II.  PLUMBING HOOK-UP

1) The unit is supplied with compression fittings (Figure 1), USE THESE. DO NOT USE

TAPERED THREADED PIPE FITTINGS AND DO NOT SOLDER TO THE INLET OR
OUTLET. DO NOT USE ANY PIPE DOPE OR TEFLON TAPE WITH THESE
COMPRESSION FITTINGS.

2) Take care to ensure that the pipes are correctly aligned with the inlet and outlet bosses 

in order to avoid excessive stress on the heater body molding.
NOTE: When soldering pipe joints remove heater from the wall. Serious damage can occur

if any soldering is done while pipes are connected to the heater.

Run water through the supply pipe to remove all debris from the pipe before
connecting the heater. Failure to do so could cause damage to the flow switch.

3) Install isolating valves (full flow ball valve type) on both inlet and outlet pipes. This allows unit

to be isolated for maintenance purposes. 

4) When all plumbing is complete, fully check the system for water leaks at all the plumbing 

connections. If a leak is present take corrective action. If the leak is at a compression fitting, 
slowly tighten the compression nut until it stops. Fully open both inlet and outlet BALL VALVES.
Run all the hot water outlets fed by this heater one at a time, for a minute or two, until the water
flow  is continuous, free from “gulping” and from all visible air pockets.
