Synergy 4040 - Synergy Sit Shower Shave Kit - Manual (Page 3)

INSTALLATION:
1) **WARNING** be sure vehicle is completely cool before beginning installation.
2) We will begin by assembling the fittings onto the heat exchanger itself.
3) Start first by determining the size of the heater core coolant line which you will be tapping into on the
vehicle. These are commonly 1/2” or 5/8” coolant hoses. The 4040-14 shower fitting kit includes
provisions for tapping into both of these sizes. Disconnect a heater core line and utilizing the brass
barbed fittings, determine which size fits best.
**Caution** Heater core hoses will have coolant in them, so be prepared to catch coolant
when removing.
Draining some of the coolant from the radiator prior to disconnecting a heater core hose
is a good idea to avoid making a mess.
4) Once heater core coolant line size has been determined, assemble the appropriate barbed fittings onto
one side of the heat exchanger. Use a quality thread sealant or Teflon tape on the threads before
assembly.
Snug fittings tight. The fittings are all standard 1/2” NPT threads, so do not over tighten.
Pipe threads of this size are typically assembled 1-2 turns past finger tight. DO NOT
clamp heat exchanger into a vise and crank away. Simply hold the heat exchanger by
hand and tighten as described above using a standard wrench.
After installing the appropriate brass fittings, install the 2 male cam lock fittings on the
opposite side of the heat exchanger which are provided in the kit. Again use a quality
thread sealant or Teflon tape on the threads.
At this point, the heat exchanger should appear as pictured below.
