For HRP series condensate pump

Introduction

Hitech condensate pumps are designed to automatically remove the condensate from an air-conditioner, evaporator coil and/or an oil or gas condensing warm air boiler. This pump is made from a tough ABS plastic body so it will resist corrosion and impact.

Installation

1. Carefully unpack the unit and check for damage and make sure all required part are included.
   
   
2. Choose a mounting location near the air-conditioner or boiler.
   The pump must be mounted level. And the inlet must be below the lowest drain.
   
   
3. Connection pipe:
   
   • Run flexible tubing or pipe on the condensate drain on the evaporator pan or /and drain from boiler to inlet hole on the pump.
     
   • Connect the discharge line by hand-tighten the cap nut of the check valve in a clockwise direction.
     
   • For the best result, the drain should be below or approx. level with the bottom of the pump tank.
     
     
4. Testing
   With the unit plugged in and the discharge line in place, pour water into the pump reservoir until the unit activates to verify the unit works properly.
   

Maintenance

Warning! Before attempting any maintenance on the unit, disconnect the power cord from the power supply to reduce the risk of electrical shock.

1. Cleaning the check valve and verify its operating
   
2. After unscrewing the cap nut remove the discharge line from the check valve
   
3. Use a wrench to remove the check valve from the drive unit.
   
4. Visually check the valve for obstructions. If damaged, replace.
   
5. To re-install the check valve, hands tighten it to the drive unit.
   

Then, tighten 1/2-turn further with a wrench. Be careful not to over-tighten as this may distort the O-ring seal under the check valve.

Replacement items
The discharge nipple with integrated check valve is available for replacement. It can be used for both pump models.

Troubleshooting

If the pump does not function properly, refer to the following :

1. Unit does not run:
   
   • Check the power supply
     
   • Check the appliance to see if condensation is actually being generated
     
   • Check to make sure the pump float mechanism moves freely and clicks the activation switch when moved up and down.
     
   • Check the drain line(s) into the pump for obstructions. Note: If these lines are clogged and remain clogged, the appliance may eventually be damaged.
     
     
2. Pump makes loud noise when running :
   • Check the tank for debris and clean if necessary. Refer to the maintenance section for cleaning instructions.
     
     
3. Unit runs but does not pump liquid out :
   • Check the floats to be sure that they are not stuck in the up position.
     
   • Check the height of the discharge tubing to be sure it does not exceed the allowed head (see specifications)
     
   • Check the discharge tube for obstructions and clear if needed.
     
   • Check the check valve for obstructions. Refer to the maintenance section for cleaning instructions.
     
     
4. Liquid drains back into pump from discharge line :
   • Check valve may have debris in it. Refer to the maintenance section for cleaning instructions
     
   • If the discharge line is plumbed so the highest point is less than 1 m above the pump, the check valve may allow liquid to drain out of the line. This is normal and will not damage the pump.
     
     
5. Liquid leaks from around the check valve
   • Check the proper fit of the cap nut that holds the discharge tube in place.
     
   • If the check valve is too tight or too loose it may leak around the O-ring. Check that the valve is hand tight, and then tighten an addition 1/2 turn with a wrench.
     
   • If the O-ring under the check valve is damaged, replace with a new one or purchase a replacement check valve, which includes an O-ring.
