GROUNDING INSTRUCTIONS

THIS PRODUCT IS FOR COMMERCIAL USE ONLY.

ELECTRICAL:

In the USA this machine operates on a standard 15 amp 115V,

60 hz, A.C. power circuit . The amp, hertz, and voltage are listed on the data label found on each machine. Using voltages above or below those indicated on the data label will cause serious damage to the motors.

Fig. B

Tab For Grounding Screw

Adaptor

Fig. C

NOTE: In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code

GROUNDING INSTRUCTIONS:

This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipmentgrounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

This appliance is for use on a nominal 115-volt circuit, and has a grounded plug that looks like the plug in “Fig. A”. A temporary adaptor that looks like the adaptor in “Fig . C” may be used to connect this plug to a 2-pole receptacle as shown in “Fig. B”, if a properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet (Fig. A) can be installed by a qualified electrician. The green colored rigid ear, lug, or the like extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover.

Whenever the adaptor is used, it must be held in place by a metal screw.

!

WARNING:

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the appliance - if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

PERIODIC MAINTENANCE

Twice a month, flush a white vinegar solution (One quart vinegar to two gallons of water) or antibrowning solution (mixed as directed) through the extractor. This will prevent build-up of alkaline residue in the system. If spray jets become clogged, remove the spray tips, wash them thoroughly, and blow-dry.

NOTE: Do not use pins, wire, etc. to clean nozzles as this could destroy spray pattern.

Periodically inspect all hoses, electrical cables and connections on your machine. Frayed or cracked hoses should be repaired or replaced to eliminate vacuum or solution pressure loss. If the cable insulation is broken or frayed, repair or replace it immediately. Don’t take chances with electrical fire or shock.

DAILY / REGULAR MAINTENANCE

Before making any adjustments or repairs to the machine, disconnect the power cord from electrical source.

1.

Empty unused cleaning solution from the solution tank.

2.

Inspect and clean filter screen in solution tank.

3.

Flush pumping system with 4 or 7 liters of clean, hot water.

4.

After each use, rinse tank with fresh water.

Periodically inspect the recovery tank and decontaminate if necessary, using a Hospital

Grade Virucide or a 1-10 bleach to water solution. Waste water should be disposed of properly.

5.

Check for and remove any lint or debris around vac shoe.

6.

Check spray jets for full spray pattern.

MAINTENANCE

7.

Remove lint and dirt build-up from brush and housing.

NOTE: Brush removal.

A. To remove brush, grab and pull brush out from end opposite drive belt (operator’s right). Remove other end from brush driver.

B. To install brush, line up slots in brush core with pin in driver on drive belt side

(operator’s left) and push brush onto driver.

Then snap bearing end (opposite end) of brush into retaining clip.

8.

Check cooling air screen (located on frame behind left wheel) for lint or debris.

Key Features

  • 1 hp vacuum motor
  • 117” waterlift
  • 73 PSI solution pump
  • 7-gallon solution and recovery tank capacity
  • intermittent or continuous brush/spray switch
  • brush height adjustment
  • accessory tool usage
  • clear internal covers

Frequently Answers and Questions

What is the capacity of the solution and recovery tanks?
The CDT7 has a 7-gallon capacity for both the solution and recovery tanks.
How do I adjust the brush height?
Use the brush height adjustment lever to regulate the brush height from storage position to various carpet heights.
What types of cleaning chemicals can I use with the CDT7?
The manual lists various suitable chemicals, including alkalis, detergents, hydroxides, soaps, and vinegar. It also specifies chemicals that are not compatible, such as aldehydes, aromatic hydrocarbons, and chlorine-based bleaches.
What are the intermittent and continuous switch settings for?
The intermittent setting requires the operator to hold the switch in the "on" position with the thumb, and is typically used in small areas. The continuous setting allows the operator to set the switch in the "on" position with one touch, and is typically used in large areas.
How do I use accessory tools?
Insert the hose cuff for the chosen accessory tool into the vacuum shoe hole. Turn on the pump and vacuum switch, and squeeze the handle on the accessory tool to begin cleaning.
