Installation & Technical Data; Operating Limits - Kingspan KHP0041 Installation And Maintenance Manual

Installation
Before installation, check strength and levelness of the base
so that abnormal sound does not generate. According to
the dimensions and clearances, fix the base firmly with the
anchor bolts (Anchor bolt, nut: M10 x 2 pairs).
Opening cable knockouts
There is a pre-cut part that can be removed for running
wires.Do not remove the unit front panel for easier drilling
of theknockouts. The pre-cut section of the sheet can be
removedby punching the 3 connection points along the
line firstusing a screwdriver and finally with your hands (See
How to remove the front panel
1. Remove screws of the front panel (See fig. 5).
Drain hose and base pan knockouts
See fig. 6.
In case of draining through the drain hose, attach the drain
nipple (A) and use the drain hose (Inner diam: 16mm) sold on
the market. When there is a possibility of freezing of the drain
in cold weather maintain a continuous downward slope in the
drain pipe to prevent the drain becoming blocked by ice.

Radiator Design / Defrost Cycle
The Aeromax Plus system typically requires at least one radiator
(usually located in the same location as the room thermostat) to
remain "open circuit" with no thermostatic radiator valve fitted.
The minimum design criteria to be employed by the installer is to
allow 3 ltr per kW of nominal out of the heat pump.

If the outdoor unit is installed in a very windy place, protect
the fan with a wind protection screen and check that it
works correctly.
When the cable knockout is open, remove the burrs and fit
the cable protective bush supplied with the unit for cable
protection.
2. Pull the front panel downward with the handle.
The drainage ability increases when knockout holes on
the base pan are opened. (Open the knockout hole to
outside using a hammer (B), etc.). Take care not to damage
the evaporator coil when opening the knockout holes. We
recommend that the knockout holes are opened for all UK &
Ireland installations.
For example:
8kW Aeromax Plus x 3ltr = 24 ltr of water to act as open loop.
