1.1. Quick Start Guide

Note this manual is for the US type configuration with 115V or 230V 60Hz supplies. For

230V 50Hz units, please refer to the appropriate manual.

SAFETY NOTICE!

• Read the User Manual before using the compressor

• Disconnect the power and depressurize the filter housing before removing the housing

• The compressor should not be run continuously for more than 45 minutes after which it needs

15 minutes rest.

Prior to operation

• Verify the plug meets local codes, and that the electrical outlet is able to supply the required

current at the required voltage.

• Place the compressor on a flat stable surface or solid surface. Keep a safe distance from wall.

A pitch of up to 20° from Horizontal is permissible.

• Check the oil level is at the mid point of the dipstick or higher, and if necessary top off the

oil.

• For the first time it is operated, run the compressor for 5 minutes with the condensate drains

open.

• Connect the pressure vessel.

• Close the output fill valve if present, or the valve on the pressure vessel.

Running the compressor

• Turn on Compressor.

• Residual high pressure within the compressor may prevent the motor (either gas or electric)

from turning over. If so, open condensate drain valves or output fill valve and vent some of

the residual pressure.

• For the first time it is operated or after an extended period of non-operation, run the compres-

sor for 5 minutes with the condensate drains or output open.

• Insure both condensate screws are closed

• Once output pressure rises to1500 psi (100 bar), slowly open the fill valve.

• Drain the condensate every 15 to 25 minutes while operating by opening the final and inter-

mediate drain screws briefly until the accumulated condensate is released.

• Supervise compressor during filling.

Finish filling

• Turn off the compressor

• Close the filling valve

• Slowly open the bleed screws on the filling hose (if so configured) until the pressure within

the fill hose is released, then the pressure vessel can be removed.

• Open final Condensate screw slowly, capture condensate and dispose of accordingly. Repeat

for intermediate Condensate Drain.

• If the compressor will be out of use for an extended period, run the compressor with both

condensate fill valves open for a minimum of 1 minute.

KT-70E / KT-90E / KT-70SE User Manual Page 6 of 59 24 April 2018

Maintenance

• Filter cartridges should be changed on the interval described in 8.3, or once per year.

• Top off the crankcase oil each time the filter is changed.

• Once a year or every 500 operating hours change the crankcase oil.

• Check the oil level before each use.

ATTENTION in case of malfunction, depressurize compressor and remove power

2. Product Description

2.1. Intended Use

The compressor is exclusively for compressing air at an operating pressure of 4500 psi

with a maximum pressure of plus 10%. The compressor block is designed for intermittent

operation. The maximum duration must not exceed 45 minutes. After a rest time of 15

minutes is necessary. This represents a total investment of 4 Nm. Any other use or ex-

tended use is considered improper. The manufacturer is not liable for any resulting dam-

age. The risk is borne solely by the user.

It is expressly prohibited to draw gases other than air. Operation in a Nitrox environment

up to 36% oxygen concentration is permitted.

Intended use also includes observing the operating instructions and compliance with the

inspection and maintenance conditions.

The 2.5 CFM KT-70E and KT-70SE are tailored to the specific requirements of filling

air tanks of up to 20L. The 3.2 CFM KT-90E is suited for filling air tanks of up to 45L.

Their construction has been designed for this purpose.

The KT-70E and KT-90E are targeted at SCUBA and other markets using DIN 200 or

DIN 300 couplers. The KT-70SE “Shooter’s Edition” is intended for Air Gunners and

Paintball enthusiasts using a foster style Quick Disconnect on their air cylinders.

2.2. Construction

The main structure of the compressor is made up of the following components:

Standard equipment high pressure compressor:

• housing

• drive

• Compressor block

• filter unit

• filling unit

Standard accessories:

• Filling hose for 4500 psi (300 bar DIN connector) or 3000 psi (200 bar DIN connector)

for “E” series compressors, or Quick Disconnect for “SE” series.

