6. OPTIONAL SECONDARY GENERATOR CONTROL
As an option, a second K60 control can be installed
with an AK generator to provide ON/OFF control both
inside and outside the steam room. The second
control should be installed as described in para-
graphs 1 & 5, with the second control cable plugged
into connector S60B for the K60 Control on the
printed circuit board assembly. See diagram 20.
1. DO YOUR BREAKER AND WIRE SIZES MATCH FACTORY/UL SPECS AS PER CHART ON PAGE 9?
2. IF GENERATOR REQUIRES A TEMPERATURE SENSOR, IS THE SENSOR INSTALLED?
3. ARE YOUR CONTROL(S) PLUGGED INTO THE CORRECT JACK(S) ON THE CIRCUIT BOARD?
4. IS POWER SUPPLIED TO ALL CIRCUITS OF STEAMER? (SOME REQUIRE TWO FEEDS)
5. WAS POWER OFF AT THE BREAKER/DISCONNECT WHEN THE CONTROL(S) WERE INSTALLED?
6. IS WATER SUPPLIED TO GENERATOR?
7. IS STEAM LINE PLUMBED TO STEAM ROOM?
8. IS THE AUTOMATIC DRAIN VALVE INSTALLED IN DRAIN OUTLET LINE OR THE BALL VALVE INSTALLED IN A CLOSED POSITION?
QUICK INSTALLATION CHECK LIST
WARNING
The KT60 "must" be mounted inside
the steam room.
Mount the KT60 48" up from steam
room floor.
5. INSTALL GENERATOR CONTROL (K30,K60,KT60)
The low voltage controls can be mounted directly to a finished wall either
inside or outside the steam room with the exception of the KT60 control
which must be mounted inside the steam room. Using a 2" hole saw, drill
a hole in the finished wall where the control is to be mounted (the control
cable should already be roughed-in to this location). With the decorative
cover removed from the control switch assembly, insert the two control
mounting screws through the control housing (may need to punch
through skinned holes) and screw 1/4" into the mounting bracket. Locate
the control cable and plug it into the back of the control housing. See
diagram 18. Run a bead of 100% silicon caulk in-between the 2 ridges
around the perimeter on the back of the control housing. See diagram 19.
Insert the mounting bracket into the wall cavity by first pushing with the
control housing and then with a hard flat surface on the control housing
mounting screws which extend out through the control face. Once the
mounting bracket has been inserted into the finished wall, center the
control and tighten the mounting screws to draw the control housing
securely against the finished wall. Do not over tighten the mounting
screws. Install the decorative cover plate by sliding the top of the cover
plate over the tab on the top of the control housing and pushing on the
bottom of the cover plate to complete the snap fit. See diagram 23. Route
the generator end of the control cable through the generator hole marked
CONTROL WIRING ENTRY using the strain relief provided. Plug the
control cable into the connector on the printed circuit board assembly.
Insert cable into connector S30 if a K30 control is used or connector S60A
if a K60 or KT60 control is used. See diagram 20.
5A. INSTALL GENERATOR CONTROL (R30K)
The low voltage control can be mounted directly to a finished wall either
inside or outside the steam room. Using a 1-3/4" hole saw, drill a hole in
the finished wall where the control is to be mounted (the control cable
should already be roughed-in to this location). Locate the control cable,
pull it out through the
1-3/4" hole and plug the connector on the back of the control housing. Run
a bead of 100% silicone caulk around the perimeter on the back of the
control housing. See diagram 22. Insert the control into the wall cavity.
7. INSTALL TEMPERATURE SENSOR
(REQUIRED FOR K60 OR K30 ONLY)
The temperature sensor should be mounted 6" below the ceiling, inside the steam room,
but not directly over the steam dispersion head or more than 7 feet above the floor. Using
a 7/8" hole saw, drill a hole in the finished wall where the sensor is to be mounted (the
sensor cable should already be roughed-in to this location). Locate the sensor cable, pull
it out through the hole and plug it into the temperature sensor. It is best to tape the sensor
and cable connection together to avoid disconnection inside the wall. Apply silicon caulk
as shown in diagram 24 and insert the sensor in the hole. Make sure that the sensor
probe is pointing down once installed. Tape the sensor in place while the silicone
hardens. Route the generator end of the sensor cable through the generator hole marked
CONTROL WIRING ENTRY using the control cable strain relief. Plug the sensor cable into
the connector marked J4 on the printed circuit board assembly. See diagram 20
8. OPTIONAL CELSIUS OR 24 HOUR OPERATION.
For installations with K60 or KT60 controls, the operation can be changed fro Fahrenheit
to Celsius or 60 minute operation to 24 hours operation by setting the jumpers as shown
below on the generator printed circuit board.
