8. MOUNTING & INSTALLATION
8.1
Hang the unit onto the two top wall fixings. Mark through, drill and plug the remaining fixing
holes.
8.2
Referring to Figure 5, determine the method to be used and make the condensate drain pipe
connection to the unit.
8.3
Secure the unit to the wall, using washers under the screw heads if necessary, and complete the
condensate drain system.
8.4
Fit the blanking plate to the base of the unit and secure using 8 screws provided.
8.5
WALL MOUNTED WITH SLIMLINE COOKER HOOD
NOTE:
Refer to the Instructions provided with the Slimline Cooker Hood
8.5.1
Referring to Paragraph 4.1.1 and Figure 6, determine the height (H) of the cooker hood from
the cooker top. Mark the base datum line for the Heat Recovery unit at H + 50 mm.
8.5.2
Position the HR unit such that the base of the unit aligns with the base datum previously
marked and mark the position of the 2 x keyhole fixing points. Remove the HR unit.
NOTE:
It is important that the unit is mounted perfectly horizontally, in order that the condensate
drain shall function effectively.
8.5.3
Drill and plug the 2 x fixing holes and secure the Heat Recovery unit to the wall using suitable
screws (not provided).
NOTE:
For wall types other than masonry, prepare the wall to suit a purpose made fixing.
8.5.4
Referring to Figure 1, remove the front decor panel and gain access to the electrical panel by
removing the electrical panel cover.
8.5.5
Referring to the Installation and User Instructions, fit the CHW or CHS Cooker Hood to the
underside of the HR unit.
8.5.6
Referring to Figure 8, connect the canopy electrical cable as follows:
Brown connector to Terminal Block “BN”,
Blue connector to Terminal Block terminal marked “BL”,
Green/Yellow connector to the common Earth Point.
8.5.7
Refit the electrical panel cover and decor panel to the heat recovery unit.
8.6
MOUNTING IN A LOFT
Mounting Kit MK150 is required for loft applications. These instructions are to be read in conjunction
with those supplied with MK150.
8.6.1 Connect the drainage hose to the condensate drain connection (see paragraph 4.5.1 for
minimum fall) and ensure that steps are taken to minimise the risk of mechanical damage
to the drainage pipework. Run the pipe internally as far as possible and insulate to protect
against freezing.
8.6.2
The drain pipe must terminate outside of the building and must be run as near vertical as
possible into the nearest drain or gutter.
IMPORTANT:
There must be a sufficiently large visible gap between the condensate drain pipe
termination and the collection point, to prevent ice build-up.
