INSTALLATION
3.16
Refit the enclosure panels
1. Refer to Figure 16. Refit the FDP right hand and left hand side panels the HMB right hand and left hand side
panels); use the following method for each side panel.
Hold the panel (6) and fit it to the side of the iF system, so that the pins (7) on the frame engage in the slots
at the bottom of the panel.
Lower the panel fully down, then swing the top of the panel into place against the frame.
Use a flat bladed screwdriver to secure the 3 quarter-swing catches (5).

Connect the cooling-water hoses
CAUTION
Drain the cooling-water from the iF system, if you will transport or store it in conditions where the cooling-water
could freeze. If you do not, cooling-water may freeze in the iF system and damage the pump(s) and/or the
cooling-water pipelines.
CAUTION
If cooling water has been interrupted whilst the pump is in operation, do not restore the cooling until the pump
has cooled down to a safe temperature. Restoring the cooling water supply whilst the pump is in operation may
result in FDP seizure.
Notes:
For optimum water-cooling, ensure that your cooling-water supply and return hoses are free of restrictions
which would reduce the cooling-water flow rate. If you need to connect more than one iF system to the
water supply, you must connect them in parallel and not in series.
For minimum water consumption, regulate the cooling-water flow to the iF system.
The positions of the cooling-water connectors are shown in Figure 4. Connect the cooling-water supply as follows:
WARNING
Do not leave the cooling-water supply turned on after you complete the electrical installation of
the pump. If you do, condensation may form inside the motor terminal-box and there may be a risk
of electric shock.
WARNING
A release of water under pressure constitutes a significant safety hazard. The water supply should
be provided with an isolator.
WARNING
Allow the pump to cool down to a safe temperature before disconnecting or isolating the cooling
water supply. Failure to do so will result in high pressures being generated in the pump cooling
system.