• an intake filter (in housing)

• a high-pressure compressed air filter with filter cartridge

• On-off switch

2.3. Optional Equipment

The KT-70E and KT-90E are offered as one of three configurations, based on the intended

use, and the user’s budget.

• Base Configuration: (Base Option) The base configuration groups together the pres-

sure gauge, safety valve, and DIN connector on the end of the fill hose. After filling,

pressure is relieved in the fill hose as part of the process of draining the condensate,

by opening the final condensate drain.

• Configuration 1 (C1 Option): C1 adds a Minimum Pressure Valve (also called a Pri-

ority Valve), as well as a fill valve and bleed valve to the end of the fill hose, and

moves the safety valve to the Compressor housing.

KT-70E / KT-90E / KT-70SE User Manual Page 15 of 59 24 April 2018

• Configuration 2 (C2 Option): C2 builds on the C1 configuration, and adds the Auto-

matic Shut-Off and Hour Counter.

The KT-70SE is configured with a fill valve with bleed, and a fill hose with a Quick Discon-

nect coupling. The Automatic Shut-Off and Hour Counter are optional on the KT-70SE

2.3.1. Automatic shut-off.

If configured with the automatic shut-off, the compressor will fill the target cylinder to

the maximum rated pressure of the compressor, then turn off the motor.

2.3.2. Hour counter.

If configured with the Hour counter, the operating hours will be displayed on the hour

counter, mounted on top of the electrical motor.

2.3.3. Minimum Pressure Valve.

If configured with the Minimum Pressure Valve, air will not flow out of the filter until

the minimum pressure is achieved (150 bar, or 2200 psi, minimum), and when a large

cylinder is being filled, the pressure within the filter will be maintained at the minimum

pressure or above. (Not available with KT-70SE)

2.3.4. Automatic Condensate Drain.

If configured, the Automatic Condensate Drain (ACD) will bleed off the condensate

into a separate container on a defined interval.

KT-70E / KT-90E / KT-70SE User Manual Page 16 of 59 24 April 2018

2.4. Functional Description

Standard Equipment

The housing consists of the

base plate with the cover.

Most components are

mounted on the base plate.

The drive consists of a 230V

motor, a pulley and drive

belt. See 115V photo below

The drive can also be a gas

motor with a V-belt pulley

and V-belts.

The compressor block con-

sists of 3 compressor stages.

The filter unit consists of a

high-definition filter and the

condensate drain.

The intake filter is incorpo-

rated in the housing for the

KT-70E / KT-90E.

In the gasoline version of the

KT-70E / KT-90E, a snorkel

may be fitted.

The intake filter for the gaso-

line version of the compres-

sor must be mounted at least

1 m above the compressor.

The filling unit (base config-

uration) consists of: pressure

gauge, safety valve and fill

port. See optional filling

2.5. Pneumatic Air Flow

The compressor has two elements where moisture and / or condensate is removed.

2.5.1. Intermediate Stage Condensate Collector and Drain.

A condensate drain is positioned after the first stage intercooler, prior to the intake for

the second stage.

2.5.2. Final Condensate Collector, Drain and Filter.

The filter housing contains both the Final Condensate Collector as well as the air filter.

One key element used in the condensate collector is the sintered filter. A conical syn-

thetic sintered filter is installed in the base of the filter housing. Air enters the housing

after the 3rd stage and the aftercooler, and flows through the sintered filter where oil and

moisture condense on the interior surface of the sintered filter, and fall to the base of the

condensate collector. The moisture and oil that is captured here are contaminants that

need not be captured by the filter, extending its effective service life.

An additional benefit of using the sintered filter

prior to the filter cartridge is that the air that exits

the sintered filter and flows thru the molecular sieve

filter has an even velocity across the surface of the

filter as it enters the filter. This avoids the creation

of a high velocity path thru the filter material. Con-

stant air velocity permits optimum effectiveness of

and utilization of the molecular sieve material
