not run.
The unit makes loud noises
when running.
The unit runs but does not
pump the liquid out.
Liquid drains back into the
pump from the outlet piping.
Liquid leaks from around
the check valve.
a) Check the power supply.
b) Check the appliance to see if the
condensation is actually being produced.
c) Make sure the inlet piping is not clogged. If it is
clogged, the appliance may eventually be damaged.
a) Make sure the inside of reservoir is clean.
b) Make sure there is no siphoning action.
a) Check that the highest point of the outlet piping does
not exceed the maximum delivery head of the pump.
b) Check that the inside of outlet piping is clean.
c) Inspect the check valve following the maintenance
instructions.
a) The check valve may have debris in it. Clean the
check
valve following the maintenance instructions.
a) Make sure the outlet piping is tightly connected with
the check valve.
b) Make sure the check valve is fastened properly.
c) If the o-ring under the check valve is damaged,
replace with a new one.
DRAIN CONNECTION
1. Position the pump beneath the equipment / unit so that condensate or high temperature
discharge water flows into the pump inlet freely (use either of the two openings provided). When
pressurized hot water is connected always use a tundish prior to entering the pump.
2. The inlet pipe should be positioned as close to the bottom of the tank as possible and the
bottom cut at an angle of greater than 30° to ensure the free flow of the condensate from the
boiler.
3. If the pump is to be used for both boiler condensate & PRV discharge, the copper PRV pipe
should only be inserted at least 1.4” (but no greater than 1.8”) into the tank inlet.
INLET CONDENSATE DRAIN CONNECTION
1. Connect the 3/8” I.D tubing to the discharge adapter / non return valve. For best results, secure
tubing with clamp but do not pinch, or restrict the tubing. The non return valve has a quick
release mechanism with a 1/4 turn bayonet type fitting.
2. Tubing should rise vertically but not exceed the maximum shut off head (pumping height)
of 46’ above the pump. Any horizontal runs should be taken into consideration when assessing
the maximum shut off. This shut off will be reduced if bends and horizontal runs are included in
the outlet pipe work. If in doubt please contact DiversiTech for advice.
3. At highest point angle tubing horizontally and create a downward slop to drainage point. Do
not bend sharply or twist the tubing in a way that might result in collapse or restriction of the
tubing. Creating a downward slope will allow condensate to drain by gravity and keep tubing
empty.
4. If not possible to create a downward slope, try to create an inverted “U” trap directly above
the pump at the highest point.

COMMISSIONING & TESTING
1. Before commissioning, check for debris in the tank. Remove any material which might block the
drain line or drain into the pump tank.
2. Turn on power and slowly fill the tank with clean water, as the float rises to the on level position the
motor should turn on.
3. Leave the clean water in the tank as this will effectively prime the pump ready for use and help to
prevent any flue products passing through the pump from the boiler condensate drain pipe.
This pump is designed for use with condensing boiler applications. Caution must be taken to ensure
acidity of condensate does not increase below the average pH of 2.8 (to prevent pitting) by routinely
cleaning or flushing tank with fresh water.
MAINTENANCE & SERVICING
1. Before servicing the pump, disconnect the electric power for both the pump and the equipment
unit.
2. It is recommended that the pump be checked every six months for proper operation. It is
important to check for debris which may cause a blockage to the pump discharge
adapter/non return valve. Check for proper free movement of pump float and switch and
check for free, unrestricted movement of motor and fan.
3. Clean the holding tank and float with warm water and mild soap. Rinse completely when finished.
4. Check the inlet and outlet piping. Clean as necessary. Be sure there are no kinks in the outlet
line that would inhibit or restrict flow.
