Installation / Operation Instruction Manual

PLUMBING CONNECTIONS
1) The unit is supplied with 3/8’’ compression fittings. USE THESE: DO NOT
USE THREADED PIPE FITTINGS. DO NOT USE PIPE DOPE OR TEFLON
TAPE ON THIS INSTALLATION. Ensure the inlet filter supplied with this unit
is in place.
2) Ensure that the pipes are correctly aligned with the inlet and
outlet bosses to avoid excessive stress on the heater body molding of the
unit.
NOTE: Run water through the supply pipe to remove all debris from the
pipe before connecting to the unit. Failure to do so could damage the flow
switch.
3) Install isolating valves (shut-off type),or equivalent on both inlet and outlet
pipes. This allows the unit to be isolated for maintenance purposes. (Fig. 2)
4) When all plumbing is complete, inspect the system for water leaks
at all plumbing connections. If a water leak is present take corrective action.
If a water leak is at the compression fitting, slowly tighten compression nut
until the water leaks ceases.
Fully open both inlet and outlet shut-off valves.
Run all hot water outlets fed by this heater one at a time until the water flow
is continuous and free from “gulping” and all visible air pockets.
NOTE:
ALL PLUMBING AND MOUNTING MUST BE COMPLETED
BEFORE PROCEEDING WITH THE
ELECTRICAL HOOK-UP.
TEST THE INSTALLATION FOR LEAKS BEFORE
CONNECTING THE ELECTRICAL SUPPLY.
