Condensate Pump - Marstair 929 Series Technical Manual

CONDENSATE PUMP (OPTIONAL)
An optional condensate pump is available, providing a 5m lift where gravity drain is not an option. The full
assembly comprises a condensate pump (suitable for hot and cold water removal), a control board, a float
switch to activate the pump and a second float switch to provide a high water level alarm. The high level
alarm disables cooling until the condensate in the tray has fallen to a safe level.
WATER SPILL SENSOR (OPTION)
Can be connected to the condensate pump board providing an alarm in the event of
condensate spillage.
CD3 SYSTEM HUMIDIFIER (OPTIONAL)
DESCRIPTION
The humidifier is an electrode steam boiler, electronically controlled. The steam bottle will require replacing
periodically. The humidifier is fitted with bottle change indication and the frequency of change is dependent upon
the condition of the water feeding the humidifier.
INSTALLATION
Water supply
The humidifier operates with a range of water qualities; pre-treated water is preferable, extending the bottle life
(fully de-mineralised water is not suitable). The humidifier system incorporates an air break in the water feed to meet
local regulations. Connect directly to a water supply operating at pressures between 0.1 and 1 MPa (14 to 145 psig).
For supplies at higher pressures fit a pressure regulator set at 0.4 to 0.6 MPa (60 to 90 psig).
Plumbing connections
The inlet connection is a 15mm pipe. A stop valve and strainer should be fitted ahead of the control solenoid valve
that is fitted to the inlet of the humidifier.
Waste water is drained into the unit condensate tray. The drainpipe should be suitable for use with water at 60C .
Drain pipes should be correctly sized with a minimum slope of 5% (1 in 20) and an air break at the entry.
