IMPACT-L WALL MOUNTED UNIT INSTALLATION
The IMPACT-L wall mounted unit may be matched with an outdoor condensing unit (550 series), a ducted condensing unit
(542 series), or a heat pump outdoor unit (551 series).
The installer supplies:
*
4 off M6 (or equivalent strength) Rawlbolt shields, bolts and washers.
*
Fully insulated refrigeration pipework.
*
All mains wiring with suitable isolation; Interconnecting wires for indoor and outdoor units.
*
Condensate drain (minimum 10mm bore for gravity drain, 8mm bore for condensate pump drain).
*
Two spanners for securing the flare connectors.
*
A cross-headed screwdriver for releasing the end cover fasteners.
*
A 4 or 5mm Allen key for opening the outdoor/ducted unit valves (depending on valve type).
*
Method for securing solid sheathed cables if these are used.
Unpacking
Carefully unfasten the banding and lift off the outer cardboard carton sleeve.
The following are supplied:
*
IMPACT-L unit (in protective sleeve, held between two polystyrene end caps).
*
A cardboard sleeve containing two pipe assemblies complete with insulation and two cable glands suitable
for flexible, p.v.c. sheathed cable.
*
A wall mounting bracket also held between the two polystyrene end caps.
*
Envelope containing operating instructions to be left with the end user.
Infrared controller, wall mounting bracket, screws and two 1.5V AAA batteries.
1.
Remove and place to one side the cardboard sleeve containing the two pipe assemblies, (and remote control
assembly on IMPACT-L models).
2.
Lift the IMPACT-L unit from the inner cardboard sleeve complete with the two polystyrene end caps; (this will require
2 people for sizes 60 to 100).
3.
Remove the wall mounting bracket and carefully remove the two polystyrene end caps
and the protective sleeve from the IMPACT-L unit.
4.
Remove both end covers by removing the self tapping screws, one on each end trim.
By pulling the end covers sharply they can be removed from the backpanel and fascia.
Chassis Mounting
NOTE:
It is generally easier to fit kits prior to mounting the unit and connecting the pipework.
It is essential to fit a heater kit at this stage if right hand side access will be limited
to less than the unit width.
1.
Ensure that the wall is flat and will support the operating weight of the unit, (see below)
2.
Ensure that sufficient access is left around the unit for future kit fitting, servicing and maintenance (Fig. 1).
Fig. 1.
3.
Mark out the two required top hole centres as shown in Fig. 2, (note that the top of the IMPACT unit will be
approximately 100mm above the level of the hole centres). Drill to suit M6 Rawlbolt shields or equivalent
strength
fasteners. Secure the wall mounting bracket to the upper two holes ensuring that it is level.
4.
Hang the unit on the two protrusions from the wall mounting bracket and, ensuring that the unit is level, mark
out and
drill the lower two holes and secure the unit to the wall.
*Removal or replacement of heater elements
requires a clearance at the right hand side equal
to the length of the unit
