Mounting

Securely install the appliance in a location affording easy pip-
ing to the hot water tank.
Install appliance in a frost free area. If frost may occur, remove
appliance before freezing temperatures set in.
Leave a minimum of 5" of clearance on all sides for servicing.
Remove plastic cover.
6 | MEGABOOST
Screw the screws into the wall and hang the appliance. Screws
and plastic wall anchors for mounting on masonry or wood are
provided.
Secure the screws.
9. Water connections
Damage to the appliance and the environment:
!
Excessive heat from soldering on copper pipes near the
MegaBoost may cause damage.
All plumbing work must comply with national and applicable
state and local plumbing codes.
A pressure reducing valve must be installed if the cold water
supply pressure exceeds 150 PSI (10 bar).
Make certain that the cold water supply line has been flushed
to remove any scale and dirt.
Install isolating valve in cold water line as shown in 8.3, "Typi-
cal installation configurations", pg. 5. This allows the appli-
ance to be isolated for maintenance purposes. The tank water
heater should have its own isolation valve in addition to the
valve for the MegaBoost.
Cold water connection (inlet) is on the right side of the ap-
pliance, hot water connection (outlet) is on the left side of
appliance.
Tankless water heaters such as the MegaBoost are not required
to be equipped with a Pressure and Temperature Relief Valve
(P&T). If the local inspector will not pass the installation with-
out a P&T, it should be installed on the hot water outlet side of
appliance.
The appliance is designed for connection to copper tubing, PEX
tubing or a braided stainless steel hose with a ½" NPT female
tapered thread. If soldering near the appliance is necessary,
please direct the flame away from the plastic housing of the
appliance in order to avoid damage. Two couplings that adapts
½˝ to ¾˝ NPT are included with the MegaBoost.
When all plumbing work is completed, check for leaks and take
corrective action before proceeding.

10. Electrical connection

DANGER: Electrocution
Carry out all electrical connection and installation work in
accordance with relevant regulations.
DANGER: Electrocution
Only use a permanent connection to the power supply. The
appliance must be able to be separated from the power
supply by an isolator that disconnects all poles with at least
3 mm contact separation.
