4.)

DO NOT EXPOSE THE MACHINE TO FREEZING TEMPERATURES:

This can ruin the coils, pumps and flow switch. Winterize the machine when

necessary. This can be done by running anti-freeze or windshield wiper fluid
through the garden hose, as you do when you descale a machine. See DESCALING

Section. The Ultra 250, 600 and 1300 models require 1 to 2 gallons of fluid to

completely fill the coils and water system. When you are ready to resume using
the machine, flush thoroughly and dispose of the anti-freeze carefully before

heating the system.

DESCALING PROCEDURE:

1.)

Obtain THERMA-KLEEN® descaling compound from your salesman or use
equivalent product. Only use THERMA-KLEEN® recommended product safe for
aluminum coils.

2.)

Place in a bucket in concentrated form or mix according to manufacturer’s
instructions. (½ gallon of descalant is needed).

3.)

Remove nozzle from the wand.

4.)

Turn water supply and pump “ON” as if you were going to start the machine. After
the pump is primed, quickly turn “OFF” the pump and water supply and disconnect

the hose from the water connection and place the garden hose into the bucket
along with the wand end.

5.)

Quickly turn “ON” the pump and let the solution circulate through the machine for
about five (5) minutes. Flush the unit with clear water before starting the machine.

6.)

If you are winterizing the unit, 1 gallon is needed for the Ultra 250 & 600 and 2
gallons of liquid is needed for the Ultra 1300. Watch for the solution to exit the

wand. Quickly shut- off the pump.

MAINTENANCE OF PUMPS:

ULTRA 250:

The pumps used on these models are factory sealed. When replacing a pump or motor it
is necessary to re-lubricate the plunger and bearings. Use synthetic grease with PTFE.

We recommend this brand: Super Lube. Check for sufficient lubrication as a

maintenance procedure to extend the life of your pump and motor. Repair a pump as
needed to prevent damage to the motor and/or bearing. Check the pump pressure on a

regular basis.

All pumps:

The warranty will be void if you do the following:
