element(s) by loosening the screws (Figure 12). 

Remove the screw-in element(s) by turning the 

element(s) counterclockwise with a 1-1/2 inch socket 

wrench. Remove the existing gasket(s).

Clean the area where the gasket(s) fits to the tank 

7. 

and internal threads. If you are replacing the bottom 

element, remove any accumulated sediment on the 

bottom of the tank.
Make sure the replacement element(s) has the correct  

8. 

voltage and wattage rating by matching it to the rating 

plate on the water heater. Position the new gasket(s)  

on the element and insert it into the water heater   tank 

(Figure 13). 

NOTE:

 Apply a light coat of hand dishwashing soap 

and water to the gasket. Tighten the element by turning 

it clockwise until secure.
Close the drain valve and open the nearest hot water

faucet. 

Then open the cold water shut off valve

 and 

allow the tank to fill completely with water.  To purge 

the lines of any excess air and sediment, keep the hot 

water faucet open for 3 minutes after a constant flow of 

water is obtained.

Check for leaks around the element(s).

Routine Preventive Maintenance

At least monthly, a visual inspection should be made of the 

following:

Air Filter (Remove and inspect, clean if needed, and 

• 

reinstall).
Condensate drain pan and condensate lines.

• 

The lower metal drain pan for standing water which may 

• 

indicate a clogged condensate drain pan, condensate 

lines, or plumbing leak.
Leaking or damaged water piping.

• 

Presence of corrosive materials in the installation area.

• 

Presence of combustible materials near the water heater.

• 

After servicing this water heater, check to make sure it 

• 

is working properly. (See “Operating Your Water Heater” 

section of this manual.)

IMPORTANT:

 If you lack the necessary skills required to 

properly perform this visual inspection, you should not 

proceed, but get help from a qualified person.

Cleaning the Heat Pump

Air Filter Cleaning/Replacement

IMPORTANT:

 Before attempting to clean or replace the air 

fi

 lter press the power button to place the water heater in 

Standby Mode and turn-off power to the water heater at the 
circuit breaker/fuse box.

Locate the screw securing the filter panel to the heat 

1. 

pump shroud and loosening it.
Remove (slide) the filter from the unit.

2. 

If you are replacing the filter skip to step 4. To clean the 

3. 

filter use a vacuum with a hose attachment to remove 

any dust or debris.
Place the new or cleaned filter into the water heater 

4. 

and secure the filter to the shroud with the screw 

loosened earlier. 

NOTE:

 The guides/slots when inserting the filter into 

the water heater. 
Restore power to the water heater and press the 

5. 

power button to turn the water heater on. 

NOTE:

 the 

water heater will conduct a system diagnostic prior to 

operation. 

Inspection/Cleaning of the Condensate 
Drain Pan & Condensate Drain Lines

IMPORTANT:

 Before attempting to clean or replace the 

condensate drain pan or lines press the power button to 
place the water heater in Standby Mode and shut-off power 
to the water heater at the circuit breaker/fuse box.

Remove the access panel (fan side) by loosening the 

1. 

screws securing it to the unit. 
Check the condensate drain pan and drain lines for any 

2. 

dirt or debris that might interfere with proper drainage. 

Wipe out any dirt or debris with a damp cloth.
Once the condensate drain pan and lines have been 

3. 

inspected/cleaned, secure the access panel to the water 

heater.
Restore power to the water heater and press the power 

4. 

button to turn the water heater on.
