OUTLET TEMPERATURE COMPENSATION ADJUSTMENT – RHEEMPLUS
The maximum outlet temperature from the 50°C limited outlet of a RheemPlus
water heater may be adjusted to compensate for temperature losses in the pipe
work between the water heater outlet and fixtures used primarily for personal
hygiene. This adjustment may only be made by a plumber.
Warning: After adjustment of the temperature limiting valve, the water
temperature MUST NOT exceed 50°C from the first tap in the hot water pipe
work connected to the outlet and used primarily for personal hygiene, such as in
a bathroom or ensuite.
To adjust the maximum outlet temperature:
•
Ensure the temperature of the water in the water heater is up to the
thermostat setting on the water heater.
The temperature of the water can be measured at the temperature pressure
relief valve drain discharge point. Do not measure this temperature from a hot
tap
Operate the easing lever on the temperature pressure relief valve and
◼
place the thermometer in the flow of water from the relief valve drain line.
•
Remove the upper plastic casing and insulation covering the pipe work on the
side of the water heater, by removing the three (3) retaining screws, to
expose the temperature limiting valve.
•
Locate the first hot tap in the hot water pipe work after the water heater used
for personal hygiene.
•
Turn on the hot tap fully to achieve maximum flow.
