6.2 Heat Pump Operation
Prior to use:
-
i.
Turn off the power supply at the local isolator
ii.
Unscrew the 2 pozi screws on either side of the front panel. Lower the front panel.
iii.
Check that the ground pressure is at least 0.6 bar. If the pressure is lower than this, find the ground
array cold water supply valve (fitted by others, outside the case) fully until the pressure is at least
1.8 bar. Close the mains cold water supply valve fully.
iv.
Check that the heating distribution system pressure is at least 0.6 bar. If the pressure is lower than
this, find the mains cold water supply valve and pressurize the system until the pressure is at least
1.8 bar. Close the mains cold water supply valve fully. Reassemble the front panel taking care to en-
sure that the 2 x cross head screws are located correctly.
v.
Turn on the power supply at the local isolator and program the external timeclock / thermostat.
6.2 Turning the Heat Pump on for the first time.
i.
Make sure the impellor in the ground water pump is free to turn by removing the stainless steel
screw in the centre of each water pump and inserting a flat
-
bladed screwdriver to spin the impellor.
Do not try to spin the impellor with the power on.
ii.
Disconnect the fuse to the compressor (as shown on Fig 14) Turn the Shoebox on to enable the
controls and water pumps to operate.
DO NOT operate the compressor fuse until Kensa Heat
Pumps has been contacted and flow has been confirmed around the system.
Failure to do this
could cause the unit to freeze and may invalidate the warranty. Once flow has been confirmed, turn
the power off and replace the compressor fuse. Turn the power back on.
iii.
The shoebox can be commissioned via an android app downloadable via the links listed in the next
section. The shoebox can also be linked to the home owners Wi
-
Fi to allow remote interrogation of
the Shoebox.
iv.
The heat pump will not run until both heating distribution and ground circuits are above 1.8 bar
pressure.
v.
The commissioning of the heat pump will be carried out remotely (via phone) by a Kensa
commissioning engineer and a heat pump commissioning certificate and checklist issued on
completion. Please contact Kensa Heat Pumps to book a commissioning call.
