WARNING:
!
Open hot water faucet for a few minutes until water
flow is continuous and all air is purged from water
pipes. The unit's cover must be installed before the
circuit breakers are turned on.
1. Turn on circuit breaker to bring electrical power to the unit.
2. Open hot water faucet to a degree so that water flow is „typi-
cal" i.e. until the water flow is the same as that encountered
during normal use.
3. Wait twenty seconds until temperature has stabilized. Then
check water temperature. If temperature is too low, the
water flow rate needs to be reduced. In order to do this,
turn off the unit's circuit breaker, remove the cover and turn
the flow adjustment screw shown in illustration clockwise
1/2 turn (180 degrees). Then reinstall plastic cover, turn
on circuit breaker and check water temperature. This pro-
cedure should be repeated until the desired temperature is
achieved. In case the water temperature is too high, turn the
flow adjustment screw counter clockwise in the same man-
ner until the desired temperature is achieved. The arrows in
illustration refer to the water temperature.
4. In order to obtain temperature control at a single spout mix-
er-type faucet, restrict cold water flow to faucet by partially
closing the cold water shut-off valve under the sink until cold
water and hot water flow rates are approximately the same.
