The 

KD150

  is  designed  for  continuous  duty,  with 

little  maintenance.  However,  when  a  problem 

does  arise  prompt  repair  will  ensure  long  life  for 

the machine.

The blower system is direct drive and the motor has 

sealed high temperature ball bearings. This unit does 

not need regular maintenance.

The air filter should be washed when dirty and 

replaced when necessary. If the filter becomes 

clogged, the air supply will be drastically reduced, 

causing the heater to overheat and the refrigeration 

system to overload. Evap coil should be kept clean. 

Clean with dish soap and water.

The refrigeration system is a sealed system with its 

own oil supply. Again regular maintenance is not 

required. However, if the system is not removing 

the normal amount of water at the appropriate 

conditions, the refrigeration system should be 

looked at by a reputable refrigeration mechanic. 

When the system experiences reduced water 

output, this is generally associated with a leak in the 

refrigeration system. If the leak is found and repaired 

before the system is empty, there is little chance 

that the system will be contaminated with moisture. 

If the system is ignored for a long period of time, 

moisture can enter the system and combine with the 

refrigerant to form acid. The system will then corrode 

from the inside-out if not corrected properly.

The circulating fan system is also direct drive with 

a ball bearing motor. The motor does not require 

lubrication.

The refrigeration system is a closed loop system 

with its own lubrication oil supply. 

We use

 only the 

best trade practices when assembling these 

systems. The system should give years of trouble 

free service. However, if the system is not removing 

the right amount of water, or if a problem should 

arise from rough shipping or a refrigeration leak, 

the system should only be worked on by a 

qualified refrigeration mechanic.

Warning: Refrigeration professionals should 

use caution, these refrigeration conditions are 

uncommon. 

These systems operate over a very wide temperature 

and humidity range. The pressures will be relatively 

high when compared to air conditioners and heat 

pumps. For these reasons, you cannot charge by 

the sight glass, the sight glass will eventually clear 

at certain conditions but it is unlikely that those 

conditions will exist when servicing.

If the kiln is loaded with lumber, it will be very 

dangerous to run the kiln at extreme limits, as the 

lumber will degrade severely. With this danger 

factor and the factor of time involved of heating the 

kiln, 

Wood-Mizer

 insists that these machines have 

weighed in charge. The amount is as follows:

KD150

  20 oz.  RS24

CALL 

WOOD-MIZER

 IF YOUR TECHNICIAN 

LACKS THE RECOMMENDED REFRIGERANT. 

We can recommend alternatives.

The air filters are provided to keep the air inside the 

unit as clean as possible. Dirt build-up on the coils 

will lead to poor heat transfer with loss of capacity. 

In extreme cases, the coil will completely clog. The 

supplied filter is washable and should be replaced 

when worn.
