Installation &

Maintenance

GENERAL
HWP

    

- A general designation which 

 

  applies to all versions (refer fig.1)

These HWP units must be installed in 
accordance with all national and local safety 
codes.

OPtIONs

The following items are available as optional 
extras:
1.  Condensate Lift-Pump Kit.
2.  Filter Box.
High pressure hoses (600 mm long) c/w 
fitting and spring mounts are supplied as 
standard.

AIR FILtRAtION / FILtER BOX (Option)

As air filtration requirements vary, filters are 
not supplied with the unit. Filters should 
ideally be installed on the return air side of 
the unit, no closer than 500 mm from the 
back of the unit and easily accessible for 
cleaning. To maximise the efficiency of air 
flow, the return air filter should be twice the 
area of the HWP unit's return air spigot/s.  If 
efficiency is less of a concern a Filter Box is 
available.

The Filter Box is installed by unscrewing 
the return air spigot and replacing it with the 
Filter Box's filter-integrated spigot. The filter 
may be accessed from either side of this 
spigot. This box adds 90 mm to the overall 
depth of the unit. 

INstALLAtION
Positioning & Mounting

HWP units are designed to be used with 
simple, short duct layouts. Units should 
be located as close to the space to be air 
conditioned as acoustic criteria allows; refer 
to Fig. 6 for application considerations.
When determining the position of the air 
conditioner, allow adequate space around 
the unit to facilitate future servicing and 
maintenance. Ensure there is enough 
working space in front of the electrical 
access panel. Allow adequate clearance for 
the filter (optional) to be withdrawn to its full 
length.

It is recommended that the unit be 
mounted using the spring mount system 
supplied (Fig.3). this system minimises 
transfer of vibration into the building 
structure.

If a more rigid installation can be tolerated, 
then suspend the unit from four threaded 
rods using locknuts (not supplied), as shown 
in Fig. 4.
